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.

[PMID: 37714441 DOI: 10.1016/j.arthro.2023.08.075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Revised: 08/13/2023] [Accepted: 08/15/2023] [Indexed: 09/17/2023]
Abstract
PURPOSE To assess return to sport (RTS) in the high-risk young athlete population with capitellar osteochondritis dissecans (OCD) undergoing arthroscopic microfracture (MFX) with or without debridement as well as associated indications, clinical outcomes, radiographic outcomes, and complications. METHODS A literature search of all published literature in the English language from PubMed, EMBASE, Scopus, and Cochrane from database inception to April 4, 2022, was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Included studies presented demographics and outcomes for adolescent (<21 years old) patients diagnosed with capitellar OCD who underwent arthroscopic MFX (or drilling/subchondral drilling) or MFX (or drilling/subchondral drilling) with debridement (or loose body removal/chondroplasty). Studies containing multiple surgical techniques that did not distinguish characteristics and outcomes of individual patients by surgical technique were excluded. Additionally, if there was overlap in patient populations between 2 studies, the study with less outcome data was excluded. Extracted data included study properties, patient demographics, lesion characteristics, surgery details, and patient outcomes, including range of motion, outcome scores, and RTS rates. Bias was assessed via the Methodological Index for Non-Randomized Studies (MINORS). RESULTS Nine studies of 136 patients and 138 elbows met criteria. Included articles were published between 2005 and 2020 with MINORS scores of 8 to 14 (50% to 88%). The age ranged from 12.7 to 15.7 years with most patients being involved in baseball or gymnastics and a rate of dominant elbow involvement of 55% to 100%. Patient follow-up ranged from 16 to 138 months. All 9 studies reported RTS, ranging from 65% to 100%. Six of these studies categorized the level to which the patient returned, with patients RTS at the same level of competition ranging from 60% to 100%. Six studies reported complications, with a range rate of 0% to 43%; there were a total of 10 complications, 7 of which required reoperations. CONCLUSIONS Arthroscopic MFX with or without arthroscopic debridement is a safe and effective treatment for OCD lesions of the capitellum in young, athletic patients. Included studies reported improved clinical, radiographic, and patient-reported outcomes. Aside from 1 study reporting an RTS of 65%, the rate of RTS ranged from 86% to 100%. The percentage of patients returning to sport at the same level of competition ranged from 60% to 100% with a time to RTS ranging from 4.1 to 5 months. A single study reported a complication rate of 43%, while remaining studies reported complication rates between 0% and 19%, with loose bodies being the most common complication requiring reoperation. Follow-up ranged from 16 to 138 months. LEVEL OF EVIDENCE Level IV, systematic review of Level IV studies.

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
CASE A 19-year-old handballer presented with elbow pain and nonunion of the medial trochlea of the elbow. He had undergone earlier surgery for an elbow injury at 6 years of age. Revision surgery for nonunion was performed using an extra-articular method combining cylindrical bone graft and headless screw fixation. Partial union was observed, and he resumed sports after 3 months, with his limb largely pain-free and functional. At the 21-month follow-up, bone healing was complete. CONCLUSIONS Combining cylindrical bone graft and headless screw fixation using the extra-articular technique is an option for managing nonunion of the medial trochlea of the elbow.

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.

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
With an increased interest in youth sports, the burden of overhead throwing elbow injuries accompanying early single-sport focus has steadily risen. During the overhead throwing motion, valgus torque can reach and surpass Newton meters (N m) during the late cocking and early acceleration phases, which exceeds the tensile strength (22.7–33 N m) of the ulnar collateral ligament. While the ulnar collateral ligament serves as the primary valgus stabilizer between and degrees of elbow flexion, other structures about the elbow must contribute to stability during throwing. Depending on an athlete’s stage of skeletal maturity, certain patterns of injury are observed with mechanical failures resulting from increased medial laxity, lateral-sided compression, and posterior extension shearing forces. Together, these injury patterns represent a wide range of conditions that arise from valgus extension overload. The purpose of this article is to review common pathologies observed in the adolescent overhead throwing athlete in the context of functional anatomy, osseous development, and throwing mechanics. Operative and non-operative management and their associated outcomes will be discussed for these injuries.

