# What are my choices for a sore joint? *Options Compared Honestly | Biologic Injections Tempe* > Biologic injections Tempe means joint care using blood or body tissue. Compare home care, medicines, platelet-rich plasma (PRP), and surgery. Your first steps may feel stiff and slow. The joint may ease after you move. It might ache again after chores or walking. You don't have to start with a procedure. Home care doesn't require one. Other choices need a doctor's exam. Your health and daily limits guide the choice. ## What can help before I choose a procedure? Easy motion can loosen stiffness. Strength work may support the joint. Losing weight may help if weight adds strain. You don't need to change everything at once. A doctor may suggest physical therapy. Your exercises won't stay the same during a flare. Tell the therapist how you feel the next morning. Stop an exercise when the pain turns sharp. Medicine doesn't suit everyone. Your health and other drugs decide what's safe. Don't borrow another person's pills. Ask your doctor or pharmacist first. ## Could blood or tissue treatments help? Biologic therapies are treatments that use blood or body tissue. Platelet-rich plasma, or PRP, uses your spun blood. Platelets are blood parts that help clotting. Research on PRP gives mixed results. One careful study assigned treatments by chance. It compared PRP with saline, or sterile salt water. PRP didn't give clearer relief than the salt water. Other knee studies have found later relief. Cortisone may ease soreness sooner. That relief can be brief. PRP may take longer when it helps. Neither choice replaces an exam of your joint. ## When does surgery deserve a serious look? Heavy joint wear can make each step hard. Sleep may suffer night after night. If basic care hasn't helped, surgery may make sense. A surgeon can explain its risks and likely result. You can still discuss knee or hip surgery alternatives. Regenerative treatments use blood or body tissue in joint care. No study has shown they rebuild worn joints. They can't fix every cause of soreness. Move the joint as safely as you can. Use a cane if one was fitted for you. Break up chores that cause swelling. QC Kinetix medical providers, meaning trained clinicians, can discuss non-surgical options after checking how your joint moves. ## Sources 1. The largest head-to-head trial of cell-based orthobiologics to date randomised 480 patients with KL II-IV knee OA across four arms: autologous bone marrow aspirate concentrate, autologous adipose stromal vascular fraction, allogeneic umbilical cord tissue-derived MSCs, and a corticosteroid injection control. At 12 months NONE of the three orthobiologic injections was superior to another or to the corticosteroid control on either co-primary endpoint (VAS pain, KOOS pain), and none of the four groups showed a significant change in MRI osteoarthritis score from baseline. No procedure-related serious adverse events were reported.

The 2025 Cochrane review of stem cell injections for knee osteoarthritis pooled 25 randomised trials (1,341 participants) and found that, compared with placebo injection, stem cell injection MAY slightly improve pain (1.2 points better on a 0-10 scale, 7 studies, 445 participants) and function (14.2 points better on a 0-100 scale, 7 studies, 432 participants) up to six months - both rated LOW-certainty evidence, downgraded for indirectness (cell source, preparation and dose varied across studies) and suspected publication bias, since up to three larger RCTs were conducted and withdrawn before reporting results. Radiographic progression was not assessed in any included study.

FDA states verbatim of stem cell products, stromal vascular fraction (adipose-derived cells), umbilical cord blood, Wharton's jelly, amniotic fluid and exosome products: '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, and there are currently NO FDA-approved exosome products.

A Bayesian network meta-analysis of 48 Level I-II randomized trials (9,338 knees) with a minimum 6-month follow-up ranked the four commonest intra-articular injections. HA and PRP both significantly improved pain versus placebo; HA, PRP and BMAC all significantly improved function versus placebo. SUCRA rankings were PRP 91.54, BMAC 76.46, HA 53.12, corticosteroid 15.18 and placebo 13.70 - corticosteroid ranked barely above placebo at six months and beyond.

A network meta-analysis restricted to LARGE randomized trials (at least 100 patients per group; 57 RCTs, 22,795 participants, 18 intra-articular interventions) found treatment effects were consistently larger in the 35 high-risk-of-bias trials than in the 22 low/unclear-risk trials. In the main analysis excluding high-risk trials, triamcinolone had the highest probability of exceeding the minimal important difference at weeks 2 and 6; hyaluronic acid had no effect on pain (SMD -0.04, 95% CrI -0.19 to 0.11, 11 trials) but higher odds of dropouts due to adverse events (OR 2.01) and of serious adverse events (OR 1.86). The effects of 16 of the 18 interventions were smaller than the MID and most were consistent with placebo effects.

RESTORE, the largest and most rigorously blinded placebo-controlled PRP trial in knee OA (n=288, participant-, injector- and assessor-blinded), gave three weekly injections of a commercial leukocyte-poor PRP or saline. At 12 months the change in knee pain was -2.1 vs -1.8 points (difference -0.4; 95% CI -0.9 to 0.2; P=.17) and the change in medial tibial cartilage volume was -1.4% vs -1.2% (difference -0.2%; P=.81). Twenty-nine of 31 prespecified secondary outcomes showed no between-group difference. The authors concluded the findings do not support the use of PRP for knee OA.

DOI: 10.1001/jama.2021.19415. 7. A meta-analysis of 10 RCTs of RECURRENT intra-articular corticosteroid injections (2-8 injections per patient) found they often gave inferior or non-superior relief compared with hyaluronic acid, PRP, saline or orgotein at 3 months and beyond, and no benefit over placebo in pain or function at 12-24 months.
