The low contact stress patellofemoral replacement consists of a trochlear component and a modular patellar component which has a metal-backed mobile polyethylene bearing. We present the early results of the use of this prosthesis for established isolated patellofemoral arthritis in 51 consecutive patellofemoral replacements in 35 patients. The mean follow-up was 25 months (5 to 60). The estimat...

Chronic patellofemoral instability can be a disabling condition. Management of patients with this condition has improved owing to our increased knowledge of the functional anatomy of the patellofemoral joint. Accurate assessment of the underlying pathology in the unstable joint enables the formulation of appropriate treatment. The surgical technique employed in patients for whom non-operative m...

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...

background: patellar mal tracking is responsible for pain and disability in patellofemoral pain syndrome (pfps). patellar kinesio taping may have different effects on short and long term usage. the aim of this study is to compare the effect of short term and long term patellar kinesio taping in patellar position on women with patellofemoral pain syndrome using magnetic resonance imaging (mri). ...

ଝ ¿Es la resonancia magnética realmente necesaria para la evaluación del mal alineamiento patelar? La experiencia peruana Dear Sir, In relation to the article entitled ''Usefulness of magnetic resonance imaging for evaluating patellar malalignment'' (Utilidad de la resonancia magnética en la evaluación del mal alineamiento patelar), published by Figueroa et al. in Revista Española de Cirugía Or...

Pain in front of the knee is common in athletes and is often called patellofemoral arthralgia, but it is difficult to prove that the pain arises in that joint. Thermograms of 30 athletes clinically considered to have patellofemoral arthralgia were compared with those of a similar number of unaffected athletes matched for age and sex. A comparison was also made with thermograms of two older grou...

The purpose of this Technical Note is to introduce a surgical technique using a fluid pressure pump, mid-lateral portal, and radiofrequency ablation for visualization, assessment, and subsequent, accurate/adequate removal of patellofemoral articular lesions for the treatment of patellofemoral compartment pathology. With the patient in the supine position, and an inflated thigh tourniquet, stand...

Carpal malalignments in malunion of distal radius fracture are considered as an adaptive response of the carpus to loss of normal architecture of the distal radius. This condition leads to mechanical overload, ligament attenuation and progressive dynamic instability around the wrist joint. Radial corrective osteotomy is suggested as a treatment option of carpal malalignment after distal radius ...

BACKGROUND Foot orthotics are commonly utilized in the treatment of patellofemoral pain (PFP) and have shown clinical benefit; however, their mechanism of action remains unclear. Patellofemoral joint stress (PFJS) is thought to be one of the main etiological factors associated with PFP. HYPOTHESIS/PURPOSE The primary purpose of this study was to investigate the effects of a prefabricated foot...

recurrent dislocation of patella may occur in patients with ligament laxity. method of treatment in this condition is controversial but patellofemoral ligament reconstruction is the most accepted method. we present a patient with rubinstein-taybi syndrome and recurrent patellar dislocation who managed successfully by patellofemoral ligament reconstruction.
