PRP Queen Creek: what can help your sore joint?

Why does my joint keep getting sore?

Notice when the ache shows up. Extra walking, lifting or reaching can upset a joint or the strong cord called a tendon.

Wear from arthritis can also bring an ache, stiffness or swelling. A past injury may flare after work that once felt easy.

Sharp pain means stop. Easy motion is fine, but stop if the joint feels weak or gives way.

What will happen at QC Kinetix?

First comes an exam. A medical provider is the office's name for the trained person in charge of your exam and care.

Ask when booking whether you'll see a doctor, nurse or another care team member. That person checks the sore spot, your movement and the care you've already tried.

The clinic uses regenerative treatments to mean non-surgery care that can include PRP prepared there from your blood. Your blood is spun, the layer with more platelets is kept, and that part is returned by a shot.

Here's the catch. The findings may rule out PRP, and no result is certain.

When does my joint need an exam?

Get it checked when the ache keeps returning, wakes you or stops normal tasks. An exam can find the likely cause and show whether an X-ray may help.

Don't wait if you have fever and a joint that's hot and swollen. Get care now after a hard injury if your leg won't hold you or new weakness starts.

Routine visits are in Chandler near Dobson Road and the Santan Freeway. Call first, so you won't make the drive without the records they need.

1. 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.

2. A Bayesian network meta-analysis restricted to LARGE randomized trials (at least 100 patients per group; 57 trials, 22,795 participants, 18 intra-articular interventions) found treatment effects were larger in the 35 high-risk-of-bias trials than in the 22 low/unclear-risk trials. Excluding high-risk trials, the effects of 16 of the 18 intra-articular interventions in knee or hip OA were smaller than the minimal clinically important difference and most were consistent with placebo effects; triamcinolone had the highest probability of exceeding the MID at weeks 2-6.

3. A meta-analysis of 73 articles covering 5,895 patients quantified the PLACEBO response to intra-articular injection in knee osteoarthritis: statistically and clinically significant improvements in pain, function and quality of life at 1, 3 and 6 months, with responder rates above 50% at each of those points, declining by 12 months. The placebo response was stronger in trials with more female participants and in more recently published trials. This is why an uncontrolled 'our patients improved' figure carries almost no information.

4. A systematic review of 105 clinical PRP studies in orthopaedics published 2006-2016 found that only 11 (10%) described the preparation protocol clearly enough for another investigator to repeat it, and only 17 (16%) reported any quantitative metric of the final PRP composition. The authors concluded that the current reporting of PRP preparation and composition does not allow the PRP products actually delivered to patients to be compared between studies.
