Abstract
Background The etiology and pathogenesis of osteochondritis dissecans (OCDs) lesions remain controversial. Methods This review presents the recent evolution about the healing, imaging, pathogenesis, and how to treat OCD of the capitellum in overhead athletes. Results Compressive and shear forces to the growing capitellum can cause subchondral separation, leading to OCD, composed of 3 layers: articular fragment, gap, and underlying bone. Subchondral separation can cause ossification arrest (stage IA), followed by cartilage degeneration (stage IB) or delayed ossification (stage IIA), occasionally leading to osteonecrosis (stage IIB) in the articular fragment. Articular cartilage fracture and gap reseparation make the articular fragment unstable. The mean tilting angle of capitellar OCD is 57.6 degrees in throwers. Anteroposterior radiography of the elbow at 45 degrees of flexion (APR45) can increase the diagnostic reliability, showing OCD healing stages, as follows: I) radiolucency, II) delayed ossification, and III) union. Coronal computed tomography and magnetic resonance imaging with an appropriate tilting angle can also increase the reliability. MRI is most useful to show the instability, although it occasionally underestimates. Sonography contributes to detection of early OCD in adolescent throwers on the field. OCD lesions in the central aspect of the capitellum can be more unstable and may not heal. Cast immobilization has a positive effect on healing for stable lesions. Arthroscopic removal provides early return to sports, although a large osteochondral defect is associated with a poor prognosis. Fragment fixation, osteochondral autograft transplantation, and their hybrid technique have provided better results. Discussion Further studies are needed to prevent problematic complications of capitellar OCD, such as osteoarthritis and chondrolysis.

Abstract
Osteochondritis dissecans (OCD) of the elbow mainly occurs in overhead athletes (OHAs). This narrative review aimed to comprehensively analyze the epidemiological data, etiological factors, clinical and imaging features, treatment options, and outcomes of OHAs with the diagnosis of elbow OCD. A literature search was performed in PubMed/MEDLINE, Scopus, and Web of Science. Individuals with elbow OCD were usually 10-17 years of age with incidence and prevalence varying between studies, depending on the sport activity of the patients. The etiology of OCD lesions is multifactorial, and the main causes are believed to be repetitive trauma, the biomechanical disproportion of the articular surfaces, poor capitellar vascular supply, and inflammatory and genetic factors. Athletes usually presented with elbow pain and mechanical symptoms. The mainstay for the diagnosis of elbow OCD is MRI. The treatment of elbow OCD lesions should be conservative in cases of stable lesions, while various types of surgical treatment are suggested in unstable lesions, depending mainly on the size and localization of the lesion. The awareness of medical practitioners and the timely diagnosis of OCD lesions in OHAs are key to favorable outcomes.

Abstract
INTRODUCTION Sports activity can cause elbow osteoarthritis, which subsequently induces bone deformity. Osteochondritis dissecans (OCD) of the capitellum develops defects of articular surfaces and can exacerbate bone deformity. This study aimed to investigate whether OCD exacerbates deformities in sports-related elbow osteoarthritis. MATERIALS AND METHODS Twenty-one patients who underwent bilateral computed tomography preoperatively followed by surgery for sports-related elbow osteoarthritis were included. Patients were divided into two groups according to the presence or absence of an OCD history: OCD + (n = 6) and OCD- (n = 15). Bilateral three-dimensional bone models of the humerus, ulna, and radius were created using computed tomography data, and bone deformities were extracted by subtracting healthy mirror models from the affected models using a Boolean operation. Bone deformities were divided into 22 regions in the 3 bones. The volume of the deformity was estimated by correlating the anteroposterior and lateral diameters of the OCD and by comparing the two groups. RESULTS The anteroposterior diameter of the OCD correlated with the articular surface of the medial trochlear notch, whereas the lateral diameter correlated with the whole ulna, medial gutter of the ulna, whole radius, and lateral side of the radial head. The deformities were 2.2 times larger in the whole humerus, 1.9 times larger in the whole ulna, and 3.0 times larger in the whole radius in the OCD + group than in the OCD- group. The deformities were significantly larger in the OCD + group than in the OCD- group in the radial fossa, posterior capitellum, medial gutter, and lateral gutter in the humerus, medial gutter in the ulna, and lateral, anterior, and posterior sides of the radial head. CONCLUSION Larger OCD exacerbated deformity in elbow OA, and the presence of OCD exacerbated deformities in sports-related elbow OA. These results demonstrate the highlight of preventing OCD progression.

