Abstract
Osteochondral lesion of the talus (OLT) is a common condition associated with ankle injury that brings challenges in the diagnosis and treatment. Symptoms related to this condition are nonspecific including pain, swelling, stiffness, and mechanical symptoms of locking and catching. While the natural history of the OLTs is not well understood, surgical treatment is often required especially in chronic cases and acute cases with displaced articular fragments. Arthroscopic treatment of the OLTs aims to restore ankle joint function and pain relief by the removal of the chondral or osteochondral fragment, debridement and stabilization of cartilage rim and subchondral bone, and stimulate healing of the bone and damaged cartilage. In patients with a large lesion or after a failure of previous bone marrow stimulation, biologic restoration techniques including the use of particulate juvenile cartilage techniques, autogenous chondrocyte implantation, and osteochondral autograft or allograft transplantation may have role. This article summarizes the contemporary concepts in the clinical evaluation and treatment of OLTs with particular emphasis on surgical strategies.

Abstract
OBJECTIVE Healing of articular cartilage is still a challenge due to its limited potential to regenerate. In the present study, we evaluated allogenic bone marrow mesenchymal stem cells (BM-MSCs) alone or in combination with growth factors, insulin-like growth factor-1 (IGF-1) and transforming growth factor-β1 (TGF-β1) in laminin scaffolds for healing of osteochondral defects. DESIGN Osteochondral defects of 4mm (diameter) x 5mm (depth) were induced in the rabbit knee joints and treated with phosphate-buffered saline (PBS; control), BM-MSCs, BM-MSCs in laminin, BM-MSCs in laminin with IGF-1, or BM-MSCs in laminin with IGF-1 and TGF-β1 in 10 animals each. Gross, radiographic, scanning electron microscopic (SEM) and histologic examinations besides chondrocyte-specific genes expression by quantitative real time qPCR were carried out at 8 and 12 weeks. RESULTS Gross and SEM examination revealed superior morphology and surface architecture of the healing site in animals that received MSCs with IGF-1 or IGF-1 and TGF-β1. The application of laminin composites containing MSCs with IGF-1 and TGF-β1 significantly enhanced hyaline cartilage formation with improved cellular arrangement, proteoglycan deposition, clear tidemark zone and subchondral bone formation. However, regenerated tissue in defects that received only MSCs had poor tidemark zone and proteoglycans deposition Aggrecan and Coll2 expression was significantly higher in case of MSCs with growth factors. CONCLUSION The treatment with BM-MSCs combined with IGF-1/TGF-β1 into laminin gel scaffold might enhance the restoration of hyaline cartilage in osteochondral defect.

Abstract
Articular cartilage injury poses a major challenge for both the patient and orthopaedician. Articular cartilage defects once formed do not regenerate spontaneously, rather replaced by fibrocartilage which is weaker in mechanical competence than the normal hyaline cartilage. Mesenchymal stem cells (MSCs) along with different growth factors and scaffolds are currently incorporated in tissue engineering to overcome the deficiencies associated with currently available surgical methods and to facilitate cartilage healing. MSCs, being readily available with a potential to differentiate into chondrocytes which are enhanced by the application of different growth factors, are considered for effective repair of articular cartilage after injury. However, therapeutic application of MSCs and growth factors for cartilage repair remains in its infancy, with no comparative clinical study to that of the other surgical techniques. The present review covers the role of MSCs, growth factors and scaffolds for the repair of articular cartilage injury.

Abstract
El cartílago articular es un tejido vulnerable a las lesiones de diferente etiología; siendo uno de los más afectados, el cartílago de la rodilla. Aunque la mayoría de los tratamientos convencionales reducen los síntomas, generalmente conducen a la formación de fibrocartílago; el cual, posee características diferentes a las del cartílago hialino de las articulaciones. Son pocas las aproximaciones terapéuticas que promueven el reemplazo del tejido dañado por cartílago hialino funcional; las más exitosas son las denominadas terapias avanzadas, que aplican células y productos de ingeniería de tejidos con el fin de estimular la regeneración del cartílago. La mayoría de ellas se basan en colocar soportes hechos con biomateriales de diferente origen, que sembrados o no con células exógenas o endógenas, reemplazan al cartílago dañado y promueven su regeneración. Este trabajo revisa algunas de las aproximaciones terapéuticas enfocadas en la regeneración del cartílago articular de rodilla; así como, los biomateriales más empleados en la elaboración de soportes para terapia celular e ingeniería de tejido cartilaginoso.

Abstract
Osteochondritis dissecans (OCD) of the elbow capitellum is a common disorder that causes pain and functional limitation in the athletic adolescent elbow. Many surgical options have been proposed over the years, but none has stood the test of time. A recent well-written systematic review highlights the treatment options and recognizes a growing trend toward osteochondral allograft transplantation as the ideal solution. Unfortunately, the study also underscores the paucity of evidence on which we base our treatment decisions for OCD of the elbow in the young athlete. Although the potential benefits of osteochondral grafting are encouraging, consideration of associated risks such as donor site morbidity is essential.

Abstract
INTRODUCTION Structural fresh osteochondral allograft transfer is an appropriate treatment option for large osteochondral lesions of the talus (OLTs), specifically lesions involving the shoulder of the talus. Sparse literature exists regarding functional outcome following this surgery in high-demand populations. MATERIALS AND METHODS Over a 2-year period, a single surgeon performed 8 structural allograft transfers for treatment of large OLTs in an active duty US military population. Lesion morphology and magnetic resonance imaging (MRI) stage were recorded. Preoperative and latest postoperative American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot-ankle and pain visual analog scores were compared. RESULTS Eight male service members with mean age 34.4 years underwent structural allograft transfer for OLTs with mean MRI stage of 4.9 and a mean lesion volume of 2247.1 mm3. Preoperative mean AOFAS hindfoot-ankle score was 49.6, and mean pain visual analog score was 6.9. At mean follow-up of 28.5 months, postoperative mean AOFAS score was 73, and mean pain visual analog score was 4.5, representing overall improvements of 47% and 35%, respectively. Three patients were considered treatment failures secondary to continued ankle disability (2) or graft resorption requiring ankle arthrodesis. CONCLUSIONS Despite modest improvements in short-term functional outcome scores, large osteochondral lesions requiring structural allograft transfer remain difficult to treat, particularly in high-demand patient populations. Surgeons should counsel patients preoperatively on realistic expectations for return to function following structural allograft transfer procedures. LEVELS OF EVIDENCE Level IV: Retrospective study.

Abstract
BACKGROUND Osteochondral allograft transplantation (OAT) is being performed with increasing frequency, and the need for reoperations is not uncommon. PURPOSE To quantify survival for OAT and report findings at reoperations. STUDY DESIGN Case series; Level of evidence, 4. METHODS A review of prospectively collected data of 224 consecutive patients who underwent OAT by a single surgeon with a minimum follow-up of 2 years was conducted. The reoperation rate, timing of reoperation, procedure performed, and findings at surgery were reviewed. Failure was defined by revision OAT, conversion to knee arthroplasty, or gross appearance of graft failure at second-look arthroscopic surgery. RESULTS A total of 180 patients (mean [±SD] age, 32.7 ± 10.4 years; 52% male) who underwent OAT with a mean follow-up of 5.0 ± 2.7 years met the inclusion criteria (80% follow-up). Of these, 172 patients (96%) underwent a mean of 2.5 ± 1.7 prior surgical procedures on the ipsilateral knee before OAT. Forty-eight percent of OAT procedures were isolated, while 52% were performed with concomitant procedures including meniscus allograft transplantation (MAT) in 65 (36%). Sixty-six patients (37%) underwent a reoperation at a mean of 2.5 ± 2.5 years, with 32% (21/66) undergoing additional reoperations (range, 1-3). Arthroscopic debridement was performed in 91% of patients with initial reoperations, with 83% showing evidence of an intact graft; of these, 9 ultimately progressed to failure at a mean of 4.1 ± 1.9 years. A total of 24 patients (13%) were considered failures at a mean of 3.6 ± 2.6 years after the index OAT procedure because of revision OAT (n = 7), conversion to arthroplasty (n= 12), or appearance of a poorly incorporated allograft at arthroscopic surgery (n = 5). The number of previous surgical procedures was independently predictive of reoperations and failure; body mass index was independently predictive of failure. Excluding the failed patients, statistically and clinically significant improvements were found in the Lysholm score, International Knee Documentation Committee score, Knee injury and Osteoarthritis Outcome Score, and Short Form-12 physical component summary at final follow-up ( P < .001 for all), with inferior outcomes (albeit overall improved) in patients who underwent a reoperation. CONCLUSION In this series, there was a 37% reoperation rate and an 87% allograft survival rate at a mean of 5 years after OAT. The number of previous ipsilateral knee surgical procedures was predictive of reoperations and failure. Of the patients who underwent arthroscopic debridement with an intact graft at the time of arthroscopic surgery, 82% experienced significantly improved outcomes, while 18% ultimately progressed to failure. This information can be used to counsel patients on the implications of a reoperation after OAT.

