The progression of gonarthrosis results in reduction of physical activity. One of the factors that increase the risk of osteoarthrosis may be joint overload related to the malalignment of the mechanical axis of the lower extremity. The medial compartment (MC) of the knee is particularly susceptible to overload due to the external knee adduction moment (EKAM). Varus knee malalignment contributes...

Introduction: Patients with patellofemoral instability with trochlear dysplasia may be treated with trochlear osteotomy. Case presentation: We present a patient with patellofemoral instability treated with trochlear osteotomy. The procedure resulted in nonunion with painful bony impingement and isolated patellofemoral osteoarthritis. Patellofemoral arthroplasty was performed. Conclusion: Patell...

Medial opening wedge high tibial osteotomy is a popular treatment option for medial compartment osteoarthritis of the knee. One of the proposed advantages is easier conversion to a total knee replacement compared to lateral closing wedge osteotomies, although there are few studies to support this. We reviewed the technical considerations in 36 knees in which conversion of a medial opening wedge...

The lateral subvastus approach combined with an osteotomy of the tibial tubercle is a recognised, but rarely used approach for total knee replacement (TKR). A total of 32 patients undergoing primary TKR was randomised into two groups, in one of which the lateral subvastus approach combined with a tibial tubercle osteotomy and in the other the medial parapatellar approach were used. The patients...

BACKGROUND Tarsal tunnel syndrome is a known complication of lateralizing calcaneal osteotomy. A Malerba Z-type osteotomy may preserve more tarsal tunnel volume (TTV) and decrease risk of neurovascular injury. We investigated 2 effects on the tarsal tunnel of the Malerba osteotomy compared to a standard lateralizing osteotomy using a cadaveric model: (1) the effect on TTV as measured by magneti...

background: postoperative periorbital edema and ecchymosis are common after rhinoplasty. we studied the effect of local injection of lidocaine/adrenaline immediately before osteotomy on prevention of post-operative periorbital edema and ecchymosis in rhinoplasty. m aterials and methods: thirty healthy candidates for rhinoplasty were enrolled in the self-controlled clinical trial study. lidocain...

BACKGROUND Anterior segmental osteotomy has become an established surgical technique to achieve functional occlusion and improve the facial profile in the treatment of maxillary protrusion. Postoperative nasal changes, however, are somewhat unpredictable. The here presented subapical anterior maxillary segmental osteotomy has been developed to avoid such unintended nasal changes. PATIENTS AND...

PURPOSE Past classification for the treatment of idiopathic genu vara depended simply on the measurement of distance between the knees, without attention to the rotational profile of the lower extremity. We retrospectively analyzed anatomical causes of idiopathic genu vara. PATIENTS AND METHODS Twenty eight patients with idiopathic genu vara were included in this study. All patients were surg...