Seamless and early gap healing of osteochondral defects by autologous mosaicplasty combined with bioactive supramolecular nanofiber-enabled gelatin methacryloyl (BSN-GelMA) hydrogel. Bioact Mater 2023; 19:88-102. [PMID: 35441114 PMCID: PMC9005961 DOI: 10.1016/j.bioactmat.2022.03.038] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 03/04/2022] [Accepted: 03/25/2022] [Indexed: 12/02/2022] Open
Abstract
Autologous mosaicplasty is a common approach used to treat osteochondral defects in clinical practice. Gap integration between host and transplanted plugs requires bone tissue reservation and hyaline cartilage regeneration without uneven surface, graft necrosis and sclerosis. However, poor gap integration is a serious concern, which eventually leads to deterioration of joint function. To deal with such complications, this study has developed a strategy to effectively enhance integration of the gap region following mosaicplasty by applying injectable bioactive supramolecular nanofiber-enabled gelatin methacryloyl (GelMA) hydrogel (BSN-GelMA). A rabbit osteochondral defect model demonstrated that BSN-GelMA achieved seamless osteochondral healing in the gap region between plugs of osteochondral defects following mosaicplasty, as early as six weeks. Moreover, the International Cartilage Repair Society score, histology score, glycosaminoglycan content, subchondral bone volume, and collagen II expression were observed to be the highest in the gap region of BSN-GelMA treated group. This improved outcome was due to bio-interactive materials, which acted as tissue fillers to bridge the gap, prevent cartilage degeneration, and promote graft survival and migration of bone marrow mesenchymal stem cells by releasing bioactive supramolecular nanofibers from the GelMA hydrogel. This study provides a powerful and applicable approach to improve gap integration after autologous mosaicplasty. It is also a promising off-the-shelf bioactive material for cell-free in situ tissue regeneration. A novel strategy that can effectively enhance post-mosaicplasty interstitial integration was developed. The bioactive supramolecular nanofibers (BSN) exhibited comparable bioactivity to insulin-like growth factor-1 (IGF-1). The BSN-GelMA hydrogel is a promising off-the-shelf bioactive material for cell-free in situ tissue regeneration.

Abstract
PURPOSE Osteochondritis dissecans (OCD) of the capitellum is often treated by marrow stimulation techniques with good long-term outcomes. Magnetic resonance imaging (MRI) can be used to characterize the healing of cartilage repair tissue. However, no formal system exists for assessment of cartilage healing after marrow stimulation in capitellar OCD. The aims of this study were to describe the postoperative MRI appearance of capitellar repair cartilage after debridement and marrow stimulation for capitellar OCD and assess differences between symptomatic and asymptomatic patients. METHODS This was a retrospective study of patients with capitellar OCD who underwent arthroscopic debridement and marrow stimulation and had a postoperative MRI to assess healing. The classification system developed by Marlovits and colleagues (Magnetic Resonance Observation of Cartilage Repair Tissue) was used to quantitatively profile the cartilage repair tissue in comparison to adjacent "normal" cartilage. Study participants completed an online survey to correlate outcomes with cartilage appearance. RESULTS Eleven patients who underwent MRI for routine evaluation (asymptomatic), and 18 who underwent MRI for symptoms were identified. Overall, 59% of defects were completely filled, and in 83%, the cartilage surface had ulcerations or fibrillations. The cartilage variables were similar between symptomatic and asymptomatic patients. Capitellar subchondral bone edema was observed on the MRI of every patient who underwent a reoperation and was present in only 62% of those who did not. Clinical scores did not correlate with MRI cartilage findings, but the small sample size limited conclusions regarding clinical outcomes related to postoperative cartilage features seen on MRI. CONCLUSIONS This detailed assessment of cartilage appearance by MRI after marrow stimulation for capitellar OCD demonstrated that incomplete cartilage fill was common in both symptomatic and asymptomatic patients. Those requiring a second surgery were more likely to demonstrate subchondral bone edema. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic IV.