Abstract
PURPOSE To assess the histological properties of cells from displaced fragments obtained from patients with advanced osteochondritis dissecans (OCD) of the elbow and to examine whether these displaced fragments could be used as cell sources for autologous chondrocyte implantation. METHODS We harvested 6 displaced fragments from 6 patients who underwent osteochondral mosaicplasty for OCD of the elbow. The displaced fragments were examined histologically and digested to obtain chondrocytes. The cells obtained from young patients and skeletally matured cadaveric donors were examined using quantitative reverse transcription polymerase chain reaction analysis to quantify the expression of chondrocyte marker genes. The cells were cultured in atelocollagen, and the properties of 3-dimensional cultured cartilage were examined. RESULTS All 6 displaced fragments contained hyaline cartilage tissue. Chondrocyte marker genes were examined using cells from only 4 patients, because we obtained enough cells in only 4 patients. The relative expression levels of aggrecan, type II, Sox 9 were 2.61, 4.03, and 1.71, respectively. Three-dimensional cultured cartilage from all 6 displaced fragments contained 62.0 pg/cell (range, 22.8-91.3 pg/cell) of glycosaminoglycan and expressed type II collagen in the superficial and middle layer. CONCLUSIONS The chondrocytes obtained from the displaced fragments remained viable and exhibited chondrogenic features. These cells may potentially be a cell source of autologous chondrocytes implantation. CLINICAL RELEVANCE We have shown that displaced fragments from OCD of the elbow have potential for a cell source for generating 3-dimensional cultured cartilage.

Abstract
Osteochondral lesions of the talus are common injuries that affect a wide variety of active patients. The majority of these lesions are associated with ankle sprains and fractures though several nontraumatic etiologies have also been recognized. Patients normally present with a history of prior ankle injury and/or instability. In addition to standard ankle radiographs, magnetic resonance imaging and computed tomography are used to characterize the extent of the lesion and involvement of the subchondral bone. Symptomatic nondisplaced lesions can often be treated conservatively within the pediatric population though this treatment is less successful in adults. Bone marrow stimulation techniques such as microfracture have yielded favorable results for the treatment of small (<15 mm) lesions. Osteochondral autograft can be harvested most commonly from the ipsilateral knee and carries the benefit of repairing defects with native hyaline cartilage. Osteochondral allograft transplant is reserved for large cystic lesions that lack subchondral bone integrity. Cell-based repair techniques such as autologous chondrocyte implantation and matrix-associated chondrocyte implantation have been increasingly used in an attempt to repair the lesion with hyaline cartilage though these techniques require adequate subchondral bone. Biological agents such as platelet-rich plasma and bone marrow aspirate have been more recently studied as an adjunct to operative treatment but their use remains theoretical. The present article reviews the current concepts in the evaluation and management of osteochondral lesions of the talus, with a focus on the available surgical treatment options.

Abstract
PURPOSE The purpose of this study is to present a systematic review of the literature regarding the use of fresh bulk osteochondral allograft transfer for treatment of large osteochondral lesions of the talus (OCLT) in an effort to characterize the functional outcomes, complications, and reoperation rates. METHODS A search of the PubMed, CINAHL, Embase, and Cochrane Databases was performed between January 1, 1990, and March 1, 2016, and included all articles related to outcomes after fresh talar allograft transplantation for OCLT. Inclusion criteria were series (1) published in the English language, (2) using fresh talar allograft, and (3) reporting at least one outcome measure of interest including American Orthopaedic Foot and Ankle Society (AOFAS) score, pain visual analog scale (VAS) score, reoperation rate, and rate of allograft collapse. Weighted averages of outcome data were used. RESULTS Five studies involving 91 OCLT met the inclusion criteria. The mean age of the cohort was 39 years (range, 15 to 74), and 53% were male. Fresh talar allograft was transplanted into 71 medial, 18 lateral, and 2 central OCLT. At a mean follow-up of 45 ± 3.3 (range, 6 to 91) months, AOFAS scores improved from 48 preoperatively to 80 postoperatively. Pain VAS scores improved from 7.1 preoperatively to 2.7 postoperatively. Twenty-three of the 91 (25%) patients required at least one reoperation, for a total of 28 operations. The most common indications for reoperation were development of moderate to severe osteoarthritis (14%), pain due to hardware (9%), extensive graft collapse (3%), and delayed or nonunion of osteotomy site (1%). Ultimately 12 (13.2%) of the cases were considered failures, with 8 (8.8%) resulting in tibiotalar arthrodesis or ankle replacement. CONCLUSIONS Fresh bulk allograft transplantation can substantially improve functional status as well as effectively prevent or delay the eventual need for ankle arthrodesis or replacement. However, patients must be carefully selected and counseled on the morbidity of the procedure as well as the high incidence of clinical failure (13%) and need for reoperation (25%) and revision surgery (8.8%).

Abstract
PURPOSE To determine the rate of donor-site morbidity after osteochondral autologous transplantation (OATS) for capitellar osteochondritis dissecans. METHODS A literature search was performed in PubMed/MEDLINE, Embase, and Cochrane Library to identify studies up to November 6, 2016. Criteria for inclusion were OATS for capitellar osteochondritis dissecans, reported outcomes related to donor sites, ≥10 patients, ≥1 year follow-up, and written in English. Donor-site morbidity was defined as persistent symptoms (≥1 year) or cases that required subsequent intervention. Patient and harvest characteristics were described, as well as the rate of donor-site morbidity. A random effects model was used to calculate and compare weighted group proportions. RESULTS Eleven studies including 190 patients were included. In eight studies, grafts were harvested from the femoral condyle, in three studies, from either the 5th or 6th costal-osteochondral junction. The average number of grafts was 2 (1-5); graft diameter ranged from 2.6 to 11 mm. In the knee-to-elbow group, donor-site morbidity was reported in 10 of 128 patients (7.8%), knee pain during activity (7.0%) and locking sensations (0.8%). In the rib-to-elbow group, one of 62 cases (1.6%) was complicated, a pneumothorax. The proportion in the knee-to-elbow group was 0.04 (95% CI 0.0-0.15), and the proportion in the rib-to-elbow group was 0.01 (95% CI 0.00-0.06). There were no significant differences between both harvest techniques (n.s.). CONCLUSIONS Donor-site morbidity after OATS for capitellar osteochondritis dissecans was reported in a considerable group of patients. LEVEL OF EVIDENCE Level IV, systematic review of level IV studies.

