introduction iatrogenic patellar fracture is reported as a complication of patella procedures, such as medial patellofemoral ligament reconstruction, reconstruction of the anterior cruciate ligament of the knee using bone-patellar tendon-bone technique, and resurfacing the patella in total knee arthroplasty. case presentation a 65-year-old lady with right patella fracture was treated with open ...

Knee osteoarthritis (OA) is a prevalent disease afflicting elderly people. As the knee joint is tri-compartmental, numerous radiographic patterns of disease are possible. The patellofemoral joint (PFJ) is one of the most commonly affected compartments. Although PFJ OA is frequently observed, this particular disease sub-group has gone largely unrecognised. Recent research suggests that not only ...

OBJECTIVE To quantify the role patellofemoral and tibiofemoral kinematics may play in development of anterior knee pain (AKP) in individuals with cerebral palsy (CP). DESIGN Case-control. SETTING Clinical research center. PARTICIPANTS Knees from individuals with diagnosed CP (n=20) and control knees (n=40) were evaluated. Controls were matched for sex and age based on the group average. M...

conclusions we feel this rare, currently unclassified variant of a tibial tubercle avulsion fracture should be recognised and consideration taken to adding it to existing classification systems. introduction a sleeve fracture classically describes an avulsion of cartilage or periosteum with or without osseous fragments and usually occurs at the inferior margin of the patella. tibial tubercle sl...

BACKGROUND Changing the kinematic behaviour of patellar movement could be one of the reasons for anterior knee pain after implantation of a total knee arthroplasty (TKA). The aim of the current study was to measure the potential influence on patellar kinematics of patellar resurfacing during TKA. METHODS Patellar movement before and after TKA with and without patellar resurfacing was measured...

Introduction. The feasibility of X-ray examination in the diagnosis gonarthrosis knee joint has been increasingly questioned recent years due to impossibility visualizing soft tissue elements; instead, magnetic resonance imaging as a priority method radiation diagnostics is considered more appropriate. goal this study investigate structural and functional state joints patients with monogonarthr...

The patella (kneecap) is the largest and best-known of the sesamoid bones, postulated to confer biomechanical advantages including increasing joint leverage and reinforcing the tendon against compression. It has evolved several times independently in amniotes, but despite apparently widespread occurrence in lizards, the patella remains poorly characterised in this group and is, as yet, complete...

BACKGROUND In this study, the results of the partial lateral facetectomy of the patella to better patellofemoral motion and congruence are compared with the results of the osteophyte removal of the patella and neurectomy only in total knee arthroplasty (TKA). METHODS Data from 55 patients undergoing TKA with osteophytes removal of the patella and neurectomy only, and those undergoing osteophy...

Three hundred and nineteen patients who had chondromalacia patellae and persistent patellofemoral pain after six months of conservative management underwent arthroscopy and arthroscopic surgery. The results in four aetiological groups were reviewed at one year and five years after operation. Morbidity was minimal. Lavage produced early remission in all groups. Shaving offered a particular advan...
