OBJECTIVE To investigate if the increased proteoglycans in patellar tendinopathy involves a qualitative change in the types of proteoglycans. DESIGN This is an observational study based on the biochemical analysis of proteoglycans. SETTING : University Teaching Hospital. PATIENTS Patellar tendon samples from 12 patients with patellar tendinopathy and 12 healthy controls were collected and...

The occurrence of combined injury of intrusion, avulsion and lateral luxation is rare and the mechanism responsible for this is intriguing. This case report describes such a combined injury and its management. The rationale behind the treatment modalities is discussed.

Patellar tendon ruptures are rare but potentially devastating injuries. Acute repair after patellar tendon rupture affords the best opportunity for tension-free restoration of the extensor mechanism. Biological augmentation of primary repair is believed to decrease strain across the repair site and reduce the risk of rerupture. We present a technique for primary patellar tendon repair with bidi...

BACKGROUND Anterior knee pain is often associated with patellar maltracking and instability. However, objective measurement of patellar stability under clinical and experimental conditions is difficult, and muscular activity influences the results. In the present study, a new experimental setting for in vitro measurement of patellar stability was developed and the mediolateral force-displacemen...

The aim of this study was to evaluate the associations between patellar cartilage defects and body mass index (BMI), infrapatellar fat pad (IPFP) volume and age. 100 patients who met the inclusion criteria and were aged 18 to 60, were evaluated retrospectively. For detecting and measuring patellar cartilage defects, axial sequences were used and sagittal sequences were used to evaluate IPFP vol...

Late presentation of congenital patellar dislocation with advanced osteoarthritis is rare. This article presents a case of 56-year-old woman with advanced osteoarthritis due to right neglected congenital patellar dislocation treated with total knee arthroplasty (TKA) with release of the lateral retinaculum and proximal extensor mechanism realignment. One year later, the patient had improvement ...

Disagreement remains regarding the optimal treatment for intrusive luxation injuries to permanent teeth. Three problems often present themselves following intrusive luxation: improper tooth position, pulpal necrosis, and internal or external root resorption. In the recent past, the accepted treatment was to allow the permanent teeth to reerupt spontaneously for 6-8 weeks. If this did not occur,...

CONTEXT The rising popularity and intensity of youth sports has increased the incidence of patellar dislocation. These sports-related injuries may be associated with significant morbidity in the pediatric population. Treatment requires understanding and attention to the unique challenges in the skeletally immature patient. EVIDENCE ACQUISITION PubMed searches spanning 1970-2013. STUDY DESIG...
