Abstract
BACKGROUND Osteochondritis dissecans (OCD) of the humeral capitellum is a rare and challenging condition to treat. Several surgical options exist, but in the last few years, the pendulum has swung from debridement and microfracture to restoration of the articular surface. Osteochondral autografts from the rib and knee have been described, but donor-site morbidity is a concern. PURPOSE To expand the results of fresh osteochondral allograft transplantation (FOCAT) in a previously published report with inclusion of additional patients and a longer follow-up period. STUDY DESIGN Case series; Level of evidence, 4. METHODS After institutional review board approval, the charts of patients who underwent FOCAT for OCD of the capitellum between 2006 and 2022 by a single surgeon were reviewed. The majority of cases (94%) had unstable lesions (Minami grades 2 and 3). A trial of nonoperative treatment had failed in all. All patients underwent diagnostic arthroscopy, followed by a mini-open, ligament-sparing approach with grafting using commercially available guides and instruments. RESULTS A total of 35 patients were identified, of whom 25 were male. The mean age was 16 ± 3.9 years (range, 11-32 years). There were 24 baseball players (19 pitchers and 5 position players), 5 gymnasts, 3 cheerleaders/tumblers, 1 tennis player, 1 student (who did not participate in athletics), and 1 patient with avascular necrosis from chemotherapy. Eighteen patients had a mean flexion contracture of 14.1°± 11.9°. A single osteochondral allograft plug was used in 23 patients (mean diameter, 11.3 ± 2.8 mm), and 12 patients required 2 plugs (Mastercard technique). The mean follow-up was 92.6 ± 54.5 months (range, 24-204 months). There was significant improvement in Oxford (from 25.5 ± 4.9 to 46.7 ± 3.5; P < .00001) and visual analog scale for pain (from 7.5 ± 2 to 0.3 ± 1.0; P < .0001) scores. The mean Single Assessment Numeric Evaluation score at the time of follow-up was 90.6 ± 10.8 (range, 60-100). In overhead athletes, there was significant improvement in the Kerlan-Jobe Orthopaedic Clinic score (from 40.8 ± 11.8 to 90.6 ± 10.8; P < .00001). A postoperative magnetic resonance imaging scan was obtained in 16 (46%) patients at a mean of 32.6 months. In all cases, the graft was incorporated. All overhead athletes were able to return to their sport and perform at the same level or higher for >2 years. Two elbows required a subsequent arthroscopy for loose-body removal; otherwise, there were no other complications. CONCLUSION FOCAT is an excellent option for treating OCD lesions of the humeral capitellum. Excellent outcomes and high return-to-sport rates were observed, with midterm follow-up showing no graft failures. FOCAT eliminates donor-site morbidity.

Abstract
Background Capitellar osteochondritis dissecans (OCD) lesions are common in athletes. Osteochondral autograft transfer (OAT) is one possible treatment option, though outcomes including return to sport (RTS) data are limited to small series. The purpose of this study was to systematically review RTS following OAT for capitellar OCD lesions. Our secondary objectives were to evaluate patient-reported outcomes (PROs), range of motion (ROM), and complications after OAT. Methods PubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature were searched for peer-reviewed articles on "osteochondral autograft transfer" and related terms for capitellar OCD lesions. Articles were included if they reported an RTS rate and had a follow-up time point of at least 12 months. Data on RTS rates, PRO measures, complications, and ROM were extracted. Articles were assessed for methodological quality using the Methodological Index for Non-randomized Studies criteria. Results Six hundred sixty-six articles were retrieved, and 24 articles (470 patients) met the inclusion criteria. In total, 454/470 patients (97%) returned to sports following OAT for OCD. The RTS rate ranged from 79% to 100%. Return to previous level of performance ranged from 10% to 100%. Timmerman-Andrews postoperative scores (range = 169-193) were most often reported, with 87% of patients showing scores within the excellent range. Disabilities of the Arm, Shoulder, and Hand and Japanese Orthopedic Association scores were also excellent postoperatively for all studies reporting, with higher scores among centralized lesions vs. lateral. Conclusions Following OAT for capitellar OCD lesions, RTS rates are high; however, athletes should be counseled on the potential of a return to lower performance or the need to change positions. Lateral lesion location may negatively impact outcomes. PRO scores are typically excellent and postoperative ROM consistently improves. This information helps counsel patients regarding expectations and outcomes of OAT for OCD of the capitellum.

