The medial patellofemoral ligament (MPFL) has been recognized as an important soft tissue restraint in preventing lateral patellar translation. As many patients with acute or chronic patellar instability will have a deficient MPFL, reconstruction of this ligament is becoming more common. Appropriately, significant research has been undertaken regarding graft biomechanics and techniques, as intr...

BACKGROUND The intent of the present study was to determine the effectiveness of massage therapy in the rehabilitation of post-anterior cruciate ligament reconstruction patellofemoral pain syndrome. The primary complications following surgical repair of the anterior cruciate ligament-classified as patellofemoral pain syndrome-are hamstring flexion contracture and quadriceps weakness, leading to...

It is not currently understood which subset of patients with recurrent patellofemoral instability require concomitant bony realignment procedures in addition to a soft tissue stabilization. Additionally, the optimal timing surgical intervention well defined by current literature and can be dictated skeletal maturity patient. If patient’s complete pathology addressed at their primary procedure, ...

There are multiple etiologies for recurrent patellar instability. While patella alta, an elevated tibial tubercle trochlear groove distance, and prior lateral patellar dislocations with medial patellofemoral ligament (MPFL) insufficiency have been shown to be risk factors for recurrent patellar instability, trochlear dysplasia can result in a significant impediment to normal patellar tracking. ...

Joint squeaking has classically been described after total hip arthroplasty using a ceramic-on-ceramic bearing surface. This phenomenon has also been found to occur after total knee arthroplasty and can be associated with patient concern and dissatisfaction. However, it has not been described in the postsurgical native knee. We present 2 cases of knee squeaking after medial patellofemoral ligam...

OBJECTIVES To evaluate the compartmental distribution of knee osteoarthritis (OA) after anterior cruciate ligament reconstruction (ACLR), to determine if patellofemoral or tibiofemoral OA is more strongly associated with knee symptoms and function, and to evaluate the contribution of associated injuries and surgical delay to the development of OA. METHODS This cross-sectional study recruited ...

conclusions the clinical examination is an important and accurate diagnostic modality for evaluation of traumatic derangement of the knee joint. it is noninvasive, easy, available, and valuable diagnostic modality. the mri is an accurate diagnostic modality. it can be used whenever there is an uncertain indication for arthroscopy. however, costs have to be kept in mind, especially in patients w...

[Purpose] To compare the effects of open-chain exercise (OCE) and closed-chain exercise (CCE) for patients after medial patellofemoral ligament (MPFL) reconstruction. [Subjects and Methods] Forty patients after MPFL reconstruction were randomly divided into an OCE group and a CCE group. All the patients were evaluated at four different time points. [Results] The mean change of thigh circumferen...

BACKGROUND Recurrent patellar dislocation is common clinically, primarily in adolescents. However, the biomechanical properties of single- and double-bundle medial patellofemoral ligament (MPFL) reconstruction remain poorly understood. METHODS Six fresh frozen adult cadaveric knee specimens were obtained for this study. Each specimen was fixed at 0° to test the force needed when the patella w...
