Background Total knee arthroplasty (TKA), aiming at neutral mechanical alignment (MA),
inevitably modifies the patient's native knee anatomy. Another option is kinematic alignment (KA…

Purpose Kinematic total knee arthroplasty (TKA) is an emerging technique, but concerns
remain around the effect of implanting the prosthesis in more anatomic orientations. Native …

Purpose The collum femoris preserving (CFP) uncemented prosthesis has a bone-preserving,
high subcapital neck resection and a short anatomical stem. The ideal arthroplasty option …

Few studies of total hip arthroplasty (THA) implants with a large-diameter femoral head and
metal-on-metal design have directly compared the progression of metal ion levels over time …

There is increasing interest in the use of patellofemoral joint replacements and the cohort
receiving them are the youngest of any of the groups of patients undergoing a knee arthroplasty…

Purpose The place of knee arthroscopy as a therapeutic option for osteoarthritis (OA) has
been the subject of some debate. The hypothesis for this study was that arthroscopic …

In 2018, the International Society for Hip Preservation Surgery (ISHA) initiated a series of
Delphi consensus studies to identify the global hip preservation community’s current opinion …

Aims Acetabular retroversion is a recognized cause of hip impingement and can be influenced
by pelvic tilt (PT), which changes in different functional positions. Positional changes in …

Introduction: Metal ion release from wear and corrosion at the femoral head-stem taper
junction can evoke local adverse reactions to metal debris (ARMD). In a specific large-diameter …

Introduction: Instability accounts for 1/3 of revision total hip arthroplasty (rTHA) performed in
the UK. Removal of well-fixed femoral stems in rTHA is challenging with a risk of blood loss …
