Osteochondral or, even more rarely, purely chondral fractures of the lateral femoral condyle following patella dislocation in adolescents are relatively infrequent. Various fixation methods are described in the literature, ranging from traditional screws to bioabsorbable constructs or the use of anchors. Each method possesses its own advantages and limitations. Here, we present a case involving a 13-year-old boy with a large purely chondral fracture of the lateral femoral condyle after patella dislocation, initially overlooked. We introduce a cost-effective suture-bridge technique for the fixation of this fracture, which eliminates the need for a second operation and has yielded favorable outcomes. It is important to know that fractures of this type can be easily overlooked, necessitating a high index of suspicion and the utilization of advanced imaging techniques to prevent potential long-term catastrophic outcomes for the knee joint.

OBJECTIVE: The risk of osteochondral fracture (OCF) after patellar dislocation has been shown to be related to patellofemoral anatomy, but its relationship to patellar morphology remains unknown. The aim of this study was to investigate the associations between patellar morphology and the risk of OCF after patellar dislocation.
METHODS: A total of 140 patients with patellar dislocation between January 2018 and June 2023 were enrolled in this study and divided into two groups. Sixty-five patellar dislocation patients with OCF were included in the OCF group, while 75 patellar dislocation patients without OCF were included in the non-OCF group. Computed tomography was used to compare measurements of patellar morphology including Wiberg classification, patellar width and thickness, Wiberg angle, Wiberg index, facet ratio, lateral patellar facet angle, and patellar tilt angle. A logistic regression model was performed to evaluate the correlations between patellar morphology and the risk of OCF after patellar dislocation. Receiver operating characteristic curves were used to calculate the area under the curve (AUC) and determine the diagnostic values of patellar morphology for OCF after patellar dislocation. Subgroup analyses for gender and age were conducted to compare the differences in patellar morphology of PD patients.
RESULTS: Wiberg angle was significantly lower in the OCF group (p = 0.017), while Wiberg index (p = 0.002) and facet ratio (p = 0.023) were significantly higher in the OCF group. According to the results of logistic regression analysis, Wiberg angle (odds ratio [OR] = 0.96, p = 0.022) and Wiberg index (OR = 1.105, p = 0.032) were the final relevant factors for the occurrence of OCF after patellar dislocation. The AUC was 0.622 (95% confidence interval [CI]: 0.529-0.714) for Wiberg angle, 0.65 (95% CI: 0.558-0.742) for Wiberg index, and 0.702 (95% CI: 0.615-0.788) for the combination of Wiberg angle plus Wiberg index.
CONCLUSIONS: Wiberg angle and Wiberg index were independent risk factors for the occurrence of osteochondral fracture after patellar dislocation. Moreover, Wiberg angle, Wiberg index, and the combination of Wiberg angle plus Wiberg index had good predictive diagnostic value for the occurrence of OCF after patellar dislocation.

Penetrating injuries to the musculoskeletal system pose common challenges for orthopedic surgeons in emergency departments (EDs). The complexity escalates when a joint is affected, increasing the risk of severe complications such as infection and post-traumatic arthritis. Given the potential importance of these injuries, early diagnosis and a meticulous treatment plan are crucial. In this paper, we present a unique case of penetrating trauma, resulting in an intra-articular defect on the lateral femoral condyle of an adolescent girl. This case underscores the importance of tailored interventions in managing complex musculoskeletal injuries.

OBJECTIVE: This retrospective observational cohort analysis aims to address diagnostic and therapeutic challenges in managing osteochondral fractures (OCFs) resulting from acute patella dislocation and ankle sprains in children.
METHODS: The study includes 15 children treated for OCFs between January 2020 and July 2022. Data were obtained from medical records and analyzed using logistic regression.
RESULTS: The diagnostic and treatment algorithm involves detailed history, clinical examination, and imaging, with MRI guiding therapeutic decisions. Arthroscopic or mini open fixation led to successful rehabilitation, with 93% achieving full mobility at 9 months. Age was identified as a slight risk factor for free fragments in MRI, and arthroscopic management correlated with faster recovery at 3 months.
CONCLUSIONS: This study underscores the importance of immediate diagnosis and minimally invasive intervention for OCFs in children. Timely treatment, guided by a diagnostic algorithm, facilitates joint restoration and prevents degenerative consequences, ensuring a return to regular activities within a year postoperatively.
METHODS: IV.

The incidence of articular injury, particularly osteochondral fractures (OCFs), has seen a cinnotable increase in recent years. Regardless of their location, fragments can be overlooked by plain radiographs, which might lead to osteoarthritis in the long run. Diagnostic imaging has a pivotal role in the assessment and classification of the fracture severity, as well as the presence of any associated dislocations. These fractures require surgical intervention for the restoration of joint function and the reduction of long-term complications. This paper aims to present the surgical correction and post-operative treatment of osteochondral fractures with absorbable implants in four children. The following affected areas are discussed: lateral condyle of the femur, patella and radial head. Utilising absorbable implants for the management of OCFs provides numerous advantages, including the elimination of the need for re-anaesthesia and reoperation, reduction of complications and facilitation of early rehabilitation. This approach also minimises the period of hospitalisation and proves effective in pediatric OCF treatment.