[PMID: 27813019 PMCID: PMC5095115 DOI: 10.1186/s40634-016-0066-0] [Citation(s) in RCA: 76] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2016] [Accepted: 10/24/2016] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Mosaicplasty has been associated with good short- to long-term results. Nevertheless, the osteochondral harvesting is restricted to the donor-site area available and it may lead to significant donor-site morbidity. PURPOSE Provide an overview of donor-site morbidity associated with harvesting of osteochondral plugs from the knee joint in mosaicplasty procedure. METHODS Comprehensive search using Pubmed, Cochrane Library, SPORTDiscus and CINAHL databases was carried out through 10th October of 2016. As inclusion criteria, all English-language studies that assessed the knee donor-site morbidity after mosaicplasty were accepted. The outcomes were the description and rate of knee donor-site morbidity, sample's and cartilage defect's characterization and mosaicplasty-related features. Correlation between mosaicplasty features and rate of morbidity was performed. The methodological and reporting quality were assessed according to Coleman's methodology score. RESULTS Twenty-one studies were included, comprising a total of 1726 patients, with 1473 and 268 knee and ankle cartilage defects were included. The defect size ranged from 0.85 cm2 to 4.9 cm2 and most commonly 3 or less plugs (averaging 2.9 to 9.4 mm) were used. Donor-site for osteochondral harvesting included margins of the femoral trochlea (condyles), intercondylar notch, patellofemoral joint and upper tibio-fibular joint. Mean donor-site morbidity was 5.9 % and 19.6 % for knee and ankle mosaicplasty procedures, respectively. Concerning knee-to-knee mosaicplasty procedures, the most common donor-site morbidity complaints were patellofemoral disturbances (22 %) and crepitation (31 %), and in knee-to-ankle procedures there was a clear tendency for pain or instability during daily living or sports activities (44 %), followed by patellofemoral disturbances, knee stiffness and persistent pain (13 % each). There was no significant correlation between rate of donor-site morbidity and size of the defect, number and size of the plugs (p > 0.05). CONCLUSIONS Osteochondral harvesting in mosaicplasty often results in considerable donor-site morbidity. The donor-site morbidity for knee-to-ankle (16.9 %) was greater than knee-to-knee (5.9 %) mosaicplasty procedures, without any significant correlation between rate of donor-site morbidity and size of the defect, number and size of the plugs. Lack or imcomplete of donor-site morbidity reporting within the mosaicplasty studies is a concern that should be addressed in future studies. LEVEL OF EVIDENCE Level IV, systematic review of Level I-IV studies.

Osteochondral transplantation of autologous graft for the treatment of osteochondral lesions of talus: 5- to 7-year follow-up. Knee Surg Sports Traumatol Arthrosc 2016; 24:3722-3729. [PMID: 25326766 DOI: 10.1007/s00167-014-3389-3] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2014] [Accepted: 10/10/2014] [Indexed: 12/27/2022]
Abstract
PURPOSE Bone marrow stimulation procedures (microfractures/drilling) are considered the gold standard for the primary treatment of osteochondral talar lesions. In the literature, there is lack of evidence about the appropriate treatment in cases of failure of these procedures. A technique of osteochondral autologous transplantation of talar graft was used. It was hypothesized that this is a successful method with good results and low complication rates. Additionally, a technique of anterior ankle approach with temporary removal of a bone block from the distal tibia that gives adequate access to posterior talar dome lesions is demonstrated. METHODS Between 2004 and 2007, 46 patients (37 males, 9 females), with OLT for which arthroscopic treatment with curettage and drilling or microfracture had failed, underwent osteochondral transplantation with an osteochondral graft harvested from the ipsilateral talar articular facet. A medial malleolar osteotomy or a distal tibial wedge osteotomy was used to access the talar dome defect. RESULTS The median follow-up time was 5.5 years (range 52-75 m). Thirty-four lesions (70.8 %) were located in the central talar dome in the coronal plane, while 26 (54.1 %) and 19 (39.5 %) lesions were located in the lateral and medial aspect of talar dome in saggital plane, respectively. The overall improvement between the preoperative and post-operative AOFAS and VAS FA score was 35 points (p < 0.001) and 39 points (p < 0.001), respectively. Clinical results were considered as good in 43 patients (93.4 %) and fair in three patients (6.5 %). All the transplanted grafts were observed to incorporate fully into the recipient bed. No complications occurred at the site of the malleolus osteotomy or tibial osteotomy and the donor site at the talus. CONCLUSIONS The midterm results suggest that the technique of osteochondral transplantation of autologous talar graft for osteochondral lesions of talus after failure of primary treatment with bone marrow stimulation can be safely and successfully used. It demonstrates excellent post-operative scores including improvement of pain and function. This procedure is combined with removal of a tibial bone block and its subsequent replacement and does not yield complications experienced with other procedures.

Abstract
BACKGROUND Osteochondritis dissecans (OCD) of the capitellum is a rare yet debilitating injury seen in young athletes. This is the first report in the literature describing fresh osteochondral allograft transplantation (FOCAT) to treat OCD of the capitellum. METHODS Nine male baseball players (mean age, 15.3; range, 14-18 years), with OCD of the capitellum were treated with FOCAT. There were 6 pitchers and 3 position players. A ligament-sparing, mini-open approach was used. A fresh femoral hemicondyle was used as a donor source. Of the 9 patients, 7 required 1 plug and 2 required 2 plugs. The average plug diameter was 11 mm (range, 8-18 mm). Five plugs were press fit, and 4 required additional fixation. Clinical outcomes were evaluated at a mean follow-up of 48.4 months (range, 11-90 months). Preoperative and postoperative outcome scores were calculated using the paired t test. RESULTS The Mayo Elbow Performance score improved from an average 57.8 to 98.9 (P < .01). The Oxford Elbow Score improved from 22.4 to 44.8 (P < .01). The Disabilities of the Arm, Shoulder and Hand score improved from 35.2 to 5.4 (P < .01). The visual analog scale score improved from 7.8 to 0.5 (P < .01). The Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score improved from 32.6 to 82.5 (P < .01). All patients returned to throwing and were still active in their sport or played at least 2 years of baseball before leaving the sport unrelated to the elbow. CONCLUSIONS FOCAT for OCD of the capitellum in properly selected cases is a viable treatment with significant functional improvement and pain reduction in throwers.

Abstract
BACKGROUND Large cystic osteochondral defects of the talus can be challenging to treat. This retrospective control study looked at the use of osteochondral autograft transfer combined with cancellous allograft in patients with advanced cartilage and subchondral bone damage of the talus. METHODS Thirteen patients were treated with large cystic osteochondral defect of the talus between February 2010 and July 2013. All of these cystic osteochondral defects were larger than 15 mm in diameter. The subchondral defects were filled with cancellous allograft and the center of the lesions were sealed with an osteochondral cylinder autograft that was harvested from the ipsilateral medial femoral condyle. The visual analog scale (VAS) score for pain during daily activities, American Orthopaedic Foot & Ankle Society Ankle and Hindfoot (AOFAS-AH) scores and subjective satisfaction survey rating were obtained. Plain radiographs and magnetic resonance imaging of the ankle were obtained before and after surgery. In 5 cases, arthroscopy was performed 12 months postoperatively, and the cartilage repair was assessed with the criteria of the International Cartilage Repair Society. Twelve patients were available for follow-up at a mean of 25.4 months (range, 18 to 48 months). RESULTS Average postoperative AOFAS-AH score 12 months after surgery was 88±7 compared with 64±10 preoperatively. The mean VAS score decreased from 6±1 preoperatively to 1±1 at the latest follow-up. Seven patients rated their result as excellent, 5 as good and none as fair. The radiolucent area of the cysts disappeared on the plain radiographs in all cases. The mean International Cartilage Repair Society arthroscopic score from follow-up arthroscopy was 9±1 points. CONCLUSIONS The use of osteochondral autograft transfer combined with cancellous allograft was an effective option for the treatment of large cystic talar osteochondral lesions.

Abstract
BACKGROUND Autologous osteochondral transplantation (AOT) has an inherent risk of donor site morbidity (DSM). The reported rates of DSM vary from 0% to 50%, with few studies reporting clinical or imaging outcomes at the donor site as a primary outcome and even fewer report these outcomes when a biosynthetic plug backfill is employed. Although TruFit (Smith & Nephew, Andover, MA) plugs have been removed from the market for regulatory purposes, biphasic plugs (including TruFit plugs) have been used for several years and the evaluation of these is therefore pertinent. METHODS Thirty-nine patients who underwent forty AOT procedures of the talus, with the donor graft being taken from the ipsilateral knee, were included. Postoperative magnetic resonance imaging (MRI) was used to assess the donor site graded with magnetic resonance observation of cartilage repair tissue (MOCART) scoring. Lysholm scores were collected preoperatively, at the time of magnetic resonance imaging (MRI), and again at 24 months and at final follow-up to assess clinical outcomes. Statistical analysis was performed to establish if there was any correlation between MRI assessment of the donor site and clinical outcomes. The mean patient age was 36.2 ± 15.7 years with a mean follow-up of 41.8 ± 16.7 months. RESULTS All patient donor site defects were filled with OBI TruFit biphasic plugs. DSM was encountered in 12.5% of the patient cohort at 24 months, and in these patients, the Lysholm score was a mean 87.2 ± 5.0. At final follow-up, DSM was reduced to 5%. Lysholm scores for the entire cohort were 98.4 ± 4.6 and 99.4 ± 3.1 at 24 months and final follow-up, respectively. MRI of the donor sites were taken at an average of 18.1 ± 13.5 (range, 3-48) months postoperatively and the mean MOCART score was 60.0 ± 13.5. No correlation was found between the MOCART score and Lysholm outcomes at the donor knee (P = .43, r = 0.13). CONCLUSION Low incidence of DSM and good functional outcomes were achieved with AOT. Additionally, MRI findings did not predict clinical outcomes in our study. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
The aim of the present study was to clinically evaluate whether the presence of subchondral cysts had an effect on the treatment results of autologous osteochondral graft transfer in osteochondral lesions of the talus. Patients were enrolled in the present study according to the inclusion criteria. In the evaluation, we divided the patients into 2 groups according to presence (n = 13 patients) or absence (n = 15 patients) of a subchondral cyst. The mean age, body mass index, follow-up period, and lesion size in each group were measured and compared, and no statistically significant differences were found between the 2 groups (p > .05). The clinical assessment was performed using the American Orthopaedic Foot and Ankle Society Hindfoot scoring system, visual analog scale, and International Knee Society scoring system. No statistically significant difference was found between the pre- and postoperative scores of the 2 patient groups (p > .05). The successful results in both groups after a 2-year follow-up period have demonstrated that treatment of osteochondral lesions of the talus with osteochondral graft transfer is a safe method that can be performed independently of the presence of a subchondral cyst.

