Rotator cuff soreness often improves with the right exercise

A scan does not decide care by itself

A scan often shows cuff wear later in life. Some tears appear even when that shoulder doesn’t hurt.

The person examining you compares the scan with your strength and motion. How the soreness began matters just as much.

A scan is like seeing one side of a box. Your exam shows whether the tear matches your soreness.

New weakness after a fall makes a scan more useful. The result matters when it could change your care.

Steady exercise can restore useful shoulder motion

Begin with movement you can manage without a sharp flare. Then build strength around the shoulder blade and cuff.

You’ll need time to see whether motion and strength improve. Rest alone can leave your shoulder stiff and still weak.

Tell the therapist which daily task matters to you. Reaching a shelf needs different work than lifting or swinging.

Don’t keep doing the same exercise if weakness grows. Return for another exam and ask whether a scan now helps.

A sudden tear may need a quicker surgery talk

A fall followed by major weakness needs care soon. A complete new tear may need an earlier surgery decision.

Surgery may also come up when useful strength doesn’t return. Your health, tear size, daily needs, and recovery time all matter.

Platelet-rich plasma (PRP) is a portion prepared by spinning your blood. During surgery, it may go near the repaired tendon.

The surgeon has already joined that torn tendon back to bone. PRP used alone doesn’t do that repair.

Ask whether waiting could change your choices. You need a direct answer about recovery and other care.

1. The August 2025 AAOS Evidence-Based Clinical Practice Guideline on Management of Rotator Cuff Injuries issued 25 recommendations and 4 consensus statements. Among its updates it clearly RESTRICTS the use of platelet-rich plasma and marrow stimulation in rotator cuff repair, limits prolotherapy in full-thickness tears, establishes CT as an adjunctive imaging modality, and endorses early mobilization after repair of small-to-medium tears.

2. 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.

3. A meta-analysis of nine randomized trials (n=629) in partial-thickness rotator cuff tears and tendinopathy found statistically significant SHORT-term (6 +/- 1 months) PRP effects on pain (MD -1.56), Constant-Murley (+16.48) and SPADI (-18.78), but NO long-term effect on pain or function except Constant-Murley - i.e. the benefit may not last.

4. A randomized crossover trial of 51 patients compared percutaneous bone marrow concentrate plus platelet products with a HOME exercise programme for high-grade partial and full-thickness supraspinatus tears. The BMC group reported significantly greater improvement at three months (median change in DASH -11.7 versus -3.8; SANE +50.0 versus 0.0) with no serious adverse events. The comparator was an unsupervised home programme rather than supervised therapy or a sham injection, and patients could cross over at three months - so this is not a placebo-controlled result.

5. A network meta-analysis of randomized trials found double-row repair combined with platelet-rich plasma optimized retear rates after small-to-medium full-thickness rotator cuff repair - a result about SURGICAL TECHNIQUE plus augmentation, which is a different question from whether an injection of PRP helps an unoperated shoulder.
