RESUMEN
Osteochondral lesion of the talus (OLT) is a localized cartilage and subchondral bone injury of the talus trochlea. OLT is caused by trauma and other reasons, including osteochondritis dissecans of the talus (OCD) and talus osteochondral tangential fracture. OLT can develop from being asymptomatic to subchondral bone cysts accompanied by deep ankle pain. OLT tends to occur on the medial and lateral sides of the talar vault. OLT seriously affects the patients' life and work and may even lead to disability. Herein, we reviewed advances in the treatment of OLT and the strengths and weaknesses of various treatments. Different treatment methods, including conservative treatments and surgical treatments, can be adopted according to the different subtypes or clinical symptoms of OLT. Conservative treatments mostly relieve symptoms in the short term and only slow down the disease. In recent years, it has been discovered that platelet-rich plasma injection, microfracture, periosteal bone grafting, talar cartilage transplantation, allograft bone transplantation, reverse drilling under robotic navigation, and other methods can achieve considerable benefits when each of these treatment methods is applied. Furthermore, microfracture combined with platelet-rich plasma injections, microfracture combined with cartilage transplantation, and various other treatment methods combined with anterior talofibular ligament repair have all led to good treatment outcomes.

Osteochondritis dissecans (OCD) of the knee is a potentially disabling condition in adolescent and young adults, which is likely multifactorial in origin. In recent years, there have been notable improvements in identification and treatment. Clinical presentation varies based mostly on OCD lesion stability. Patients with stable lesions generally present with vague knee pain and altered gait while mechanical symptoms and effusion are more common with unstable lesions. Lesions most commonly occur on the lateral aspect of the medial femoral condyle in patients aged 10 to 20 years. Magnetic resonance imaging is vital to diagnose and predict clinical treatment, which is largely based on stability of the fragment. Conservative treatment of stable lesions in patients with open physis is recommended with protected weight-bearing and gradual progression of activities over the course of 3 to 6 months. Stable OCD lesions which failed a nonsurgical course can be treated with transarticular or retrograde drilling while unstable lesions usually require fixation, autologous chondrocyte implantation (ACI), osteochondral autograft transfer (OATS), or osteochondral allograft transplantation. This review highlights the most current understanding of knee OCD lesions and treatment options with the goal of optimizing outcomes in this difficult pathology.

PURPOSE: To perform a scoping review to identify the available evidence regarding osteochondritis dissecans (OCD) of the temporomandibular joint (TMJ). METHODS: An electronic search of the PubMed, Web of Science and Scopus databases was performed using the following terms: 'Temporomandibular Joint Disorders', 'Osteochondritis Dissecans', 'Joint Loose Bodies' and 'Temporomandibular Joint'. Full-text articles were obtained from the records after applying the inclusion/exclusion criteria. RESULTS: Ten articles were included in the analysis - six case reports, one case series, one retrospective study, one comparative study and one correlational study - with a total of 39 patients. The most frequently reported clinical presentation involved TMJ pain, locked jaw and articular noises (clicking and crepitus). The imaging methods used to identify OCD were radiographs, tomography, arthrography and magnetic resonance imaging. The reported imaging findings varied widely, but the most frequent were (single or multiple) calcified intra-articular loose bodies, signs of degenerative osseous changes, disc displacements, widening of the joint space and alterations in condylar morphology. Seven articles reported treatments (surgical or conservative), but the treatment outcome was not reported in all of the articles, which makes it difficult to make comparisons. CONCLUSION: OCD of the TMJ may present various non-specific clinical characteristics, and given the heterogeneous imaging findings, multiplanar images are required for an accurate diagnosis. Finally, the results do not allow recommending a standard treatment for OCD of the TMJ.

