Randomized Controlled Trial Comparative StudyInvestigation of the use of drained blood reinfusion after total knee arthroplasty: a prospective randomised controlled study.
To compare the use of a blood salvage and reinfusion system with standard allogeneic blood transfusion after total knee arthroplasty--a procedure associated with significant postoperative blood loss. ⋯ Postoperative reinfusion of drained blood reduced the need for blood transfusion after total knee arthroplasty, while having an effect on postoperative haemoglobin level equivalent to standard allogeneic blood transfusion.

Case ReportsAcetabular augmentation using a second cup during revision hip arthroplasty: an unusual case report.
Acetabular wedge augmentation is a useful technique and is recommended in situations where cup revision is likely to be excessively difficult. Numerous augmentation designs that improve the stability of the hip are now available in the market. ⋯ We report our experience in treating such a case, using an augment cut from a second cup with a follow-up for 30 months. Though there is no substitute for proper preoperative planning, awareness of this procedure is helpful as unexpected problems do arise in revision acetabular surgery.

Comparative Study Clinical TrialComparing 2-year outcomes of anterior cruciate ligament reconstruction using either patella-tendon or semitendinosus-tendon autografts: a non-randomised prospective study.
To compare the results of anterior cruciate ligament (ACL) reconstructions using either a patella-tendon autograft or a semitendinosus-tendon autograft. ⋯ ACL reconstruction is associated with a significantly better IKDC knee score and laxity measurement at 2-year follow-up. However, we were unable to demonstrate a significantly better long-term outcome in knee score or laxity to anterior translation with either a patella-tendon autograft or a semitendinosus-tendon autograft.

Case ReportsTophaceous gout causing atlanto-axial subluxation mimicking rheumatoid arthritis: a case report.
This is a case report of an extremely rare condition of atlanto-axial subluxation secondary to gouty arthritis, which mimicked rheumatoid arthritis at presentation. Gouty arthritis involving the spine is a rare condition. We highlight a case of gouty arthritis involving the atlanto-axial joint resulting in joint instability, subluxation, and neurological deficit. ⋯ However, after an initial neurological improvement, she succumbed to aspirational pneumonia and septicaemia. Atlanto-axial subluxation caused by gouty arthritis can present in the same way as rheumatoid arthritis. Therefore, the possibility of this as a differential diagnosis should be kept in mind.

Case ReportsBilateral spontaneous rupture of Achilles tendons: a case report.
Spontaneous bilateral rupture of Achilles tendon is rare. Rupture of the Achilles tendon has been described in patients on oral corticosteroid therapy. ⋯ This case is unusual because the patient has never taken steroids. We discuss the mechanism of injury and other probable causes.