Abstract
BACKGROUND The optimum management of osteochondritis dissecans (OCD) of the capitellum is a widely debated subject. PURPOSE To better understand the efficacy of different surgical modalities and nonoperative treatment of OCD as assessed by radiological and clinical outcomes and return to sports. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS A systematic review of all treatment studies published between January 1975 and June 2020 was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A total of 76 clinical studies, including 1463 patients, were suitable for inclusion. Aggregate analysis and subgroup analysis of individual patient data were performed to compare the functional and radiographic outcomes between the various nonoperative and surgical treatment options for capitellar OCD. A unified grading system (UGS; grades 1-4) was developed from existing validated classification systems to allow a comparison of patients with similar-grade OCD lesions in different studies according to their treatment. Patient-level data were available for 352 patients. The primary outcome measures of interest were patient-reported functional outcome, range of motion (ROM), and return to sports after treatment. The influences of the capitellar physeal status, location of the lesion, and type of sports participation were also assessed. Each outcome measure was evaluated according to the grade of OCD and treatment method (debridement/microfracture, fragment fixation, osteochondral autograft transplantation [OATS], or nonoperative treatment). RESULTS No studies reported elbow scores or ROM for nonoperatively treated patients. All surgical modalities resulted in significantly increased postoperative ROM and elbow scores for stable (UGS grades 1 and 2) and unstable lesions (UGS grades 3 and 4). There was no significant difference in the magnitude of improvement or overall scores according to the type of surgery for stable or unstable lesions. Return to sports was superior with nonoperative treatment for stable lesions, whereas surgical treatment was superior for unstable lesions. Patients with an open capitellar physis had superior ROM for stable and unstable lesions, but there was no correlation with lesion location and the outcomes of OATS versus fragment fixation for high-grade lesions. CONCLUSION Nonoperative treatment was similar in outcomes to surgical treatment for low-grade lesions, whereas surgical treatment was superior for higher grade lesions. There is currently insufficient evidence to support complex reconstructive techniques for high-grade lesions compared with microfracture/debridement alone.

A high rate of children and adolescents return to sport after surgical treatment of osteochondritis dissecans of the elbow: a systematic review and meta-analysis. Knee Surg Sports Traumatol Arthrosc 2021; 29:4041-4066. [PMID: 33620512 DOI: 10.1007/s00167-021-06489-9] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Accepted: 02/03/2021] [Indexed: 11/27/2022]
Abstract
PURPOSE The purpose of this systematic review was to determine the return to sport rates following surgical management of ostechondritis dissecans of the elbow. METHODS The databases EMBASE, PubMed, and MEDLINE were searched for relevant literature from database inception until August 2020 and studies were screened by two reviewers independently and in duplicate for studies reporting rates of return to sport following surgical management of posterior shoulder instability. A meta-analysis of proportions was used to combine the rates of return to sport using a random effects model. A risk of bias assessment was performed for all included studies using the MINORS score. RESULTS Overall, 31 studies met inclusion criteria and comprised of 548 patients (553 elbows) with a median age of 14 (range 10-18.5) and a median follow-up of 39 months (range 5-156). Of the 31 studies included, 14 studies (267 patients) had patients who underwent open stabilization, 11 studies (152 patients) had patients who underwent arthroscopic stabilization, and 6 studies (129 patients) had patients who underwent arthroscopic-assisted stabilization. The pooled rate of return to any level of sport was 97.6% (95% CI 94.8-99.5%, I2 = 32%). In addition, the pooled rate of return to the preinjury level was 79.1% (95% CI 70-87.1%, I2 = 78%). Moreover, the pooled rate of return to sport rate at the competitive level was 86.9% (95% CI 77.3-94.5%, I2 = 64.3%), and the return to sport for overhead athletes was 89.4% (95% CI 82.5-95.1%, I2 = 59%). The overall return to sport after an arthroscopic procedure was 96.4% (95% CI 91.3-99.6%, I2 = 1%) and for an open procedure was 97.8% (95% CI 93.7-99.9%, I2 = 46%). All functional outcome scores showed improvement postoperatively and the most common complication was revision surgery for loose body removal (19 patients). CONCLUSION Surgical management of osteochondritis dissecans of the elbow resulted in a high rate of return to sport, including in competitive and overhead athletes. Similar rates of return to sport were noted across both open and arthroscopic procedures. LEVEL OF EVIDENCE Level IV.

Abstract
This review presents the current understanding of the etiology, pathogenesis, and how to diagnose and treat osteochondritis dissecans (OCD) at the elbow joint followed by an analysis of particular characteristics and outcomes of the treatment. OCD is seen in patients with open growth plates (juvenile OCD [JOCD] and in adults [AOCD] with closed growth plates [adult OCD). The etiology at smaller joints remains as unclear as for the knee. Mechanical factors (throwing activities [capitulum] seem to play an important role. Clinical symptoms are unspecific. Thus, imaging techniques are most important for the diagnosis. In low-grade and stable lesions, treatment involves rest and different degrees of immobilization until healing. When surgery is necessary, the procedure depends on the OCD stage and on the state of the cartilage. With intact cartilage, retrograde procedures are favorable while with damaged cartilage, several techniques are used. Techniques such as drilling and microfracturing produce a reparative cartilage while other techniques reconstruct the defect with osteochondral grafts or cell-based procedures such as chondrocyte implantation. There is a tendency toward better results when reconstructive procedures for both the bone and cartilage are used. In addition, comorbidities at the joint have to be treated. Severe grades of osteoarthritis are rare.

