# When is it time to have my knee looked at? *When to Get a Knee Exam — Knee Pain Treatment Glendale* > Knee pain treatment Glendale starts with a routine exam; learn which warning signs need quick care and what happens during the visit. ## Is this worth an appointment? Glendale work near Loop 303 can keep you turning on hard floors. Your knee may get more sore with each shift. Arrange a routine exam if soreness keeps returning, limits walking, or wakes you. Swelling, catching, locking, or buckling also deserves a check. You don’t need to know the cause before you arrive. The examiner will ask about the ache, move the knee, and read earlier reports. I’d take every medicine name and the day the trouble started. Clear notes are more useful than a guess about the cause. ## Which warning signs can’t wait? After a major injury, get urgent care if putting weight on the leg is impossible, swelling comes fast, or the knee looks out of place. Don’t wait if that knee locks or your foot turns cold and pale. Fever with a knee that is hot, red, and swollen may mean an infection. Calf pain, warmth, and swelling can mean a clot, especially after travel or long periods without movement. New numbness, lost foot movement, or severe soreness after a joint procedure can’t wait. Neither can spreading redness, drainage, or fever afterward. These aren’t problems for a booked clinic visit. Get same-day advice or emergency help. ## What will happen at a routine visit? You’ll point to the sore spot and show which movements bring on the ache. The examiner will watch you stand, bend the knee, and walk. An X-ray may show wear, though the hands-on exam still matters. Strength, swelling, movement, sleep, and walking all help explain how much the knee limits you. Ask whether the person examining you is a doctor, nurse, or another trained clinician. The word provider alone doesn’t tell you that person’s role. Keep moving within a safe range while you wait, unless a warning sign appears. QC Kinetix has regenerative treatments, meaning clinic care that uses a sample collected from you; for its PRP, staff take arm blood, spin it to gather the platelet-rich portion, and put that portion into the knee after the exam, without promising a certain result. ## Sources 1. In a 2-year, double-blind RCT of 140 patients with symptomatic knee OA and ultrasound synovitis, intra-articular triamcinolone 40 mg every 12 weeks caused significantly GREATER cartilage volume loss than saline (index-compartment cartilage thickness change -0.21 mm vs -0.10 mm; between-group difference -0.11 mm, 95% CI -0.20 to -0.03) with NO significant difference in pain (-1.2 vs -1.9 on the WOMAC Likert pain subscale).

DOI: 10.1001/jama.2017.5283. 2. The RESTORE trial randomized 288 adults aged 50+ with symptomatic mild-to-moderate medial knee OA to three weekly leukocyte-poor PRP injections or saline placebo. At 12 months, pain change was -2.1 vs -1.8 points (difference -0.4; 95% CI -0.9 to 0.2; P=.17) and medial tibial cartilage volume change was -1.4% vs -1.2% (P=.81). 29 of 31 prespecified secondary outcomes showed no significant between-group difference. The authors concluded the findings 'do not support use of PRP for the management of knee OA.'

DOI: 10.1001/jama.2021.19415. 3. A randomized trial of 90 patients with KL grade 1-3 knee OA found bone marrow aspirate concentrate ('stem cell injection') was EQUIVALENT to, not better than, PRP at 24 months: no statistically significant IKDC or WOMAC difference between groups at any time point, with both improving from baseline and plateauing at 3 months.

DOI: 10.1177/03635465211072554. 4. A Radiology review documented four categories of adverse joint event structurally observed after intra-articular corticosteroid injection of the hip and knee: accelerated osteoarthritis progression, subchondral insufficiency fracture, complications of osteonecrosis, and rapid joint destruction including bone loss — concluding that these injections are 'perhaps not as safe as we thought' and that risk factors need to be identified before intervention. Kompel AJ, Roemer FW, Murakami AM, Diaz LE, Crema MD, Guermazi A. — [Intra-articular Corticosteroid Injections in the Hip and Knee: Perhaps Not as Safe as We Thought?](https://pubmed.ncbi.nlm.nih.gov/31617798/). *Radiology*, 2019. DOI: 10.1148/radiol.2019190341. 5. A safety review of intra-articular PRP in knee OA found significantly higher rates of mild knee pain and swelling than hyaluronic acid (p<0.001), driven specifically by leukocyte-RICH formulations; leukocyte-poor PRP showed a safety profile similar to HA. No severe adverse events were reported in any group.

FDA states verbatim: 'None of these products have been approved for the treatment of any orthopedic condition, such as osteoarthritis, tendonitis, disc disease, tennis elbow, back pain, hip pain, knee pain, neck pain, or shoulder pain.' The only FDA-approved stem cell products in the United States are blood-forming (hematopoietic progenitor) cells derived from umbilical cord blood, approved only for disorders of blood production. There are currently NO FDA-approved exosome products.