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.

Abstract
Hypothesis This study aimed to investigate the results, indications, and limitations of absorbable pin fixation for osteochondritis dissecans of the humeral capitellum in the separation stage. Methods This study included 35 patients (mean age, 14.0 years). Patients were divided into two groups: Group A included those who obtained complete union within 6 months and Group B included those who did not observe complete union within 6 months. The clinical findings were compared between the groups. Results There were 26 and 6 patients in Groups A and B, respectively. Two patients did not obtain complete union. Clinical outcomes improved after the procedure. In univariate analysis, delayed union was associated with larger major diameter (P = .0004) and more depth (P = .03) of the osteochondral fragment measured by computed tomography, the presence of osteosclerosis in the subchondral bed on X-ray imaging (P = .003), and the presence of comminution of subchondral bone on ultrasound imaging (P = .01). In multivariate analysis, there was a significant difference only in the major diameter of the osteochondral fragment (P = .03). Receiver operating characteristic curves analysis shows that if the major diameter of the osteochondral fragment is 11 mm or less, 85% of patients achieve complete union of the osteochondral fragments within 6 months. Conclusion Absorbable pin fixation may be considered for the osteochondral fragments with major diameter of 11 mm or less and should not be considered for patients who demonstrate osteosclerosis in the subchondral bed or comminution of subchondral bone.

Abstract
Background and hypothesis It is generally considered that fragment fixation with bone pegs (FFBP) for osteochondritis dissecans (OCD) of the humeral capitellum can be indicated for stages I and II according to the International Cartilage Repair Society (ICRS) classification of OCD and it is difficult to obtain complete bone union for advanced lesions. However, the clinical and radiologic results of FFBP with cancellous bone graft for ICRS-OCD stage III with lateral wall involvement have not been described in detail. Good bone union can be achieved with the lateral wall fragment of the capitellum by FFBP in combination with refreshing the sclerotic surface at the base of the lesion and cancellous bone grafting even in ICRS-OCD stage III lesions. Methods In total, 10 adolescent baseball players with a diagnosis of OCD, a median age of 13.5 years at the time of surgery, and 26.7 months of postoperative follow-up were included. Preoperative imaging showed that all patients had lesions in the late detached stage and of the lateral-widespread type based on the site of the focal lesion. The intraoperative ICRS-OCD classification was stage III. We aimed to preserve and fix the lateral wall fragment with cancellous bone grafting if the condition of the articular cartilage was good and the size and thickness of the segment could withstand fixation. Results Bone union of the lateral wall fragment was achieved in all cases. The elbow extension range of motion was −3.9° ± 9.7° before surgery and was eventually −0.4° ± 6.7° at the final assessment. Flexion range of motion ranged from 138.1° ± 10.5° to 142.4° ± 6.2°. The Timmerman and Andrews score significantly improved from 165.5 ± 10.9 points before surgery to 197.0 ± 6.3 points after surgery, demonstrating excellent results in all patients. All patients were able to return to competitive baseball. Conclusion The radiographic and clinical outcomes of FFBP for lateral wall fragments with cancellous bone graft were satisfactory, showing that the indications for this procedure could be extended to ICRS-OCD stage III.

