Donor-recipient age- or sex-mismatched osteochondral allografts do not adversely affect cumulative graft survival rates after transplantation in the knee. Knee 2024; 51:35-43. [PMID: 39236636 DOI: 10.1016/j.knee.2024.08.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 07/15/2024] [Accepted: 08/09/2024] [Indexed: 09/07/2024]
Abstract
BACKGROUND Osteochondral allograft transplantation (OCAT) can be performed without the need for blood-type matching or anti-rejection medications. However, other donor-recipient mismatch variables could influence outcomes. Therefore, it is critical to examine the impacts of sex and age mismatching on functional OCA survival. METHODS Prospectively collected data for patients undergoing primary knee OCAT enrolled in a lifelong outcomes registry were analyzed for functional OCA survival based on sex- and age-matched and -mismatched cohorts. Treatment failure was defined as the need for OCAT revision surgery or knee arthroplasty. RESULTS 162 donor-recipient pairs were analyzed; 57 (35.2%) were sex-mismatched and 89 (54.9%) were age-mismatched. Sex-mismatched OCATs were not associated with a significantly different cumulative graft survival rate when compared to sex-matched OCATs (78.9% vs 75.2% p = 0.324). Age-mismatched OCATs were not associated with a significantly different cumulative graft survival rate when compared to age-matched OCATs (71.6% vs 81.5% p = 0.398). When adjusting for sex, BMI, concomitant procedures, and surgery type, age-mismatched and sex-mismatched OCATs were not significantly associated with higher likelihood for treatment failure. CONCLUSION By analyzing functional graft survival rates for donor-recipient sex- or age-mismatched OCAs following primary OCAT, the results of the present study support current donor-recipient matching protocols for OCA transplantation in the knee. Based on current evidence, donor-recipient blood-type, sex-, and age-matching are not required for safe and effective primary OCAT in the knee. However, further studies are imperative for defining modifiable variables that further optimize safety and outcomes while maximizing donor tissue quality, availability, access, and use.

Rev Esp Cir Ortop Traumatol (Engl Ed) 2024; 68:T490-T496. [PMID: 38971565 DOI: 10.1016/j.recot.2024.01.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 12/28/2023] [Accepted: 01/11/2024] [Indexed: 07/08/2024] Open
Abstract
BACKGROUND Previous research using osteochondral autograft transfer (OAT) has shown poorer outcomes with increasing patient age. The aim of this article is to evaluate a cohort of patients that received an OAT and to correlate their clinical results with their age at procedure. METHODS Patients that underwent an OAT to treat an osteochondral (OC) lesion with a minimum 24-month follow-up were included. Patients were categorized into two groups based on their age at procedure (<40 years and ≥40 years). Postoperatively, each patient completed the Knee injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC), and Lysholm scales. RESULTS 51 patients were included (35<40 years, 16≥40 years). Mean follow-up was 4.2 years (2-7). For patients<40 years, IKDC averaged 80.8 (SD 15.9) versus 71.2 (SD 19.4) in ≥40 years (p=0.03). For patients <40 years, Lysholm averaged 85.9 (SD 10.8) versus 77.0 (SD 21.6) in ≥40 years (p=0.02). For patients<40 years, KOOS averaged 78.3 (SD 11.8) versus 68.9 (SD 18.5) in ≥40 years (p=0.01). There was a 100% sensibility in identifying all the patients with a poor IKDC and Lysholm from 34 years old (AUC 0.76 and 0.8). CONCLUSIONS OAT has better outcomes in patients younger than 40 years compared to patients older than 40 years. Based on the prognostic capacity of age, the ideal candidate for an OAT is a patient younger than 34 years old.