Abstract
➤ Osteochondritis dissecans occurs most frequently in the active pediatric and young adult populations, commonly affecting the knee, elbow, or ankle, and may lead to premature osteoarthritis. ➤ While generally considered an idiopathic phenomenon, various etiopathogenetic theories are being investigated, including local ischemia, aberrant endochondral ossification of the secondary subarticular physis, repetitive microtrauma, and genetic predisposition. ➤ Diagnosis is based on the history, physical examination, radiography, and advanced imaging, with elbow ultrasonography and novel magnetic resonance imaging protocols potentially enabling early detection and in-depth staging. ➤ Treatment largely depends on skeletal maturity and lesion stability, defined by the presence or absence of articular cartilage fracture and subchondral bone separation, as determined by imaging and arthroscopy, and is typically nonoperative for stable lesions in skeletally immature patients and operative for those who have had failure of conservative management or have unstable lesions. ➤ Clinical practice guidelines have been limited by a paucity of high-level evidence, but a multicenter effort is ongoing to develop accurate and reliable classification systems and multimodal decision-making algorithms with prognostic value.

Abstract
BACKGROUND The choice of surgical option for unstable large capitellar osteochondritis dissecans (OCD) lesions in skeletally immature athletes remains controversial. PURPOSE/HYPOTHESIS The purpose was to investigate functional and radiographic outcomes after arthroscopic fragment resection and osteochondral autograft transplantation (OAT) for unstable large capitellar OCD lesions in skeletally immature athletes with a minimum 5 years' follow-up. We hypothesized that the outcomes after OAT for large capitellar OCD lesions would be superior to those after arthroscopic fragment resection. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A total of 19 elbows in 19 patients (17 male and 2 females) who underwent arthroscopic resection were assigned to group 1 (mean age, 14 years [range, 13-15 years]), whereas 29 elbows in 29 patients (29 male) who underwent OAT were assigned to group 2 (mean age, 14 years [range, 13-15 years]), with the mean follow-up of 8 (range, 5-11 years) and 7 (range, 5-13 years) years, respectively. All OCD lesions were larger than one-half of the radial head diameter. Functional scores, patient satisfaction, and range of motion were compared between the groups. Radiographic changes, including superior migration, radial head enlargement, and osteoarthritis (OA) grade, were examined. RESULTS All patients returned to sports activity. Functional scores, patient satisfaction, and flexion at the final follow-up were significantly improved in both groups compared with preoperative values, and differences were not significant between groups at the final follow-up. Extension showed a significant improvement in both groups (group 1: -17° to 0°; group 2: -18° to -6°; P < .001). Extension in group 1 was significantly better than that in group 2 at the final follow-up (P = .045). No elbows developed postoperative severe OA in group 1, whereas 3 elbows in group 2 had grade 3 OA; these 3 elbows had preoperative superior migration and radial head enlargement. CONCLUSION No differences were observed in clinical and radiographic outcomes between patients undergoing arthroscopic fragment resection and OAT, except for elbow extension, at a minimum 5 years' follow-up. We believe that for adolescents with large capitellar OCD lesion, OAT is a good option for skeletally immature elbows and that arthroscopic fragment resection is a reliable and less invasive surgical option for relatively mature elbows.

[PMID: 34250159 PMCID: PMC8237226 DOI: 10.1177/2325967121989676] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Accepted: 10/16/2020] [Indexed: 11/16/2022] Open
Abstract
Background: One of the most important limitations of osteochondral autograft transplant
is the adverse effect on donor sites in the knee. Ultrapurified alginate
(UPAL) gel is a novel biomaterial that enhances hyaline-like cartilage
repair for articular defects. To avoid the need for knee cartilage
autografting when treating osteochondritis dissecans (OCD) of the
capitellum, we developed a surgical procedure involving a bone marrow
stimulation technique (BMST) augmented by implantation of UPAL gel. Hypothesis: BMST augmented by UPAL gel implantation improves the cartilage repair
capacity and provides satisfactory clinical outcomes in OCD of the
capitellum. Study Design: Case series; Level of evidence, 4. Methods: A total of 5 athletes with advanced capitellar OCD in the dominant elbow
underwent BMST augmented by implantation of UPAL gel. The osteochondral
defects were filled with UPAL gel after BMST. At a mean follow-up of 97
weeks, all patients were evaluated clinically and radiographically. Results: At final follow-up, all 5 patients had returned to competitive-level sports,
and 4 patients were free from elbow pain. The mean Timmerman-Andrews score
significantly improved from 100 to 194 points. Radiographically, all
patients exhibited graft incorporation and a normal contour of the
subchondral cortex. Magnetic resonance imaging showed that the preoperative
heterogeneity of the lesion had disappeared, and the signal intensity had
returned to normal. Arthroscopic examinations consistently exhibited
improvement in the International Cartilage Regeneration and Joint
Preservation Society (ICRS) grade of lesions from 3 or 4 to 1 or 2 in 4
patients at 85 weeks postoperatively. Histologic analysis of biopsy
specimens revealed an average total ICRS Visual Assessment Scale II
histologic score of 1060. Conclusion: The acellular cartilage repair technique using UPAL gel for advanced
capitellar OCD provided satisfactory clinical and radiographic results. The
present results suggest that this novel technique is a useful, minimally
invasive approach for treating cartilaginous lesions in athletes.

