Nail-patella syndrome is a rare disorder characterized classically by the tetrad of nail hypoplasia or aplasia, aplastic or hypoplastic patellae, elbow dysplasia, and the presence of iliac horns. Iliac horns are considered pathognomonic, and the presence of hypoplastic or aplastic patellae in conjunction with nail abnormalities is a cardinal feature of diagnosis.

REASONS FOR PERFORMING STUDY Lateral heel wedges are used to treat horses and ponies with patella fixation or bone spavin. However, these therapies are purely empirically based and lack scientific evidence. OBJECTIVES Lateral heel wedges would change joint motion in the sagittal, but mainly in the transversal planes, in healthy horses. This effect would be increased by restricted feeding and ...

OBJECTIVE To determine whether tissue angiotensin converting enzyme (ACE) is increased in synovia from patients with rheumatoid arthritis, osteoarthritis or chondromalacia patellae. METHODS Sections of synovia from patients with rheumatoid arthritis (n = 7), osteoarthritis (n = 7) or chondromalacia patellae (n = 6) were tested for immunoreactivity for ACE, and for binding of the ACE inhibitor...

OBJECTIVE To evaluate the clinical and radiographic results associated with the use of a percutaneous suprapatellar (SP) portal and accompanying instrumentation for tibial intramedullary nail (IMN) insertion using a semiextended approach. DESIGN Prospective, nonrandomized, nonconsecutive study. SETTING Level 1 trauma center. PATIENTS AND METHODS From June 2007 to January 2011, 56 fracture...

Management of patellofemoral joint pathology is challenging as a result of the unique and complex organization of static forces and dynamic factors contributing to its functional capacity. Anterior knee pain is a common musculoskeletal complaint seen daily in the practices of primary care physicians, rheumatologists, and orthopedic surgeons. The key to successful treatment lies not only in the ...

Complications and results of medial patellofemoral ligament (MPFL) reconstruction, performed between 2000 and 2003, were studied retrospectively in 24 randomised patients (24 knees). All procedures were performed for recurrent dislocation or subluxation of the patella, using an autogenous semitendinosus tendon. Two different methods of anchoring of the transplant were compared. After a 2-year f...