Abstract
Osteochondritis dissecans of the capitellum is debilitating and is a potentially sports career-ending injury in a young and athletic population. Osteochondritis dissecans typically occurs in patients between the ages of 10 and 24 years, and boys are more commonly affected than girls. Conventional radiographs have low diagnostic accuracy, and magnetic resonance imaging (with or without contrast) or computed tomography may aid in accurate diagnosis. The primary indication for non-operative treatment is the presence of an intact cartilage cap on magnetic resonance imaging, indicating a "stable lesion." However, if operative treatment is necessary, various surgical procedures are available when operative treatment for an osteochondritis dissecans of the capitellum is considered, including open or arthroscopic removal of loose bodies, with or without microfracturing, fragment fixation, osteochondral autograft transplantation, and osteochondral allograft transplantation. The decision-making process for selecting the appropriate treatment considers factors such as the patient's characteristics, functional limitations, and lesion morphology.

Abstract
Background Osteochondritis dissecans (OCD) of the capitellum is a well-described condition that most commonly affects adolescent throwing athletes and gymnasts. There is no gold standard rehabilitation protocol or timing for return to sport (RTS) after surgical management of OCD of the capitellum. Hypothesis/Purpose The purpose of the study was to identify in the existing literature any criteria used for RTS following surgical treatment of OCD of the capitellum. The hypothesis was that surgeons would utilize length of time rather than functional criteria or performance benchmarks for RTS. Methods Level 1 to 4 studies evaluating athletes who underwent surgery for OCD of the capitellum with a minimum follow-up of 1-year were included. Studies not describing RTS criteria, including less than 1-year follow-up, non-operative management only, and revision procedures were excluded. Each study was analyzed for RTS criteria, RTS rate, RTS timeline, sport played, level of competition, graft source (if utilized), and postoperative rehabilitation parameters. Assessment of bias and methodological quality was performed using the Coleman methodology score and RTS value assessment. Results All studies reported a rehabilitation protocol with immobilization followed by bracing with progressive range of motion. RTS rate was 80.9% (233/288). The majority of studies reported using time-based criteria for RTS (11/15). The most commonly reported timeline was 6 months (range: 3-12 months). Conclusion The overall RTS rate after surgical treatment of capitellar OCD is high with no consensus on RTS criteria. The two most consistent RTS criteria reported in the literature are return of elbow range of motion and healing demonstrated on postoperative imaging. There is a wide range of time to RTS in the literature, which may be sport dependent. Further research is needed to develop functional and performance-based metrics to better standardize RTS criteria and rehabilitation protocols.

Abstract
Osteochondritis dissecans (OCD) of the capitellum occurs relatively infrequently but can be found in young overhead-throwing athletes, most commonly in baseball players and gymnasts. Although non-operative management can effectively treat stable lesions, unstable lesions can lead to debilitating symptoms of the elbow and diminished quality of life without surgical intervention. This article reviews methods of treating OCD of the capitellum categorized by stability, size, and patient characteristics, and seeks to familiarize the reader with the appropriate selection of osteochondral allograft versus autograft in treating large, unstable lesions. We complement this review with 3 case examples, each using either an osteochondral autograft or allograft, and discuss the decision-making methodology used in each case.