Abstract
OBJECTIVE Osteochondral allograft (OCA) transplantation is a restorative surgical option for large, full-thickness chondral or osteochondral defects in the knee. Variability in outcomes reporting has led to a broad range of graft survival rates. Using rate of salvage surgery following OCA as a failure metric, the purpose of this study was to analyze the incidence and risk factors for failure in a nationwide cohort. DESIGN The M151Ortho PearlDiver database was queried for patients aged 20 to 59 who underwent primary OCA between 2010 and 2020. Patients with prior cartilage procedures or arthroplasty were excluded. Kaplan-Meier survival analysis was performed to characterize cumulative rate of salvage surgery, defined as any patient subsequently undergoing revision OCA, autologous chondrocyte implantation (ACI), osteochondral autograft transfer system (OATS), unicompartmental knee arthroplasty (UKA), or total knee arthroplasty (TKA). Multivariable logistic regression was used to determine the effect of several variables on odds of salvage surgery. RESULTS Around 6,391 patients met inclusion criteria. Cumulative 5-year salvage rate was 1.71%, with 68.8% in the first 2 years. Age 20 to 29 and concomitant or prior bony realignment procedures were associated with significantly decreased rate of salvage surgery (age-adjusted odds ratio [aOR] = 0.49, 95% confidence interval [CI], 0.24-0.99, P = 0.046; realignment-aOR = 0.24, 95% CI, 0.04-0.75, P = 0.046). CONCLUSIONS In the largest OCA cohort studied to date, less than 2% of patients required salvage surgery. Young age and bony realignment were protective. These findings suggest that OCA in the knee is a durable cartilage-restoration procedure, especially in young patients with corrected alignment.

Abstract
BACKGROUND Treatment of large articular cartilage lesions of the knee includes surgical options one of which includes cartilage replacement therapies. Among these therapies include osteochondral allograft (OCA) transplantation, which can be performed utilizing a BioUni® (Arthrex BioUni® Instrumentation System; Arthrex, Naples, FL) replacement and a 'snowman' technique of repair. HYPOTHESIS/PURPOSE To compare clinical and radiographic outcomes in patients who have undergone multiplug OCA transplantations utilizing a BioUni® replacement and a 'snowman' technique of repair. METHODS Patients who underwent OCA transplantation utilizing a snowman technique or BioUni® replacement between January 1st, 2012 and December 31st, 2018, and who had a minimum 1-year follow-up at the same institution were identified for inclusion in this study via current procedural terminology (CPT) codes. Charts of included patients were reviewed for injury and treatment details as well as demographic information. Imaging studies and operative reports were reviewed and pre and postoperative subjective and objective outcome measures were recorded. RESULTS Twenty-eight patients underwent OCA transplantation with either BioUni® replacement (n=5) or with snowman technique repair (n=23). Defects in both groups had similar characteristics including size, area, location, and classifications. Patient-reported outcomes using the Knee Injury and Osteoarthritis Outcome Score-Joint Replacement (KOOS-JR), International Knee Documentation Committee (IKDC), and Physical Health Composite Score (PCS-12) were similar at baseline and increased post-operatively for both groups with no significant differences between techniques after a mean follow-up of 2.77 ± 0.83. Although it did not reach significance, the snowman group had higher rates of knee-related complications (13%) and need for revision surgery (22%) when compared to BioUni® (0% and 0%, respectively). CONCLUSION The use of both BioUni® and snowman techniques for large, unicondylar articular cartilage lesions of the femoral condyle demonstrate improved patient-reported outcomes at short-term follow-up. The use of the snowman technique presents relatively higher rates of revision similar to previous studies with no statistical difference in patient-reported outcomes when compared to those of a single plug OCA using a BioUni® system.

