Scottsdale Shoulder Answers

Each shoulder care choice serves a different need

Your exam helps choose the right care

Scottsdale’s busiest stretch runs from January through March. More activity can expose an ache that was building. An exam will find where movement feels weak or stiff.

Care won’t always begin with a treatment. You may first adjust a painful reach and rebuild strength. Medicine may also help some people move more easily.

A shoulder visit checks motion and strength

You’ll first tell the doctor what you were doing when soreness started. Show which reaches hurt or feel weak. The exam checks several ways your arm moves.

The person examining you may be a doctor, nurse, or therapist. They’ll compare your shoulders and may check your neck. Wear inside the joint may appear on an X-ray.

Take the names of the medicines you use. Mention falls, fever, numbness, and lost sleep. Don’t leave out a sudden loss of strength.

Name one daily task the shoulder now limits. That’ll give you a useful goal. Later, you can tell whether that task feels easier.

If soreness doesn’t settle, QC Kinetix can explain its options

QC Kinetix offers regenerative treatments, meaning non-surgical care prepared and given at the clinic. Its medical providers are the clinic team who’ll examine you. They’ll discuss the choices after checking your shoulder.

PRP means platelet-rich plasma. The clinic will separate this portion from your blood. The finished PRP has more platelets than ordinary blood.

Concentrated PRP is prepared with still more platelets. Ask which kind they’ll use for you. Also ask about total cost and return visits.

The consultation doesn’t cost you. Still, not every sore shoulder fits these treatments. Your exam may point to exercise, more tests, or surgery.

Medical studies don’t promise the same PRP result

Studies of sore shoulder cords don’t all agree. Some found modest relief around six months after PRP. Others didn’t find a change people could feel.

The cause of soreness changes the likely result. Results also differ by when people were checked. One study can’t answer for every shoulder problem.

Choose a change you can feel in daily life. Better sleep may matter more than a changed shoulder image. Easier reaching may matter more than a score.

Shoulder operations don’t all have the same aim. A repair mends a torn cord. Another operation loosens the tight covering around a frozen shoulder. Joint replacement swaps worn joint surfaces.

  1. The GRASP trial randomized 708 adults with a rotator cuff disorder to progressive exercise (up to 6 sessions), a single best-practice advice session, or either of those preceded by a corticosteroid injection. Over 12 months there was no evidence of a difference in Shoulder Pain and Disability Index between progressive exercise and one advice session (adjusted mean difference -0.66, 99% CI -4.52 to 3.20), and no evidence of a difference between having a corticosteroid injection and not having one.

  2. A 2025 meta-analysis of 15 randomized trials (1,785 participants) found corticosteroid injection ADDED to physical therapy produced small-to-moderate short-term improvements in pain and function, corticosteroid injection ALONE was not more effective than physical therapy, and at mid- and long-term follow-up corticosteroid was not more effective than physical therapy at all. Certainty of evidence was moderate to mostly very low.

  3. A 2026 meta-analysis of 10 randomized trials (n=591) found PRP and corticosteroid indistinguishable at 3-6 weeks and 3 months, with PRP pulling ahead at 6 months: ASES +10.8 (95% CI 4.71-16.80), Constant-Murley +10.7 (1.21-20.27) and VAS pain -0.8 (-1.45 to -0.18), plus fewer adverse events (RR 0.66, 0.44-0.99). The authors describe the benefit as statistically significant but CLINICALLY MODEST.

  4. A meta-analysis of nine randomized trials (469 patients) found corticosteroid superior to PRP in the SHORT term on Constant, Simple Shoulder Test and ASES scores, no difference at mid-term, and PRP superior in the LONG term on Simple Shoulder Test and ASES. The authors state explicitly that none of these differences reached the minimal clinically important difference.

  5. 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.

  6. FDA states verbatim that stem cell, stromal vascular fraction, umbilical cord blood, Wharton's jelly, amniotic fluid and exosome products 'have [not] been approved for the treatment of any orthopedic condition, such as osteoarthritis, tendonitis, disc disease, tennis elbow, back pain, hip pain, knee pain, neck pain, or shoulder pain.' The only FDA-approved stem cell products in the United States are blood-forming (hematopoietic progenitor) cells from umbilical cord blood, approved only for disorders of blood production, and there are currently NO FDA-approved exosome products.

  7. Medicare's national coverage policy covers autologous platelet-rich plasma ONLY for chronic non-healing diabetic, pressure and/or venous wounds, and only within an approved coverage-with-evidence-development study. There is no Medicare national coverage for PRP in shoulder osteoarthritis or rotator cuff disease, which is why these injections are billed to the patient directly.

  8. 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.

  9. 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).

  10. 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.

  11. The Cochrane review of manual therapy and exercise for rotator cuff disease included 60 trials and 3,620 participants but could perform no meta-analysis because of clinical heterogeneity and incomplete outcome reporting; risk of bias was high in 43 of the 60 trials. The single high-quality placebo-controlled trial (120 participants) found manual therapy plus exercise no better than inactive ultrasound at 22 weeks on overall pain.

Take your shoulder questions to the visit

If soreness hasn’t settled, note how it started. Include lost motion, weak reaches, and poor sleep. Those details will help during your exam.

Ask which choices fit your shoulder. Ask about cost and return visits, too. Don’t leave until you understand what happens next.
