When does your sore joint need an exam?

When is a regular visit worthwhile?

Arrange an exam if soreness returns or limits normal life. Night aches, repeated swelling or increasing weakness also deserve attention. There's no need to wait until the joint stops working.

The exam checks what the joint can do.

Your doctor will ask what motion hurts. The doctor checks tender areas, strength, swelling and movement. An X-ray can show wear, though it can't explain every ache.

What happens at a QC Kinetix consultation?

At QC Kinetix, a medical provider performs your exam and any care. They'll ask what daily task matters most. They'll also review past care and your health.

If clinic care may fit, they'll explain regenerative treatments made with plasma from spun blood or cells concentrated from bone marrow. A clinician places the prepared part in your sore joint. The exam may instead point to other care.

Take a current list of every medicine and any old X-ray report. Mention blood thinners, recent illness and past reactions. Those details help the clinic judge what's safe.

What do you need to ask before agreeing?

Have the clinician explain the exam findings in plain words. Then ask what change you might notice at home. Request the total price. Find out how much follow-up time is needed.

Before you agree to treatment, or give consent, learn what'll happen and what the risks are.

Learn what comes next when the care doesn't help. You'll need to know which symptoms require a call that day. If a reply doesn't address your sore joint, say, “How does that answer apply to my joint?”

1. The Cochrane review of exercise for knee osteoarthritis found high-quality evidence that land-based therapeutic exercise provides short-term benefit in pain and physical function, sustained for at least 2-6 months after the programme ends, with mild transient soreness the only reported adverse effect across 45 trials. It is the best-evidenced treatment for this condition and it costs nothing per injection.

2. A randomized trial in the New England Journal of Medicine compared physical therapy against intra-articular glucocorticoid injection for knee osteoarthritis and found physical therapy produced better WOMAC outcomes at one year. When a clinic offers an injection, the comparator that matters is not 'nothing' - it is a course of supervised exercise.

3. The RESTORE trial - a participant-, injector- and assessor-blinded RCT of 288 adults aged 50+ with symptomatic medial knee OA (Kellgren-Lawrence 2-3) - compared three weekly intra-articular PRP injections against saline placebo, with co-primary endpoints of 12-month knee pain and medial tibial cartilage volume on MRI. PRP did not beat placebo on either. It is the single best-designed test of the specific claim that PRP changes joint structure, and it was negative.

4. A four-arm, multicentre, single-blind phase 2/3 randomized trial of 480 knee OA patients (KL II-IV) compared autologous bone marrow aspirate concentrate, autologous adipose stromal vascular fraction and allogeneic umbilical-cord-tissue mesenchymal stromal cells against a corticosteroid injection control. At 12 months NONE of the three orthobiologic injections was superior to another, or to the corticosteroid control, and none of the four groups showed a significant change in MRI osteoarthritis score from baseline. No procedure-related serious adverse events occurred.

5. A 2026 systematic review and meta-analysis of 28 randomized trials of intra-articular mesenchymal stem cell-based therapies in knee OA found significant improvements in several pain and function measures (delta-VAS MD -1.67; KOOS pain MD 15.37) but NO significant difference in WOMAC, KOOS quality of life or the Lequesne index, and MRI-based WORMS scores were non-significant - indicating no consistent structural benefit. Its own conclusion: these therapies serve a primarily SYMPTOM-modifying rather than STRUCTURE-modifying role, with higher frequencies of local reactions to weigh against the symptomatic benefit.

6. MACI (autologous cultured chondrocytes on a porcine collagen membrane, Vericel; STN BL 125603) IS an FDA-LICENSED cell therapy - and its approved indication is narrow and specific: repair of symptomatic, single or multiple FULL-THICKNESS cartilage defects OF THE KNEE, with or without bone involvement, in adults. It is not approved for osteoarthritis. The existence of one licensed cartilage cell therapy for focal defects is the sharpest available way to show what a licensed 'regeneration' product actually looks like, and how far it is from an injection for a worn joint.

8. A cross-sectional study contacted 273 of 317 US centres offering direct-to-consumer stem-cell therapy, posing as a 57-year-old man with knee osteoarthritis. The mean advertised price of a unilateral same-day stem-cell knee injection was $5,156 (SD $2,446), and centres claimed a mean clinical efficacy of 82% (SD 9.6%) - a figure with no support in the published evidence. The gap between the quoted number and the trial data is the single most useful thing a patient can be told before a consultation.

Medicare's National Coverage Determination covers autologous platelet-rich plasma ONLY for chronic non-healing diabetic, pressure or venous WOUNDS, and only under Coverage with Evidence Development inside an approved clinical research study. There is no Medicare coverage pathway for PRP as a treatment for osteoarthritis or any other joint indication, which is why these injections are quoted as cash prices.

10. FDA states plainly that no stem cell, exosome, stromal vascular fraction, umbilical cord blood, Wharton's jelly or amniotic-fluid product has been approved for the treatment of ANY orthopedic condition - it names osteoarthritis, tendonitis, disc disease, tennis elbow, back pain, hip pain, knee pain, neck pain and shoulder pain individually. The only FDA-approved stem cell products in the United States are cord-blood-derived blood-forming stem cells for disorders of the hematopoietic system, and there are currently no FDA-approved exosome products.