Abstract
Background The goal of the osteochondral autograft transplantation (OAT) procedure is to replace both the bone and cartilage that have been compromised by osteonecrosis of the capitellum, a condition known as osteochondritis dissecans (OCD). In children, the vascularity of the capitellum is limited compared with that in adults because the physis acts as a physical barrier to vascular ingrowth from the metaphysis to the epiphysis. The necrotic subchondral bone cannot keep up with the weight-bearing demands of certain high-level athletes such as gymnasts, accumulating microfractures and eventually crumbling. Without the support of the subchondral bone, the overlying cartilage fractures and eventually comes loose, often floating around the joint as a loose body. Fibrocartilage may form to fill the void left behind but cannot restore either the structural integrity of the bone or the gliding and compressive properties of hyaline cartilage. Replacement of both the bone and the cartilage requires an osteochondral transplant. Fortunately, there are regions of the articular surface of the knee in which there is minimal load or contact and that are therefore expendable as donor osteochondral plugs. We prefer a single-plug technique whenever possible because it is easier to perform and only requires union of the plug to native bone across 1 interface. If a single plug will not cover the defect or cannot be made to match the contour of the capitellum, multiple plugs may be used (i.e., mosaicplasty). Description Place the patient with the operative side up in the lateral decubitus position with the arm in a holder. First, perform a diagnostic elbow arthroscopy. Use the proximal anteromedial portal to insert the scope across the front of the joint. Using a switching stick, make an anterolateral portal. Place a cannula to prevent having to go in and out of the joint multiple times, as this increases the risk of neurologic injury. Perform a synovectomy if necessary and remove any loose bodies. The absence of synovitis is a sign that the lesion has likely healed. Inspect the capitellum and radial head. The anterior margin of the OCD lesion of the capitellum will be barely visible as the joint is brought to extension.If the lesion is readily visible in the anterior compartment, the lesion will be too anterior to approach from an anconeus split approach. In this case, some have advocated a takedown of the lateral collateral ligament to aid in visualization from a lateral approach1. We have had good success with a direct anterior approach between the brachialis and brachioradialis, mobilizing the radial nerve laterally.If the chondral injury is extensive or includes the articular surface of the radial head, then the injury is too advanced to successfully treat with an OAT procedure. In these cases, we perform an interposition arthroplasty of the radiocapitellar joint. Radial head resection is not an option in a child because of the high risk of proximal radial migration. Radial head replacement likewise is not an option because of the high risk of failure.Switch the viewing and working portals again with use of switching sticks and repeat the process for the medial side of the joint. Make a direct posterior and a proximal posterolateral portal. Never debride on or near the medial gutter because the ulnar nerve is immediately adjacent. Establish a soft spot portal and place the scope through it. Loose bodies and extensive synovitis are typically seen in this area when the soft spot portal is used as a viewing portal. The OCD lesion should be visible through the soft spot portal. If the lesion is not readily visible with some elbow flexion, then the lesion is probably too anterior for an anconeus split approach and an anterior approach should be considered.Challenge the lesion with a probe. If the cartilage is damaged but the subchondral bone holds firm, perform a microfracture technique. If the cartilage is soft or unstable and the underlying bone is compromised, perform an OAT procedure. In the majority of cases in which the lesion is accessible posteriorly, connect the proximal posterolateral portal and the soft spot portal and split the anconeus. The lesion will be visible in deep flexion. There are several options for instrumentation from multiple manufacturers that each have their own advantages and disadvantages. Using a recipient harvester, remove the diseased bone and cartilage to a stable rim, keeping the harvester as perpendicular to the surface as possible.At the knee, make a 3-cm transverse incision directly over the superolateral corner of the lateral femoral condyle. Harvest an appropriately sized plug from the superolateral corner of the articular surface. Inspect the plug because it will often be slightly thicker on one side. Rotate the plug to match the contour of the defect in the capitellum. Mallet the donor plug into the recipient deficit with gentle taps, using as few taps as possible to limit chondrocyte injury. Fill the defect in the knee with your choice of bone substitute. Close both wounds in layers. Alternatives Other options include allograft plugs, periosteal resurfacing, bone grafting, retrograde and antegrade drilling, and observation. Rationale The OCD lesion involves both bone and cartilage. There is now ample evidence that replacing both as a unit yields the best outcomes. Expected Outcomes Approximately 90% of patients will return to sports participation, and 80% of patients can expect to return to sport at their previous level of participation1-3. Important Tips A diagnostic arthroscopy confirms the need for the OAT procedure and identifies other pathologies.Remove all of the diseased bone with the recipient harvester.Match the size and contour of the lesion as closely as possible with the plug.Immobilize the elbow in a cast for 4 weeks.