OBJECTIVE: Previous research on patellar and trochlear groove osteochondritis dissecans (OCD) is limited by small sample sizes. This study aims to describe the presentation of patients with OCD lesions of the patella and trochlea and characterize the outcomes of operative and nonoperative treatments. METHODS: This retrospective cohort study identified all patients from a single institution from 2008 to 2021 with patellar and/or trochlear OCD lesions. Patients were excluded from the study if surgical records were unavailable or if the patient had knee surgery for a different injury at index surgery or in the 12 months postoperative. Minimum follow-up was 12 months. Outcomes included a return to sports (RTS), pain resolution, radiographic healing, and treatment "success" (defined as full RTS, complete pain resolution, and full healing on imaging). RESULTS: A total of 68 patients (75 knees) were included-45 (60%) with patellar OCD and 30 (40%) with trochlear. Of the patients, 69% were males. The median age at knee OCD diagnosis was 14 years. At the final follow-up, 62% of knees (n = 44) recovered sufficiently to allow a full RTS and 54% of knees (n = 39) had full pain resolution. Of the 46 knees with radiographic imaging at least 1 year apart, 63% had full healing of the lesion. There was no significant difference in RTS, pain resolution, radiographic healing, or overall success when comparing treatments. CONCLUSIONS: This study provides valuable epidemiologic demographic and outcome data regarding the scarcely reported patellar and trochlear OCD. While over half of patients fully returned to sports and reported full pain resolution, a large proportion continued to experience symptoms over a year after presentation. Future research should aim to better define the treatment algorithms for these OCD subtypes. LEVEL OF EVIDENCE: Level III.

Juvenile osteochondritis dissecans (JOCD) is a pediatric disease, which begins with an osteonecrotic lesion in the secondary ossification center which, over time, results in the separation of the necrotic fragment from the parent bone. JOCD predisposes to early-onset osteoarthritis. However, the knowledge gap in JOCD pathomechanisms severely limits current therapeutic strategies. To elucidate its etiology, we conducted a study with induced pluripotent stem cells (iPSCs) from JOCD and control patients. iPSCs from skin biopsies were differentiated to iMSCs (iPSC-derived mesenchymal stromal cells) and subjected to chondrogenic and endochondral ossification, and endoplasmic reticulum (ER)-stress induction assays. Our study, using 3 JOCD donors, showed that JOCD cells have lower chondrogenic capability and their endochondral ossification process differs from control cells; yet, JOCD- and control-cells accomplish osteogenesis of similar quality. Our findings show that endoplasmic reticulum stress sensing and response mechanisms in JOCD cells, which partially regulate chondrocyte and osteoblast differentiation, are related to these differences. We suggest that JOCD cells are more sensitive to ER stress than control cells, and in pathological microenvironments, such as microtrauma and micro-ischemia, JOCD pathogenesis pathways may be initiated. This study is the first, to the best of our knowledge, to realize the important role that resident cells and their differentiating counterparts play in JOCD and to put forth a novel etiological hypothesis that seeks to consolidate and explain previously postulated hypotheses. Furthermore, our results establish well-characterized JOCD-specific iPSC-derived in vitro models and identified potential targets which could be used to improve diagnostic tools and therapeutic strategies in JOCD.

Osteochondritis dissecans is a condition characterised by acquired pathological subchondral bone lesions and its incidence is unknown. It has a multifactorial aetiology, with a combination of genetic and acquired risk factors. It commonly presents in adolescents and young adults. Patients have variable presentations, including trauma, insidious onset and pain exacerbated by exercise. The joints primarily affected are the knee, ankle and elbow joint. Early identification is key to treatment and to prevent future osteoarthritis of the joint. This article gives an overview of the presentation, assessment and management of the juvenile form of osteochondritis dissecans.

