Osteotomy

PURPOSE: To give an overview of the basic knowledge of the functional surgical anatomy of the proximal lower leg and the popliteal region relevant to medial high tibial osteotomy (HTO) as key anatomical structures in spatial relation to the popliteal region and the proximal tibiofibular joint are usually not directly visible and thus escape a direct inspection. METHODS: The surgical anatomy of the human proximal lower leg and its relevance for HTO are illustrated with a special emphasis on the individual steps of the operation involving creation of the osteotomy planes and plate fixation...

BACKGROUND: The aim of this prospective and randomized study was to evaluate the effectiveness of adding nanohydroxyapatite (NHA) to heterologous bone graft in open wedge high tibial osteotomy (OWHTO) by measuring the bone density of the tibial osteotomy gap. METHODS: Twenty-seven patients (26 knees) were operated by OWHTO and randomly divided into two groups: pure graft group, in which the osteotomy gap was filled with only heterologous bone graft; nanohydroxyapatite group, in which the osteotomy gap was filled with heterologous bone graft and NHA...

PURPOSE: To evaluate sporting activity following osteochondral autologous transfer (OAT) combined with valgus high tibial osteotomy (HTO) in young and active patients with focal osteochondral defects of the medial femoral condyle and concomitant varus malalignment. METHODS: Thirty patients with focal osteochondral defects of the medial femoral condyle and varus malalignment >2° were enrolled. All patients were active in sports on a regular base prior to surgery (lifetime), but were unable to perform sports at the time of surgery...

INTRODUCTION: This study reports a series of patients operated on by anterior cruciate ligament (ACL) reconstruction combined with valgus high tibial osteotomy (HTO) for chronic anterior knee instability associated with medial tibiofemoral osteoarthritis. It was hypothesized that the combined surgery would enable return to sport, stabilize the knee and relieve medial pain. PATIENTS AND METHODS: A retrospective study enrolled a continuous series of 29 patients (20 males, nine females; mean age, 43 years (range, 25-56 yrs), at a mean 14 years (range, 2-29 yrs) after the initial injury...
