Abstract

A randomised controlled trial of total resurfacing versus hemi resurfacing in the treatment of primary osteoarthritis of the shoulder.

Highlights

  • We found that there were rather few patients for whom shoulder resurfacing might be suitable

  • Shoulder resurfacing is a newer form of replacement where the anatomy is maintained as the head is not removed

  • Mid-term survival of shoulder resurfacing has been comparable to shoulder replacement (SR) in two national joint registries (New Zealand and Australia)

Summary

Objectives

The primary objective of the study was:● To quantify differences in functional and quality of life measures between total resurfacing and hemi resurfacing at one year post-operatively● The secondary objectives were: ● To estimate the distribution of outcome measures within a trial and compare with published observational studies. ● To determine the feasibility of the randomisation and trial processes. ● To evaluate the optimal sample size for a full trial. ● To determine the complication rate of total resurfacing versus hemi resurfacing at one year post-surgery. ● To estimate the likely cost difference and distribution of costs between total resurfacing and hemi resurfacing in order to inform a full trial.
