Randomized Controlled Trial Comparative StudyContinuous infiltration of local anaesthetic following total knee arthroplasty.
To determine whether continuous infiltration of local anaesthetic can reduce the pain score and morphine use over 48 hours after total knee arthroplasty (TKA). ⋯ Continuous infiltration of local anaesthetic into the intra-articular space and subcutaneous tissues, in addition to PCA with intravenous morphine, provides significantly more pain relief and reduces morphine use.

Multicenter Study Comparative StudyDifferences in outcome between Maori and Caucasian patients undergoing total joint arthroplasty for osteoarthritis.
To compare differences in outcome between Maori and Caucasian patients undergoing total joint arthroplasty for osteoarthritis. ⋯ Maori patients were more likely than Caucasian patients to have preoperative comorbidities, but their postoperative length of hospital stay and complication rates were not significantly different.

Comparative StudyA multidisciplinary rehabilitation programme for patients with chronic low back pain: a prospective study.
To examine the effectiveness of a multidisciplinary rehabilitation programme for patients with chronic low back pain in Hong Kong, and to identify factors associated with work resumption. ⋯ This rehabilitation programme facilitated regain of physical functioning and the ability to return to work. The pre-programme employment status, duration of absence from work, and patient age were the most important predictors for work resumption.

Comparative StudyMid- to long-term outcome of cementless total hip arthroplasty in younger patients.
To assess mid- to long-term outcomes of cementless primary total hip arthroplasty (THA) in younger patients. ⋯ In younger patients undergoing THA, rates of polyethylene wear and pelvic osteolysis are high, and thus long-term follow-up is crucial.

Case ReportsPseudoaneurysm and intramuscular haematoma after dynamic hip screw fixation for intertrochanteric femoral fracture: a case report.
We report the case of an 83-year-old woman who developed a pseudoaneurysm of the profunda femoris artery after dynamic hip screw fixation for an intertrochanteric femoral fracture. 23 days after the fixation, radiological investigations including colour Doppler ultrasonography and computed tomographic angiography identified a pseudoaneurysm surrounded by a large intramuscular haematoma close to the profunda femoris. The patient underwent emergency evacuation and was under intensive care for 3 days and was discharged 6 weeks later, with no complications. At one-year follow-up, the wound and fracture had healed, but the patient was confined to a wheelchair. A high index of clinical suspicion and radiological imaging are necessary for making the diagnosis.