We report the rate of stable femoral condyle osteochondritis dissecans (OCD) lesion healing in adolescents using a locked hinged knee brace for a minimum of 6 weeks or until pain free, followed by physical therapy. Patients aged 5-18 at the time of a primary diagnosis of femoral condyle OCD were reviewed. Patients who presented with an unstable lesion necessitating surgery, lacked follow-up >6 months after diagnosis or before symptoms resolution, or were noncompliant were excluded. We assessed progression to surgery, association between surgery and lesion size, lesion grade, symptoms, laterality, and patient factors. Lesion width and depth and condyle size were measured on X-ray and MRI, and the scaled size of the lesion relative to the condyle was calculated. Sixty-four patients were included: 12.5% (n = 8; 50% female; mean age = 12.5 ± 1.0 years) progressed to surgery and 87.5% (n = 56; 20% female; mean age=11.5 ± 1.9 years) healed. No significant effects were identified between groups. The surgical group compared to the non-surgical group was braced for a similar amount of time (72.6 ± 51.4 vs. 54.9 ± 23.2 days; P = 0.09), presented initially with a similar lesion size (322.5 ± 298.7 vs. 211.2 ± 178.4 mm2; P = 0.14), and had a similar proportion of Grade 1 lesions (63% vs. 85%; P = 0.11). Female sex (P = 0.04) and longer time in the brace (P = 0.04) were associated with progression to surgery.

PURPOSE: The purpose of the study was to evaluate the effect of skeletal age and lesion size, location, and grade on the success of nonoperative treatment for juvenile osteochondritis dissecans (OCD). It is hypothesized that skeletal maturity, including a combination of maturation phenotypes, correlates with nonoperative lesion healing. METHODS: The clinical and radiographic data on 52 patients aged 7-20 years treated for OCD of the distal femur between 2010 and 2019 were retrospectively reviewed. Knee radiographs were assessed for number of lesions present and lesion location, size, and stage. Assessments of skeletal maturation were performed on all antero-posterior knee radiographs using the Roche, Wainer, and Thissen (RWT) method. Patients were categorized as healed if they demonstrated no pain on clinical examination. The relationship between skeletal maturity and nonoperative lesion healing was determined using Spearman rank correlations on available variables. RESULTS: Neither chronological nor skeletal age was associated with surgical status (Rho = 0.03, n.s., and Rho = 0.13, n.s., respectively) or the healing status of nonoperatively treated OCD lesions (Rho = 0.44, n.s., and Rho = 0.03, n.s., respectively). Epiphyseal fusion status of the distal femoral physis was moderately correlated with nonoperative healing, but was not statistically significant (lateral femoral physis: Rho = 0.43, p = 0.05; medial femoral physis: Rho = 0.43, n.s.). Lesion length correlated with surgical status (Rho = - 0.38, p = 0.009). CONCLUSION: The extent of fusion of the distal femoral physis (multi-stage grading) may be more strongly correlated with nonoperative healing than other markers of skeletal maturity or chronological age. Clinicians can use this as an additional radiographic sign when considering nonoperative treatment for juvenile OCD lesions in the distal femur. OCD lesion length and physeal fusion status appear to be more important for healing than patient age.

INTRODUCTION: To report on the long-term prognosis of osteochondritis dissecans (OCD) patients regarding radiological and patient-reported outcomes and to analyze possible risk factors. MATERIALS AND METHODS: All patients diagnosed with knee OCD between 2004 and 2014 with radiographic Kellgren-Lawrence (K-L) grades 0-2 at the time of diagnoses, ability to understand the language of the interview, and willingness to participate in the study were retrospectively reviewed. Current knee radiographs and the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire were prospectively collected between May 2020 and March 2021. The extent of osteoarthritis (OA) and KOOS questionnaire results were evaluated. RESULTS: 90 patients (103 knees) with a mean age of 21 years (range 6-60) were included. The mean follow-up time was 12 years (range 7-20). 24 knees (23%) were treated conservatively, and 79 knees (77%) operatively. At the time of diagnoses, 90% of the patients had K-L grades of 0-1; during the follow-up period, 45% of the patients showed radiological progression of OA. Patient body mass index (BMI) (p = 0.004; 95% CI 0.25-0.29), age (p = 0.003; 95% CI 0.18-0.30), operative treatment (p = 0.0075; 95% CI 0.41-0.65) and lesion depth (p = 0.0007) were statistically significantly connected to K-L grade change. Patients with no progression in joint space narrowing had statistically significantly better overall KOOS scores (p = 0.03; 95% CI 0.77-0.88) than patients whose K-L grades worsened. CONCLUSIONS: During the long-term follow-up of 12 years, patients with knee OCD had good clinical results. Lac of radiological progression of cartilage degeneration was noted in 55% of the patients, regardless of treatment method. Lesion depth, higher BMI and older age were associated with the progression of OA. The progression of OA was related to a worsening of functional scores. LEVEL OF EVIDENCE: IV.