Abstract
Background Osteochondral allograft transplantation (OCA) treats symptomatic focal cartilage defects with satisfactory clinical results. Purpose To comprehensively analyze the characteristics and clinical outcomes of OCA for treating articular cartilage defects. Study Design Systematic review; Level of evidence, 4. Methods We searched Embase, PubMed, Cochrane Database, and Web of Science for studies published between January 1, 2001, and December 31, 2020, on OCA for treating articular cartilage defects. Publication information, patient data, osteochondral allograft storage details, and clinical outcomes were extracted to conduct a comprehensive summative analysis. Results In total, 105 studies involving 5952 patients were included. The annual reported number of patients treated with OCA increased from 69 in 2001 to 1065 in 2020, peaking at 1504 cases in 2018. Most studies (90.1%) were performed in the United States. The mean age at surgery was 34.2 years, and 60.8% of patients were male and had a mean body mass index of 26.7 kg/m2. The mean lesion area was 5.05 cm2, the mean follow-up duration was 54.39 months, the mean graft size was 6.85 cm2, and the number of grafts per patient was 54.7. The failure rate after OCA was 18.8%, and 83.1% of patients reported satisfactory results. Allograft survival rates at 2, 5, 10, 15, 20, and 25 years were 94%, 87.9%, 80%, 73%, 55%, and 59.4%, respectively. OCA was mainly performed on the knee (88.9%). The most common diagnosis in the knee was osteochondritis dissecans (37.9%), and the most common defect location was the medial femoral condyle (52%). The most common concomitant procedures were high tibial osteotomy (28.4%) and meniscal allograft transplantation (24.7%). After OCA failure, 54.7% of patients underwent revision with primary total knee arthroplasty. Conclusion The annual reported number of patients who underwent OCA showed a significant upward trend, especially from 2016 to 2020. Patients receiving OCA were predominantly young male adults with a high body mass index. OCA was more established for knee cartilage than an injury at other sites, and its best indication was osteochondritis dissecans. This analysis demonstrated satisfactory long-term postoperative outcomes.

Abstract
Background Preoperative magnetic resonance imaging (MRI) is used to estimate the quantity of tissue provided for fresh osteochondral allograft (FOCA) in the knee. Use of 3-dimensional (3D) MRI modeling software for this purpose may improve defect assessment, providing a more accurate estimate of osteochondral allograft tissue required and eliminating the possibility of acquiring an inadequate quantity of tissue for transplant surgery. Purpose To evaluate the capacity of damage assessment (DA) 3D MRI modeling software to preoperatively estimate the osteochondral allograft surface area used in surgery. Study Design Cohort study (diagnosis); Level of evidence, 2. Methods Included were 36 patients who had undergone FOCA surgery to the distal femur. Based on the preoperative MRI scans, the DA software estimated the total surface area of the lesion as well as the surface areas of each subarea of injury: full-thickness cartilage injury (International Cartilage Repair Society [ICRS] grade 4), partial-thickness cartilage injury (ICRS grade 2-3), bone marrow edema, bone loss, and bone cyst. The probability of overestimation of graft tissue areas by the DA software was calculated using a Bayes-moderated proportion, and the relationship between the prediction discrepancy (ie, over- or underestimation) and the magnitude of the DA estimate was assessed using nonparametric local-linear regression. Results The DA total surface area measurement overestimated the actual area of FOCA tissue transplanted 81.6% (95% CI, 67.2%-91.4%) of the time, corresponding to a median overestimation of 3.14 cm2, or 1.78 times the area of FOCA transplanted. The DA software overestimated the area of FOCA transplanted 100% of the time for defect areas measuring >4.52 cm2. For defects <4.21 cm2, the maximum-magnitude underestimation of tissue area was 1.45 cm2 (on a fold scale, 0.63 times the transplanted area); a plausible heuristic is that multiplying small DA-measured areas of injury by a factor of ∼1.5 would yield an overestimation of the tissue area transplanted most of the time. Conclusion The DA 3D modeling software overestimated osteochondral defect size >80% of the time in 36 distal femoral FOCA cases. A policy of consistent but limited overestimation of osteochondral defect size may provide a more reliable basis for predicting the minimum safe amount of allograft tissue to acquire for transplantation.

Abstract
Purpose To define the criteria for coverage for a cartilage restoration procedure and osteochondral allograft (OCA) transplantation and to investigate coverage for OCA procedures among private payer medical policies. Methods A systematic search of private payer websites was conducted to identify publicly available 2018 OCA medical policies. Medical criteria related to patient demographics, defect characteristics, and previous treatment were analyzed. Trends in coverage for treatment of talus and patella and the extent of restrictiveness of medical policies were evaluated from 2016 to 2018. The extent of restrictiveness of a policy was defined by number of medical criteria established by payer policies. Policies with >5, 3-5, and <3 specified criteria for OCAs were considered strongly, moderately, and weakly restrictive, respectively. Results In total, 49 private payer medical policies for OCA transplantation were identified. Extracted criteria varied greatly between medical policies. Ten different defect size ranges were reported across payer policies. Criteria for patient body mass index was specified in 63% of policies. Criteria for failed arthroscopic or traditional surgical procedure were identified in 20% of the policies. More than one half of policies (51%) specified knee defect location to load-bearing surfaces. Analysis of trends in positive coverage statements and restrictiveness showed an increase from 4.7% in 2016 to 39.5% for talus, 4.7% to 7.0% for patella, and a slight shift (4.7% of payers) toward weakly restrictive medical policies. Conclusions This study demonstrates wide variability and inconsistencies in published criteria among OCA medical policies. Clinical Relevance This study informs clinicians of the current state of coverage for OCA transplantation, providing insights into the variability of payer policies and potential impact.