Abstract
AIMS The hypothesis of this study was that bone peg fixation in the treatment of osteochondral lesions of the talus would show satisfactory clinical and radiological results, without complications. METHODS Between September 2014 and July 2017, 25 patients with symptomatic osteochondritis of the talus and an osteochondral fragment, who were treated using bone peg fixation, were analyzed retrospectively. All were available for complete follow-up at a mean 22 of months (12 to 35). There were 15 males and ten females with a mean age of 19.6 years (11 to 34). The clinical results were evaluated using a visual analogue scale (VAS) and the American Orthopaedic Foot and Ankle Society (AOFAS) score preoperatively and at the final follow-up. The radiological results were evaluated using classification described by Hepple et al based on the MRI findings, the location of the lesion, the size of the osteochondral fragment, and the postoperative healing of the lesion. RESULTS The mean VAS and AOFAS score improved significantly from 6.3 (4 to 8) and 70.6 (44 to 78) preoperatively to 1.6 (0 to 5) and 91.1 (77 to 100) at the final follow-up, respectively (p < 0.001). The classification on MRI was stage 2a in nine patients, stage 3 in 14, and stage 4 in two. The lesion was located on the posteromedial aspect of the dome of the talus in 19 patients, the anterolateral aspect in five, and the centrolateral aspect in one. The mean size of the fragment was 11.2 mm (5 to 20) horizontally, 10.4 mm (7 to 18) vertically, and 5.2 mm (3 to 10) deep, respectively. The postoperative healing state was good in 19 patients and fair in six. CONCLUSION Bone peg fixation for osteochondral lesions of the talus showed satisfactory clinical and radiographic results, without complications. This technique could be a good form of treatment for patients with this condition who have an osteochondral fragment. Cite this article: Bone Joint J 2020;102-B(10):1349-1353.

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
Background Even in patients with an open capitellar physis, nonsurgical treatment for advanced-stage osteochondritis dissecans (OCD) of the capitellum often yields poor outcomes. However, surgical methods for such patients are controversial. At our institution, we have consistently performed closed-wedge osteotomy of the distal humerus to treat advanced-stage OCD of the capitellum, regardless of the OCD grade or condition of the capitellar physis. Purpose To clarify the clinical and radiological results and determine the influence of the capitellar physis on closed-wedge osteotomy for advanced-stage OCD of the capitellum in young patients. Study Design Case series; Level of evidence, 4. Methods A total of 32 patients with OCD of the humeral capitellum were treated surgically with closed-wedge osteotomy. Of these, 17 patients with more than 2-year follow-up were available for an evaluation. The mean patient age was 11.8 years (range, 11-12 years), and the mean follow-up period was 70.1 months (range, 25-184 months). The clinical assessment included range of motion, elbow pain, and the Japanese Orthopaedic Association (JOA) and Timmerman-Andrews scores. The radiological assessment at the final examination included cross-bridging of the physis, size and fishtail deformity of the distal part of the humerus, size of the radial head, healing of the OCD lesion, and osteoarthritis. Results The mean range of motion and JOA and Timmerman-Andrews scores improved significantly after surgery; 13 patients were completely pain free. In 11 patients with an open capitellar physis, metaphyseal-epiphyseal, cross-bridging was observed in 1 patient. A fishtail deformity of the distal part of the humerus was not observed. Healing of the OCD lesion was defined as excellent in 9 patients, good in 3, fair in 3, and poor in 2. In 3 of the 5 patients in whom healing was described as fair or poor, there was a lesion of the lateral widespread type with osteoarthritis before surgery. Moderate osteoarthritic changes were evident in 2 patients. Conclusion Closed-wedge osteotomy for the treatment of advanced-stage OCD of the capitellum in young patients can provide satisfactory clinical and radiological results. However, fair and poor outcomes were found in lateral widespread-type cases with osteoarthritis before surgery. We believe that patients in whom osteoarthritic changes have not yet appeared are eligible for closed-wedge osteotomy.

