Conservative Rotator Cuff Treatment

Rehabilitation Management of Rotator Cuff Injuries in the Master Athlete

Rotator cuff (RTC) injuries are common in master athletes, especially overhead athletes. Risk factors include aging and degeneration as nonmodifiable and volume of activity, muscle weakness, and loss of motion as modifiable. The clinical presentation involves limited range of motion (ROM), pain at rest and at night. Injury classification into traumatic versus nontraumatic and tendinopathy, partial or full-thickness tears helps to establish a treatment plan. RTC injury rehabilitation protocols are criteria-based, multimodal, and divided into four phases. The acute phase addresses pain, inflammation, ROM, and RTC protection. The recovery phase addresses kinetic chain abnormalities, flexibility, and strength, and the functional phase involves exercises directed toward specific sport activities. Return to sports is based on clinical recovery, kinetic chain principles, and adequate sports technique. Nonsurgical management is recommended in most cases, and surgical management is considered if symptoms progress, especially for full-thickness tears.

Treatment for Rotator Cuff Tear Is Influenced by Demographics and Characteristics of the Area Where Patients Live

Background:

Atraumatic rotator cuff tear is a common orthopaedic complaint for people >60 years of age. Lack of evidence or consensus on appropriate treatment for this type of injury creates the potential for substantial discretion in treatment decisions. To our knowledge, no study has assessed the implications of this discretion on treatment patterns across the United States.

Methods:

All Medicare beneficiaries in the United States with a new magnetic resonance imaging (MRI)-confirmed atraumatic rotator cuff tear were identified with use of 2010 to 2012 Medicare administrative data and were categorized according to initial treatment (surgery, physical therapy, or watchful waiting). Treatment was modeled as a function of the clinical and demographic characteristics of each patient. Variation in treatment rates across hospital referral regions and the presence of area treatment signatures, representing the extent that treatment rates varied across hospital referral regions after controlling for patient characteristics, were assessed. Correlations between measures of area treatment signatures and measures of physician access in hospital referral regions were examined.

Results:

Among patients who were identified as having a new, symptomatic, MRI-confirmed atraumatic rotator cuff tear (n = 32,203), 19.8% were managed with initial surgery; 41.3%, with initial physical therapy; and 38.8%, with watchful waiting. Patients who were older, had more comorbidity, or were female, of non-white race, or dual-eligible for Medicaid were less likely to receive surgery (p < 0.0001). Black, dual-eligible females had 0.42-times (95% confidence interval [CI], 0.34 to 0.50) lower odds of surgery and 2.36-times (95% CI, 2.02 to 2.70) greater odds of watchful waiting. Covariate-adjusted odds of surgery varied dramatically across hospital referral regions; unadjusted surgery and physical therapy rates varied from 0% to 73% and from 6% to 74%, respectively. On average, patients in high-surgery areas were 62% more likely to receive surgery than the average patient with identical measured characteristics, and patients in low-surgery areas were half as likely to receive surgery than the average comparable patient. The supply of orthopaedic surgeons and the supply of physical therapists were associated with greater use of initial surgery and physical therapy, respectively.

Conclusions:

Patient characteristics had a significant influence on treatment for atraumatic rotator cuff tear but did not explain the wide-ranging variation in treatment rates across areas. Local-area physician supply and specialty mix were correlated with treatment, independent of the patient’s measured characteristics.
