Influence of patellar position on the knee extensor mechanism in normal and crouched walking.
Patella alta is common in cerebral palsy, especially in patients with crouch gait. Correction of patella alta has been advocated in the treatment of crouch, however the appropriate degree of correction and the implications for knee extensor function remain unclear. Therefore, the goal of this study was to assess the impact of patellar position on quadriceps and patellar tendon forces during nor...
متن کاملReconstruction of Chronic Patellar Tendon Ruptures With Extensor Mechanism Allograft
Chronic patellar tendon ruptures are a difficult clinical problem. Treatment options include repair and augmentation with hamstring tendons and other grafts. We describe a technique of extensor mechanism reconstruction using an allograft consisting of quadriceps tendon, a patellar bone block, patellar tendon, and a tibial bone block. This technique is a salvage procedure indicated only in the m...
متن کاملDoes Knee Extensor Muscle Imbalance Cause Changes in Patellar Tracking?
Patellofemoral pain syndrome (PFPS) is one of the most common knee disorder seen by clinicians. The main region of pain is the lateral aspect of the patellofemoral joint. Force imbalance in the knee extensor muscles has been associated with changes in patellofemoral tracking [1] and is suspected to cause PFPS. Weakness of the vastus medialis (VM) relative to the vastus lateralis (VL) is the usu...
متن کاملDoes total knee arthroplasty affect the patellar tendon reflex?
Background There may be a perception in clinical practice that any deficit in the patellar tendon reflex arc could be attributed to a total knee arthroplasty (TKA). There is no evidence in the literature to support this conclusion. Methods Sixty-six knees were examined to determine whether TKA affects the patellar tendon reflex. Results There was no difference observed between the knees with a ...
متن کاملExtensor Mechanism Reconstruction for Chronic Patellar Fracture.
Patients with displaced patellar fractures typically present with disruption to the extensor mechanism requiring acute surgical intervention. Chronic patellar fractures with disruption of the extensor mechanism are uncommon, and few surgical options are available. The authors present a patient who sustained a fracture to the inferior pole of the patella in Africa 5 years prior that was managed ...
