Articular cartilage injuries of the knee and ankle are common, and a number of different methods have been developed in an attempt to improve their repair. Clinically, there are 2 distinct aims of cartilage repair: 1) restoration of joint function and 2) prevention or at least delay of the onset of osteoarthritis. These goals can potentially be achieved through replacement of damaged or lost ar...

Damage to the anterior talofibular ligament (ATFL) and cacaneofibular ligament (CFL) during an ankle sprain may be linked to the development of osteoarthritis. Although altered tibiotalar kinematics have been demonstrated, the effects of lateral ankle instability (LAI) on in vivo cartilage strains have not been described. We hypothesized that peak cartilage strains increase, and the location is...

BACKGROUND Tibiotalocalcaneal arthrodesis is most common and effective surgical treatment for severe hindfoot pathology, but the fusion rate is often lower than the ordinary tibiotalar arthrodesis because of the more serious joint disease associated with obvious deformity and osteoporosis. Recent literature describe tibiotalocalcaneal arthrodesis with reverse PHILOS plate with good clinical out...

Eight patients with disabling tibiotalar arthritis (one patient with a supramalleolar nonunion) were treated by arthrodesis. The procedure in all of these patients consisted of internal compression obtained by bone plates and the application of a bilateral tension device. A bilateral surgical approach was used. No bone grafting was required. This study compares two groups immobilized for ten an...

Background Previous in vivo studies on total ankle arthroplasty (TAA) kinematics were mainly performed using skin marker analysis, which has the drawback of skin movement artefacts [1]. A further limitation is the inaccessibility of the talus for attaching markers, thus the impossibility to distinguish tibiotalar from subtalar motion. So far it is not known how well skin marker analysis detects...

Methods Fifty consecutive JIA patients, followed at the study center, with clinically-detected ankle involvement were enrolled. If both the ankles were involved, only the most affected side was selected for US. All clinical and US examinations were performed at the same day by experienced physicians and ultrasonographers, respectively, blinded to each other evaluations. US findings were collect...

BACKGROUND AND PURPOSE The association of leg length discrepancy (LLD) with a number of clinical disorders has made its determination a significant part of the physical examination. We believe that submalleolar causes of LLD may be under-acknowledged. The most common clinical method used to measure LLD is by tape from the anterior superior iliac spine (ASIS) to medial malleolus which disregards...