UNASSIGNED: Patella fractures in the pediatric age group often have a dilemma in their ease of diagnosis and treatment required. Indications for conservative management or surgical intervention in the pediatric population during growth phase are not clearly defined. The current systematic review aims to provide a consensus on the morphological types, treatment options, indications, the outcomes expected and complications and their management.
UNASSIGNED: The review was conducted as per the PRISMA guidelines. Inclusion criteria were (a).Articles published in English, (b) Age <18 years, (c) Patellar fractures including osteochondral fractures. Exclusion criteria includes articles with incomplete data, case reports, biomechanical studies, case series with sample size <2, biomechanical studies, reviews, letter to the editor, or editorials and Non-English language.
UNASSIGNED: The review search yielded a total of 18 articles. A total of 288 patients with patellar fractures were included in the review. The average age ranged from 9.6 years to 16 years. The follow-up period ranged from 3 months to 20 years. In total, 49 individuals underwent immobilization with cast or brace application, 4 with spica cast application and 48 with cylindrical cast in extension. Overall, 83 patients in 13 studies underwent surgical fixation most of which underwent wiring.
UNASSIGNED: Pediatric patella fracture/dislocations or Osteochondral fractures (OCF) although being a rare event, may be associated with a child with knee injury and swelling. Conservative management in terms of casting and immobilization may be an alternative but surgical intervention should be the primary mode of treatment in such cases.

The lateral talar dome osteochondral fracture has been described as shallow or wafer-shaped and is more likely to have an associated flake fracture than medial injuries. Displacement into the extracurricular space, however, is a rare occurrence. We present a case of ankle trauma with persistent pain and edema. A CT scan revealed a displaced osteochondral fracture of the lateral dome of the talus and an avulsion fracture of the tip of the medial malleolus. After appropriate dissection and exposure, the fragment was found below the skin, outside the ankle joint capsule. The fragment was fixed to the neck of the talus, and the deltoid ligament and anterior inferior tibiofibular ligament were repaired. After a one-year follow-up, full recovery was achieved without pain, stiffness, or osteonecrosis of the displaced fragment. Although the extra-articular displacement of lateral talar dome osteochondral fractures is rare, it should be considered when assessing ankle trauma.

UNASSIGNED: Medial patellofemoral ligament (MPFL) prevents lateral dislocation of the patella and acts as a major stabilizer. The tear could be associated with osteochondral avulsion fractures; however, intra-articular split fractures are not seen. Here, we present one unusual case of such a presentation.
UNASSIGNED: A 16-year-old male presented with a history of recurrent patellar dislocation and inability to bear weight following the last episode. The patient was diagnosed with an MPFL tear with an unusual intra-articular femoral condyle split fracture. The case had significant improvement in functional scores post-surgery.
UNASSIGNED: In physically active populations, twisting of the knee could result in an MPFL tear, leading to recurrent patellar dislocation. The treatment remains ligament reconstruction, open, or arthroscopic. Associated intra-articular fractures are very rare with such injuries and need to be addressed due to the high rate of non-union.

Preservation of articular cartilage in the setting of acute or chronic injury in the adolescent and young adult knee is paramount for long-term joint health. Achieving osseous union, minimizing implant-related injury, and eliminating the need for reoperation for traumatic chondral and osteochondral lesions (OCLs) and osteochondritis dissecans (OCD) remain a challenge for the orthopaedic surgeon.
To evaluate radiographic healing, patient-reported outcomes, and short-term complications after suture-bridge fixation of chondral fragments, osteochondral fractures, and OCD lesions in the knee.
Case series; Level of evidence, 4.
The study included consecutive patients (38 patients, 40 knees) treated within a single academic sports medicine institution who underwent suture-bridge fixation of an OCL or an OCD lesion of the knee from initiation of the technique in October 2019 through March 2021. The suture-bridge technique entailed bioabsorbable knotless anchors placed on the outside margins of the lesion with multiple strands of hand-tensioned absorbable (No. 0 or No. 1 Vicryl) or nonabsorbable (1.3-mm braided polyester tape) bridging suture. Healing was assessed by radiography and magnetic resonance imaging (MRI), with MRI scans obtained on all OCD lesions and any chondral-only lesions. MRI scans were available for 33 of 40 (82.5%) knees within 1 year of surgery and were evaluated for lesion healing. Complications and rates and timing of return to sport were evaluated. Patient-reported outcomes in the OCD cohort were evaluated with the Knee injury and Osteoarthritis Outcome Score (KOOS) to determine early pain and functional improvement.
In total, 33 (82.5%) lesions demonstrated full union, and no lesions failed treatment. MRI assessment of healing (mean, 5.8 months; range, 3-12 months) demonstrated 9 (64.3%) OCD lesions with full union, 5 (35.7%) OCD lesions with stable union, and no OCD lesions with nonunion. Of the OCLs, 17 (89.5%) had full union, 2 (10.5%) had stable union, and none had nonunion. The 7 bony OCLs without an MRI scan demonstrated complete radiographic union. In 30 (75.0%) lesions, patients returned to sports at a mean of 6.5 months (range, 3.8-10.2 months). KOOS Activities of Daily Living, Pain, Quality of Life, and Symptoms scores demonstrated significant improvement from baseline at 6 months and at 1 year. There were 2 (5%) complications, consisting of reoperation for marginal chondroplasty on an otherwise stable lesion, and re-operation for intial un-treated patellar instability, with no reoperations for failure or revision of the suture-bridge construct.
In this series of OCLs and OCD lesions of the knee, suture-bridge fixation demonstrated excellent rates of MRI and radiographic union and good early outcomes with minimal short-term complications. This technique may be used for lesion salvage as an alternative to metallic and nonmetallic screw/tack constructs in the treatment of these challenging lesions. Longer term follow-up and investigation are warranted.

Traumatic osteochondral fractures of metatarsal heads are rare injuries and are scarcely reported in the literature. Their classification and modalities of treatment remain unclear. Herein, we report two cases of traumatic fractures of the articular surfaces of the metatarsal heads in two young patients in which two different modalities of surgical treatment were used to achieve anatomic reduction and congruity of the metatarsophalangeal joints. The postoperative period was uneventful, and good functional and radiological outcomes were achieved in both patients. In this report, we review the literature for similar cases and discuss the available treatment options and their associated complications.
