BACKGROUND Valgus high tibial osteotomy (HTO) may be associated with changes in the patellar height and posterior tibial slope. HYPOTHESIS Patellar height increases and posterior tibial slope decreases after closed-wedge HTO, whereas patellar height decreases and tibial slope increases after open-wedge osteotomy. STUDY DESIGN Cohort study; Level of(More)
Radiographs of 110 patients who had undergone 120 high tibial osteotomies (60 closed-wedge, 60 open-wedge) were assessed for posterior tibial slope before and after operation, and before removal of the hardware. In the closed-wedge group the mean slope was 5.7 degrees (SD 3.8) before and 2.4 degrees (SD 3.9) immediately after operation, and 2.4 degrees (SD(More)
BACKGROUND Osteochondral lesions of the ankle are a common injury after ankle sprains, especially in young and active patients. The Osteochondral Autograft Transfer System (OATS) is the only 1-step surgical technique designed to replace the entire osteochondral unit. PURPOSE This study was conducted to evaluate the long-term clinical and radiographic(More)
It is currently unknown in which ways activity of the ab- and adductor shoulder muscles affects shoulder biomechanics (scapular kinematics and glenohumeral translation), and whether these changes are relevant for alterations of the subacromial space width. The objective of this experimental in vivo study was thus to test the hypotheses that potential(More)
A steep tibial slope may contribute to anterior cruciate ligament (ACL)-injuries, a higher degree of instability in the case of ACL insufficiency, and recurrent instability after ACL reconstruction. A better understanding of the significance of the tibial slope could improve the development of ACL injury screening and prevention programmes, might serve as a(More)
BACKGROUND Autologous osteochondral transplantation is accepted as one of the major treatment options for cartilage defects of the talus. One disadvantage of this technique is the need to harvest a donor graft from a normal knee. The potentially detrimental effect of graft harvest on knee function remains unclear. METHODS Two hundred patients who had(More)
The purpose of this retrospective study was to investigate the rate of non-union after medial open-wedge high tibial osteotomy (HTO) with the Tomofix® plate. In addition, risk factors with a possible influence on the development of a non-union were analysed. Between 2006 and 2008, a total of 186 medial open-wedge HTOs were performed in 182 patients. Ten(More)
BACKGROUND Patients with genu varum of the knee and moderate to severe osteoarthritis often suffer from additional symptoms of the patello-femoral joint. These patients have a poor prognosis following high tibial osteotomy. It is unclear whether varus knees with only mild femoro-tibial osteoarthritis are also associated with alterations of patella(More)
While static MRI of the TMJ is the method of choice to evaluate the articular disk (AD), dynamic MRI so far has failed to display the AD. The capability of a modified True-FISP sequence to visualize the AD in dynamic near-real-time imaging (NRTI) was evaluated. Twelve healthy subjects and 17 patients were investigated. Besides static routine imaging,(More)
Ollier's disease is characterised by severe deformity of the extremities and retarded growth because of multiple enchondromas. For correction of deformity, the Ilizarov method has been used although it has many complications. A 17-year-old boy with Ollier's disease had a limb-length discrepancy of 17.4 cm, with a valgus deformity of the right knee and(More)
