Low-term results from non-conventional partial arthroplasty for treating rotator cuff arthroplasthy

Area of Science:

• Orthopedic Surgery
• Biomaterials Science

Background:

• Degenerative rotator cuff arthropathy often necessitates surgical intervention when conservative treatments fail.
• The CTA hemiarthroplasty is a surgical option for managing severe rotator cuff disease.

Purpose of the Study:

• To assess the long-term functional results and patient satisfaction following CTA hemiarthroplasty for degenerative rotator cuff arthropathy.
• To evaluate the evolution of functional outcomes with a mean follow-up of 5.4 years.

Main Methods:

• A cohort of 18 patients with degenerative rotator cuff arthropathy underwent CTA hemiarthroplasty.
• Pre and postoperative functional assessments included the University of California in Los Angeles (UCLA) score and range of motion.
• Exclusion criteria included prior shoulder surgery, pseudoparalysis, and specific anatomical or muscular insufficiencies.

Main Results:

• At a mean follow-up of 5.4 years, 78% of patients reported satisfaction with the CTA hemiarthroplasty.
• Significant improvements were observed in active elevation (55.8° to 82.0°) and external rotation (18.9° to 27.3°).
• The mean UCLA score improved postoperatively and was maintained at the 5.4-year follow-up.

Conclusions:

• CTA hemiarthroplasty demonstrates sustained satisfactory functional results in carefully selected patients with rotator cuff arthropathy.
• The procedure offers a viable solution for improving shoulder function and patient satisfaction in the long term.
