BACKGROUND Apart from transepicondylar axis, the native femoral sulcus was also reported to be used as a guide for the femoral component position in total knee arthroplasty (TKA). However, it was not shown in patients with severe knee osteoarthritis. This study was conducted to compare the position of trochlear groove in patients with and without osteoarthritis, and to assess whether trochlear ...

Patellofemoral pain (PFP) is a frequent cause of anterior knee pain in athletes, which affects patients with and without structural patellofemoral joint (PFJ) damage. Most younger patients do not have any structural changes to the PFJ, such as an increased Q angle and a cartilage damage. This clinical entity is known as patellofemoral pain syndrome (PFPS). Older patients usually present with si...

Purpose Patellofemoral instability is a common cause of anterior knee pain in adolescents and young adults. Most normal and pathological values for diagnosing patellofemoral instability are based on Western literature. We conducted this radiological study to determine normal values for different patellofemoral parameters in a Korean population and to evaluate their usefulness in diagnosis. Ma...

Decreases in patellofemoral pain have been demonstrated with bracing; however, the mechanisms of pain reduction remain unclear. Our purpose was to evaluate the hypothesis that patellofemoral bracing decreases peak pressure on the retropatellar surface through an increase in patellofemoral contact area. Nine cadaveric knees were tested during simulated free-speed walking with no brace, a knee sl...

OBJECTIVES To investigate whether there was a difference in hamstring length between patients with patellofemoral pain syndrome and healthy asymptomatic controls aged 18 to 35 years. DESIGN A cross-sectional observational study measuring hamstring length in patients and asymptomatic controls. SETTING Hospital physiotherapy department. PARTICIPANTS Two groups were tested; one group diagnos...

Patellofemoral pain syndrome is a common musculoskeletal condition and major cause for anterior knee pain. It has been associated with excessive compression between the patella lateral femoral condyle. one of those overuse disorder that can limit activity daily living along participation in sports. The prevalence more on female than male ratio 2:1 it affect athletic solely due to greater intern...

BACKGROUND Medialization and anteromedialization of the tibial tubercle are used to correct patellar subluxation in adults. PURPOSE To compare the effects of the 2 osteotomies on patellofemoral joint contact pressures and kinematics. STUDY DESIGN Controlled laboratory study. METHODS Tibial tubercle osteotomies were performed on 10 cadaveric human knees. The knees were tested between 0 deg...

BACKGROUND Musculoskeletal disorders specially knee osteoarthritis are the most common causes of morbidity in old patients. Disturbance of the mechanical axis of the lower extremity is one of the most important causes in progression of knee osteoarthritis. The purpose of the present study was to analyze the surgical results of distal femoral varus osteotomy in patients with genu valgum. METHO...
