Abstract EN
Complications of patellar dislocation include osteochondral injury of the lateral femoral condyle and patella.
Most cases of osteochondral injury occur in the anterior region, which is the non-weight-bearing portion of the lateral femoral condyle.
We describe two patients with osteochondral injury of the weight-bearing surface of the lateral femoral condyle associated with lateral dislocation of the patella.
The patients were 18- and 11-year-old females.
Osteochondral injury occurred on the weight-bearing surface distal to the lateral femoral condyle.
The presence of a free osteochondral fragment and osteochondral injury of the lateral femoral condyle was confirmed on MRI and reconstruction CT scan.
Treatment consisted of osteochondral fragment fixation or microfracture, as well as patellar stabilization.
Osteochondral injury was present in the weight-bearing portion of the lateral femoral condyle in both patients, suggesting that the injury was caused by friction between the patella and lateral femoral condyle when the patella was dislocated or reduced at about 90° flexion of the knee joint.
These findings indicate that patellar dislocation may occur and osteochondral injury may extend to the weight-bearing portion of the femur even in deep flexion, when the patella is stabilized on the bones of the femoral groove.