[PMID: 33534261 PMCID: PMC7899490 DOI: 10.1097/corr.0000000000001468] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Accepted: 08/04/2020] [Indexed: 01/31/2023]
Abstract
BACKGROUND Stress from overhead throwing results in morphologic changes to the shoulder in youth baseball players. With greater valgus torque stresses, the elbow experiences injuries specifically attributed to throwing. However, no previous work that we know of has assessed throwing-related morphologic changes of the elbow without associated conditions. QUESTIONS/PURPOSES (1) Do children who play competitive baseball have enlargement or overgrowth of their radial head shape and/or capitellum compared with the nondominant elbow on MRI? (2) Do children who stop playing year-round baseball have less enlargement of the lateral elbow structures than children who maintain a high level of play? METHODS A prospective study was conducted between 2015 and 2018 on preadolescent boys who underwent voluntary MRI of their bilateral elbows before the start of the spring baseball season. Twenty-six children agreed to participate out of a four-team league that was asked to participate; their first MRI was obtained at a mean (range) age of 12 years (10 to 13). We also obtained their history related to throwing and performed a physical examination. Players had a mean of 5.6 years of playing before their first MRI, and half the children (13 of 26) were year-round baseball players. Sixty-two percent (16 of 26) reported being either or both a pitcher or catcher as their primary position. No child was excluded from participation. Three years later, these boys were asked to return for repeat MRI and physical examinations. Fifty-eight percent (15 of 26) of players were still playing at the 3-year MRI. Continued play or new onset of pain was documented. Radiographic measurements were then compared between dominant and nondominant arms, and the differences of these changes were compared between those who had continued playing during the study period and those who had quit. The measurements were made in all three planes of the radial head and capitellum, both osseous and cartilaginous. Measurement intrarater and interrater reliability were in the good-to-excellent range (intraclass correlation coefficient 0.77 to 0.98). RESULTS When we compared dominant and nondominant arms, we found there was no dominant arm overgrowth (difference between baseline and 3-year measurements) in any measurement; for example, sagittal capitellum measurements in dominant arms were 2.5 ± 1.1 mm versus non-dominant arms: 2.8 ± 1.1 mm (mean difference -0.23 [95% CI -0.55 to 0.08]; p = 0.13). There was only undergrowth of the cartilaginous axial diameter of the radial head (change in dominant: 2.5 ± 1.3 mm; change in nondominant: 3.2 ± 1.7 mm; mean difference -0.64 mm [95% CI -1.2 to -0.06]; p = 0.03). There was no enlargement of the lateral elbow structures when children who continued to play were compared with children who stopped playing; for example, the difference in the bone-only growth ratio of the sagittal radial head to humerus of those still playing was 0.001 ± 0.03 and it was 0.01 ± 0.03 for those not playing (mean difference -0.01 [95% CI -0.04 to 0.01]; p = 0.29). CONCLUSION In healthy children who play baseball for multiple years between the ages of 6 to 11 years, continued torque at the elbow from throwing does not result in morphologic changes as it does in the shoulder. Despite evidence that injuries and surgery because of long-term participation in a throwing sport results in a larger radial head and capitellum, our study presents evidence that outside an injured elbow, throwing alone does not appear to change the morphology of the lateral elbow. Therefore, changes to the radial head size could presuppose other elbow pathology and future study could be performed to better evaluate the correlation. LEVEL OF EVIDENCE Level I, prognostic study.

