Should you have this knee checked?

Which signs need prompt medical care?

Fever or chills with a red, burning, swollen knee need help now. An infection is possible, so don't wait for a regular visit.

A hard injury needs quick care when you can't put weight on the leg. A bent-looking knee, cold foot, or new numbness also needs attention.

Warmth and swelling in your calf may mean a blood clot. Fever, night sweats, or weight loss with soreness also need a doctor.

When is a regular visit worthwhile?

A regular visit is worthwhile when soreness limits sleep or walking. It's also useful when normal activity keeps bringing swelling.

You may have tried rest, a brace, medicine, or exercise. Tell the person examining you so the visit doesn't repeat failed care.

QC Kinetix provides regenerative treatment options for some soreness due to arthritis: knee shots made from your blood or bone marrow, the soft tissue inside bones. The exam helps the clinic decide whether those non-surgical choices may fit.

What happens while your knee is checked?

The medical provider will ask how your ache started and where it hurts. Then you'll get a hands-on check of motion, strength, and swelling.

The exam may lead to an X-ray showing wear between the bones. An X-ray isn't always needed and can't replace the exam.

A useful visit ends with clear choices and plain limits. You'll want to know what may fit, what won't, and the cost.

The 2019 ACR/Arthritis Foundation guideline makes STRONG recommendations for exercise, weight loss in people with overweight or obesity, self-efficacy and self-management programs, tai chi, cane use, tibiofemoral bracing, topical NSAIDs, oral NSAIDs and intra-articular glucocorticoid injections in knee OA; radiofrequency ablation for knee OA is only a conditional recommendation.

In a randomized trial of 100 patients with moderate-to-severe knee OA eligible for total knee replacement, TKR followed by 12 weeks of non-surgical care improved the KOOS4 score more than the same non-surgical programme alone (32.5 vs 16.0 points; adjusted mean difference 15.8, 95% CI 10.0 to 21.5) — but produced four times as many serious adverse events (24 vs 6, P=0.005), and 26% of the non-surgical group had chosen surgery within 12 months, meaning roughly three-quarters had not.

A prospective longitudinal study of 64 patients with acute medial meniscus posterior root tear managed non-operatively found 76.6% continued non-operative care and only 23.4% converted to surgery (median 6 months). Pain fell from 7.6 to 1.3 on an 11-point scale within 6 months and stayed there — even though structural degeneration on MRI progressed. Symptoms and structure moved in opposite directions.