OBJECTIVE: To investigate the healing response of juvenile osteochondritis dissecans (JOCD) of the talus after conservative treatment, identify healing predictors, and develop a predictive model for healing. DESIGN: Retrospective study. SETTING: Clinics at a tertiary-level pediatric medical center. PATIENTS: Fifty-five patients (55 ankles) who presented with JOCD. INTERVENTIONS: Patients were managed with cast immobilization followed by activity restriction. MAIN OUTCOME MEASURES: The primary outcome measure of progressive lesion reossification was determined from the latest radiograph, after at least 6 months of nonoperative treatment. Final clinical evaluation was performed by a questionnaire and complementary telephone interview. Multivariate logistic regression was used to determine the influence of age, sex, lesion size, classification, location, duration of symptoms, containment lesion, and the occurrence of cyst-like lesions on healing potential. RESULTS: After nonoperative treatment, 18 (33%) of 55 lesions had failed to progress toward healing. An older age (P = 0.034) and a completely detached but undisplaced (grade III) lesion (P < 0.001) at the time of diagnosis were predictive for the failure of conservative treatment. A multivariate logistic regression best predictor model that included age and grade resulted in the best predicted healing and yielded an area under the curve of 0.920 (P < 0.001). CONCLUSION: In two-thirds of skeletally immature patients, conservative treatment resulted in the progressive healing of JOCD of the talus. For older patients with grade III lesions showing a lower healing probability, surgical treatment should be considered.

Osteochondritis dissecans of the knee is a relatively rare disorder in young athletes that can lead to premature osteoarthritis. It may be caused by multiple factors, including repetitive stress, local ischemia, aberrant endochondral ossification of the subarticular physis, and hereditary disposition. Nonoperative treatment is typically attempted for patients with open physes, stable lesions, and minimal symptoms. Operative treatment is offered to patients with closed physes, unstable lesions, mechanical symptoms, and failure of nonoperative treatment. Customized rehabilitation and return to sport programs are important for successful outcomes regardless of treatment type.

BACKGROUND: This study aimed to compare the healing outcomes of conservative treatment for osteochondritis dissecans (OCD) of the lateral femoral condyle with normal lateral meniscus and incomplete discoid lateral meniscus (DLM). METHODS: Forty-four knees in 37 juvenile patients (mean age 9.9 y) with stable OCD and whose lateral meniscus shape was normal or incomplete DLM were enrolled. All patients underwent conservative treatment with physical activities prohibited. For each lateral meniscus group, patient demographics including pretreatment Tegner activity scale, OCD stage, and Lysholm score, radiographic healing status; complete or incomplete healing at 3 months, 6 months, and 1 year, time to complete healing and post-treatment clinical scores were evaluated. RESULTS: There were 21 (47.8%) and 23 (52.3%) knees with normal menisci and incomplete DLM, respectively. At 3 months, 6 months, and 1 year after conservative treatment, healed OCD status was noted in 3 (14.3%), 12 (57.1%), and 19 (90.5%) knees of the normal type and in 3 (13.0%), 12 (52.2%), and 20 (86.9%) knees of the incomplete DLM type, respectively (P>0.05). The mean time to healing in each group was 198 and 181 days, respectively. No significant differences in terms of OCD healing rate at each time, time to healing, and post-treatment clinical scores were found between the groups. CONCLUSION: No significant differences in the OCD healing rate or time to healing were found between the normal and incomplete DLM type. Therefore, treatment strategy for OCD with stable and asymptomatic incomplete DLM should be the same as that for those occurring with a normal meniscus.