Abstract
BACKGROUND Osteochondral autograft transplant (OAT), a surgical treatment for capitellar osteochondritis dissecans (OCD), has favorable rates of elbow recovery and return to sports in adolescents. However, few reports have investigated how long patients continue to play baseball after OAT and their satisfaction with their treatment outcome. PURPOSE To evaluate the rate of boys who played baseball and received OAT for OCD in junior high school or earlier (age <15 years) and continued to play baseball in high school and the players' satisfaction with their elbow function during play. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A total of 32 elbows of boys who played baseball and received OAT at age ≤15 years (mean, 14.1 years) were examined and divided into pitcher (n = 11) and nonpitcher (n = 21) groups according to their player position before surgery. The clinical Timmerman-Andrews score at the end of their high school baseball, participation percentage of players who continued to play baseball, and satisfaction level during play (on a scale of 0-10 during pitching and batting and in a 4-choice format) were compared between the 2 groups. RESULTS The Timmerman-Andrews scores significantly improved after surgery in both groups, with no significant difference between the groups. Of the 32 players, 30 (93.8%) continued to play baseball throughout high school, including all players in the pitcher group and 19 (90.5%) of those in the nonpitcher group. The percentage of players who continued to pitch was 55.6% (6/11) in the pitcher group. Satisfaction with elbow joint function at the time of pitching was significantly lower in the pitcher group. Further, 5 players reported being "a little unsatisfied" because of elbow pain during pitching. All of the players indicated satisfaction with elbow function during batting. CONCLUSION The percentage of players who received OAT for OCD in junior high school and continued to play baseball in high school was favorable. However, satisfaction with elbow function during throwing was lower in pitchers than in nonpitchers. CLINICAL RELEVANCE Before surgery, consent should be obtained from patients who are pitchers after it is explained that satisfaction with elbow joint function during pitching could be decreased after OAT.

Abstract
PURPOSE To systematically evaluate the outcomes and complications of osteochondral autograft transfer (OAT) and osteochondral allograft transplantation (OCA) for the surgical treatment of capitellar osteochondritis dissecans (OCD). METHODS A literature search was conducted across 3 databases (PubMed, Cochrane, and CINAHL [Cumulative Index to Nursing and Allied Health Literature]) from database inception through December 2019 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Individual study quality was assessed using the Methodological Index for Non-randomized Studies scale. Studies were published between 2005 and 2019. RESULTS Eighteen studies consisting of 446 elbow OCD lesions treated with OAT surgery were included. There was a single OCA study eligible for inclusion. Patient ages ranged from 10 to 45 years. Of the OAT studies, 4 used autologous costal grafts whereas the remainder used autografts from the knee. Outcome measures were heterogeneously reported. A significant improvement in Timmerman-Andrews scores from preoperatively to postoperatively was reported in 9 of 10 studies. Return-to-play rates to the preinjury level of competitive play ranged from 62% to 100% across 16 studies. Significant improvement in motion, most often extension, was noted in most studies. Reported complication, reoperation, and failure rates ranged from 0% to 11%, 0% to 26%, and 0% to 20%, respectively. When used, knee autografts resulted in low donor-site morbidity (Lysholm scores, 70-100). CONCLUSIONS OAT surgery for large, unstable OCD lesions of the capitellum reliably produced good outcomes, few complications, and a high rate of return to competitive play. Complications are relatively uncommon, and donor-site morbidity is low. Less is known about the performance of OCA given the paucity of available literature. LEVEL OF EVIDENCE Level IV, systematic review of Level II to IV studies.

Abstract
BACKGROUND Autologous osteochondral grafting (OG) is an option in the treatment of capitellar osteochondritis dissecans (COCD). However, radiographic healing after this procedure has not been well documented. PURPOSE To develop a magnetic resonance imaging (MRI)-based scoring system specific for evaluating healing after single-plug OG in COCD and to evaluate correlation between radiographic healing and early clinical outcomes. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 3. METHODS Between 2014 and 2017, 183 elbows with COCD were enrolled in a prospective registry. A total of 61 elbows in 59 patients underwent single-plug OG. Of these, 52 elbows in 50 patients had pre- and postoperative MRI scans. Postoperative MRI and clinical outcome data from this group were used to develop the novel BOGIE score (Boston Osteochondral Graft Incorporation in the Elbow), with a possible range of 4 to 12. RESULTS Median age at surgery was 14.2 years (interquartile range, 13.1-15.0 years). Median clinical follow-up after OG was 12.4 months (interquartile range, 9.5-16.9 months; range, 6-53 months). Compared with before surgery, elbow function at 6 months after surgery and at latest follow-up was significantly improved as measured by the Timmerman and Andrews score (TAS; median: 145 before surgery, 185 at 6 months after surgery, 190 at latest follow-up; P < .001, before vs after surgery), as well as the short version of Disabilities of the Arm, Shoulder and Hand score; median: 21 before surgery, 7 at 6 months after surgery, and 0 at latest follow-up; P < .001 before surgery vs after surgery). Median BOGIE score at 6 months after surgery was 10 (range, 4-12). BOGIE score intraobserver reliability was 0.90 (95% CI, 0.82-0.94) for reader 1 and 0.91 (95% CI, 0.86-0.95) for reader 2. Interobserver reliability between the readers was 0.86 (95% CI, 0.78-0.92). Correlation was observed between the 6-month BOGIE score and the concurrent postoperative objective TAS (P < .001) as well as total TAS (P = .01) but not the subjective TAS (P = .08). Patients who underwent subsequent secondary surgery for persistent symptoms had a significantly lower postoperative BOGIE score at 6 months than those who did not (median, 7.8 vs 10.3; P = .016). CONCLUSION Quantitative evaluation for radiologic healing after single-plug OG in COCD is possible. The MRI-based BOGIE score appears to correlate with early clinical function and may be useful as an adjunct tool in decision making on activity progression. The use of a standardized MRI score may improve comparability of outcomes after OG in the literature.

