Patellofemoral pain syndrome (PFPS) is one of the most common knee disorders, with pain located primarily in the lateral aspect of the patellofemoral joint. Force imbalance in the knee extensor muscles has been associated with changes in patellofemoral tracking and is suspected to cause PFPS [1]. Specifically, weakness of the vastus medialis (VM) relative to the vastus lateralis (VL) is the usu...

To evaluate the development of postoperative patellofemoral osteoarthritis, we performed a retrospective clinical and radiographic study of 100 patients who had undergone anterior cruciate ligament reconstruction with a bone-patellar tendon-bone autograft an average of 7 years before the follow-up. Radiographic evaluation showed no patellofemoral osteoarthritis in 53 patients (group I), mild os...

PURPOSE To determine the value of the 2D multiple-echo data image combination (MEDIC) sequence relative to the short-tau inversion recovery (STIR) sequence regarding the depiction of chondral lesions in the patellofemoral joint. MATERIALS AND METHODS During a period of 6 month patients with acute pain at the anterior aspect of the knee, joint effusion and suspected chondral lesion defect in t...

Isolated patellofemoral osteoarthritis is now recognised to be more common than previously thought. The features and management are reviewed, including the various surgical options in symptomatic patients. The evidence base for managing patellofemoral osteoarthritis is behind that for the tibiofemoral joint. All treatments are based on uncontrolled observational case series, typically retrospec...

Subtle instability problems of the glenohumeral joint and patellofemoral joint are difficult to assess and accurately diagnose with current methods of preoperative imaging and physical examination. A simple technique is described that provides objective information for diagnosing dynamic problems of the shoulder and patellofemoral joint. Limited-volume gas arthroscopy avoids many of the potenti...

Patellofemoral pain syndrome (PFPS) [2] PFPS is a diagnosis of exclusion and is defined as pain behind or around the patella. It is synonymous with the term retro-patellar pain and has in the past been referred to as chondromalacia patellae. It is caused by compressive forces in the patellofemoral joint (PFJ). PFPS is very common. Symptoms are usually provoked by climbing or descending stairs, ...

Patellofemoral problems often begin with instability in young patients and become progressively disabling. Effective treatment requires understanding a complex combination of knee alignment, soft tissue influences on patellar tracking and stability, joint forces and the condition of articular surfaces. Management of patellofemoral conditions usually begins with directed physical therapy, variou...

objectives: patellar maltracking is the main reason for pain and disability in patellofemoral pain syndrome (pfps). patellar taping can considerably reduce such pain and disability. this study compared the effectiveness of physiotherapy exercises and kinesio taping on the patellar position in women with pfps (mean age 32.2±1.12 years) by using magnetic resonance imaging (mri). methods: thirty w...
