BACKGROUND AND PURPOSE There has recently been interest in the advantages of minimally invasive surgery (MIS) over conventional surgery, and on local infiltration analgesia (LIA) during knee arthroplasty. In this randomized controlled trial, we investigated whether MIS would result in earlier home-readiness and reduced postoperative pain compared to conventional unicompartmental knee arthroplas...

INTRODUCTION Patient satisfaction after total knee replacement (TKR) depends on the amount of pain relief and the functional activities achieved. An important criterion of good functional outcome is the amount of flexion achieved and whether the patient can manage high flexion activities. In order to increase the amount of safe flexion, various implant designs have been developed. This study ai...

BACKGROUND Patient function is poorly characterized following revision total knee arthroplasty (TKA), although is generally accepted to be inferior to that following primary procedures. METHODS Fifty-three consecutive aseptic revisions to total stabilizer devices were prospectively evaluated, preoperatively and at 6, 26, 52, and 104 weeks postoperatively, using the Oxford Knee Score (OKS), ra...

background: subjects with knee osteoarthritis typically have higher knee adduction moment. current research efforts are mainly focused on therapeutic procedures that potentially may modify disease progression. this preliminary study was designed as a single blind (examiner) randomized control trial to investigate the impact of conventional physical therapy on pain, and knee joint load in subjec...

Patient reported outcome measures (PROMs) were introduced in 2009 to allow patient perspectives to potentially influence change and improvement. In collaboration with the national joint registry (NJR), PROMs data has been examined on a national basis to compare surgical factors in total knee replacement (TKR). Initial results demonstrated there were statistically significant differences in Oxfo...

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 articulating with spherical femoral and flat t...

Aims To determine the trajectories of patient reported pain and functional disability over five years following total hip arthroplasty (THA) or knee (TKA). Methods A prospective, longitudinal cohort sub-study within National Joint Registry (NJR) was undertaken. In all, 20,089 patients who underwent primary THA 22,489 TKA between 2009 2010 were sent Oxford Hip Score (OHS) Knee (OKS) questionnair...

OBJECTIVES Preservation of posterior condylar offset (PCO) has been shown to correlate with improved functional results after primary total knee arthroplasty (TKA). Whether this is also the case for revision TKA, remains unknown. The aim of this study was to assess the independent effect of PCO on early functional outcome after revision TKA. METHODS A total of 107 consecutive aseptic revision...
