# What an exam can tell you about joint soreness *What an exam can tell you | Joint Regeneration Gilbert* > Joint regeneration Gilbert guidance on what causes soreness, what an exam may find, and what to bring when the joint needs care. ## Why does this joint keep aching? Soreness alone can't tell you which part of the joint hurts. An exam shows which movement hurts, where motion stops, and whether strength has changed. Cartilage has little feeling, but the bone beneath worn cartilage can ache. The thin tissue lining the joint can also swell and feel sore. ## What to notice before the visit Notice whether soreness starts while moving, afterward, or after sitting still. Also note swelling, warmth, catching, weakness, and any shorter walking limit. A tendon joins muscle to bone and may hurt when the muscle tightens. You might notice that ache while lifting, climbing steps, or standing up from a chair. Check the joint on the morning after a busy day. Lasting soreness means that amount of work may still be too much. ## What to carry into your exam List your current medicines and when earlier joint care took place. Bring old X-rays and therapy notes if they're easy to find. Choose tasks that matter, such as sleeping, using stairs, or getting dressed. Clear examples help you and the doctor decide whether care made a useful difference. Ask the doctor to name the sore part and other possible causes. Then ask whether exercise, medicine, or another choice makes sense first. ## What to do when soreness doesn't ease Ongoing soreness needs another look when it keeps changing your daily routine. Get prompt care if the joint becomes hot, badly swollen, or painful with fever. When soreness doesn't ease, QC Kinetix in Chandler offers consultations about biologic therapies, meaning non-surgical shots prepared from blood or marrow, the soft center inside bone. A doctor first examines your joint and asks about earlier care. Human research doesn't promise rebuilt cartilage or the same relief for everyone. Ask how likely relief is for your joint and when it will be checked. You can also ask what comes next if the shot doesn't help. That answer helps you weigh the choice before care begins. ## Sources 1. 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.

DOI: 10.1001/jama.2021.19415. 2. A GRADE-rated systematic review and meta-analysis of 16 randomized trials (807 participants) found that MSC therapy for chronic knee OA pain PROBABLY RESULTS IN LITTLE TO NO DIFFERENCE in pain relief at 3-6 months (WMD -0.74 cm on a 10 cm VAS against a minimally important difference of 1.5 cm) or physical functioning (WMD 2.23 on the SF-36 100-point subscale against a 10-point MID), both moderate certainty; at 12 months pain was again probably little-to-no-different (WMD -0.73 cm). The measured effect is real but sits BELOW the threshold at which a patient would notice it.

DOI: 10.1016/j.joca.2024.04.021. 3. A Level-1 systematic review of 8 randomized trials (937 patients) of bone marrow aspirate concentrate for knee OA found BMAC improved clinical scores versus baseline from one month, and beat hyaluronic acid on pain at 6 and 12 months with statistical significance - but those differences DID NOT EXCEED the minimal clinically important difference, and against other injections no significant difference appeared at all. Statistically detectable is not the same as noticeable.

The overall MIBO score was 72%, 71% of studies scored below 80%, and reporting was worst on exactly the items that define the product: whole-blood characteristics (20%), platelet recovery rate (22%), PRP analysis (30%), PRP activation (47%). Adherence did not improve after MIBO was published. Much of the PRP literature does not say what was actually injected.

A JBJS systematic review screened 420 papers on intra-articular cellular therapy for knee OA and focal cartilage defects and found only SIX at Level III evidence or higher (4 Level II, 2 Level III), covering 300 knees, with wide variation in cell source, cell characterisation, adjuvant therapy and outcome assessment - meaning no consensus exists on indications, cell sources, preparation or delivery. Two products called 'stem cell therapy' at two clinics may share almost nothing.

American volume*, 2016. DOI: 10.2106/JBJS.15.01495. 6. FORWARD, the longest disease-modifying osteoarthritis drug trial reported to date, gave intra-articular sprifermin (a recombinant FGF-18) or placebo to knee OA patients and followed 378 of them for 5 years. Sprifermin produced a significant, sustained dose-response INCREASE in total femorotibial cartilage thickness versus placebo - and WOMAC pain improved about 50% from baseline in ALL groups, including placebo. It is the cleanest demonstration in the literature that adding measurable cartilage and relieving pain are two different results, and that one does not deliver the other.

A doctor examines your joint before discussing the choices. Bring old X-rays and soreness notes, plus a current list of medicines. Call (602) 837-PAIN when you're ready to ask about an appointment. Ask what the shot contains, what it costs, and what relief is reasonable. You don't need to decide before those questions are answered. Book an appointment: --- Clear help for a sore joint.
