Clinical Studies

At LRE System Ltd, we are dedicated to advancing the understanding of our product and the benefits to patients, surgeons and hospitals, through clinical studies and post market clinical evaluation.

Summary of LRE clinical evidence outcomes against safety and performance

  • 100% survivorship up to a maximum of 9.4 years (8.6 years mean; Watkins et al).
  • Overall complication rate reported in the literature of 6.3%. This compares well with complication rates for TEA reported in systematic reviews which showed complication rates ranging from 20-29%.
  • Clinical data demonstrates significant improvements in range of movement, consistent with the requirements for resumption of normal daily activity.
  • Statistically significant improvements in PROMS were reported in four retrieved articles, consistent with good to excellent performance outcomes.

Unicompartmental Elbow Replacement: Development of a Lateral Replacement Elbow (LRE) Arthroplasty

“The resulting lateral resurfacing elbow arthroplasty began clinical evaluation in September 2005 and to date has been inserted into 44 elbows (43 patients). The purpose of this article is to outline the design rationale, describe the surgical technique, and present the early results of the lateral resurfacing elbow arthroplasty.”

Long-term results of the lateral resurfacing elbow arthroplasty

“The aim of this study was to report the long-term outcome and implant survival of the lateral resurfacing elbow (LRE) arthroplasty in the treatment of elbow arthritis. We reviewed a consecutive series of 27 patients (30 elbows) who underwent LRE arthroplasty between December 2005 and January 2008. We found that the LRE arthroplasty, which was initially developed for younger patients with osteoarthritis, is an effective form of surgical treatment for a wider range of patients with more severe degenerative changes, irrespective of their cause.”
