Rotational impairment of the knee (excessive adduction and internal rotation of the hip during weight-bearing activities) and hip muscles weakness have been proposed as one of the risk factors of PFPS. The effects of correction of these impairments, which are not related directly to patella-femoral joint, have not been studied up to now. The aim of this study was to compare the effects of “conventional physiotherapy alone” and “combined conventional physiotherapy with exercise therapy based on Sahrmann approach” in patients with PFPS.
In this randomized controlled clinical trial, 30 patients with PFPS (aged 20-50) were participated. The participants were divided into two groups: "traditional physiotherapy group" and “Sahrmann treatment group”. In both groups, interventions were applied for 6 weeks. Patients in traditional physiotherapy group only received TENS, hot packs, ultrasound, and knee exercise therapy. But in Sahrmann treatment group, in addition to traditional physiotherapy, posterior X taping, hip muscle strengthening and functional training was used. Before and immediately after the end of 6th week, quality of life variables (using questionnaires KOOS), pain (using the Visual Analogue Scale), and position sense of the knee were measured.
FINDINGS: All of the variables including pain, KOOS scale and position sense of the knee were significantly improved in both groups (p0.05).
Essentially, using of Sahrmann approach including “posterior X taping on thigh, strengthening of hip abductor, extensor and lateral rotators muscles”, compared to conventional physiotherapy, was not result in more effective improvement in patients with PFPS.

Bachground and The anterior cruciate ligament(ACL) has both mechanical and sensory function. Knee joint proprioception has been tested utilizing either reproduction of position or threshold to detection of passive motion in non-weight bearing positions. It has been suggested that more functional and dynamic/active tests of proprioception may clarify the effect of injury and reconstruction on the proprioceptive function of the ACL at the knee. The purpose of this study was assessment of knee joint position sense (JPS) following ACL reconstruction in functional position.12 patients who had undergone ACL reconstruction and 12 healthy control subjects participated in the study.JPS was evaluated by reproduction of the angles in weight-bearing position with limb movement into flexion and extension.The dominant-limb knee of healthy subjects and reconstructed and normal knee of the patients were selected for evaluation.The knee angles were measured by using a system comprised of digital photography, non-reflective markers and AutoCAD software. Absolute error was considered as a dependent variable.There were no significant differences between the operated and normal knee of the patients and between the patients and healthy control subjects. These results were observed in two tasks of limb movement into flexion and extension. The position had no significant effect on the absolute error in both groups. Conclusion and The result of this study suggest that subjects who have undergone ACL reconstruction do not have a deficit in knee JPS when tested under functional weight bearing conditions. Knee JPS is maintained by muscle-tendon receptors providing primary and accurate sensory information for normal proprioceptive function, along with remaining capsular and ligamentous mechanoreceptors which provide additional and/or complimentary proprioceptive information.
