OBJECTIVES Little biomechanical information is available about kinematically aligned (KA) total knee arthroplasty (TKA). The purpose of this study was to simulate the kinematics and kinetics after KA TKA and mechanically aligned (MA) TKA with four different limb alignments. MATERIALS AND METHODS Bone models were constructed from one volunteer (normal) and three patients with three different k...

Severe congenital web formation in the limbs and neck is uncommon, and often hereditary. Shun-Shin (1954), reporting a large Mauritian family with congenital antecubital webbing in three generations, made a comprehensive review of the literature on this subject in general, and the two siblings with extensive popliteal webbing described in this paper resemble the patients reported by Wolff (1889...

BACKGROUND To obtain the correct coronal alignment and balancing in flexion and extension, we established a selective medial release technique and investigated the effectiveness and safety of the technique during primary total knee arthroplasty (TKA). METHODS Four hundred sixty-six primary TKAs with varus deformity were prospectively evaluated between June 2013 and June 2015. A knee joint pos...

Reverse Segond fracture is an uncommon avulsion fracture of the tibial attachment of the deep portion of the medial collateral ligament of the knee. We report a reverse Segond fracture associated with anterior cruciate ligament tibial avulsion fracture and anteromedial tibial rim fracture. Unlike previous reports, the combination of reverse Segond fracture, anteromedial tibial rim fracture, and...

The surgical management of pilon fractures has evolved over the last several years with treatment shifting from acute definitive fixation to delayed fixation. One of the driving forces behind this change was the high incidence of soft tissue complications in those patients with high-energy pilon fractures (Orthopaedic Trauma Association 43B and 43C) managed with acute stabilization. Meticulous ...

OBJECTIVES To understand the factors that influence joint cartilage in health and disease as they are important for the prevention and management of osteoarthritis. METHODS We conducted a cross-sectional study to determine factors influencing knee cartilage volume in 45 males aged (mean+/-S.D.) 52.5+/-13.2 yr. RESULTS Total and medial tibial volumes were inversely associated with age, body ...
