We hypothesized that a number of clinical and radiologic parameters could influence the reducibility of varus deformity in total knee arthroplasty. The aim of this study was to identify the factors correlated with reducibility of varus deformity and predict more accurately the amount of medial soft tissue release required in varus deformity total knee arthroplasty. ⋯ The present study shows that preoperative varus deformity and proximal tibial vara (measured by preoperative mechanical axis angle and mechanical tibial angle, respectively) are correlated with reducibility of varus deformity (measured by preoperative valgus stress angle), and clinical parameters (age, range of motion, duration of pain and body mass index) and other radiologic parameters (osteophyte size, severity of osteoarthritis and angulation of distal femoral joint surface) were not significantly correlated with reducibility of varus deformity.

This study examined the clinical outcomes of indirect reduction maneuver and minimally invasive approach for treating displaced proximal humerus fractures in patients older than 60. ⋯ The indirect reduction maneuver and minimally invasive approach were safe and reliable options for the treatment of displaced proximal humerus fractures in the elderly patients. An inadequate reduction (i.e., less than 110° NSA) or lack of medial support (e.g., no cortical or screw support) were significant factors contributing to poor functional outcomes.