Abstract
BACKGROUND Autologous osteochondral transplantation (AOT) is used to treat osteochondral lesions (OCLs) of the talus, typically reserved for lesions greater than 150 mm(2). Few studies exist examining the functional and magnetic resonance imaging (MRI) outcomes following this procedure. The purpose of this study was to investigate functional and MRI outcomes, including quantitative T2 mapping following AOT. METHODS Eighty-five consecutive patients who underwent AOT were identified. Functional outcomes were assessed pre- and postoperatively using the Foot and Ankle Outcome Score (FAOS). The Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score was used to assess cartilage incorporation. Quantitative T2 MRI relaxation time of graft tissue and adjacent normal cartilage values were recorded in a subset of 61 patients. The mean clinical follow-up was 47.2 months, with mean MRI follow-up of 24.8 months. RESULTS Mean FAOS improved pre- to postoperatively from 50 to 81 (P < .001). The mean MOCART score was 85.8. Lesion size was negatively correlated with MOCART score (r = -0.36, P = .004). Superficial T2 values in graft tissue were higher than control tissue (42.0 vs 35.8, P < .001). Deep T2 values in graft tissue were similar to the control values (30.9 vs 30.0, P = .305). Functional outcomes were similar in patients irrespective of whether they had previous microfracture or concomitant procedures. CONCLUSION AOT was an effective treatment for large OCLs of the talus in the current study. MOCART scoring indicated good structural integrity of the graft. Quantitative T2 mapping suggests that graft tissue may not always mirror native hyaline cartilage. The long-term implications of this are not yet known. LEVEL OF EVIDENCE Level IV, case series.

Abstract
Engineering of large articular cartilage tissue constructs remains a challenge as tissue growth is limited by nutrient diffusion. Here, a novel strategy is investigated, generating large constructs through the assembly of individually cultured, interlocking, smaller puzzle-shaped subunits. These constructs can be engineered consistently with more desirable mechanical and biochemical properties than larger constructs (~4-fold greater Young׳s modulus). A failure testing technique was developed to evaluate the physiologic functionality of constructs, which were cultured as individual subunits for 28 days, then assembled and cultured for an additional 21-35 days. Assembled puzzle constructs withstood large deformations (40-50% compressive strain) prior to failure. Their ability to withstand physiologic loads may be enhanced by increases in subunit strength and assembled culture time. A nude mouse model was utilized to show biocompatibility and fusion of assembled puzzle pieces in vivo. Overall, the technique offers a novel, effective approach to scaling up engineered tissues and may be combined with other techniques and/or applied to the engineering of other tissues. Future studies will aim to optimize this system in an effort to engineer and integrate robust subunits to fill large defects.

Abstract
OBJECTIVE To establish if harvesting cartilage to source chondrocytes for autologous chondrocyte implantation (ACI) results in donor site morbidity. DESIGN Twenty-three patients underwent ACI for chondral defects of either the ankle or the hip. This involved cartilage harvest from the knee (stage I), chondrocyte expansion in the laboratory and implantation surgery (stage II) into the affected joint. Prior to chondral harvest, no patient had sought treatment for their knee. Lysholm knee scores were completed prior to chondral harvest and annually post-ACI. Histological analyses of the donor site were performed at 12.3 ± 1.5 months for 3 additional patients who had previously had ACI of the knee. RESULTS The median preoperative Lysholm score was 100, with no significant differences observed at either 13.7±1.7 months or 4.8±1.8 years postharvest (median Lysholm scores 91.7 and 87.5, respectively). Patients whose cartilage was harvested from the central or medial trochlea had a significantly higher median Lysholm score at latest follow-up (97.9 and 93.4, respectively), compared with those taken from the intercondylar notch (median Lysholm score 66.7). The mean International Cartilage Repair Society (ICRS) II histological score for the biopsies taken from the donor site of 3 additional knee ACI patients was 117 ± 10 (maximum score 140). CONCLUSIONS This study suggests that the chondral harvest site in ACI is not associated with significant joint morbidity, at least up to 5 years postharvest. However, one should carefully consider the location for chondral harvest as this has been shown to affect knee function in the longer term.

Abstract
PURPOSE The purpose of this study was to assess the effect(s) of platelet-rich plasma (PRP) on osteochondral donor site healing in a rabbit model. METHODS Osteochondral donor sites 3 mm in diameter and 5 mm in depth were created bilaterally on the femoral condyles of 12 New Zealand White rabbits. Knees were randomized such that one knee in each rabbit received an intra-articular injection of PRP and the other received saline (placebo). Rabbits were euthanized at 3, 6, and 12 weeks following surgery. Repair tissue was evaluated using the International Cartilage Repair Society (ICRS) macroscopic and histological scores. RESULTS No complications occurred as a result of the interventions. There was no significant difference in macroscopic scores between the 2 groups (5.5 ± 3.8 vs. 3.8 ± 3.5; P = 0.13). Subjective macroscopic assessment determined greater tissue infill with fewer fissures and a more cartilage-like appearance in PRP-treated knees. Overall ICRS histological scores were better in the PRP group compared with the placebo (9.8 ± 2.0 vs. 7.8 ± 1.8; P = 0.04). Histological scores were also higher in the PRP group compared with the placebo group at each time point. Greater glycosaminoglycan and type II collagen content were noted in the repair tissue of the PRP group compared with the placebo group. CONCLUSION The results of this study indicate that PRP used as an intra-articular injection may improve osteochondral healing in a rabbit model.