Abstract
Osteochondritis dissecans (OCD) of the capitellum is a leading cause of elbow disability in adolescent baseball players. Previous studies have not found an association of player position with capitellar OCD. Elbow pain and a longer playing history might be related to progression of capitellar OCD but do not in themselves increase the risk of development of the condition. The cause of capitellar OCD is likely to include a combination of repetitive microtrauma and internal factors, such as ischemia and genetic predisposition. A combination of radiography, computed tomography, magnetic resonance imaging, and ultrasonography have aided our understanding of the pathology of capitellar OCD. Screening using ultrasonography enables early detection and provides an opportunity for successful conservative treatment. Treatment has conventionally included both operative and nonoperative measures based on the stage and size of the lesion, skeletal maturity, subjective symptoms, and structural integrity of the cartilage. Early-stage lesions respond better to nonoperative treatment than those in more advanced stages. Operative indications include persistent symptoms despite nonoperative treatment, symptomatic loose bodies, and displacement or detachment of fragments. J. Med. Invest. 67 : 217-221, August, 2020.

Abstract
PURPOSE To compare the histologic features of the cartilage from the capitellum with 2 proposed alternative donor sites from the ipsilateral elbow in the treatment of capitellar osteochondritis dissecans (OCD): the nonarticulating part of the radial head and the nonarticulating lateral side of the olecranon tip. METHODS Ten human cadaveric elbow specimens with macroscopically normal articular surfaces were used to obtain 5-mm osteochondral grafts: 10 from the capitellum (60° anteriorly relative to the humeral shaft), 10 from the radial head (nonarticulating part at 80°), and 4 from the olecranon (lateral side of the olecranon tip). Grafts were fixated in formalin (4% formaldehyde), decalcified, and processed into standard 8-μm-thick hematoxylin and eosin-and Toluidine Blue-stained sections. These were assessed for cartilage thickness, shape of articular surface, and 13 histologic parameters of the International Cartilage Repair Society II. Olecranon scores were excluded from statistical analysis. RESULTS Mean cartilage thickness was 1.5 ± 0.22 mm at the capitellum; 1.3 ± 0.34 mm at the radial head; and 1.9 ± 1.0 mm at the olecranon. There was no difference in cartilage thickness between the capitellum and radial head (P = .062). All grafts demonstrated a convex articular surface. International Cartilage Repair Society II scores ranged from 82 to 100 for the capitellum, from 81 to 100 for the radial head, and from 67 to 87 for the olecranon tip. There was less chondrocyte clustering at the capitellum (84 ± 14) than in the radial head (94 ± 3.2; P = .019). Mid/deep zone assessment of the capitellum scored higher (97 ± 6.7) than the radial head (91 ± 4.6; P = .038). CONCLUSIONS This study demonstrates appropriate histologic similarities between the cartilage from the capitellum and 2 alternative donor sites of the ipsilateral elbow in the treatment of capitellar OCD: the nonarticulating part of the radial head and the nonarticulating lateral side of the olecranon tip. CLINICAL RELEVANCE From an histologic point of view, there seem to be no obstacles to use grafts from these alternative donor sites for reconstruction of the capitellum when performing osteochondral autologous transplantation.

