# Does PRP work the same for every sore joint? *PRP Injections Queen Creek — Does PRP Work for Every Joint?* > PRP injections Queen Creek evidence made simple for sore knees, hips, elbows and Achilles tendons, with clear limits. Start with the body part that hurts before judging PRP. A tendon, the strong cord joining muscle to bone, works differently from a joint. Help found for an elbow may not apply to your knee. Human studies give mixed answers, with better support for some sore areas than others. Clinics also prepare blood differently and compare PRP with different care. Your exam still has to come before a treatment choice. ## What do studies say about a sore outer hip? In one human study, people with a lasting sore cord beside the hip reported less trouble with soreness and daily movement later. They had a clearly found cord problem without a full tear. The finding doesn't cover every cause of hip soreness. Joint wear, back trouble, and a strained cord can all hurt near the hip. A medical provider must find which part is sore before discussing PRP. QC Kinetix may offer concentrated PRP, meaning treatment prepared on site from your blood, when the exam finds a possible fit. ## Why do elbow and Achilles results differ? In some human elbow studies, people had milder soreness and easier use months later, although early results were alike. Human studies of lasting Achilles soreness have been less hopeful. They haven't found reliable help from PRP for a long-term problem or a fresh tear. A pop followed by lost push-off strength may mean the cord has torn. That needs a prompt exam because waiting can limit later care choices. PRP can't replace an exam for a tear or another injury. ## What do mixed knee results mean for you? After PRP, some people in human knee studies reported milder soreness or easier use. A large careful study found no clear gain over salt water. Studies differed in their platelet mixtures, the amount of joint wear, and the other care being compared. The human evidence for knees is uncertain. Exercise, weight change when needed, bracing, and common medicines may still help before PRP is considered. Ask whether a knee study included joint wear like yours and people who had tried similar care. ## Sources 1. A randomized double-blind trial of 80 patients with chronic gluteal tendinopathy (lateral hip pain) compared a single ultrasound-guided PRP injection with a single corticosteroid injection. At 12 weeks the PRP group had significantly better modified Harris Hip Scores (P=.048), and 82% versus 56.7% of patients reached the minimal clinically important difference (P=.016).

DOI: 10.1177/0363546517745525. 2. Two-year follow-up of the same 80-patient gluteal tendinopathy trial found the single leukocyte-RICH PRP injection produced improvement that was sustained at 104 weeks (mHHS 53.77 at baseline to 82.59 at two years; P<.0001), whereas the corticosteroid improvement peaked at six weeks and was not maintained beyond 24 weeks. This is one of the clearest demonstrations that leukocyte-rich PRP is the formulation with evidence in TENDON, not in cartilage.

DOI: 10.1177/0363546519826969. 3. A 12-centre randomized controlled trial of 230 patients with chronic lateral epicondylar tendinopathy compared tendon needling with leukocyte-enriched PRP against tendon needling alone. At 12 weeks there was no significant difference (55.1% versus 47.4% pain improvement; P=.163). At 24 weeks the PRP group reported 71.5% versus 56.1% pain improvement (P=.019), a 83.9% versus 68.3% success rate (P=.037), and significantly less residual elbow tenderness (29.1% versus 54.0%; P=.009). No significant complications occurred in either group.

A meta-analysis of 20 trials (1268 participants) covering elbow epicondylitis and plantar fasciitis found that for epicondylitis PRP gave a statistically and clinically meaningful long-term improvement in pain versus corticosteroid, with a very large effect size of -1.3 (95% CI -1.9 to -0.7), but the evidence level was LOW; there was moderate evidence that corticosteroid gave better short-term (1-3 month) pain relief than PRP.

A 24-site, 240-patient participant-blinded randomized trial of a single intratendinous PRP injection versus a sham (subcutaneous dry needle) for chronic midportion Achilles tendinopathy found VISA-A scores of 54.4 versus 53.4 at six months (adjusted mean difference -2.7; 95% CI -8.8 to 3.3) against a 12-point minimal clinically important difference. The authors stated the findings do not support the use of this treatment for chronic midportion Achilles tendinopathy.