Abstract
BACKGROUND The purpose of this study was to prospectively evaluate and compare the long-term clinical and radiographic outcomes of using osteochondral autograft and allograft to manage either recurrent or large osteochondral lesions of the talar dome (OLT) in a single surgeon's practice. METHODS Between January 2008 and January 2014, a total of 40 patients presented with either a recurrent OLT that failed initial arthroscopic treatment (ie, excision, curettage, debridement, and micro-fracture) or a primary OLT greater than 1.5 cm2 that had undergone no prior surgery. Before surgery, 20 patients were randomized to receive osteochondral autograft plugs (Arthrex, Naples, FL) from the ipsilateral superolateral distal femoral condyle whereas the remaining 20 were randomized to receive osteochondral allograft plugs from a fresh size-matched donor talus (Joint Restoration Foundation, Centennial, CO, and Arthrex, Naples, FL), but 4 of these were excluded that received a hemi-talus allograft with internal fixation. Preoperative and postoperative function and pain was graded using the Foot and Ankle Ability Measures (FAAM) scoring system and a Visual Analog Scale (VAS) of pain, respectively. Radiographs were assessed for osteochondral graft healing, joint congruency, and degenerative changes. Data regarding postoperative complications and revision surgeries were also recorded. RESULTS Of the 20 patients who received osteochondral autograft, the mean FAAM score increased from 54.4 preoperatively to 85.5 at the time of final follow-up. The mean VAS pain score decreased from 7.9 of 10 preoperatively to 2.2 of 10 at final follow-up. Two patients (10%) that received osteochondral autograft, 1 for a recurrent OLT of 1.3 cm2 and 1 for a primary OLT of 2.0 cm2, developed a symptomatic nonunion at the entire graft site. Both of these patients had their autograft converted to talar allograft plugs and achieved full osteochondral healing. At the time of final follow-up, no patients who received osteochondral autograft developed ankle degenerative changes or knee complications. The mean FAAM score of the 16 patients who received osteochondral allograft plugs increased from 55.2 preoperatively to 80.7 at the time of final follow-up. This postoperative score was lower than that of the osteochondral autograft group, but not to a statistically significant degree (P = .25). The mean VAS pain score decreased from 7.8 of 10 preoperatively to 2.7 of 10 at final follow-up. This postoperative score was higher than that of the osteochondral autograft group but not to a statistically significant degree (P = .15). Three patients (18.8%) that received osteochondral talar allograft, 2 for recurrent OLTs less than 1.5 cm2 and 1 for a primary OLT of 2.2 cm2, developed a symptomatic nonunion at the entire graft site. Two of these 3 patients had their allograft converted to osteochondral autograft plugs harvested from the ipsilateral superolateral distal femoral condyle and achieved full osteochondral healing. At the time of final follow-up, 1 of these 16 (6.3%) patients who received talar allograft as OLT treatment had developed asymptomatic anterior ankle arthritis upon radiographs. CONCLUSION Using fresh talar osteochondral allograft provided results that were comparable to the use of distal femoral osteochondral autograft for treating recurrent or large OLTs. Although the use of allograft avoided the risk of knee complications when harvesting autograft from the distal femur, fresh talar allograft may have lower healing rates than osteochondral autograft.

Abstract
PURPOSE Matrix-induced autologous chondrocyte implantation (MACI) has demonstrated effectiveness in treating isolated cartilage defects of the knee but medium- and long-term evidence and information on the management of postoperative complications or partially successful cases are sparse. This study hypothesised that MACI is effective for up to 5 years and that patients with posttreatment problems may go on to obtain clinical benefit from other interventions. METHODS A follow-on, prospective case series of patients recruited into a previous controlled, randomised, prospective study or newly enroled. Patients were followed up 6, 12, 24 and 60 months after surgery. Outcome measures were Tegner (activity levels) and Lysholm (pain, stability, gait, clinical symptoms) scores. Zone-specific subgroups were analysed 6, 12 and 24 months postoperatively. RESULTS Sixty-five patients were treated with MACI. Median Tegner score improved from II to IV at 12 months; an improvement maintained to 60 months. Mean Lysholm score improved from 28.5 to 76.6 points (±19.8) at 24 months, settling back to 75.5 points after 5 years (p > 0.0001). No significant differences were identified in the zone-specific analysis. Posttreatment issues (N = 12/18.5 %) were resolved with microfracture, debridement, OATS or bone grafting. CONCLUSIONS MACI is safe and effective in the majority of patients. Patients in whom treatment is only partially successful can go on to obtain clinical benefit from other cartilage repair options. This study adds to the clinical evidence on the MACI procedure, offers insight into likely treatment outcomes, and highlights MACI's usefulness as part of an armamentarium of surgical approaches to the treatment of isolated knee defects. LEVEL OF EVIDENCE Prospective case control study with no control group, Level III.

Abstract
Osteochondritis dissecans (OCD) of the femoral head is not a common source of hip pain. Hip arthroscopy is becoming a more frequent indication for intra-articular pathologies of the hip. Osteochondral autologous transplantation is a promising technique that theoretically can reconstruct osteochondral lesions of the femoral head. We describe our technique for arthroscopic antegrade osteochondral autologous transplantation for the treatment of OCD of the femoral head. The advantages of this technique include that it is a less invasive method with the ability to assess and treat intra-articular pathologies associated with OCD of the femoral head at same time. Case series and outcomes after this technique are not currently reported in the literature; however, it could be a less invasive method and provide favorable clinical outcomes for patients with OCD lesions of the femoral head.

Abstract
Tissue engineering of osteochondral grafts may offer a cell-based alternative to native allografts, which are in short supply. Previous studies promote the fabrication of grafts consisting of a viable cell-seeded hydrogel integrated atop a porous, bone-like metal. Advantages of the manufacturing process have led to the evaluation of porous titanium as the bone-like base material. Here, porous titanium was shown to support the growth of cartilage to produce native levels of Young's modulus, using a clinically relevant cell source. Mechanical and biochemical properties were similar or higher for the osteochondral constructs compared to chondral-only controls. Further investigation into the mechanical influence of the base on the composite material suggests that underlying pores may decrease interstitial fluid pressurization and applied strains, which may be overcome by alterations to the base structure. Future studies aim to optimize titanium-based tissue engineered osteochondral constructs to best match the structural architecture and strength of native grafts. STATEMENT OF SIGNIFICANCE The studies described in this manuscript follow up on previous studies from our lab pertaining to the fabrication of osteochondral grafts that consist of a bone-like porous metal and a chondrocyte-seeded hydrogel. Here, tissue engineered osteochondral grafts were cultured to native stiffness using adult chondrocytes, a clinically relevant cell source, and a porous titanium base, a material currently used in clinical implants. This porous titanium is manufactured via selective laser melting, offering the advantages of precise control over shape, pore size, and orientation. Additionally, this manuscript describes the mechanical influence of the porous base, which may have applicability to porous bases derived from other materials.

Abstract
BACKGROUND Osteochondral Autologous Transplant (OATs) as a treatment option for Osteochondral lesions (OCLs) of the talar dome frequently uses the distal femur as the donor site which is associated with donor site morbidity in up to 50%. Some studies have described the presence of hyaline cartilage in the posterior superior calcaneal tuberosity. The aim of this study was to evaluate the posterior superior calcaneal tuberosity to determine if it can be a suitable donor site for OATs of the talus METHODS In this cadaveric study, we histologically evaluated 12 osteochondral plugs taken from the posterior superior calcaneal tuberosity and compared them to 12 osteochondral plugs taken from the talar dome. RESULTS In the talar dome group, all samples had evidence of hyaline cartilage with varying degrees of GAG staining. The average hyaline cartilage thickness in the samples was 1.33 mm. There was no evidence of fibrocartilage, fibrous tissue or fatty tissue in this group. In contrast, the Calcaneal tuberosity samples had no evidence of hyaline cartilage. Fibrocartilage was noted in 3 samples only. CONCLUSIONS We believe that the structural differences between the talus and calcanium grafts render the posterior superior clancaneal tuberosity an unsuitable donor site for OATs in the treatment of OCL of the talus.

Abstract
PURPOSE To investigate the clinical and radiologic outcomes of an autologous osteoperiosteal cylinder graft from the medial tibia for the treatment of large cystic medial osteochondral lesions (OCLs) of the talus. METHODS The study included 15 patients with large cystic medial OCLs. All underwent medial malleolus osteotomy and excision and curettage of the defect site, followed by transplantation with an autologous osteoperiosteal cylinder graft from the medial tibia. They were evaluated preoperatively and after a minimum of 24 months (mean, 44.8 months; range, 24 to 72 months) postoperatively by a visual analog scale, the American Orthopaedic Foot & Ankle Society ankle-hindfoot scale, the Ogilvie-Harris scale, and magnetic resonance imaging of the ankle. RESULTS The mean visual analog scale score decreased from 5.40 ± 1.06 points to 1.00 ± 1.00 points (P < .001), and the mean American Orthopaedic Foot & Ankle Society score increased from 49.00 ± 8.96 points to 89.00 ± 4.17 points (P < .001). The mean Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score was 64.00 ± 5.07 points. According to the Ogilvie-Harris scale, 7 cases were rated as excellent, 5 as good, 3 as fair, and 0 as poor. No complications were observed. CONCLUSIONS An autologous osteoperiosteal cylinder graft from the medial tibia is effective for treating large cystic medial OCLs of the talus and has a low rate of complications.