Abstract
BACKGROUND Osteochondritis dissecans of the humeral capitellum (capitellar OCD) is a common injury among adolescent throwing athletes. Some younger patients with incomplete maturity of the epiphysis and early-stage capitellar OCD are good candidates for nonoperative treatment. However, during initial examination, predicting the need for surgical treatment in patients with capitellar OCD is difficult. PURPOSE To perform multivariate ordered logistic regression analysis of data obtained from patients' medical records and images on initial examination and identify the predictors of unsuccessful nonoperative management of capitellar OCD. STUDY DESIGN Cohort study (prognosis); Level of evidence, 2. METHODS This study included 245 elbows with capitellar OCD (all male; mean age, 14 years [range, 10-27 years]). Patients were divided into 3 groups comprising 148 elbows requiring an immediate operation on initial examination, 48 requiring nonsurgical treatment, and 49 requiring an operation after nonoperative management. Baseline data and radiographic parameters, such as lesion location, lesion size, modified Minami classification, radial head size, skeletal age difference between both elbows on initial examination, lesion size on computed tomography, and staging on magnetic resonance imaging, were retrospectively reviewed. Univariate and multivariate ordered logistic regression analyses of spontaneous healing of the lesion were conducted. RESULTS Univariate logistic regression analysis showed that radial head enlargement and skeletal age difference were significantly associated with spontaneous healing. In multivariate ordered logistic regression analysis, radial head enlargement (anteroposterior and lateral) and skeletal age difference were significant predictors of lack of spontaneous healing (odds ratio [OR], 2.76, P =.025; OR, 7.92, P =.026; and OR, 1.84, P =.0089, respectively). CONCLUSION To predict spontaneous healing in the moderate stage, plain radiographs would be important to evaluate radiocapitellar congruity and skeletal age. This study showed that preoperative radiographic findings of radial head enlargement and advanced skeletal age of the throwing side compared with that of the nonthrowing side were predictors of advanced-stage capitellar OCD. Despite several limitations, the statistical significance and correlations herein provide important information on preoperative surgical planning to surgeons.

Abstract
BACKGROUND For treatment of advanced elbow osteochondritis dissecans (OCD), we have used surgical treatment. Although favorable treatment outcomes have been reported for centrally located OCD, treatment outcomes are generally questionable and the choice of surgical method is controversial for laterally located OCD. Our purpose was to evaluate the treatment outcomes based on lesion location. METHODS The patients were 30 young (mean age, 14 years) male athletes who underwent surgical treatment of elbow OCD and were monitored for more than 1 year. Osteochondral autografts harvested from the knee were transplanted to centralized (13 patients) or lateral localized (9 patients) OCD lesions. For lateral widespread (8 patients) OCD lesions, a detached osteochondral fragment was fixed using small osteochondral plugs. When the remaining cartilage defect was large after fragment fixation, a large-sized osteochondral plug was transplanted to the defect. Treatment outcomes were evaluated by the Japanese Orthopaedic Association score, elbow range of motion (ROM), and radiographic findings. RESULTS The Japanese Orthopaedic Association score significantly improved in patients with centralized, lateral localized, and lateral widespread types of OCD. ROM significantly improved in patients with centralized and lateral localized, and they returned to playing sports within 6 months. However, patients with lateral widespread OCD exhibited no significant ROM improvement, and returning to sports was difficult for 3 patients because of poor osseous integration of the fixed osteochondral fragment. CONCLUSIONS Osteochondral autograft transplantation provided favorable outcomes for centralized and lateral localized elbow OCD lesions. However, for lateral widespread OCD lesions, reconstruction of the entire capitellar lesion area may be necessary.

Abstract
Background Elbow arthroscopy had good functional outcome for throwing athletes. Returning to sports is a major concern for all athletes, but only a few reports have investigated the clinical factors related to the duration of returning to sports. The present study evaluates the efficacy of elbow arthroscopic surgery on throwing elbows with osteoarthritis and defines the clinical factors related to the duration of the returning to sports. Methods This was a retrospective study with fifteen active baseball throwing athletes with elbow osteoarthritis who were treated with elbow arthroscopy. Perioperative clinical factors were analyzed for functional outcomes. A multiple linear regression analysis was used to analyze the clinical factors associated with the duration of returning to training and sports. Results The 15 patients’ mean age was 27 years. The mean follow-up time was 2.6 years. The mean procedural complexity was 3.1 ± 1.6 (range 1–6). The elbow total range of motion (ROM) improved significantly from 100.7 ± 28.7° to 125.7 ± 18.5° (p = 0.001). The terminal flexion range of the elbow increased significantly from 116.0 ± 22.6° to 130.0 ± 13.2° (p = 0.001), and the terminal extension range improved from 15.3 ± 11.1° to 4.3 ± 5.9° (p = 0.001). Before the operation, the average subjective patient outcome for return to sports (SPORTS) score was 3.4 ± 1.5, which increased significantly to 9.67 ± 0.45 (p = 0.003) at the last follow-up. The multiple linear regression analysis revealed that higher procedural complexity hinders the athletes from returning to competition. Conclusions Elbow arthroscopy offered highly satisfactory results in the throwing elbows of elite athletes and significantly improved the range of motion and SPORTS score. The procedural complexity was significantly related to the duration of returning to competition. Early and aggressive arthroscopic intervention is recommended for elite throwing athletes with elbow osteoarthritis who fail to respond to conservative treatment.
