Which treatment may help my sore joint?

What can help without a procedure?

Regular movement can keep the joint from becoming more stiff. Physical therapy teaches exercises for strength, balance, and safer motion. The work needs to grow slowly enough for you to keep doing it.

A brace or cane may reduce strain around the sore area. Heat can loosen the joint, while cold may settle swelling afterward. Topical medicine means a cream or gel rubbed on the sore joint; ask whether it is safe for you.

What are the treatments made from my own blood?

Biologic therapies are clinic treatments made with blood or other material from your own body. PRP means platelet-rich plasma; plasma is your blood's liquid part, prepared with platelets for a joint shot. Platelets are small blood parts that take part in the body's repair response.

Concentrated PRP is made with more platelets than regular PRP. More platelets describes the mixture; it doesn't promise a better result. These are called regenerative treatments, meaning non-surgical care made from your own material.

What are my alternatives to knee replacement?

Surgery alternatives may include exercise, a brace, medicine, and clinic treatments. Changing activity can mean shorter walks, fewer stairs, or carrying less weight. Natural pain treatments here mean gentle movement, heat, cold, and better support for the joint.

An operation may make sense when damage is severe and daily tasks keep shrinking. Hearing about surgery doesn't mean you have agreed to it. Ask what each choice may change about your walking, sleep, or use of the joint.

The 2019 ACR/Arthritis Foundation guideline makes STRONG recommendations for exercise, weight loss in people with overweight or obesity, self-efficacy and self-management programmes, tai chi, cane use, hand orthoses for first-CMC joint OA, tibiofemoral bracing, topical NSAIDs for the knee, oral NSAIDs and intra-articular glucocorticoid injections for the knee; acupuncture, thermal modalities, radiofrequency ablation, acetaminophen, duloxetine and tramadol are only conditional.

2. OARSI designates arthritis education plus structured land-based exercise (with dietary weight management for the knee) as CORE treatments for knee, hip and polyarticular OA. Topical NSAIDs are Level 1A for knee OA. Intra-articular corticosteroids, intra-articular hyaluronic acid and aquatic exercise are Level 1B/2 for the KNEE only and are NOT recommended for hip or polyarticular OA. Acetaminophen is conditionally not recommended, and no oral NSAID is recommended for people with cardiovascular comorbidity or frailty.

3. The Cochrane review of land-based therapeutic exercise for knee osteoarthritis extracted data from 54 studies, with high-quality evidence from 44 trials (3,537 participants) that exercise reduces pain immediately after treatment, and further high-quality evidence that it improves physical function. Benefit attenuates but persists for at least two to six months after the programme ends.

4. In a randomized trial of 156 US Military Health System primary-care patients with knee osteoarthritis, physical therapy beat glucocorticoid injection at one year: mean WOMAC total scores were 37.0 with physical therapy versus 55.8 with injection (mean between-group difference 18.8 points, 95% CI 5.0 to 32.6, lower is better), with secondary outcomes in the same direction.

5. In a two-year double-blind randomized trial of 140 patients with symptomatic knee OA and ultrasonic synovitis, intra-articular triamcinolone 40 mg every 12 weeks produced 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.

6. A BMJ systematic review and meta-analysis of 169 trials (21,163 participants) found that in the pre-specified main analysis of 24 large placebo-controlled trials (8,997 participants), viscosupplementation reduced pain by only SMD -0.08 (95% CI -0.15 to -0.02) - about 2.0 mm on a 100 mm scale - with the confidence interval excluding the minimal clinically important difference of -0.37. Trial sequential analysis indicated conclusive evidence of clinical equivalence to placebo since 2009.

7. The RESTORE randomized clinical trial (n=288) compared three weekly intra-articular injections of leukocyte-poor PRP with saline placebo in symptomatic mild-to-moderate medial knee OA. At 12 months the mean change in knee pain was -2.1 versus -1.8 points (difference -0.4, 95% CI -0.9 to 0.2, P=.17) and the mean change in medial tibial cartilage volume was -1.4% versus -1.2% (P=.81). Twenty-nine of 31 prespecified secondary outcomes showed no significant between-group difference.

FDA states verbatim that stem cell products, stromal vascular fraction (adipose-derived), umbilical cord blood, Wharton's jelly, amniotic fluid and exosome products have NOT 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.

9. In the only randomized trial of total knee replacement (100 patients with moderate-to-severe knee OA), the surgery group improved more on the KOOS4 score at 12 months than the non-surgical group (32.5 vs 16.0; adjusted mean difference 15.8, 95% CI 10.0 to 21.5) - but had four times the serious adverse events (24 vs 6, P=0.005), and 26% of the non-surgical group chose surgery within the year while 74% did not.