Topographic analysis of the capitellum and distal femoral condyle: finding the best match for treating osteochondral defects of the humeral capitellum. Arthroscopy 2015; 31:843-9. [PMID: 25636985 DOI: 10.1016/j.arthro.2014.11.039] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2014] [Revised: 11/10/2014] [Accepted: 11/21/2014] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study was to determine the donor zone of most congruent topographic match by comparing 4 donor sites from the femur with 4 potential recipient sites of osteochondritis dissecans at the capitellum. METHODS Computed tomography was performed on 5 right elbows and 6 right medial and 6 right lateral distal femoral hemicondyles, which included the femoral notch. Three-dimensional computed tomography models were created and exported into point-cloud models. A local coordinate map of the distal humerus and distal femoral articular surfaces was created. The capitellum was compared with the medial and lateral distal femoral condyles, with 2 donor zones in each condyle (medial trochlea and medial intercondylar notch or lateral trochlea and lateral intercondylar notch). In each capitellum 4 combinations of 10-mm defects were simulated (central and lateral, 30° and 45° anterior to shaft of humerus), resulting in 480 capitellum-femur comparative combinations being tested. The capitellum surfaces were virtually placed on a point on the femoral articular surface in 3-dimensional space. The least distances (i.e., the shortest distance from the point in question to the corresponding point in space) between the point clouds on the distal humerus and distal femoral articular surfaces were calculated. RESULTS There was a less than 0.1-mm difference in the topographic articular surface match among the 4 commonly used donor sites of the distal femur and 4 recipient sites of the capitellum. However, the best match for any given 10-mm capitellar defect (central 30°, central 45°, lateral 30°, and lateral 45°) was the same such that the lateral trochlea on the femur always yielded the best fit compared with the 3 other graft locations (P < .005). CONCLUSIONS Our results indicate that there is a less than 0.1-mm difference in the topographic articular surface match among the 4 commonly used donor sites of the distal femur and the capitellum. The findings suggest that all 4 donor sites provide close articular matching for the capitellum articular surface, with the lateral trochlea articular surface providing the best match. CLINICAL RELEVANCE These data suggest that a single donor plug may be obtained from multiple sites in the knee and placed into capitellar lesions with an excellent topographic articular surface match. The findings of our study will be useful to surgeons when managing capitellar osteochondritis dissecans lesions.

Knee Surg Sports Traumatol Arthrosc 2015; 23:1401-1409. [PMID: 24488222 DOI: 10.1007/s00167-014-2853-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2013] [Accepted: 01/12/2014] [Indexed: 10/25/2022]
Abstract
PURPOSE The purpose of this study was to identify the optimal material and implantation method for subchondral bone repair. METHODS Four osteochondral defects in a femoral groove were created in both knees of 12 pigs, and the total number of defects was 96. Eight defects were left empty (empty group). Beta-tricalcium phosphate (β-TCP) bone substitutes with 75 and 67 % porosity were implanted in 30 and 29 defects, respectively (β-TCP75 and β-TCP67 groups). Hydroxyapatite (HA) bone substitutes with 75 % porosity were filled in 29 defects (HA group). Bone substitutes were implanted at 0, 2, or 4 mm below the subchondral bone plate (SBP). The reparative tissue was assessed using microfocus computed tomography and histology 3 months after implantation. RESULTS Regardless of the kind of bone substitutes, the defects were filled almost completely after implanting them at the level of the SBP, while the defects remained after implanting them at 2 or 4 mm below the SBP. Reparative tissue of the β-TCP75 group was similar to the normal cancellous bone, while that of the β-TCP67 or HA group was not. CONCLUSIONS Subchondral bone defects were filled almost completely only when bone substitutes were implanted at the level of the SBP. The reparative tissue after implanting the β-TCP bone substitutes with 75 % porosity was the most similar to the normal cancellous bone. Therefore, implanting the β-TCP bone substitutes with 75 % porosity at the level of the SBP could be recommended as a treatment method for subchondral bone repair in osteochondral defects.

Orthop Traumatol Surg Res 2015; 101:97-102. [PMID: 25599924 DOI: 10.1016/j.otsr.2014.11.006] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2014] [Revised: 11/05/2014] [Accepted: 11/21/2014] [Indexed: 02/02/2023]
Abstract
BACKGROUND The indications of osteochondral autograft implantation using the Mosaicplasty(®) technique were only recently extended to osteochondral lesions of the talus (OLT), a site for which no medium- or long-term outcome data are available. Our objective here was to evaluate medium-term outcomes in case-series of patients who underwent Mosaicplasty(®) for OLT repair. HYPOTHESIS Mosaicplasty(®) provides good medium-term outcomes with low morbidity when used for OLT repair. PATIENTS ET METHODS We retrospectively reviewed cases of Mosaicplasty(®) for OLT repair, performed in combination with malleolar osteotomy on the side of the OLT, at either of two centres, between 1997 and 2013. Pre-operative clinical data were collected from the medical records and all patients were re-evaluated. We studied 37 patients with a mean age of 33 years. RESULTS Mean follow-up at re-evaluation was 76 months. Mean AOFAS score at re-evaluation was 83 (range, 9-100). A work-related cause to the OLT was associated with significantly poorer outcomes (P=0.01). AOFAS values were significantly better in patients whose OLT size was 0.5 to 1cm(2). The Ogilvie-Harris score at last follow-up was good or excellent in 78% of patients. No patient experienced morbidity related to the malleolar osteotomy. Persistent patellar syndrome was noted in 6 patients. DISCUSSION In our case-series, Mosaicplasty(®) for OLT repair provided good medium-term outcomes in 78% of patients. Nevertheless, the donor-site morbidity should be borne in mind. Mosaicplasty(®) deserves to be viewed as a reference standard method for OLT repair. LEVEL OF EVIDENCE IV, retrospective study.

Abstract
BACKGROUND Advanced-stage osteochondritis dissecans of the capitellum affecting the lateral wall may result in osteoarthritis, and suitable treatment is needed to avoid permanent deformation and impaired function. We aimed to assess postoperative outcomes of costal osteochondral autograft for treatment of this condition. METHODS We included 22 young overhead athletes (mean age, 13.9 years) with advanced osteochondritis dissecans of the humeral capitellum who underwent costal osteochondral autograft. All patients had elbow pain and wide-range articular cartilage lesions. We evaluated clinical and radiographic outcomes at a mean follow-up of 27 months (range, 12-77 months). RESULTS All patients achieved rapid functional improvement and returned to their former sports activity levels. The baseball players were able to play catch within 62 to 164 days (mean, 107 days) and returned to full pitching activity within 123 to 339 days (mean, 226 days). We assessed mean elbow function by the clinical rating system of Timmerman and Andrews and the Japanese Orthopaedic Association sports score; the scores improved from 121.5 and 53.7 points preoperatively to 169.2 points and 86.1 points, respectively, at the time of follow-up. Four patients required additional minor surgical procedures, including screw removal, loose body removal, and shaving off of spur formation. No patient showed obvious radiographic changes of osteoarthritis. All patients were satisfied with the final outcomes and had good functional recovery. CONCLUSION Costal osteochondral autograft gave satisfactory results for advanced osteochondritis dissecans of the humeral capitellum with extensive lesions affecting the lateral wall.

Abstract
Posterior fracture dislocation of the femoral head is a rare entity usually requiring open reduction and internal fixation. Results of different fixation methods have been reported, including countersinking screws, headless screws, and bioabsorbable implants. Osteochondral autologous transfer (mosaicplasty) is an established method of treatment of full thickness cartilage defects of the knee, ankle, and elbow. At our institution, posterior fracture-dislocations of the femoral head were treated with femoral head fragment fixation using osteochondral autografts through surgical hip dislocation. Osteochondral plugs were harvested from the non-weight-bearing area of the lateral femoral condyle of the knee and used for fixation of the reduced fragment. This article details the technique and its application.

