Arthroplasty in the Valgus Knee: Comparison and Discussion of Lateral vs Medial Parapatellar Approaches and Implant Selection.

Constrained implants are frequently used for primary total knee arthroplasty (TKA) in patients with moderate and severe genu-valgum (>10˚).

Changing transfusion practice in total hip arthroplasty: observational study of the reduction of blood use over 6 years.

Patients undergoing primary total hip arthroplasty (THA) have historically been over-transfused. In a district general hospital setting, the authors observed a significant downward trend in blood transfusion requirements in these patients over 6 years after a change in transfusion policy. The purpose of this study was to retrospectively analyze the change in transfusion practice and present the results of the restrictive transfusion policy.
