Treatment of Massive Irreparable Rotator Cuff Tears: A Cost-effectiveness Analysis.
Massive irreparable rotator cuff tears cause significant shoulder pain and dysfunction. Physical therapy (PT), arthroscopic debridement with biceps tenotomy (AD-BT), and hemiarthroplasty (HA) are treatments shown to reduce pain and improve quality of life. Reverse total shoulder arthroplasty (RTSA) is a newer surgical treatment option that may offer improved function. A cost-effectiveness analysis of these interventions has never been performed, and no head-to-head comparative effectiveness trials currently exist. A Markov decision analytic model was used to compare RTSA, HA, AD-BT, and PT as treatments for elderly patients with massive irreparable rotator cuff tears. Probabilities for complications, perioperative death, conversion procedures, and reoperations were derived from the literature, and costs were determined by average Medicare reimbursement rates from 2011. Reverse total shoulder arthroplasty yielded the most quality-adjusted life years (QALY) with 7.69, but greater benefits came at higher costs compared with other treatments. Sensitivity analyses showed that PT was the most cost-effective intervention at a health utility of 0.75 or greater (QALY 7.35). The health utility of RTSA was 0.72 or less (QALY 7.48) or RTSA probability of no complications was 0.83 or less (QALY 7.48 at cost of $23,830). Reverse total shoulder arthroplasty yielded benefits at a cost considered good value for money compared with other treatments. Reverse total shoulder arthroplasty is the preferred and most cost-effective treatment option for elderly patients with massive irreparable rotator cuff tears. For patients seeking pain relief without functional gains, AD-BT can be considered a cost-effective and cheaper alternative. The cost-effectiveness analysis approach can help guide clinical practice as well as the policies of health care systems and insurers. [Orthopedics. 2017; 40(1):e65-e76.].
