Massive Rotator Cuff Tears in Patients Older Than Sixty-five: Indications for Cuff Repair versus Reverse Total Shoulder Arthroplasty

Author and Disclosure Information

TAKE-HOME POINTS

  • Rotator cuff repair and reverse total shoulder arthroplasty are both viable options for patients >65 years with massive rotator cuff tears without arthritis.
  • Treatment must be individualized for each patient, with careful consideration of a number of preoperative variables and patient characteristics.
  • At our institution, patients with previous rotator cuff repair, decreased range of motion, poor function, and strong radiographic evidence of subluxation were more likely to undergo reverse total shoulder arthroplasty.
  • Patients selected for rotator cuff repair had greater preoperative flexion, abduction, and external rotation, as well as higher functional scores, and were less likely to have had previous cuff surgery.
  • When chosen appropriately, both rotator cuff repair and reverse total shoulder arthroplasty can result in improved range of motion, function, and high patient satisfaction in this patient population.

ABSTRACT

The decision to perform rotator cuff repair (RCR) versus reverse total shoulder arthroplasty (rTSA) for massive rotator cuff tear (MCT) without arthritis can be difficult. Our aim was to identify preoperative variables that are influential in a surgeon's decision to choose one of the two procedures and evaluate outcomes.

We retrospectively reviewed 181 patients older than 65 who underwent RCR or rTSA for MCT without arthritis. Clinical and radiographic data were collected and used to evaluate the preoperative variables in each of these two patient populations and assess outcomes.

Ninety-five shoulders underwent RCR and 92 underwent rTSA with an average followup of 44 and 47 months, respectively. Patients selected for RCR had greater preoperative flexion (113 vs 57), abduction (97 vs 53), and external rotation (42 vs 32), higher SST (3.1 vs 1.9) and ASES scores (43.8 vs 38.6), and were less likely to have had previous cuff surgery (6.3% vs 35.9%). Patients selected for rTSA had a smaller acromiohumeral interval (4.8 vs 8.7) and more superior subluxation (50.6% vs 14.1%). Similar preoperative characteristics included pain, comorbidities, and BMI. Patients were satisfied in both groups and had significant improvement in motion and function postoperatively.

Both RCR and rTSA can result in significant functional improvement and patient satisfaction in the setting of MCT without arthritis in patients older than 65. At our institution, patients who underwent rTSA had less pre-operative motion, lower function, more evidence of superior migration, and were more likely to have had previous rotator cuff surgery.
