Overdebridement is avoided to preserve the bone attached to the fragment. Inclusion criteria were: high-grade chondral lesions of PFJ (5 knees), or recurrent patella dislocations with trochlear dysplasia and chondral injury to the patella and/or trochlea (13 knees). Based on the clinical, radiological, and arthroscopic examination, arthrotomy was performed by medial or lateral parapatellar incision beginning from the superior base of patella and ending in the inferior apex of patella by taking the affected articular surface as reference. Wall Shital N. Parikh INTRODUCTION Pathogenesis An osteochondral injury can occur in up to 71% to 93% of patients during an acute patellar dislocation.1,2 The chondral and osteochondral injury can vary from minor cartilage scuffing or fissuring, to large full-thickness free fragments greater than 3 cm diameter or… Furthermore, on standard knee X-rays these injuries … An injury to this cartilage and the underlying bone is called an osteochondral fracture. Often the knee is partly bent, painful and swollen. The main site of osteochondral fracture was the medial facet, and the main site of cracks was the central dome. Acute patellar dislocation(APD) is a common injury in the pediatric patient population and may be associated with a spectrum of soft tissue and osteochondral injuries. Patients can develop patellofemoral pain for several reasons, including acute trauma and overuse injuries. Our study group comprised 17 patients with patellar dislocation followed by osteochondral fracture of the articular surface of the patella. Typically, this injury is a closed fracture. Osteochondral Fractures are also sometimes known as articular cartilage injuries. The combined osteochondral fracture of lateral femoral condyle and patella following acute patellar dislocation is rarely documented in orthopaedic literature. Methods . Less common are impression fractures of the retropatellar joint or the lateral trochlea. Patellar osteochondral fracture is an injury frequently associated with patellar instability, which may onset in the first episode. 5-10% of people > 40 years old have high grade chondral lesions; location. Patellar instability is a common cause for osteochondral injury of the patella. Pain results when the knee and the thigh bone (femur) rub together. Osteochondral injury is commonly associated with immediate effusion that represents hemarthrosis or lipohemarthrosis. These injuries were to the patella and to the lateral trochlear portions of the lateral femoral condyle. The underlying cause may be rooted in a chondral defect. Twelve knees (31%) had cartilage injury of the lateral femoral condyle. What are osteochondral injuries? This cartilage covers most of the talus, with the tibia (shin) and fibula (calf) bones above … The exact incidence and prevalence within … OCLs (osteochondral lesions of the talus) consist of damage or minor fractures to cartilage’s surface on the lower bone of the talus (ankle joint). Symptoms of an Osteochondral Fracture: Pain. The medial location of the lesions and the involvement of the system of medial knee stability is a fundamental finding. The location of the abnormality is dictated by the mechanism of injury. Osteochondral lesion of 1 cm 2 in the central–medial facet of patella. chronic ACL tear. When the patella is pushed back into place, the quadriceps will fire and this can cause a compressive force as the patella moves of over the lateral femoral condyle and cause a piece of the bone to fracture off. Chondromalacia patella (knee pain) is the softening and breakdown of the tissue (cartilage) on the underside of the kneecap (patella). ICD-10-CM Code for Osteochondral fracture of patella S82.01 ICD-10 code S82.01 for Osteochondral fracture of patella is a medical classification as listed by WHO under the range - Injury, poisoning and certain other consequences of external causes.
