# When should a sore joint be checked? *When to Get Joint Soreness Checked | PRP Injections Mesa* > Know when joint soreness needs urgent care, when a regular visit makes sense, and what happens during PRP injections Mesa care. This page tells you which sore-joint signs can wait and which need quick care when your joint aches. Most lasting aches can be checked at a regular visit. Some warning signs call for faster help. ## When do I need care now? Seek urgent care when a joint is hot and badly swollen, especially if you also have fever. Sudden weakness, a joint that has changed shape, or trouble bearing weight after injury also needs prompt care. After treatment, get quick help for fever, drainage, or redness that spreads. For new calf swelling after a long period of stillness, call your doctor or urgent care right away, not the treatment clinic. ## When is a regular visit enough? A regular visit fits soreness that lingers, returns often, or limits normal movement during the day. Record the start of the ache and which motions make it better or worse during a normal day. Take any scan reports and a full list of your medicines. The doctor will check strength, movement, tender spots, and swelling before discussing whether more tests are needed at that visit. The visit also covers old injuries, swelling, sleep, and care you already tried. More tests may come up if the exam doesn’t explain the soreness. You will have time to ask what happens next. ## Could PRP, made by concentrating part of my blood, fit me? PRP may come up when home care and guided exercise haven’t eased the soreness enough. A doctor will weigh your exam, joint wear, and general health. Blood thinners, bleeding trouble, or an active illness need review before treatment. Results aren’t certain, and surgery can remain an option for severe joint wear. ## Sources 1. 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.

The American Academy of Physical Medicine and Rehabilitation convened a technical expert panel that ran a structured literature review (2023, updated through June 2025) and a modified Delphi process, and issued five evidence-based clinical recommendations plus 11 consensus-based best practices for PRP in knee osteoarthritis. The statement is explicit that orthobiologic therapies 'remain an evolving area of practice' and that robust, dose-dependent randomized controlled trials are still needed to establish PRP's clinical effects.

DOI: 10.1002/pmrj.70144. 3. A systematic review and meta-analysis of adverse events in randomized trials of intra-articular PRP for knee osteoarthritis found PRP associated with mild, transient adverse events - knee pain and swelling - that typically resolve without intervention, and more frequent with LEUKOCYTE-RICH formulations. Leukocyte-poor PRP had a safety profile similar to hyaluronic acid. Knee stiffness was more frequent with PRP than with normal saline (P=.031). No severe adverse events were reported in any group.

DOI: 10.1002/pmrj.70141. 4. A Bayesian network meta-analysis of nine studies (six RCTs, 1055 patients) found leukocyte-POOR PRP produced significantly better WOMAC scores than hyaluronic acid (mean difference -21.14; 95% CI -39.63 to -2.65) and than placebo (-17.84; 95% CI -34.95 to -0.73), while leukocyte-RICH PRP showed no such significant difference versus placebo. PRP of either type caused more local adverse reactions than hyaluronic acid (OR 5.63; 95% CI 1.38-22.90), almost always local swelling and pain, with no difference in safety between the two PRP types.

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.