Abstract
BACKGROUND The treatment of osteochondral lesions of the talus after failed surgery is challenging, with no clear solution. Short-term results using autologous chondrocyte implantation have been promising. PURPOSE To report the long-term outcomes of patients who underwent autologous chondrocyte implantation (ACI) of the talus after failed marrow stimulation techniques for osteochondral lesions of the talus (OLTs). STUDY DESIGN Case series; Level of evidence, 4. METHODS Thirty-two consecutive patients underwent ACI of the talus, and 29 patients (15 male, 14 female; mean age, 34 years [range, 16-54 years]) were available for follow-up. There were 23 medial and 6 lateral lesions, with a mean size of 18 × 11 mm (198 mm(2); range, 80-500 mm(2)). Twenty patients underwent ACI of the talus alone; 9 underwent ACI with bone grafting of underlying cysts. Follow-up was performed at a mean of 70 months (range, 24-129 months). Patient outcomes were evaluated using the simplified symptomatology score, Tegner activity score, Finsen score, and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score. Twenty-five patients (86%) underwent second-look arthroscopic surgery at the time of hardware removal and were assessed with the International Cartilage Repair Society (ICRS) score. Postoperative magnetic resonance imaging (MRI) was performed on 24 patients (83%) and compared with preoperative MRI scans. RESULTS Preoperatively, 26 patients rated their ankles as poor and 3 as fair using the simplified symptomatology score. At last follow-up, 9 were classified as excellent, 14 as good, 5 as fair, and 1 as poor using the same score. The mean AOFAS score improved from 50.1 to 85.9 (range, 65-100). The mean Tegner activity score improved from 1.6 to 4.3 (P < .0001). The mean Finsen score (modified Weber score) showed significant improvement from 13.7 to 5.1 (P < .0001). CONCLUSION Autologous chondrocyte implantation of the talus yields improvement in all parameters tested with enduring long-term results in patients who have failed previous surgery for OLTs.

Abstract
Different techniques have been proposed for the treatment of cartilage defects. Among the currently available options, autologous single-plug osteochondral transplantation is one of the few to be applied to address small and medium lesions. The goal of the current study was to document the long-term clinical outcome of a cohort of patients treated by this surgical strategy, which consists of harvesting a single osteochondral plug from a less weight bearing area of the knee and implanting it on the defect site by press-fit technique. Fifteen patients were enrolled. Age at surgery was 30.2±15.3 years, and body mass index was 22.5±3.0 kg/m(2). The inclusion criteria were clinical symptoms, such as knee pain or swelling, and grade III to IV chondral and osteochondral knee lesions. Patients were prospectively evaluated up to a mean of 17.5±3.5 years of follow-up by using Lysholm, International Knee Documentation Committee (IKDC) subjective, and Tegner scores. A significant improvement was noted in all clinical scores. In particular, the IKDC subjective score increased from 34.5±23.6 to 66.3±26.4 (P=.001). The Lysholm score showed a similar trend. From a baseline value of 47.8±29.5, the score increased to 79.8±24.6 at the last evaluation (P=.001). A significant increase in Tegner score was observed at the 2-year evaluation, with stable results up to the last follow-up. Four failures were reported, which in 3 cases occurred at mid- to long-term follow-up, confirming that this technique can be considered a suitable option for the treatment of small and medium chondral and osteochondral lesions in young patients.

Abstract
In this article, we report using free vascularized medial femoral condyle (MFC) flaps for reconstruction of bone defects and nonunion of the hindfoot and ankle in two patients. One patient had an open calcaneal fracture and hindfoot bone defect with impaired gait due to Achilles tendon functional loss. The second patient had nonunion with a chondral defect of the talus after a fall. Following uneventful recoveries, good objective and subjective results were achieved in terms of pain reduction and improved gait in both patients. No further operative intervention was needed during a 3-year follow-up period. The versatility of the corticoperiosteal graft from the MFC makes it an important reconstructive tool for addressing several major surgical problems of bony nonunion in the extremities, including posttraumatic reconstruction of hindfoot and ankle disorders.

Osteochondral transplantation for the treatment of osteochondral defects at the talus with the Diamond twin system(®) and graft harvesting from the posterior femoral condyles.

Abstract
BACKGROUND The aim of this study is to analyze clinical results after osteochondral cylinder transplantation for osteochondral defects at the medial or lateral talar dome using the Diamond twin system (Karl Storz). We hypothesize that grafts harvesting from the posterior femoral condyles are associated with less donor site morbidity than reported by previous studies. METHODS We have surgically treated 20 patients with an osteochondral defect of the talus by osteochondral transplantation with the Diamond twin system via an osteotomy of the ankle. The osteochondral cylinders were harvested from the posterior aspects of the femoral condyles of the ipsilateral knee. The defects at donor site were filled with a bone substitute of tricalcium phosphate (Synthricer, Karl Storz). The mean age was 25.4 years. After a mean time of 12.6 months, the screws at the medial malleolus were removed and an arthroscopy was performed. The functional outcome was evaluated with the visual analog scale for pain at walking, running, stair climbing, quality of life at the time of implant removal and at a mean follow-up of 25.8 months. Activity was assessed with the Tegner scale. Knee function was evaluated with the Lysholm score. RESULTS In one case, the osteochondral cylinder did not heal and an osteochondral fragment was removed arthroscopically. In all other cases, the osteochondral cylinder was stable with surrounding cartilage. The average ICRS Cartilage Repair Assessment was 10.1 points (±1.3). All malleolar osteotomies healed radiologically. In 15 patients, a synovectomy and local debridement of the ankle were performed at second-look arthroscopy. Ankle pain at walking, running and stair climbing as measured by a visual analog scale (10-0) decreased significantly from preoperatively to the first follow-up (mean 12.6 months) and to the second follow-up (mean 25.8 months). The ankle-related quality of life increased significantly from preoperatively to postoperatively. There was no significant change in the Lysholm score. The activity measured with the Tegner activity scale increased significantly from preoperatively to the last follow-up, but only two out of nine patients continued pivoting sports. CONCLUSIONS Autologous osteochondral grafting with the Diamond twin system is a reliable treatment option for symptomatic osteochondral defects of the talus. After 1 year, the majority of patients had still some complaints. However, after screw removal and second-look arthroscopy, the pain and ankle-related quality of life further improved. CLINICAL RELEVANCE The donor site morbidity after graft harvesting from the posterior aspects of the femoral condyles is lower than previously reported.

Abstract
PURPOSE This study reports first evidence of a modified procedure for osteochondral autologous transplantation where bony periosteum-covered plugs are harvested at the iliac crest and transplanted into the talar osteochondral lesion. METHODS Thirteen out of 14 patients, average age 39.6 (SD 14.4) years, were followed clinically and radiographically for a median of 25 (24-28) months (minimal follow-up, 24 months). RESULTS For these 13 patients, the American Orthopaedic Foot and Ankle Society hindfoot score increased from 47 (SD 11) points pre-operatively, to 81 (SD 14) points postoperatively (p < 0.0001). The average pain score decreased from 6.6 (SD 1.3) points pre-operatively, to 1.4 (SD 1.9) points postoperatively (p < 0.0001). Seven patients returned to sports activity. Radiographically good plug osteointegration was observed in nine out of 11 ankles. Follow-up arthroscopy showed fibrous cartilage in four ankles, periosteum hypertrophy in five ankles, and partial or total missing of coverage of the bone in three ankles. Three revision surgeries had to be performed. CONCLUSIONS This modified mosaicplasty might be recommended for severe and recurrent osteochondral lesions of the talus and may lead to restoration of the subchondral bone stock, formation of fibro-cartilage, and stable joint function.

Abstract
PURPOSE The influence of basal graft support combined to early loading following an osteochondral autograft procedure is unclear. It was hypothesized that bottomed grafts may allow for early mobilization by preventing graft subsidence and leading to better healing. METHODS Osteochondral autografts were press fitted in the femoral condyles of 24 sheep (one graft per animal). In the unbottomed group (n = 12), a gap of 2 mm was created between graft and recipient bone base. In the bottomed group (n = 12), the graft firmly rested on recipient bone. Animals were allowed immediate postoperative weightbearing. Healing times were 3 and 6 months per group (n = 6 per subgroup). After killing, histological and histomorphometric analyses were performed. RESULTS Unbottomed grafts at 3 months showed significantly more graft subsidence (P = 0.024), significantly less mineralized bone (P = 0.028) and significantly worse cartilage and subchondral bone plate healing (P = 0.034) when compared to bottomed grafts. At 6 months, no differences were seen. Compared to the native situation, unbottomed grafts showed significantly more graft subsidence (P = 0.024), whereas bottomed grafts did not. Cystic lesions were seen in both groups. Osteoclasts were closely related to the degree of bone remodelling. CONCLUSION In the animal model, in the case of early loading, bottomed osteochondral autografts have less chance of graft subsidence. Evident subsidence negatively influences the histological healing process. In the osteochondral autograft procedure, full graft support should be aimed for. This may allow for early mobilization, diminish graft subsidence and improve long-term integration.