DOI: 10.1001/jama.2021.6986. 6. PATH-2 randomised 230 adults with acute Achilles tendon rupture managed non-surgically to PRP or a placebo dry-needle injection across 19 UK hospitals, with a central laboratory confirming the PRP was of good quality with the expected growth-factor content. At 24 weeks there was no detectable difference in muscle-tendon function (limb symmetry index 34.7% versus 38.5%; adjusted mean difference -3.9%; 95% CI -10.5% to 2.7%) or in any secondary outcome or adverse-event rate. Keene DJ, Alsousou J, Harrison P, et al. — [Platelet rich plasma injection for acute Achilles tendon rupture: PATH-2 randomised, placebo controlled, superiority trial](https://pubmed.ncbi.nlm.nih.gov/31748208/). *BMJ*, 2019. DOI: 10.1136/bmj.l6132. 7. An updated meta-analysis of six randomized trials (422 patients) found no benefit of PRP over placebo for Achilles tendinopathy on VISA-A at 3 months (mean difference 1.7; 95% CI -1.8 to 5.2), 6 months (0.5; 95% CI -8.5 to 9.3) or 1 year (-7.9; 95% CI -27.3 to 11.6), nor on VAS pain at 3 months. Funnel-plot asymmetry suggested publication bias inflating apparent benefits. The authors wrote that PRP should not be used to treat Achilles tendinopathy until high-quality trials show a clear clinical benefit.

In the RESTORE trial - the largest placebo-controlled PRP trial in knee osteoarthritis - 288 adults aged 50+ with symptomatic Kellgren-Lawrence grade 2-3 medial knee OA received three weekly intra-articular injections of leukocyte-poor PRP from a commercial system or saline placebo. At 12 months the mean change in knee pain was -2.1 points with PRP versus -1.8 with saline (difference -0.4; 95% CI -0.9 to 0.2; P=.17) against a minimum clinically important difference of 1.8, and the change in medial tibial cartilage volume was -1.4% versus -1.2% (difference -0.2%; 95% CI -1.9% to 1.5%; P=.81). Twenty-nine of 31 prespecified secondary outcomes showed no significant between-group difference. The authors concluded the findings do not support use of PRP for knee OA. Bennell KL, Paterson KL, Metcalf BR, et al. — [Effect of Intra-articular Platelet-Rich Plasma vs Placebo Injection on Pain and Medial Tibial Cartilage Volume in Patients With Knee Osteoarthritis: The RESTORE Randomized Clinical Trial](https://pubmed.ncbi.nlm.nih.gov/34812863/). *JAMA*, 2021. DOI: 10.1001/jama.2021.19415. 9. The ESSKA-ICRS consensus applied the RAND/UCLA appropriateness method to 216 clinical scenarios for intra-articular PRP in knee OA. Only 84 scenarios (38.9%) were rated appropriate, 9 (4.2%) inappropriate and 123 (56.9%) uncertain. PRP was judged appropriate in patients aged 80 or under with KL grade 0-III osteoarthritis AFTER failed conservative non-injective or injective treatment; it was NOT considered appropriate as a first treatment, nor in KL grade IV (bone-on-bone) osteoarthritis, where 91.7% and 87.5% of scenarios respectively were uncertain.

DOI: 10.1002/ksa.12320. 10. The Cochrane review of exercise for knee osteoarthritis found low- to moderate-certainty evidence that exercise probably improves pain, physical function and quality of life in the short term - but when the results were compared against established minimal important difference thresholds (12 points for pain, 13 for function, 15 for quality of life on 0-100 scales), the confidence intervals either did not reach those thresholds or spanned both important and unimportant improvement. Honest copy about exercise carries the same caveat honest copy about PRP does.