BACKGROUND AND HYPOTHESIS: Stable lesions of osteochondritis dissecans (OCD) of the capitellum have been treated with activity restriction (AR), and the complete healing requires 1 or 2 years. Little is known about the effectiveness of elbow immobilization. We hypothesized that elbow immobilization would have positive effects on healing of stable OCD. METHODS: The study subjects were 43 patients (mean age: 12.2 years) with 43 stable OCD lesions of the prematured elbow (mean skeletal age score: 17.1 points of 0-27 points system). The subjects were divided into 3 groups: group A, AR without elbow immobilization, 22 cases; group B, splint (mean: 8.8 weeks) followed by AR, 9 cases; and group C, cast (mean: 3.7 weeks) followed by splint (mean: 7.3 weeks) and AR, 12 cases. The mean nonoperative observation period was 17.5 months (minimum three months). On anteroposterior radiographs of the elbow at 45 degrees of flexion, 5 observers independently assessed the healing of the capitellum, and the interobserver and intraobserver reliabilities were examined. The differences in outcomes among 3 groups were also examined. RESULTS: The interobserver and intraobserver reliabilities of the radiographic assessment were almost perfect (Cohen kappa value: 0.82 and 0.91, respectively). There were no significant differences in age, sports played, or stage of the lesion before the treatment. The proportion of patients returning to sports and the mean period required were 77% and 8.2 months in group A, 78% and 5.7 months in group B, and 83% and 4.4 months in group C, respectively. The proportion of patients showing ossification in the central aspect of the capitellum and the mean period required were 67% and 8.2 months in group A, 63% and 4.9 months in group B, and 91% and 1.9 months in group C, respectively. The proportion of patients showing complete healing and the mean period required were 41% and 16.4 months in group A, 67% and 7.0 months in group B, and 92% and 5.5 months in group C, respectively. Compared to group A, group C showed a significantly earlier return to sports (P = .034), a significantly shorter period required for ossification (P < .001), and significantly higher proportion of patients with complete healing (P = .012) within a significantly shorter period (P = .009). CONCLUSION: Elbow immobilization had positive effects on healing and enabled both an early return to sports and complete healing. Cast immobilization is recommended as a first choice of nonoperative treatment for stable OCD lesions of the elbow before epiphyseal closure.

â¤: 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. â¤: 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. â¤: 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. â¤: 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. â¤: 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.

BACKGROUND: Radial head stress fractures (RHSFs) and capitellar osteochondritis dissecans (COCD) are rare but may be seen in gymnasts. The purpose of this study was to compare the clinical and radiographic characteristics and the outcomes of RHSF and COCD in pediatric and adolescent gymnastic athletes. METHODS: Classical gymnasts and competitive tumblers ≤18 years of age presenting with RHSF or COCD over a 5-year period were reviewed. Radiographic characteristics, clinical characteristics, and patient-reported outcomes were compared. RESULTS: Fifty-eight elbows (39 with COCD and 19 with RHSF) were studied; the mean patient age was 11.6 years. Gymnastic athletes with RHSF competed at a higher level; of the athletes who competed at level ≥7, the rate was 95% of elbows in the RHSF group and 67% of elbows in the COCD group. The RHSF group presented more acutely with more valgus stress pain than those with COCD (p < 0.01) and demonstrated increased mean valgus angulation (and standard deviation) of the radial neck-shaft angle (13° ± 3.8° for the RHSF group and 9.3° ± 2.8° for the COCD group; p < 0.01) and decreased mean proximal radial epiphyseal height (3.7 ± 0.6 mm for the RHSF group and 4.2 ± 1.5 mm for the COCD group; p < 0.01). At a minimum of 2 years (range, 2.0 to 6.3 years), the RHSF group reported fewer symptoms; the QuickDASH (abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire) score was 1.75 ± 3.84 points for the RHSF group and 7.45 ± 7.54 points for the COCD group (p < 0.01). Those at a high level (≥7) were more likely to return to gymnastics independent of pathology, with the RHSF group reporting higher final activity levels with the mean Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS) score at 26.0 ± 7.5 points compared with the COCD group at 23.6 ± 5.7 points (p < 0.05). Of the 9 patients with bilateral COCD, only 3 (33%) returned to gymnastics. CONCLUSIONS: RHSF with features similar to the more familiar COCD lesion may present in gymnastic athletes. Those with RHSF may present more acutely with a high competitive level and may have a better prognosis for return to competitive gymnastics than those with COCD. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

