In this review the evidence for the management of patients with patellofemoral disorders is presented confined to anterior knee pain and patellar dislocation (excluding patellofemoral arthritis). Patients present along a spectrum of these two problems and are best managed with both problems considered. The key to managing these patients is by improving muscle function, the patient losing weight...

It has been suggested that recurrent dislocation, subluxation, and functional instability due to patellofemoral pain are experienced by 30% to 60% of patients with post-traumatic patella instability who are managed with non-surgical methods [1-3]. Recently, the medial patellofemoral ligament (MPFL) has been recognized as the most important ligamentous stabilizer for preventing lateral dislocati...

We estimated the patellofemoral joint forces generated during pedaling on a bicycle ergometer. Our calculations were based on measurements from a force transducer mounted on the pedal, 16-mm cine-film sequences, and biomechanical models of the cycling motion and of the patellofemoral joint. Six healthy male subjects cycled at different work loads, pedaling rates, saddle heights, and pedal foot ...

Prosthetic patellofemoral inlay resurfacing is a novel treatment concept for degenerative and focal arthrosis of the patellofemoral joint. The theoretic basis of this type of arthroplasty entails recreating ambient anatomy based upon intraoperative topographic mapping. The implant is intrinsically stable by virtue of the inset position relative to the surrounding joint surface. Articular resurf...

Introduction Total knee replacement (TKR) is the standard treatment for end-stage osteoarthritis when conservative measures have failed. Previous attempts to study coronal plane patellofemoral kinematics have suffered from the patella being obscured by the components and/or metal artefact (1,2). The aims of this study were: 1) To develop an accurate and reliable technique to measure patellofemo...

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...

OBJECTIVE To use forward dynamic simulations of forward and backward pedaling in order to determine whether backward pedaling offers theoretical advantages over forward pedaling to rehabilitate common knee disorders.DESIGN. A comparison of knee joint loads was performed during forward and backward pedaling.BACKGROUND. Pedaling has been shown to be an effective rehabilitation exercise for a vari...

Patellofemoral pain is seen frequently in young and physically active people. The incidence in primary care for the young adult age is about 10 to 12 new cases per 1000 patients per year, while in sports medicine practice, its prevalence may well be around 25%1. The palette of complaints is varied, from mild short-term pain to long-term and load-dependent pain, leading to functional restriction...

BACKGROUND Patellofemoral Pain Syndrome is one of the most common knee disorders among physically active young women. Despite its high incidence, the multifactorial etiology of this disorder is not fully understood. OBJECTIVES To investigate the influence of Patellofemoral Pain Syndrome on plantar pressure distribution during the foot rollover process (i.e., the initial heel contact, midstanc...

Introduction: Osteosynthesis of the femur using an interlocking nail is the gold standard for treating diaphyseal fractures of the femur. There are two established entry points for the antegrade interlocking nails which is the piriformis fossa or the greater trochanter. It has been reported that varus malalignment was frequently seen in proximal femur fracture which were treated with interlocki...
