BACKGROUND As longevity of cementless femoral components enters the third decade, concerns arise with long-term effects of fixation mode on femoral bone morphology. We examined the long-term consequences on femoral remodeling following total hip arthroplasty with a porous plasma-sprayed tapered titanium stem. METHODS Clinical data and radiographs were(More)

Dear Colleague: Precise measurements and clear identifi cation of bony landmarks are key to successful orthopedic surgery. The use of computer-assisted navigation, especially in minimally invasive surgery, maintains clear visibility during procedures, allowing the surgeon to obtain accurate measurements necessary for positioning implants in total hip(More)
AIMS An evidence-based radiographic Decision Aid for meniscal-bearing unicompartmental knee arthroplasty (UKA) has been developed and this study investigates its performance at an independent centre. PATIENTS AND METHODS Pre-operative radiographs, including stress views, from a consecutive cohort of 550 knees undergoing arthroplasty (UKA or total knee(More)
The Oxford Partial Knee (Zimmer Biomet, Bridgend, United Kingdom) has been used for the last four decades. Very few products make it to this milestone, not least in the world of medicine with the constant drive for innovation and improvement. The original design concept of John Goodfellow and John O'Connor, a fully congruent mobile meniscal bearing(More)
AIMS Since redesign of the Oxford phase III mobile-bearing unicompartmental knee arthroplasty (UKA) femoral component to a twin-peg design, there has not been a direct comparison to total knee arthroplasty (TKA). Thus, we explored differences between the two cohorts. PATIENTS AND METHODS A total of 168 patients (201 knees) underwent medial UKA with the(More)
