Background: Rupture of anterior cruciate ligament (ACL) would cause instability and disability and if left untreated. Reconstruction is performed by different techniques including patellar bone graft, as the strongest device. Application of brace after ACL reconstructions has revealed doubtful results. Methods: One hundred ACL ruptured patients randomized into two groups were reconstructed with...

BACKGROUND AND PURPOSE Several mechanisms are responsible for patellar dislocation. We investigated how the primary pathomechanism relates to patient characteristics and the outcome. METHODS 126 patients (81 females) with primary patellar dislocation reported the knee position before the episode, the movement during it, and whether the patella was locked in dislocation. The median age was 20 ...

Many radiographic techniques have been described for measuring patellar height. They can be divided into two groups: those that relate the position of the patella to the femur (direct) and those that relate it to the tibia (indirect). This article looks at the methods that have been described, the logic behind their conception and the critical analyses that have been performed to test them.

PURPOSE The aim of this study was to investigate the pathoanatomic features of patellar instability by arthroscopically comparing patellofemoral congruence with rotation of the knee joint and/or electrical stimulation of the quadriceps (ESQ) between knees with and without patellar instability. METHODS We retrospectively examined 83 knee joints in 83 patients. The joints were classified into 2...

Introduction: Anterior Knee Pain (AKP) is one of the most common causes persistent problems after knee replacement. Total Arthroplasty (TKA) a surgical procedure in which an artificial joint or prosthesis replaces damaged knee. A significant proportion patients experience AKP surgery. The pain described as retro patellar peripatellar pain. Patients have trouble standing from sitting position, w...

BACKGROUND Abnormal patellar height is associated with anterior knee pain and several conditions that affect the patellofemoral joint. The aim of this study was to 1) report the incidence of patella alta and patella baja and 2) investigate whether the normal limits of the Insall-Salvati ratio is applicable in adult Middle-Easterners. METHODS A radiographic review of the lateral radiographs of...

The aim of this study was to assess the effect of patellar taping of the proprioceptive status of patients with patellofemoral pain syndrome (PFPS). A total of 32 subjects (18 males, 14 females of age 31.9 +/- 11.2, body mass index 25.8 +/- 5.3) with PFPS were tested for Joint Position Sense (JPS) using a Biodex dynamometer. Outcomes of interest were the absolute error (AE), the variable error ...

The source of osteoarthritic (OA) knee pain is perplexing. Bone marrow Lesions (BMLs) and the Infrapatellar Fat Pad (IPFP) are hypothesized to cause symptoms in this patient population. With escalating costs for OA treatment, physiotherapy could be an inexpensive option for managing OA knee pain. The aim of this study was to examine the Magnetic Resonance Imaging (MRI) of OA knee pain patients,...
