“…During dislocation, the patella lies on the trochlear anterolateral margin, producing the typical pattern of injury involving the medial of the patella and the non-weight-bearing portion of the anterolateral femoral condyle [ 5 ]. Acute knee pain, with or without trauma and knee effusion, should raise suspicions about patellar dislocation associated with the osteochondral defect [ 4 , 5 ]. In patients with suspected lateral patellar dislocation, careful palpation of the lateral femoral condyle, especially in flexion, is recommended [ 2 , 3 ].…”

Osteochondral fracture (OCF) in the weight-bearing surface of the lateral femoral condyle, associated with patellar dislocation, is an uncommon lesion. We report three cases of acute lateral patellar dislocation with large OCF in the weight-bearing portion of the lateral femoral condyle. In patients with lateral patella dislocation or lateral femoral condyle OCF, careful physical examination, radiography and MRI are recommended to rule out any associated injury.

“…The patella usually dislocates laterally. Fractures associated with lateral patellar dislocation are avulsion of its medial border, and osteochondral fractures of the patella and lateral femoral condyle [3] . Intra-articular dislocation occurs less frequently with rotation of the patella about either its vertical or horizontal axis [4] , [5] , [6] , [7] , [8] .…”

The patella usually dislocates laterally. Less commonly, intra-articular dislocation occurs about either the vertical or horizontal axis. Patellar fractures are generally transverse with varying degrees of comminution, and less frequently vertical in the sagittal plane. We present a 9-year follow-up of a previously undescribed coronal patellar fracture associated with vertical axis dislocation of the patella. The mechanism of this severe injury is described.

“…Although fast and accurate diagnosis increases the possibility of restoring the articular surface by fixing the fractured fragment, no studies have so far reported the long-time clinical results including a MRI scan of the knee. Available articles are primarily based on case reports and low-number case series [2,[5][6][7][8][9][10][11]. Only a few articles are based on large case series with clinical and MRI follow-up [3,12].…”

Aim. The aim of the study was to analyze the clinical results and MRI scans after transpatellar osteochondral fracture fixation following patellar dislocation. Methods. Our study group comprised 17 patients with patellar dislocation followed by osteochondral fracture of the articular surface of the patella. All patients underwent surgery where the fractured osteochondral fragments of the patella were attached using the transpatellar suture technique. The mean age at the time of surgery was 14.1 years, and the mean follow-up period was 7.5 years. Results. The results of the patellar compression test and the apprehension test were negative in all patients. The mean Lysholm and Kujala scores were 89.2 and 89.6, respectively. The MRI scan revealed healing of the fixed fragment and restoration of the articular surface in all patients. In 16 cases, subchondral bone of the fixed fragment area was described as irregular: its articular cartilage was narrowed and not homogenous. Progressive degenerative changes were observed in the patellofemoral joint at follow-up in three patients. Conclusions. By fixing osteochondral fragments, the patellar articular surface can be restored. The MRI scans show that the cartilage in the reconstructed surface is narrowed after a mean 7.5-year follow-up.
