Osteochondritis dissecans (OCD) is an acquired idiopathic lesion of subchondral bone that can produce delamination and sequestration with or without articular cartilage involvement and instability. The cause of OCD is still debated: the most recognized etiology is the occurrence of repetitive micro-traumas associated with vascular impairment, causing progressive ankle pain and dysfunction in skeletally immature and young adult patients. Ankle OCD is classically located in the medial part of the talus, while lateral and posterior involvement is less frequent. Diagnosis of OCD, based on MRI findings, is quite straightforward; MRI examination can also be very useful for dating the defect and obtaining information about the associated bone bruise. Osteochondritis dissecans, if not recognized and treated appropriately, may lead to secondary osteoarthritis with pain and functional limitation. Surgical treatment is mandatory especially in young patients with unstable cartilage fragments. There are various surgical options: fixation, microfracture, or substitution using autologous chondrocyte implantation techniques.

Comparison of Glenoid Bone Loss After Unidirectional Versus Combined Shoulder Instability in a Military Population.
Orthop J Sports Med
January 2025
Department of Orthopaedic Surgery, Carthage Area Hospital, Carthage, New York, USA.
Background: While glenoid bone loss (GBL) after anterior shoulder instability correlates with poor functional outcomes, the specific effects of GBL in posterior and combined-type shoulder instability remain poorly characterized, especially in a high-risk military population.
Purpose/hypothesis: The purpose of this study was to compare GBL between unidirectional anterior or posterior instability versus combined-type instability in active-duty servicemembers. It was hypothesized that total GBL and GBL in the direction of instability would be greater in those with combined-type instability compared with unidirectional instability.
Functional Recovery and Clinical Outcome After Internal Fixation Using Osteochondral Autologous Transplantation for Osteochondritis Dissecans of the Knee.
Orthop J Sports Med
January 2025
Department of Orthopaedic Surgery, Hyogo Medical University, Nishinomiya, Hyogo, Japan.
Background: Functional recovery and return to sports after fixation of osteochondritis dissecans (OCD) lesions of the knee with osteochondral autologous transplantation (OAT) have not been well investigated.
Purpose: To retrospectively evaluate the functional recovery and clinical outcomes after internal fixation with OAT for knee OCD.
Study Design: Case series; Level of evidence, 4.
Morrey Award 2023: radial head donor plug for capitellum osteochondral autograft transfer: a cadaveric biomechanical analysis.
JSES Int
November 2024
Department of Orthopaedic Surgery, University of Iowa, Iowa City, IA, USA.
Background: Limitations to using the knee as donor cartilage include cartilage thickness mismatch and donor site morbidity. Using the radial head as donor autograft for capitellar lesions may allow for local graft harvest without distant donor site morbidity. The purpose of this study is to demonstrate the feasibility of performing local osteochondral autograft transfer from the nonarticular cartilaginous rim of the radial head to the capitellum.

Objectives: To compare the biomechanical strength and stiffness of the native posteromedial and posterolateral meniscotibial ligament complex (MTLC) to suture anchor repair of the MTLC.
Methods: Biomechanical testing was performed on 24 fresh-frozen pediatric human knees. Four conditions were tested: native posteromedial MTLC (n=14), native posterolateral MTLC (n=14), posteromedial MTLC repair (n=5), and posterolateral MTLC repair (n=5).
Return to Sport After Treatment of Stable Osteochondritis Dissecans Lesions of the Knee in Adolescents: A Systematic Review.
Am J Sports Med
January 2025
Rothman Orthopaedic Institute, Philadelphia, Pennsylvania, USA.
Background: Treatment of stable osteochondritis dissecans (OCD) lesions of the knee in young patients poses the challenge of abstaining from competitive sports for months. Outcomes relevant to this patient population additionally include successful return to sport (RTS), return to the same level of sport, and the time needed to achieve both.
Purpose: To evaluate the adolescent population for RTS outcomes after treatment of stable OCD lesions of the knee and to compare RTS outcomes between patients treated nonoperatively and those who required surgery.