Abstract
BACKGROUND Although osteochondral allograft (OCA) transplantation has been a standard treatment for patients with osteochondral lesions, there is a disagreement in commercial payers' medical criteria regarding the definition of medical suitability and thus authorization for OCA transplantation. The primary goal of this study was to understand where consensus between a committee of experienced cartilage restoration surgeon scientists and payer policies existed and where there was significant disagreement. METHODS U.S. private payers were identified by reviewing health insurance market research literature. Medical criteria were then obtained from publicly available payer medical polices. A literature review was conducted to identify supporting evidence for consensus statements based on private payer medical criteria. The MOCA (Metrics of Osteochondral Allograft) Committee, 30 experienced surgeons and subject-matter experts in OCA transplantation, used a Likert scale of 1 (strongly disagree) to 5 (strongly agree) to rank each statement. The extent of agreement and disagreement among participants was measured for each statement. Consensus was defined as agreement or disagreement of >75%. RESULTS Fifty-seven statements regarding relevant medical criteria for OCA transplantation were included in the survey. All 30 MOCA Committee members completed the survey (100% response rate). Over half of the statements (52.6%) did not reach consensus. Of the remaining 27 statements that reached consensus, respondents agreed or strongly agreed with 16 statements, and disagreed or strongly disagreed with 11 statements. Inconsistent voting was observed for statements related to osteoarthritis, inflammation, and degenerative changes. CONCLUSIONS Commercial payers are not consistent in the medical criteria used to define patient eligibility for authorization of OCA transplantation. In contrast, an expert panel of cartilage surgeons reached a consensus that OCA transplantation was clearly suitable for a variety of specific indications. This study demonstrates the need to standardize medical criteria for cartilage restoration based on the most current literature, as well as in conjunction with experienced cartilage restoration experts.

Abstract
Knee articular cartilage defects can result in significant pain and loss of function in active patients. Osteochondral allograft (OCA) transplantation offers a single-stage solution to address large chondral and osteochondral defects by resurfacing focal cartilage defects with mature hyaline cartilage. To date, OCA transplantation of the knee has demonstrated excellent clinical outcomes and long-term survivorship. However, significant variability still exists among clinicians with regard to parameters for graft acceptance, surgical technique, and rehabilitation. Technologies to optimize graft viability during storage, improve osseous integration of the allograft, and shorten recovery timelines after surgery continue to evolve. The purpose of this review is to examine the latest evidence on treatment indications, graft storage and surgical technique, patient outcomes and survivorship, and rehabilitation after surgery.

Abstract
BACKGROUND Multiple cartilage repair techniques are available for chondral defects in the knee. Optimal treatment is controversial. PURPOSE To evaluate change from baseline in the 5 Knee injury and Osteoarthritis Outcome Score (KOOS) subscales among different cartilage repair techniques of the knee. STUDY DESIGN Systematic review and meta-analysis; Level of evidence, 1A. METHODS Medline and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched for randomized controlled trials with minimum 1 year follow-up reporting change from baseline KOOS (delta KOOS) subscale values. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed. A meta-analysis was performed on the following surgery types: microfracture (Mfx); augmented microfracture techniques (Mfx+Augment); and culture-based therapies, including autologous chondrocyte implantation (ACI) and matrix-assisted autologous chondrocyte implantation (MACI). A random-effects metaregression model was used. RESULTS A total of 14 randomized trials with a total of 775 patients were included. The KOOS Sport and Recreation (Sport) and KOOS Quality of Life (QOL) were the 2 most responsive subscales after operative intervention. Outcomes from Mfx and Mfx+Augment were not different in any of the 5 KOOS subscales (minimum P > .3). The mean delta KOOS Sport after ACI/MACI was 9.9 points greater than after Mfx (P = .021) and 11.7 points greater than after Mfx+Augment (P = .027). Longer follow-up time correlated with greater delta KOOS Sport (P = .028). Larger body mass index led to greater delta KOOS QOL (P = .045). Larger cartilage defect size correlated with greater delta KOOS Pain and KOOS Activities of Daily Living scores (P = .023 and P = .002, respectively). CONCLUSION The KOOS Sport and QOL were the most responsive subscales after cartilage restoration surgery of the knee. Culture-based therapies (ACI/MACI) led to clinically relevant improvements in the KOOS Sport score compared with marrow stimulation and may be a more appropriate treatment in younger and more active individuals. There were no benefits to Mfx+Augment over Mfx alone in any of the KOOS subscales.

