OBJECTIVE To compare characteristics of patients and outcomes after elective surgery in independent sector treatment centres (ISTCs) and NHS providers. DESIGN Follow-up study with outcomes reported by patients three to six months after surgery. SETTING 25 ISTCs and 72 NHS providers in England. Population Consecutive patients undergoing hip or knee replacement (5671 in ISTCs and 14,292 in NH...

Methods: Two-dimensional kinematic gait pattern of 10 participants were collected before and after the TKR surgery, using a 60 Hz camcorder in sagittal plane. Then, the kinematic parameters were extracted using the gait data. A student t-test was used to compare the group-average of spatiotemporal and peak kinematic characteristics in the sagittal plane. The knee condition was also evaluated us...

BACKGROUND There are varieties of self-assessment questionnaire used for the evaluation of pain, functional disability, and health related quality of life in individuals with knee osteoarthritis (OA). The present study intended to adapt and translate the oxford knee score into the Arabic and investigated its psychometric properties in adult male with knee OA. METHODS Ninety-seven adult male (...

BACKGROUND We aimed to compare the performance of EQ-5D-3 L and howRu, which are short generic patient-reported outcome measures (PROMs), in assessing the outcome of hip and knee replacements, using the Oxford Hip Score (OHS) and the Oxford Knee Scores (OKS) for comparison. METHODS Outcome was assessed as the difference between pre-surgery and 6-month post-surgery scores. We used a large samp...

BACKGROUND AND PURPOSE Pain sensitization may be one of the reasons for persistent pain after technically successful joint replacement. We analyzed how pain sensitization, as measured by quantitative sensory testing, relates preoperatively to joint function in patients with osteoarthritis (OA) scheduled for joint replacement. PATIENTS AND METHODS We included 50 patients with knee OA and 49 wi...

PURPOSE OF THE STUDY The kinematics of an intact knee joint and that of a knee replacement have been studied in many research centres. In the 1987 radiographic study, Bradley, Goodfellow and O'Connor reported the movement of a polyethylene insert in patients with unicompartmental Oxford knee replacement. Views with the knee at full extension and 90° of flexion were obtained and the movement of ...

BACKGROUND It is unclear if there is a clinically important improvement in the six to 12-month recovery period after hip and knee replacement. This is an obvious gap in the evidence required by patients undergoing these procedures. It is also an issue for the English PROMs (Patient-Reported Outcome Measures) Programme which uses 6-month outcome data to compare the results of hospitals that perf...

The contraindications for unicompartmental knee replacement (UKR) remain controversial. The views of many surgeons are based on Kozinn and Scott's 1989 publication which stated that patients who weighed more than 82 kg, were younger than 60 years, undertook heavy labour, had exposed bone in the patellofemoral joint or chondrocalcinosis, were not ideal candidates for UKR. Our aim was to determin...

OBJECTIVE To evaluate the effect of obesity on total knee arthroplasty, and on patient-reported outcomes. METHODS The longitudinal study was conducted from September 2013 to August 2015 at The Second Hospital of Jinlin University, Changchun, Jinlin, China, a tertiary hospital. Using universal sampling method, all patients who underwent elective total knee arthroplasty were included in the stu...