The purpose of this study was to evaluate the effect of race, insurance status, and socioeconomic status on successful or unsuccessful healing of osteochondritis dissecans (OCD) lesions in the pediatric knee. The authors retrospectively reviewed patients younger than 18 years who were treated for a knee OCD lesion between 2006 and 2017. Patients were required to have at least 6 months of clinical and radiographic follow-up to be included, unless complete healing was achieved sooner. The primary outcome of interest was healing of the OCD lesion based on radiographic and clinical examination. A total of 204 OCD lesions in 196 patients with a mean follow-up of 15.8±6.4 months were included. The mean age at initial presentation was 12.4±2.8 years. At most recent follow-up, 28 (13.7%) lesions did not show radiographic or clinical evidence of healing. Nonhealing lesions were found in 25.0% of Black children compared with 9.4% of White children (P=.02). After controlling for age, sex, sports participation, lesion size and stability, skeletal maturity, and operative vs nonoperative treatment in a multivariate model, Black children had 6.7 times higher odds of unsuccessful healing compared with their White counterparts (95% CI, 1.1-41.7; P=.04). In this study, Black children with OCD of the knee were significantly less likely to heal than were White patients, even when controlling for numerous other factors in a multivariate model. Although the exact etiology of this finding is unclear, future work should focus on the social, economic, and cultural factors that may lead to disparate outcomes.

Osteochondral defect or osteochondritis dissecans (OCD) of the knee usually affects young, active populations. It is a challenging diagnosis as patients typically present with poorly localised activity-related pain, which is non-specific and covers many differentials. We present an active 11-year-old girl with bilateral osteochondral defects of the patellae: a rare clinical disorder which was affecting her sporting activities. She had a 12-month history of bilateral anterior knee pain before the diagnosis was achieved with appropriate imaging. Her pain significantly improved with activity modification and physiotherapy. Follow-up will require outpatient clinic assessment and imaging to determine if non-operative management continues to be successful or surgery may be required. This case report emphasises the importance of appropriate high index of suspicion when managing patients with non-specific knee pain. It also demonstrates the importance of judicious use of imaging to avoid a missed or delayed diagnosis.

This is a review on talus osteochondritis dissecans and talus osteochondral lesions. A majority of the osteochondral lesions are associated with trauma while the cause of pure osteochondritis dissecans is still much discussed with a possible cause being repetitive microtraumas associated with vascular disturbances causing subchondral bone necrosis and disability. Symptomatic nondisplaced osteochondral lesions can often be treated conservatively in children and adolescents while such treatment is less successful in adults. Surgical treatment is indicated when there is an unstable cartilage fragment. There are a large number of different operative technique options with no number one technique to be recommended. Most techniques have been presented in level II to IV studies with a low number of patients with short follow ups and few randomized comparisons exist. The actual situation in treating osteochondral lesions in the ankle is presented and discussed.

PURPOSE OF REVIEW: The purpose of this review is to update the reader on the controversial subject of osteochondritis dissecans (OCD) with a focus on nonoperative treatment indications, methods, and success rate. RECENT FINDINGS: Work by an international multicenter study group ROCK (Research in OsteoChondritis of the Knee) will be reviewed including new classifications systems of healing, arthroscopy, radiographs, and MRI, along with new evidence on off-loading bracing compared to restricted weight bearing. SUMMARY: The paucity of evidence behind OCD treatment of the knee can lead to confusion for doctors, patients, and parents. The present review will bring more clarity to the subject.