Abstract
BACKGROUND Osteochondral autograft transplantation (OAT) for capitellar osteochondritis dissecans (OCD) requires harvesting of tissue from the asymptomatic knee joint. However, donor site morbidity (DSM) in such cases remains unclear. PURPOSE To evaluate DSM and postoperative radiographic findings in patients undergoing OAT for advanced capitellar OCD. STUDY DESIGN Case series; Level of evidence, 4. METHODS Eighty-six juvenile athletes underwent OAT for advanced capitellar OCD. The 2000 International Knee Documentation Committee subjective score, rate of return to sports, and symptoms in the donor knee were assessed at a mean follow-up of 86 months (range, 28-185 months). Additionally, 49 of the 86 patients were assessed by radiographic and magnetic resonance imaging (MRI) findings of the knee donor site. DSM was defined according to the usual criterion (persistent symptoms for >1 year or the need for subsequent intervention) and a stricter criterion (the presence of any symptoms, such as effusion, patellofemoral complaints, crepitation, unspecified disturbance, stiffness, pain/instability during activities, and osteoarthritic change). The stricter criterion was also used to allocate patients into a DSM group and a no-DSM group. RESULTS Two and 11 patients were determined to have DSM according to the usual and stricter criteria, respectively. All patients returned to the competitive level of their sports. The mean International Knee Documentation Committee score was 99.0. MRI findings showed abnormal signal intensity in 17 patients (35%) and hypertrophic changes in 11 patients (22%) at the donor harvest sites. The MOCART (magnetic resonance observation of cartilage repair tissue) score was higher in the no-DSM group (mean, 68.2) than in the DSM group (mean, 52.9) (P = .027). CONCLUSION OAT for juvenile athletes with advanced capitellar OCD provided good clinical outcomes. The DSM rate was relatively low (2.3%) with the usual criterion but high (12.8%) with the stricter criterion. MRI showed an abnormal signal intensity and hypertrophy in some cases.

Abstract
PURPOSE The primary outcomes are the evaluation and quantification of pain relief and improvement in range of motion after OAT in OCD. The secondary outcomes are: resuming of sport activities, evaluation of the ADL recovery rate and subjective evaluation of the quality of life improvement. METHODS Nine patients, affected by an unstable and non-acute OCD lesion of the capitulum humeri, have been treated by the same surgeon. The patient mean age was 22.4 (16-45 years). All subjects were treated with the same surgical technique (arthroscopic OAT from the same side knee, a single cylinder of 6.5-9 mm in diameter) and underwent the same rehabilitation. The mean follow-up was 48 months (30-52 months). The authors documented the clinical assessment of each patient and carried out a questionnaire which included the VAS scale, MEPS Score and Quick DASH score. Patients were asked for MRI and radiographs pre- and post-operatively at follow-up. RESULTS The mean range of motion improvement was 17.9° in extension (range 13°-27°) and 10.6° in flexion (range 0°-20°) The VAS mean improvement was 7.1 (range 6-8) and the mean post-op value 0.6 (range 0-3). The MEPS score mean post-operative value was 98.3 (range 85-100). The Quick-DASH mean post-operative value was 2.5 (range 0-9.1) with a mean improvement of 41.4 points (range 36.4-47.7 points). All patients resumed sports in 6 months post-operatively. CONCLUSIONS The autologous transplant of an osteochondral plug is a safe and promising procedure. Despite being more demanding, the arthroscopic approach is a valuable tool if the surgeon aims to reduce the invasiveness of the procedure, with all the consequent advantages. LEVEL OF EVIDENCE IV Retrospective case series, therapeutic study.

Abstract
PURPOSE OF THE REVIEW To review the most recent literature on osteochondritis dissecans (OCD) lesions of the capitellum in overhead athletes and describe a treatment algorithm based on current best evidence and surgeon experience. RECENT FINDINGS Recent research has included larger cohort studies with longer follow-up as well as quality systematic reviews and meta-analyses. These studies have focused on understanding how lesion characteristics such as size, location, and appearance on advanced imaging can predict treatment success. Current literature continues to support nonoperative management for stable lesions. Operative intervention is generally required for unstable lesions and treatment strategies are largely dictated by lesion size and location: debridement or reparative techniques for small lesions while larger lesions or those in high-stress locations are better served by bone and/or cartilage restoration procedures. There has been a rising interest in the use of allograft materials and cell-based therapies. Overhead athletes are uniquely predisposed to capitellar OCD due to the nature of forces applied to the radiocapitellar joint during repeated activity in the overhead position. Despite improvements in operative techniques, successful use of alternative graft materials, and a better understanding of how lesion characteristics influence results, there is still much to learn about this challenging disorder. Future research should focus on comparing operative techniques, refining their indications, and further developing a reliable treatment algorithm that best serves the overhead athlete.

