Do I need shoulder surgery now?

When is it reasonable to wait?

Slow soreness with useful strength often gives you time to try home care. Reduce the reach that starts the ache, while keeping the arm moving gently. A doctor or physical therapist can set safe moves and build strength little by little. When sleep, reach, and strength improve, an operation won't always be the next choice.

Frozen shoulder is different because stiffness causes most of the trouble. A tough sleeve surrounds the ball and socket inside your shoulder. That sleeve can tighten, and someone else can't move the arm much farther. An exam can separate this stiffness from a torn tendon or worn joint surfaces.

What could a non-surgical visit add?

During a QC Kinetix visit, clinic staff check your motion and strength. Regenerative treatments there use your own blood or marrow, which staff prepare during clinic care. Platelet-rich plasma is blood spun to gather platelets, then placed by needle near the sore area. Bone marrow concentrate is marrow drawn from the pelvis, prepared, and placed at the shoulder.

These choices don't involve an operation, but they aren't the same as exercise. Ask about the steps, possible risks, cost, and the reason one may fit you. New weakness after an injury needs a quicker exam because a tendon may have torn. An arm that looks out of place also needs urgent care.

1. At 10 years, arthroscopic subacromial decompression offered NO benefit over placebo surgery for subacromial pain syndrome: the mean difference in VAS pain was -1.5 points (95% CI -8.6 to 5.6) at rest and -3.2 points (-13.0 to 6.5) on arm activity, against a minimally important difference of 15. It also showed no benefit over exercise therapy.

2. CSAW randomized 313 UK patients with at least 3 months of subacromial pain, intact cuff tendons and a failed non-operative programme to decompression surgery, placebo arthroscopy, or no treatment. Mean Oxford Shoulder Score at 6 months did not differ between the two surgical groups (32.7 versus 34.2; mean difference -1.3, 95% CI -3.9 to 1.3, p=0.31), meaning the bone-and-soft-tissue removal that defines the operation added nothing.

3. A systematic review with meta-analysis found HIGH certainty evidence of no additional benefit of subacromial decompression over placebo surgery for pain at 1 year (MD -0.26, 95% CI -0.84 to 0.33 against a MID of 1.5) and for physical function at 1-2 years (MD 2.8, -1.4 to 6.9 against a MID of 8.3), plus moderate certainty evidence of six serious harms per 1000 patients operated.

4. At 5 years, FIMPACT still showed no benefit of arthroscopic subacromial decompression over diagnostic arthroscopy: VAS pain differences of -2.0 at rest (95% CI -8.5 to 4.6) and -8.0 on arm activity (-17.3 to 1.3), neither exceeding the minimally important difference, and no advantage over exercise therapy either.

5. The Cochrane review of surgery for rotator cuff tears included nine trials and 1,007 participants; three of those trials (339 participants with MRI- or ultrasound-confirmed full-thickness tears) compared repair plus subacromial decompression followed by exercise against exercise ALONE. All included trials were at risk of bias on several criteria, most notably lack of participant and personnel blinding.

6. In the MOON Shoulder prospective cohort of 452 patients with symptomatic, ATRAUMATIC full-thickness rotator cuff tears, physical therapy succeeded in more than 70% of patients at 10 years: only 115 (27.0%) had surgery at any point over the decade. Patient-reported outcomes improved with physical therapy and did NOT decline over 10 years in those who never had surgery. The strongest predictor of early surgery was low patient expectation of physical therapy, not tear anatomy.

7. A meta-analysis of six randomized trials comparing conservative with surgical management of full-thickness rotator cuff tears found no statistically significant difference in Constant-Murley score at either 12 or 24 months (77.6 versus 72.8 at 12 months); surgery did show a statistically better VAS pain score at one year (-1.08, 95% CI -1.58 to -0.58).

8. A comparative longitudinal study of 83 non-operatively managed and 65 surgically repaired degenerative rotator cuff tears, matched at baseline for tear width, length and fatty degeneration, found significantly better final outcomes in the surgical group: median VAS pain 0 versus 3.5, composite ASES 95 versus 65.8, abduction strength 69.6 N versus 35.9 N, and greater forward elevation and external rotation (all p<=0.002). The groups were not randomized - the surgical group had failed non-operative treatment and was younger.

9. Repeat MRI in 122 patients treated non-operatively for a symptomatic supraspinatus tear found tear size increased in 41.8% overall, was unchanged in 53.3% and decreased in 4.9%. The split by tear type is the important part: 82.4% of FULL-thickness tears enlarged versus 26.1% of partial-thickness tears, making full-thickness tear the strongest predictor of progression.

10. A systematic review of nine randomized trials of primary frozen shoulder found that none of physiotherapy-with-steroid-injection, manipulation under anaesthesia or arthroscopic capsular release is clinically superior to the others; all standardized mean differences fell below the clinical-significance threshold agreed for UK FROST and most confidence intervals included zero. The evidence for HYDRODILATATION was inconclusive and remains a gap.

11. UK FROST randomized 503 adults with primary frozen shoulder to manipulation under anaesthesia, arthroscopic capsular release, or early structured physiotherapy with steroid injection. At 12 months every between-group difference on the Oxford Shoulder Score was smaller than the target difference, so NONE of the three was clinically superior. Capsular release carried the most serious adverse events (8 versus 2 with manipulation), and manipulation under anaesthesia was the most cost-effective.

12. A systematic review of seven case series (469 reverse total shoulder arthroplasties, mean age 71, mean 12-year follow-up) found weighted mean revision-free implant survivorship of 88% at 10 years, an overall complication rate of 36% and revision in 23% of patients - most often for infection (8%), instability (7%) and glenoid complications (3%) - alongside large functional gains (absolute Constant score 27 to 62).

13. An Australian national joint registry analysis of 1,564 shoulder arthroplasties done for osteoarthritis in patients UNDER 55 found reverse total shoulder arthroplasty had the lowest revision rate at mid-term follow-up; hemiarthroplasty resurfacing had a higher revision rate after one year (HR 2.51) and stemmed metallic-head hemiarthroplasty across the whole period (HR 2.69). Glenoid erosion drove revisions of resurfacing; instability drove revisions of reverse arthroplasty.
