What are the treatment recommendations for a patient with severe glenohumeral osteoarthritis, biceps tendinosis, and supraspinatus tendinosis?

Treatment Recommendations for Severe Glenohumeral Osteoarthritis with Biceps and Supraspinatus Tendinosis

For severe glenohumeral osteoarthritis with concurrent biceps tendinosis and supraspinatus tendinosis, total shoulder arthroplasty (TSA) with biceps tenodesis is the definitive surgical treatment when conservative management fails, provided the rotator cuff is reparable. 1

Initial Conservative Management

Start with a structured trial of conservative treatment for 3-6 months, including:

• Physical therapy focused on range of motion and rotator cuff strengthening
• Pharmacotherapy with NSAIDs or acetaminophen for pain control
• Injectable corticosteroids (though evidence is limited for glenohumeral OA specifically) 1

The AAOS guidelines acknowledge that evidence for nonsurgical treatment of glenohumeral OA is extremely limited, with most recommendations extrapolated from hip and knee OA literature 1. However, given the severity of your case with multiple pathologies, conservative management may provide only temporary relief.

Surgical Decision-Making Algorithm

When Conservative Treatment Fails:

1. First, assess rotator cuff integrity:

• If the supraspinatus tendinosis represents a reparable tear or tendinopathy: Proceed with TSA
• If there is an irreparable rotator cuff tear: TSA is contraindicated; consider reverse shoulder arthroplasty instead 1, 2

2. For severe glenohumeral OA with reparable cuff pathology:

• Total shoulder arthroplasty is superior to hemiarthroplasty (moderate-strength recommendation) 1
• TSA provides better functional outcomes and pain relief compared to hemiarthroplasty in patients with intact or reparable rotator cuffs

3. Address the biceps tendinosis during arthroplasty:

• Perform biceps tenodesis at the time of TSA 3
• The suprapectoral onlay technique with either metal button or soft-body anchor fixation is safe and effective, with low complication rates (0.5% Popeye deformity, 3% persistent bicipital pain) 3
• Do not leave a diseased biceps tendon untreated, as biceps pathology is well-documented in association with glenohumeral arthritis 3

4. Manage the supraspinatus tendinosis:

• If the supraspinatus represents tendinosis without full-thickness tear: Address with debridement during TSA
• If there is a partial or full-thickness tear: Repair the rotator cuff at the time of arthroplasty 4
• Recent evidence suggests starting with exercise-based therapy for isolated supraspinatus tears, but in the context of severe glenohumeral OA requiring arthroplasty, concurrent repair is appropriate 4

Critical Surgical Considerations

Important Caveats:

• Surgeon volume matters: Avoid surgeons performing fewer than 2 shoulder arthroplasties per year, as this increases immediate postoperative complications 1
• VTE prophylaxis is mandatory: Use perioperative mechanical and/or chemical venous thromboembolism prophylaxis (consensus recommendation) 1
• Glenoid component selection: Consider keeled or pegged all-polyethylene cemented glenoid components (weak recommendation) 1

Prognostic Factors to Consider:

Patient comorbidities significantly impact outcomes after rotator cuff repair in the setting of glenohumeral OA:

• Obesity, diabetes, and tobacco use are associated with worse pain scores and patient-reported outcomes 5
• Moderate-to-severe OA (which you have) predicts worse postoperative range of motion and strength compared to mild OA 5
• These factors should inform your preoperative counseling but do not contraindicate surgery

Alternative Considerations

If the patient is younger (<55 years) and highly active, arthroscopic comprehensive management (debridement, synovectomy, capsular release, biceps tenodesis) may be considered as a joint-preserving alternative, though this is less established 6. However, given the severity described as "severe" glenohumeral OA, this approach is unlikely to provide durable relief.

If there is an irreparable rotator cuff tear (which must be ruled out), reverse shoulder arthroplasty becomes the treatment of choice, as TSA is contraindicated in this scenario 1, 2.

Postoperative Management

• Multimodal pain management using non-opioid modalities is supported by moderate evidence 2
• Immobilization should not exceed 3 weeks postoperatively 4
• Intensive rehabilitation with emphasis on range of motion and capsular mobility is essential 6

The key distinction in your case is determining whether the supraspinatus tendinosis represents a reparable pathology versus an irreparable tear, as this fundamentally changes the surgical approach from anatomic TSA to reverse TSA.
