Background: There have been debates on the necessity of fibular osteotomy (FO) in supramalleolar osteotomy (SMOT) for the treatment of varus ankle osteoarthritis. The purpose of the current study was to compare the clinical and radiological outcomes between SMOT with and without FO in the treatment of varus ankle osteoarthritis.
Methods: The SMOT group included 39 patients, and the SMOT with FO group included 24 patients. The basic information reached no significant difference between groups. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Ankle Osteoarthritis Scale (AOS), modified Takakura stage and range of motion (ROM) were used for the functional evaluation. The radiologic parameters were assessed at the last follow-up to compare the degree of talar reduction between the two groups.
Results: Both groups achieved significant improvements in AOFAS scores, modified Takakura stage, as well as AOS pain and functional scores (P < 0.001). The ROM of the ankle joint in the SMOT group was significantly decreased (P = 0.022). In both groups, all of the radiological parameters were significantly improved (P < 0.01). The tibiofibular clear space (TFCS) was significantly widened in the SMOT group (P < 0.001). No significant difference was found between the two groups according to the functional outcomes. However, the talar tilt angle (TT) and hindfoot alignment angle (HFA) in the SMOT with FO group were significantly smaller than those in the SMOT group (P < 0.05). The TFCS was significantly widened in the SMOT group (P = 0.001). The medial displacement of the talus (MDT) was better reduced in the SMOT with FO group (P = 0.006).
Conclusion: SMOT is a promising procedure for functional improvement and malalignment correction in varus ankle osteoarthritis but reduces ankle range of motion. If SMOT is combined with FO, talar tilt and medial displacement will be better reduced.

Introduction: High tibial osteotomy (HTO) is used to treat medial knee osteoarthritis (OA). A simple clinical test to select the patients most likely to benefit from the procedure was suggested by R. A.

Background: It is known that open wedge high tibial osteotomy (OWHTO) may lead to progression of patellofemoral degeneration due to descent of the patellar height. However, the difference in patellofemoral joint (PFJ) loads with normal daily activity between uniplane and biplane osteotomies is unclear. The purpose of this study was to reveal the differences in PFJ biomechanics between uniplane and biplane OWHTO using finite element analysis (FEA).

Knee pain in patients often involves varus deformity and unicompartmental osteoarthritis (OA). High tibial valgus osteotomy (HTO) is increasingly recognized as an effective treatment, as it realigns the knee's mechanical axis towards the healthier lateral compartment, delaying degenerative changes in the medial compartment and reducing the need for joint replacement. This case report discusses two patients with bilateral knee arthritis and varus deformity who underwent medial opening-wedge high tibial osteotomy (MOWHTO) using Dr.

Background: It is still unknown if the double-femoral tunnel technique (Arciero [ARC]) provides better stability as compared with the single-femoral tunnel technique (modified Larson [LAR]) in posterolateral corner reconstruction. The ideal angle of fixation of the popliteofibular strand in ARC is also unknown.
Hypotheses: The ARC provides greater external rotation (ER) stability than the LAR (hypothesis 1); there is no difference in varus rotation (VR) stability between LAR and ARC (hypothesis 2); and femoral fixation of the popliteofibular strand at 60° during the ARC leads to greater ER stability than fixation at 30° or 90° of knee flexion (hypothesis 3).

Subtrochanteric femoral fractures are one of the common fractures encountered in today's Orthopaedic practice. This area consists of mostly cortical bone with high stress generation thus heal slowly which leads implant failure. The inherent instability of this fracture and forces of the muscles with comminuted medial calcar is giving the fracture a tendency to varus collapse.