Abstract
INTRODUCTION The osteochondral fracture of the talus is an uncommon condition, therefore, there are controversies for the optimal treatment. We report a novel surgical technique of bone peg fixation for osteochondral fracture of the talus. MATERIALS AND METHODS We report two cases that underwent bone peg fixation for the acute osteochondral fractures of talus. Clinical and radiographic evaluations were performed at the last follow-up. RESULTS At the last follow-up, mean ROM of ankle joint was 50° (range 45°-55°). Additionally, mean VAS and AOFAS score were 0 and 100 at the last follow-up, respectively. All patients obtained bone union without complication at the last follow-up radiographs. CONCLUSIONS This case study shows good clinical and radiographic results with autologous bone peg fixation in patients with acute osteochondral fractures of the talus. LEVEL OF EVIDENCE V, expert opinion.

Outcomes of surgical treatment for osteochondritis dissecans of the elbow: evaluation by lesion location. J Shoulder Elbow Surg 2018; 27:2262-2270. [PMID: 30446232 DOI: 10.1016/j.jse.2018.08.011] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2018] [Revised: 08/05/2018] [Accepted: 08/11/2018] [Indexed: 02/01/2023]
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 Autologous osteochondral mosaicplasty (ie, mosaicplasty) results in satisfactory clinical outcomes and reliable return to play for patients with large or unstable lesions due to osteochondritis dissecans (OCD) of the humeral capitellum. However, the association between the healing of the reconstructed cartilage and clinical outcomes remains unclear. PURPOSE To evaluate the efficacy of mosaicplasty in teenage athletes through use of clinical scores and imaging. The secondary purpose was to compare the clinical outcomes with images of centrally and laterally located lesions. STUDY DESIGN Case series; Level of evidence, 4. METHODS This study analyzed 22 elbows (all male patients; mean age, 13.5 ± 1.2 years) with capitellar OCD managed with mosaicplasty. Patients were divided into 2 groups according to the location of the lesions: central (10 patients) and lateral (12 patients). Evaluation was performed through use of the clinical rating system of Timmerman and Andrews, plain radiographs, and magnetic resonance imaging (MRI; the cartilage repair monitoring system of Roberts). The mean follow-up period was 27.5 months (range, 24-48 months). RESULTS Lateral lesions were significantly larger than central lesions (147.1 ± 51.9 mm2 vs 95.5 ± 27.4 mm2, P = .01). No other significant differences were found between central and lateral lesions. Timmerman and Andrews scores for both central and lateral lesions improved significantly from 125.0 ± 30.1 points and 138.3 ± 34.5 points preoperatively to 193.5 ± 11.3 points and 186.7 ± 18.1 points, respectively, at final follow-up ( P < .0001, P < .0001). Radiography identified complete graft incorporation in all cases and the absence of severe osteoarthritic changes or displaced osteochondral fragments. In the lateral group, the radial head ratio at final follow-up (1.83 ± 0.23) was significantly larger than the preoperative findings (1.75 ± 0.14, P = .049). The quality of joint surface reconstruction was found to be acceptable for central and lateral lesions on MRI evaluation. CONCLUSION Mosaicplasty resulted in satisfactory clinical outcomes and smooth cartilage surface integrity in teenage athletes with OCD on their return to competition-level sports activities irrespective of lesion location.

