Trochlear dysplasia is a developmental condition characterised by an abnormally flat or dome-shaped trochlea and is an important contributory factor to patellofemoral instability and recurrent dislocation. We studied prospectively a series of 54 consecutive patients (59 knees) with patellofemoral instability secondary to trochlear dysplasia, who were treated by a trochleoplasty by a single surg...

In recent years, the medial patellofemoral ligament (MPFL) has been considered as the primary restraint of the medial patellar stabilizers [1]. Clinical reports have revealed that MPFL injury occurs in almost all patients with traumatic patellar dislocation, and attention has been focused on the repair and reconstruction of the MPFL in recurrent patellar dislocation and patellar subluxation [2]...

Patellofemoral dysfunction, due to either a patellofemoral malalignment or patellar instability, is a complex and debilitating condition that significantly decreases the knee function. Conservative management may yield significant clinical outcomes; however, when morphologic anomalies are identified, the surgical approach should be employed. Hence, several surgical procedures have been describe...

Several options exist for the treatment of recurrent patellar dislocation. In our institution a specific treatment algorithm for patellofemoral maltracking, depending on skeletal maturity and the recognition of local risk factors has been in use for several years. The aim of our study was to evaluate the overall results of using this algorithm and to compare the outcome of the different subgrou...

Femoral trochlear dysplasia is an anatomic deformity that predisposes patients to patellar instability, including patellar subluxation and dislocation, and can lead to severe patellofemoral joint degeneration if left untreated. Femoral trochlear dysplasia leading to recurrent bilateral patellar dislocation has rarely been reported as having a familial association. Orthopedic surgeons who encoun...

OBJECTIVE To evaluate double-bundle reconstruction of the medial patellofemoral ligament (MPFL) using a graft from the semitendinosus tendon and fixation with metal anchors over the medium term. METHODS This was a prospective cross-sectional study. After approval from the research ethics committee, 31 patients with patellofemoral instability who underwent MPFL reconstruction by means of the a...