Abstract
BACKGROUND Sex mismatch between donor and recipient has been considered a potential contributor to adverse outcomes after solid organ transplantation. However, the influence of sex mismatching in osteochondral allograft (OCA) transplantation has yet to be determined. PURPOSE To evaluate whether donor-recipient sex mismatching affects graft survival after OCA transplantation. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS In this review of prospectively collected data, patients who underwent OCA transplantation between November 2013 and November 2017 by a single surgeon were analyzed. Cumulative survival was assessed via the Kaplan-Meier method using log-rank tests to compare patients with similar donor groups. Multivariable Cox regression analysis adjusted for patient age, graft size, and body mass index was used to evaluate the influence of donor-recipient sex on graft survival. RESULTS A total of 154 patients were included: 102 (66.2%) who received OCAs from a same-sex donor and 52 (33.8%) who received OCAs from a different-sex donor. At 5-year follow-up, a significantly lower graft survival rate was observed for different-sex donor transplantation in comparison with same-sex donorship (63% vs 92%; P = .01). When correcting for age, graft size, and body mass index, donor-recipient sex-mismatch transplantation demonstrated a 2.9-times greater likelihood to fail at 5 years compared with donor-recipient same-sex transplantation (95% CI, 1.11-7.44; P = .03). A subgroup analysis showed no significant difference in graft survival between the female-to-female and female-to-male groups (91% and 84%, respectively). Conversely, male-to-male transplantation demonstrated a significantly higher cumulative 5-year survival (94%; P = .04), whereas lower survival was found with male-to-female donorship (64%; P = .04). Multivariable Cox regression indicated a 2.6-times higher likelihood of failure for the male-to-female group in comparison with the other groups (95% CI, 1.03-6.69; P = .04). Male-to-male transplantation had a tendency toward decreased likelihood of OCA failure (hazard ratio, 0.33), although without statistical significance (95% CI, 0.11-1.01; P = .052). CONCLUSION Mismatch between donor and recipient sex had a negative effect on OCA survival after transplantation, particularly in those cases when male donor tissue was transplanted into a female recipient.

Abstract
OBJECTIVE The purpose of this study was to evaluate the efficacy of osteochondral allograft (OCA) in patients older than 45 years of age, particularly with respect to return to sport. DESIGN A retrospective review was performed to evaluate patients greater than 45 who underwent an OCA for a symptomatic osteochondral defect of the knee between June 2011 and January 2019. RESULTS Overall, there were 18 patients (76% male) that met our inclusion and exclusion criteria. Follow-up was attained in 14 of these patients (78%). The mean age of patients included was 52.6 years (48-57) with a mean of 37 months of follow-up (18-60). Visual Analogue Scale scores decreased significantly from the preoperative baseline to final follow-up (7.7 ± 1.7 vs. 2.0 ± 2.0, P < 0.01). Furthermore, the mean Visual Analogue Scale while playing sport was 3.4 ± 3.2, and the mean Knee Injury and Osteoarthritis Outcome Score was 77.5 ± 12.7 at final follow-up. Overall, 11 patients (78.6%) were able to return to their desired sport. No clinical failures were identified during the follow-up period. CONCLUSION In our series of patients 45 years and older who were treated with OCA for focal osteochondral injuries of the knee, we found a significant improvement in clinical outcome scores at a midterm follow-up of 37 months with no revision OCA procedures or conversion to any form of knee arthroplasty. In addition, a high percentage of patients were able to return to their preferred level of athletic activity.