Abstract
Background Capitellar osteochondritis dissecans (OCD) is a focal injury of the articular cartilage involving separation of a segment of cartilage from the subchondral bone that is infrequently encountered in the dominant-side elbow of adolescent throwing athletes1,2. The literature suggests that patients may achieve better short and mid-term results when treated with certain types of surgical procedures3,4. Selection of the appropriate surgical method should be based on the International Cartilage Repair Society (ICRS) OCD classification system5. For lesions involving ≤50% of the surface area of the capitellum, debridement with microfracture and/or loose body removal have shown excellent results. For lesions involving >50% of the surface area of the capitellum and classified as ICRS OCD III or IV, autologous osteochondral grafting may be the most suitable treatment6-8. Bone peg grafting (BPG) has been shown to be an effective treatment option for early-stage capitellar OCD that can preserve the local hyaline cartilage9,10. Description Using direct vision and with arthroscopy, the continuity of the capitellar surface and the stability of the capitellar lesion were evaluated according to the ICRS OCD classification5. BPG was indicated for adolescents with ICRS OCD I or II. The elbow was opened between the extensor carpi ulnaris and the anconeus muscle (Kocher interval). Another skin incision of 3 cm in length was made at the posterior aspect of the metaphysis of the ipsilateral olecranon. Three, 4, or 5 bone pegs of approximately 20 mm in length were harvested from the posterior ulnar cortex. A Kirschner wire of 3 mm in diameter was used for drilling holes in the lesion, and then the bone pegs were inserted with tweezers to a depth of 10 mm. Next, a flat-surfaced rod was placed on the head of each bone peg to press it to a depth slightly lower than the articular cartilage surface. Postoperatively, the elbow was immobilized for 3 weeks. Throwing was allowed at 6 months, and a return to competitive baseball at preinjury levels was permitted at 8 months after BPG. Alternatives Arthroscopic debridement of the lesion.Arthroscopic bone marrow stimulation or microfracture.Fragment fixation using metal implants or biodegradable materials.Use of autologous osteochondral graft from the distal aspect of the femur or from a rib. Rationale Our follow-up study after BPG revealed that 10 of 11 patients with ICRS OCD I or II capitellar OCD could return to their preinjury baseball ability and that 8 of the 11 lesions completely healed as seen radiographically11. Radiographic and magnetic resonance imaging (MRI) findings showed that BPG could secure the lesion to the osseous floor as a physiological scaffold. Fragment fixation with metal implants or biodegradable materials carries a risk of damaging cartilage surfaces, and autologous osteochondral grafting is too invasive for this early-stage lesion. BPG is indicated for ICRS OCD I or II lesions, especially with central positioning and/or occupying <75% of the size of the capitellum in the coronal plane11.

Abstract
Osteochondritis dissecans (OCD) of the humeral capitellum is a critical elbow injury in adolescent overhead throwing athletes. However, its etiology remains unknown. Medical examinations using ultrasonography found that the prevalence of capitellar OCD among adolescent baseball players was approximately from 1% to 3%. A plain anteroposterior radiograph with the elbow in 45° of flexion is essential for the diagnosis of an OCD lesion. The stability of OCD lesions is evaluated on plain radiographs, computed tomography, and magnetic resonance imaging (MRI). Imaging features of the unstable lesions are an epiphyseal closure of the capitellum or a lateral epicondyle, a displaced fragment, or irregular contours of the articular surface and a high signal interface on T2-weighted MRI. A stable lesion has the potential to be healed with conservative treatment. By contrast, surgical treatment should be considered if there is no radiographic improvement within 3 months. In addition, surgery should be performed for the lesions that cause pain during daily activities, have a locking phenomenon, or which are assessed by imaging as obviously unstable. Arthroscopic debridement/loose body removal can be performed for small lesions (≤12 mm in diameter). For large lesions (>12 mm), preservation and/or reconstruction of the articular surface should be selected, such as bone-peg fixation of the lateral part of the fragment and osteochondral autograft transplantation (OAT) from the knee. In the future directions, there is no comparative study of OAT from the knee and rib. In addition, little is known about its long-term outcome, or resulting osteoarthritis. A recent meta-analysis showed that grafts harvested from the knee may lead to donor site morbidity (7.8%). Thus, a novel cartilage tissue engineering approach is anticipated.

