Background: Arthroscopic rotator cuff repair (ARCR) is among the most commonly performed orthopaedic procedures. Several factors-including age, sex, and tear severity-have been identified as predictors for outcome after repair. The influence of the tear etiology on functional and structural outcome remains controversial.

- The study investigates how psychosocial factors, sleep, and pain processing affect recovery outcomes after surgical rotator cuff repair (RCR), aiming to shift the focus from just biomedical factors like tear size.
- A cohort of 141 participants will be analyzed using various assessments before and after the surgery to establish relationships between these factors and recovery indicators, such as pain levels and quality of life.
- Findings will be shared at conferences and published in peer-reviewed journals to enhance understanding of holistic rehabilitation strategies for RCR recovery.
Problem: A suspected high proportion of unnecessary blood transfusions occur in patients undergoing total joint replacement.
Design: Prospective before and after study evaluating the impact of a one page flow chart aimed at reducing the use of blood transfusions.
Setting: Orthopaedic tertiary care centre in Winterthur, Switzerland.
Autologous blood donation in total knee arthroplasties is not necessary.
Acta Orthop Scand
February 2004
Background: This study intends to prove the hypothesis that preoperative autologous blood donation in total knee arthroplasties (TKA) is dispensable.
Patients And Methods: The study comprises a prospective analysis of 81 consecutive TKA without preoperative autologous blood donation (AB-donation). Guidelines for blood retransfusion were used.
Ganz reinforcement ring for reconstruction of acetabular defects in revision total hip arthroplasty.
J Bone Joint Surg Am
December 2003
Background: In revision total hip arthroplasty, bone loss due to loosening and migration of the acetabular component makes fixation of a new implant difficult. The purpose of this study was to evaluate the clinical and radiographic outcomes of the use of the Ganz reinforcement ring with nonstructural allograft in the reconstruction of acetabular defects.
Methods: Sixty-one acetabular revisions performed with use of the Ganz reinforcement ring and nonstructural allograft, between 1989 and 1992, in fifty-seven patients with aseptic loosening met our selection criteria.