Orthop J Sports Med 2021; 9:23259671211031244. [PMID: 34676269 PMCID: PMC8524698 DOI: 10.1177/23259671211031244] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Accepted: 03/22/2021] [Indexed: 01/08/2023] Open
Abstract
Background: Focal cartilage defects are often debilitating, possess limited potential for
regeneration, are associated with increased risk of osteoarthritis, and are
predictive for total knee arthroplasty. Cartilage repair studies typically
focus on the outcome in younger patients, but a high proportion of treated
patients are 40 to 60 years of age (ie, middle-aged). The reality of current
clinical practice is that the ideal patient for cartilage repair is not the
typical patient. Specific attention to cartilage repair outcomes in
middle-aged patients is warranted. Purpose: To systematically review available literature on knee cartilage repair in
middle-aged patients and include studies comparing results across different
age groups. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic search was performed in EMBASE, MEDLINE, and the Cochrane
Library database. Articles were screened for relevance and appraised for
quality. Results: A total of 21 articles (mean Coleman Methodology Score, 64 points) were
included. Two out of 3 bone marrow stimulation (BMS) studies, including 1
using the microfracture technique, revealed inferior clinical outcomes in
middle-aged patients in comparison with younger patients. Nine cell-based
studies were included showing inconsistent comparisons of results across age
groups for autologous chondrocyte implantation (ACI). Bone marrow aspirate
concentrate showed age-independent results at up to 8 years of follow-up. A
negative effect of middle age was reported in 1 study for both ACI and BMS.
Four out of 5 studies on bone-based resurfacing therapies (allografting and
focal knee resurfacing implants [FKRIs]) showed age-independent results up
to 5 years. One study in only middle-aged patients reported better clinical
outcomes for FKRIs when compared with biological repairs. Conclusion: Included studies were heterogeneous and had low methodological quality. BMS
in middle-aged patients seems to only result in short-term improvements.
More research is warranted to elucidate the ameliorating effects of
cell-based therapies on the aging joint homeostasis. Bone-based therapies
seem to be relatively insensitive to aging and may potentially result in
effective joint preservation. Age subanalyses in cohort studies, randomized
clinical trials, and international registries should generate more evidence
for the large but underrepresented (in terms of cartilage repair)
middle-aged population in the literature.

Abstract
BACKGROUND Studies have reported favorable clinical outcomes after osteochondral allograft (OCA) transplantation to treat osteochondral defects and have demonstrated that healing of the osseous component may be critical to outcomes. However, there is currently no consensus on the optimal modality to evaluate osseous healing. PURPOSE To define parameters for OCA healing using computed tomography (CT) and to investigate whether osseous healing identified using CT is correlated with improved pain and function on patient-reported outcomes (PROs) collected closest in time to the postoperative CT scan and at final follow-up. STUDY DESIGN Case series; Level of evidence, 4. METHODS Of 118 patients who underwent OCA transplantation for articular cartilage defects of the knee over the 10-year study period, 60 were included in final analysis based on completion of CT scans at 5.8 ± 1.9 months postoperatively and PROs collected preoperatively and postoperatively. CT parameters, including osseous incorporation, bone density, subchondral bone congruency, and cystic changes, were summarized for each patient relative to the cohort. Parameters were assessed for inter- and intrarater reliability as well as for covariation with patient characteristics and surgical variables. Structural equation modeling was used to assess correlation of CT parameters with change in PROs from preoperatively to those collected closest in time to CT acquisition and at the final follow-up. RESULTS Bone incorporation was the most reliable CT parameter. The summarized scores for CT scans were normally distributed across the study population. Variance in CT parameters was independent of age, sex, body mass index, prior surgery, number of grafts, lesion size, and location. No significant correlation (P > .12 across all comparisons) was identified for any combination of CT parameter and change in PROs from baseline for outcomes collected either closest to CT acquisition or at the final follow-up (mean, 38.2 ± 19.9 months; range, 11.6-84.9 months). There was a uniformly positive association between change in PROs and host bone density but not graft bone density, independent of patient characteristics and surgical factors. CONCLUSION CT parameters were independent of clinical or patient variables within the study population, and osseous incorporation was the most reliable CT parameter. Metrics collected from a single postoperative CT scan was not correlated with clinical outcomes at ≥6-month longitudinal follow-up.