Abstract
Osteochondral lesions (OCLs) occur in up to 70% of sprains and fractures involving the ankle. Atraumatic aetiologies have also been described. Techniques such as microfracture, and replacement strategies such as autologous osteochondral transplantation, or autologous chondrocyte implantation are the major forms of surgical treatment. Current literature suggests that microfracture is indicated for lesions up to 15 mm in diameter, with replacement strategies indicated for larger or cystic lesions. Short- and medium-term results have been reported, where concerns over potential deterioration of fibrocartilage leads to a need for long-term evaluation. Biological augmentation may also be used in the treatment of OCLs, as they potentially enhance the biological environment for a natural healing response. Further research is required to establish the critical size of defect, beyond which replacement strategies should be used, as well as the most appropriate use of biological augmentation. This paper reviews the current evidence for surgical management and use of biological adjuncts for treatment of osteochondral lesions of the talus.

Abstract
PURPOSE Focal chondral and osteochondral knee lesions are a common condition, particularly hard to treat, and often involve young active patients with high expectations in terms of symptomatic relief and return to sports. Autologous osteochondral transplantation allows the defect area to be restored with hyaline cartilage. The aim of this study is to analyse whether it represents a safe and effective treatment option for small-medium-sized knee chondral and osteochondral lesions in a young and active population. METHODS Thirty-one patients (18 men, 13 women; mean age 32 ± ten; mean BMI 24 ± 3) affected by focal knee chondral and osteochondral lesions were enrolled and treated with autologous osteochondral transplantation. They were prospectively followed-up for 24 months with the IKDC-subjective, IKDC-objective, and Tegner scores. Adverse events and failures were also reported, as well as the Bandi score to detect symptoms from the donor area. RESULTS A significant increase was reported in all the clinical scores adopted. In particular, the IKDC-subjective score increased from a basal value of 40.3 ± 16.2 to 62.6 ± 18.0 at the 12 months' evaluation, with a further significant increase up to 71.6 ± 20.5 at the final 24 months' follow-up (p < 0.0005). A positive trend was also found by analysing the IKDC-objective score. The Tegner score revealed a significant improvement from a basal value of 2.2 ± 1.8 to 3.7 ± 1.5 at the final evaluation (p = 0.003), although it was not possible to regain the same pre-injury sports activity level of 5.0 ± 2.2. Two failures were reported. The Bandi score revealed patients complaining of mild and moderate symptoms, not correlated to the lesion size. The presence of symptoms ascribable to the donor area was significantly correlated with a lower clinical outcome. CONCLUSIONS Autologous osteochondral transplantation proved to be, at short-term evaluation, a suitable option to treat small-medium sized chondral and osteochondral lesions. However, clinical improvement is slow and a significant percentage of patients develop symptoms attributable to the donor area, thus reducing the overall benefit of this procedure.

Abstract
Osteochondritis dissecans affects the elbow of many young, skeletally immature athletes. The incidence of OCD in the elbow is second to its occurrence in the knee and similar to the incidence in the ankle. Young, athletically active individuals are at increased risk for developing this problem. There is a predilection for those involved in overhead-dominant sports and sports that require the arm to be a weight-bearing limb. The diagnosis is occurring earlier because of an increased awareness of the entity and the increased use of advanced imaging techniques, primarily magnetic resonance imaging. This earlier diagnosis has led to an increase in treatment ideas and modalities and ultimately improved care and outcomes.

Abstract
Tissue engineering and regenerative medicine (TERM) has caused a revolution in present and future trends of medicine and surgery. In different tissues, advanced TERM approaches bring new therapeutic possibilities in general population as well as in young patients and high-level athletes, improving restoration of biological functions and rehabilitation. The mainstream components required to obtain a functional regeneration of tissues may include biodegradable scaffolds, drugs or growth factors and different cell types (either autologous or heterologous) that can be cultured in bioreactor systems (in vitro) prior to implantation into the patient. Particularly in the ankle, which is subject to many different injuries (e.g. acute, chronic, traumatic and degenerative), there is still no definitive and feasible answer to ‘conventional’ methods. This review aims to provide current concepts of TERM applications to ankle injuries under preclinical and/or clinical research applied to skin, tendon, bone and cartilage problems. A particular attention has been given to biomaterial design and scaffold processing with potential use in osteochondral ankle lesions.

Abstract
Osteochondritis dissecans of the talus (ODT) describes a special entity of osteochondral lesions of the talus (OLT) which has to be distinguished from acute traumatic lesions. Its exact etiology still remains uncertain with multiple predispositioning factors being discussed. Following the knee and elbow, the ankle joint with 4% is the third most affected joint. Early stages can often be treated conservatively. In case of an advanced stage or failure of conservative treatment, a variety of operative techniques are available, which can be used based on the patient and the stage.

Abstract
The surgical management of young patients with large osteochondral lesions of the talus or end-stage osteoarthritis of the ankle joint presents a challenge to the orthopedic surgeon because these are well-recognized sources of pain and dysfunction. Procedures designed to address these disorders either have a limited role because of poor success rates or have significant implications, such as with the total ankle arthroplasty. Fresh osteochondral allografts allow defective tissue to be anatomically matched and reconstructed through transplantation. This article presents an overview of fresh osteochondral allografts, as well as potential concerns with their use, and summarizes the current literature.

Abstract
PURPOSE Osteochondral autologous transplantation (OAT) from the ipsilateral femoral lateral condyle in osteochondritis dissecans (OD) of the talus has shown good clinical results in the past. To further define, indications and limitations of OAT various factors have been discussed which might influence the clinical outcome. METHODS In this study, the clinical outcome of OAT of 32 patients (mean follow-up 29 months) was evaluated by means of the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale, ankle pain on the visual analogue scale (VAS), and Hospital for Special Surgery (HSS) Patella score. We then analysed the statistical correlation between clinical outcome and various variables such as age, pre-existing osteoarthritis, or size of the lesion. RESULTS Median AOFAS score was 86 (range 68-100), median ankle pain on VAS was 2.0 (range 0-5.5), and median HSS Patella score was 95 (range 35-100). Advanced age (above 40 years of age) was associated with a significantly lower HSS Patella score (80 vs. 97.5, p = 0.035). None of the other variables (obesity, pre-existing osteoarthritis, size of the lesion, necessity of malleolar osteotomy, localization of the lesion, and number of previous surgeries) influenced the clinical outcome adversely. CONCLUSIONS Osteochondral autologous transplantation in OD of the talus is a safe procedure with good clinical results. As advanced age is associated with higher donor-site morbidity, indication for OAT in older patients should be carefully considered. As none of the other variables affected the clinical outcome of OAT adversely, there is no contraindication for OAT, for example, in osteochondral lesions requiring more than one osteochondral grafts, lateral lesions, patients with BMI >25, pre-existing osteoarthritis, or failed previous surgery.

Abstract
➤ Osteochondral lesions of the talus are common injuries in recreational and professional athletes, with up to 50% of acute ankle sprains and fractures developing some form of chondral injury. Surgical treatment paradigms aim to restore the articular surface with a repair tissue similar to native cartilage and to provide long-term symptomatic relief.➤ Arthroscopic bone-marrow stimulation techniques, such as microfracture and drilling, perforate the subchondral plate with multiple openings to recruit mesenchymal stem cells from the underlying bone marrow to stimulate the differentiation of fibrocartilaginous repair tissue in the defect site. The ability of fibrocartilage to withstand mechanical loading and protect the subchondral bone over time is a concern.➤ Autologous osteochondral transplantation techniques replace the defect with a tubular unit of viable hyaline cartilage and bone from a donor site in the ipsilateral knee. In rare cases, a graft can also be harvested from the ipsilateral talus or contralateral knee. The limitations of donor site morbidity and the potential need for an osteotomy about the ankle should be considered. Some anterior or far posterior talar lesions can be accessed without arthrotomy or with a plafondplasty.➤ Osteochondral allograft transplantation allows an osteochondral lesion with a large surface area to be replaced with a single unit of viable articular cartilage and subchondral bone from a donor that is matched to size, shape, and surface curvature. The best available evidence suggests that this procedure should be limited to large-volume cystic lesions or salvage procedures.➤ Autologous chondrocyte implantation techniques require a two-stage procedure, the first for chondrocyte harvest and the second for implantation in a periosteum-covered or matrix-induced form after in vivo culture expansion. Theoretically, the transplantation of chondrocyte-like cells into the defect will result in hyaline-like repair tissue.