Abstract
PURPOSE OF REVIEW With an increasing rate of adolescent elbow injuries, especially in throwing athletes, the purpose of this review is to investigate the current literature regarding the diagnosis, treatment, and non-operative and operative outcomes of medial epicondyle fractures, ulnar collateral ligament repair, osteochondritis dissecans of the elbow, and olecranon stress fractures. RECENT FINDINGS Acceptable outcomes with both non-operative and operative treatments of medial epicondyle fractures have been reported, with surgical indications continuing to evolve. Unstable osteochondritis dissecans lesions, especially in patients with closed growth plates, require operative fixation, and emerging open and arthroscopic techniques including lesion debridement, marrow stimulation, autograft transfer, and allograft transplantation are described with good outcomes. Ulnar collateral repair has emerged as an exciting treatment option for an avulsion of either end of the ligament in young throwing athletes, with faster rehabilitation times than traditional ulnar collateral ligament reconstruction. Olecranon stress fractures are increasing in prevalence, and when a non-operative treatment course is unsuccessful, athletes have a high return-to-play rate after percutaneous cannulated screw placement. With proper indications, non-operative and operative treatment modalities are reported with a high return-to-play and acceptable clinical outcomes for common elbow injuries, including medial epicondyle fractures, ulnar collateral ligament repair, osteochondritis dissecans of the elbow, and olecranon stress fractures, in adolescent throwing athletes. Further research is needed to better define treatment algorithms, surgical indications, and outcomes.

Abstract
BACKGROUND Clinical studies have reported satisfactory results after osteochondral autograft transplantation (OAT) for central lesions of unstable osteochondritis dissecans (OCD) of the elbow. However, the outcomes after OAT for lateral lesions remain unclear. HYPOTHESIS The clinical outcomes of OAT would be better for central lesions than for lateral lesions. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS The authors retrospectively evaluated 103 juvenile athletes (mean age, 13.2 years; range, 11-16 years) who underwent OAT for symptomatic OCD of the humeral capitellum from 2003 to 2014. Sixteen patients were excluded because they did not fit the inclusion criteria. The final cohort of 87 patients was divided by lesion type into central lesion (n = 43) and lateral lesion (n = 44) groups. When possible, a single large plug was created for grafting and trimmed to reconstruct the rounded joint surface. The clinical, radiographic, and magnetic resonance imaging outcomes were evaluated for each group at a mean follow-up of 43 months (range, 24-100 months). RESULTS There were no significant differences in the age, sex, height, weight, duration of symptoms, follow-up time, preoperative range of motion, or Timmerman and Andrews score between the 2 groups. The preoperative osteoarthritic changes (0 of 43 for central vs 5 of 44 cases for lateral; P = .023), mean lesion size (12.2 ± 2.9 vs 18.2 ± 7.0 mm; P < .001), and graft number (1.6 vs 2.8; P < .001) were significantly greater in the lateral group versus the central group. The mean range of extension (2.3° ± 5.4° vs -3.2° ± 8.7°; P < .001) and Timmerman and Andrews score (194 vs 185; P = .006) at the final follow-up were significantly better for patients in the central group. More patients in the lateral group had postoperative radial head subluxation (0 of 43 vs 6 of 44; P = .012) and osteoarthritic changes (1 of 43 vs 9 of 44; P = .008). The mean MOCART score showed no significant differences between the groups (78.0 ± 15.7 vs 72.6 ± 20.9; P = .181). The rate of return to sports at the previous level was 100% in the central group and 86% in the lateral group ( P = .012). CONCLUSION The clinical and radiographic outcomes after OAT associated with unstable OCD of the humeral capitellum were better for central lesions than for lateral lesions. However, satisfactory outcomes and a high rate of return to sports were obtained for unstable lateral lesions after OAT.
