BACKGROUND Patella dislocation and re-dislocation are common diseases. Although patella dislocation is frequent, it always poses a challenge concerning diagnostics and therapy. Mixed forms of pathological disorder in the patellofemoral joint make the analysis of the malalignment and the choice of the correct treatment more difficult. MATERIAL AND METHODS By reviewing the available literature ...

Bilateral anterior shoulder dislocations are rarely seen and usually occur due to the same mechanism arising from traumatic injuries. In here, we discussed three cases of traumatic bilateral anterior shoulder dislocation , one had an additional patella fracture, and the other one had bilateral tuberculum majus fracture. All of the patients were female and our first case that presented here was ...

Osteochondral fractures of the patella are relatively common pediatric knee injuries, often missed during initial evaluation, and almost always associated with acute dislocations. We report case an adolescent patient a very large osteochondral fracture involving whole medial patellar facet without concomitant dislocation patella. A 16-year-old presented to emergency pain swelling in left after ...

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...

Patellofemoral arthroplasty is a treatment option for the relatively young patient with isolated patellofemoral osteoarthritis where conservative treatment has failed. However, despite of reasonable long term results, complications could be challenging. Loosening of the polyethylene patella component is a serious complication and has been reported in 2%. Dislocation of the polyethylene patella ...

The patellofemoral joint remains the enigma of orthopedics and sports medicine. Patellar dislocation is a common problem in the younger and athletic population and it is more disabling than cruciate ligament injuries. The pathology is often multifactorial and complex with no one factor being the sole defining etiology. The current management of patella dislocation has been linked with poor pati...

BACKGROUND Superior dislocation of the patella is an uncommon condition that mainly occurs in knees with a high patella and medial femorotibial degenerative arthritis. There are no previous reports of this condition occurring in association with tibial valgus osteotomy. CASE REPORT We report the case of a patient in whom vertical dislocation recurred twice at 4 months after tibial valgus oste...

BACKGROUND The present study aimed to describe a new safe and economical technique for medial patellofemoral ligament (MPFL) reconstruction with satisfactory clinical outcomes, and present the results of a four-year follow-up. MATERIAL AND METHODS Thirty-two patients with recurrent patella dislocation, who underwent MPFL reconstruction with two semi-patellar tunnels and hardware-free patellar f...