[PMID: 34377714 PMCID: PMC8320585 DOI: 10.1177/23259671211017135] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Accepted: 02/15/2021] [Indexed: 12/20/2022] Open
Abstract
Background: Fresh osteochondral allograft (OCA) is a treatment option that allows for the transfer of size-matched allograft cartilage and subchondral bone into articular defects of the knee. Although long-term studies show good functional improvement with OCA, there continues to be wide variability and a lack of consensus in terms of postoperative rehabilitation protocols and return to sport. Purpose: To systematically review the literature and evaluate the reported rehabilitation protocols after OCA of the knee, including weightbearing and range of motion (ROM) restrictions as well as return-to-play criteria. Study Design: Systematic review; Level of evidence, 4. Methods: PubMed, EMBASE, Cumulative Index of Nursing Allied Health Literature, SPORTDiscus, and Cochrane databases were searched according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for studies on knee OCA. Studies were included if they reported return-to-play data or postsurgical rehabilitation protocols. Results: A total of 62 studies met the inclusion criteria, with a total of 3451 knees in 3355 patients. Concomitant procedures were included in 30 of these studies (48.4%). The most commonly cited rehabilitation protocols included weightbearing restrictions and ROM guidelines in 100% and 90% of studies, respectively. ROM was most commonly initiated within the first postoperative week, with approximately half of studies utilizing continuous passive motion. Progression to weightbearing as tolerated was reported in 60 studies, most commonly at 6 weeks (range, immediately postoperatively to up to 1 year). Of the 62 studies, 37 (59.7%) included an expected timeline for either return to play or return to full activity, most commonly at 6 months (range, 4 months to 1 year). Overall, 13 studies (21.0%) included either objective or subjective criteria to determine return to activity within their rehabilitation protocol. Conclusion: There is significant heterogeneity for postoperative rehabilitation guidelines and the return-to-play protocol after OCA of the knee in the literature, as nearly half of the included studies reported use of concomitant procedures. However, current protocols appear to be predominantly time-based without objective criteria or functional assessment. Therefore, the authors recommend the development of objective criteria for patient rehabilitation and return-to-play protocols after OCA of the knee.

Abstract
Background: Osteochondral allograft (OCA) transplantation has evolved into a first-line
treatment for large chondral and osteochondral defects, aided by
advancements in storage protocols and a growing body of clinical evidence
supporting successful clinical outcomes and long-term survivorship. Despite
the body of literature supporting OCAs, there still remains controversy and
debate in the surgical application of OCA, especially where high-level
evidence is lacking. Purpose: To develop consensus among an expert group with extensive clinical and
scientific experience in OCA, addressing controversies in the treatment of
chondral and osteochondral defects with OCA transplantation. Study Design: Consensus statement. Methods: A focus group of clinical experts on OCA cartilage restoration participated
in a 3-round modified Delphi process to generate a list of statements and
establish consensus. Questions and statements were initially developed on
specific topics that lack scientific evidence and lead to debate and
controversy in the clinical community. In-person discussion occurred where
statements were not agreed on after 2 rounds of voting. After final voting,
the percentage of agreement and level of consensus were characterized. A
systematic literature review was performed, and the level of evidence and
grade were established for each statement. Results: Seventeen statements spanning surgical technique, graft matching,
indications, and rehabilitation reached consensus after the final round of
voting. Of the 17 statements that reached consensus, 11 received unanimous
(100%) agreement, and 6 received strong (80%-99%) agreement. Conclusion: The outcomes of this study led to the establishment of consensus statements
that provide guidance on surgical and perioperative management of OCAs. The
findings also provided insights on topics requiring more research or
high-quality studies to further establish consensus and provide stronger
evidence.

