# Why does each joint hurt differently? *Joint Help | Regenerative Therapy Queen Creek* > Regenerative therapy Queen Creek guidance for knee, hip, shoulder and ankle soreness, with likely causes and useful next steps. ## Which movement bothers your joint? Start by naming the motion that hurts most. Notice whether the soreness began slowly or after one event. It'll help a doctor choose the right exam. Your shoulder and knee do different work. The sore spot also matters. Swelling, weakness and lost motion add more useful facts. Don't choose care only because it helped a different joint. ## Why do knees and hips get sore? Knee soreness often grows with stairs or long walks. Arthritis can bring aching, swelling and stiffness after rest. A recent twist calls for a different check. Hip soreness may sit in the groin or outer hip. It can bother you while walking or standing. Your back can also send an ache toward the hip. The doctor checks motion, strength, swelling and sore spots. An X-ray can reveal wear. Your symptoms tell the doctor how that wear affects daily life. ## Why do shoulders and ankles get sore? Shoulders often hurt during reaching or lifting. The tough band from muscle to bone is a tendon. It may be sore, or the joint may have arthritis. Sudden weakness after an injury needs an exam. An ankle can swell after a twist or too much walking. An old injury won't always heal without stiffness. Knee care won't answer every ankle problem. At QC Kinetix, a medical provider is the clinic worker checking you and giving care. You'll hear about non-surgical choices only after that exam. The choice needs to suit both the joint and findings. ## Can cartilage regeneration rebuild a worn joint? Cartilage makes a smooth cap over bone ends inside the joint. Office care hasn't reliably grown that cap back after arthritis wears it. Feeling less sore doesn't prove the joint surface changed. The catch is simple. Be careful with any claim that office care rebuilds a worn joint. Regenerative treatments use a prepared blood part or cells gathered from marrow. You may hear the word orthobiologics for this body-based joint care. Ask what they'll take, where it'll go and what change you may feel. ## Sources 1. A randomized controlled study of 111 patients aged 18-65 with hip osteoarthritis compared three weekly ultrasound-guided injections of PRP, hyaluronic acid, or both. PRP had the lowest VAS at every follow-up and beat HA significantly at 6 months (mean VAS 21 vs 44). But the WOMAC advantage present at 2 and 6 months was NO LONGER significant at 12 months, and the combination arm did worse than PRP alone. Dallari D, et al. — [Ultrasound-Guided Injection of Platelet-Rich Plasma and Hyaluronic Acid, Separately and in Combination, for Hip Osteoarthritis: A Randomized Controlled Study.](https://pubmed.ncbi.nlm.nih.gov/26797697/). *The American journal of sports medicine*, 2016. DOI: 10.1177/0363546515620383. 2. The PRIMA trial randomized 100 patients with ankle osteoarthritis to two ultrasound-guided intra-articular PRP injections or saline placebo. AOFAS scores improved 10 points with PRP (63 to 73) and 11 points with placebo (64 to 75); the adjusted between-group difference over 26 weeks was -1 (95% CI -6 to 3, p=0.56). The authors state the results do not support using PRP for ankle osteoarthritis. The evidence for a biologic in one joint does not transfer to another.

DOI: 10.1001/jama.2021.16602. 3. A systematic review and meta-analysis of randomized trials found that augmenting arthroscopic rotator cuff repair with platelet-rich plasma reduces the retear rate and improves clinical function scores, whereas platelet-rich FIBRIN gives no clinically meaningful benefit - with the authors cautioning about the small number and heterogeneity of studies. The shoulder's best biologic evidence is for PRP used ALONGSIDE a repair operation, not as a substitute for one.

A pairwise and network meta-analysis of 18 randomized trials in rotator cuff TENDINOPATHY found corticosteroid helps at 3-6 weeks but not beyond 24 weeks, while PRP and prolotherapy may yield better outcomes in the long term (over 24 weeks) - with the authors warning that heterogeneity requires cautious interpretation. Tendon and joint-surface problems do not behave the same way, and a shoulder page should not borrow knee-OA evidence.

Hyaluronic acid showed a small effect on pain and function in KNEE OA but not in hip OA or shoulder capsulitis; intra-articular glucocorticoid showed small effects in knee OA and on function in hip OA and shoulder capsulitis; PRP showed benefit in knee OA but NOT in hip OA, and mesenchymal stem cells behaved similarly. Overall conclusion: most intra-articular therapies exert SMALL effects and are well tolerated.

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.

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.

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.

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.