Duan WP, Huang LA, Dong ZQ, Li HQ, Guo L, Song WJ, Yang YF, Li PC, Wei XC. Studies of Articular Cartilage Repair from 2009 to 2018: A Bibliometric Analysis of Articles. Orthop Surg 2021; 13:608-615. [PMID: 33554478 PMCID: PMC7957388 DOI: 10.1111/os.12888] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2020] [Revised: 11/08/2020] [Accepted: 11/16/2020] [Indexed: 01/20/2023] Open
Abstract
Objective To perform a bibliometric analysis of research on articular cartilage repair published in Chinese and English over the past decade. Fundamental and clinical research topics of high interest were further comparatively analyzed. Methods Relevant studies published from 1 January 2009 to 31 December 2018 (10 years) were retrieved from the Wanfang database (Chinese articles) and six databases, including MEDLINE, WOS, INSPEC, SCIELO, KJD, and RSCI on the website “Web of Science” (English articles), using key words: “articular cartilage” AND “injury” AND “repair”. The articles were categorized according to research focuses for a comparative analysis between those published in Chinese vs English, and further grouped according to publication date (before and after 2014). A comparative analysis was performed on research focus to characterize the variation in research trends between two 5‐year time spans. Moreover, articles were classified as basic and clinical research studies. Results Overall, 5762 articles were retrieved, including 2748 in domestic Chinese journals and 3014 in international English journals. A total of 4937 articles focused on the top 10 research topics, with the top 3 being stem cells (32.1%), tissue‐engineered scaffold (22.8%), and molecular mechanisms (16.4%). Differences between the numbers of Chinese and English papers were observed for 3 topics: chondrocyte implantation (104 vs 316), osteochondral allograft (27 vs 86), and microfracture (127 vs 293). The following topics gained more research interest in the second 5‐year time span compared with the first: microfracture, osteochondral allograft, osteochondral autograft, stem cells, and tissue‐engineered scaffold. Articles with a focus on three‐dimensional‐printing technology have shown the fastest increase in publication numbers. Among 5613 research articles, basic research studies accounted for the majority (4429), with clinical studies described in only 1184 articles. The top 7 research topics of clinical studies were: chondrocyte implantation (28.7%), stem cells (21.9%), microfracture (19.2%), tissue scaffold (10.6%), osteochondral autograft (10.5%), osteochondral allograft (6.3%), and periosteal transplantation (2.8%). Conclusion Studies focused on stem cells and tissue‐engineered scaffolds led the field of damaged articular cartilage repair. International researchers studied allograft‐related implantation approaches more often than Chinese researchers. Traditional surgical techniques, such as microfracture and osteochondral transplantation, gained high research interest over the past decade.

In vitro and in vivo study on the osseointegration of BCP-coated versus uncoated nondegradable thermoplastic polyurethane focal knee resurfacing implants. J Biomed Mater Res B Appl Biomater 2020; 108:3370-3382. [PMID: 32614486 PMCID: PMC7586808 DOI: 10.1002/jbm.b.34672] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2019] [Revised: 04/18/2020] [Accepted: 06/03/2020] [Indexed: 11/10/2022]
Abstract
Focal knee resurfacing implants (FKRIs) are intended to treat cartilage defects in middle-aged patients. Most FKRIs are metal-based, which hampers follow-up of the joint using magnetic resonance imaging and potentially leads to damage of the opposing cartilage. The purpose of this study was to develop a nondegradable thermoplastic polyurethane (TPU) FKRI and investigate its osseointegration. Different surface roughness modifications and biphasic calcium phosphate (BCP) coating densities were first tested in vitro on TPU discs. The in vivo osseointegration of BCP-coated TPU implants was subsequently compared to uncoated TPU implants and the titanium bottom layer of metal control implants in a caprine model. Implants were implanted bilaterally in stifle joints and animals were followed for 12 weeks, after which the bone-to-implant contact area (BIC) was assessed. Additionally, 18F-sodium-fluoride (18F-NaF) positron emission tomography PET/CT-scans were obtained at 3 and 12 weeks to visualize the bone metabolism over time. The BIC was significantly higher for the BCP-coated TPU implants compared to the uncoated TPU implants (p = .03), and did not significantly differ from titanium (p = .68). Similar 18F-NaF tracer uptake patterns were observed between 3 and 12 weeks for the BCP-coated TPU and titanium implants, but not for the uncoated implants. TPU FKRIs with surface modifications could provide the answer to the drawbacks of metal FKRIs.
