When should knee surgery enter the talk?

What is still worth trying first?

Regular, gentle movement can ease stiffness and keep the leg useful. Stronger thigh muscles may take some strain off the knee. Heat, cold, medicine, a cane, or a brace may also help. Comfort and easier daily tasks are the useful tests.

Choose one task that the care is meant to improve. It might be stairs, a short walk, or rising from a chair. Set a date to discuss the result with your doctor. If the task stays hard, repeating the same advice isn't enough.

Could a non-surgical visit still help?

A visit may still help, but the exam has to come first. After checking soreness caused by a condition, QC Kinetix may offer regenerative treatments, including care made on site from a sample of your blood. Its medical providers are the people there who check the knee and discuss non-surgical choices. They can also explain surgery alternatives without promising that one will fit.

Marketing may make blood-based care sound like a sure escape from surgery. The largest careful test found no more relief than a salt-water shot. Other reviews found better movement than with gel shots, so the findings conflict. Ask how likely relief is, how long it may last, and what care comes next.

When does replacement deserve a serious talk?

Replacement deserves a serious talk when soreness still rules the day. That talk matters more after sound non-surgical care hasn't restored useful movement. An x-ray can show joint damage, while the exam shows how the knee moves. Your trouble with sleep, stairs, and walking belongs in the decision too.

Surgery may bring more relief, but it also brings risk and recovery work. Waiting isn't harmless when walking, sleep, and strength keep getting worse. Ask your surgeon what waiting might cost and when to review the choice. A firm review date is clearer than endless delay.

Don't debate timing when urgent signs appear. A hot, red, swollen knee with fever needs prompt care. A major injury or sudden inability to stand also needs medical help.

Evidence sources

1. The 2023 ACR/AAHKS timing guideline conditionally recommends AGAINST delaying hip or knee arthroplasty to pursue additional non-operative treatment - physical therapy, NSAIDs, ambulatory aids or intra-articular injections - in patients with moderate-to-severe osteoarthritis for whom non-operative therapy has already been ineffective and who have chosen surgery. It conditionally recommends delay for nicotine cessation and for better glycemic control in diabetes, states that obesity by itself is not a reason for delay while weight loss should be strongly encouraged, and conditionally recommends against delay in patients with severe deformity or bone loss. Evidence for all recommendations was graded low or very low quality.

Arthritis & Rheumatology, 2023.

2. Pooling the OAI and MOST cohorts (8,002 participants followed up to 8 years, 3,417 classifiable knees), validated appropriateness criteria classified only 290 knees (8%) as receiving a TIMELY total knee replacement, 2,833 knees (83%) as potentially appropriate but not replaced more than 2 years after replacement became appropriate, and 294 knees (9% of all knees, 26% of the 1,114 replacements actually performed) as PREMATURE. Of the potentially-appropriate-but-not-replaced knees, 1,204 (42.5%) had severe symptoms.

3. Applying a modified validated appropriateness classification to 205 Osteoarthritis Initiative patients who underwent total knee arthroplasty in the US, 44.0% (95% CI 37-51%) of the procedures were classified appropriate, 21.7% (95% CI 16-28%) inconclusive and 34.3% (95% CI 27-41%) inappropriate - approximately one third judged inappropriate, against about 20% in earlier studies outside the US.

4. In 63,158 hip and 54,276 knee replacement patients in the Clinical Practice Research Datalink, the lifetime risk of requiring revision surgery was about 5% for patients operated on after age 70 with no sex difference, but rose to 35% (95% CI 30.9-39.1) for men having surgery in their early 50s, with women's risk about 15% lower at the same age. Median time to revision for patients operated on younger than 60 was 4.4 years. The authors state their evidence challenges the trend toward more replacements in younger patients.

5. A systematic review and meta-analysis of 89,996 patients (60.6% female, mean age 67.4) awaiting primary elective total hip or knee replacement found a significant deterioration in joint function (mean difference 0.0575% per additional day of waiting, 95% CI 0.0064 to 0.1086, p=0.028) and in health-related quality of life per additional day of waiting. Meta-analysis could not detect a relationship with post-operative outcomes, and patient responses to delayed surgery were unanimously negative.

6. In a prospective cohort of 134 patients on an Australian public orthopedic waiting list for hip or knee replacement, 69% waited at least 6 months (median 286 days, IQR 169-375). Health-related quality of life deteriorated overall during the wait (mean AQoL change -0.04, 95% CI -0.08 to -0.01), with 53% of participants experiencing a clinically important decline.

7. In the only randomised controlled trial to compare total knee replacement directly with non-surgical treatment in patients already eligible for surgery (n=100), the replacement group improved more at 12 months than the non-surgical group (KOOS4 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). Only 13 of 50 patients (26%) assigned to non-surgical treatment alone had undergone knee replacement by 12 months.

8. At 2 years across two parallel randomised trials (200 patients, mean age 66), total knee replacement plus non-surgical treatment beat non-surgical treatment alone by 18.3 KOOS points (95% CI 11.3 to 25.3), and non-surgical treatment in turn beat written advice by 7.0 points (95% CI 0.4 to 13.5). Among patients eligible for replacement, 16 of 50 (32%) in the non-surgical group had surgery within 2 years - meaning two out of three delayed it for at least two years.

9. OARSI 2019 designates arthritis education plus structured land-based exercise (with or without dietary weight management) as CORE treatments for knee OA, and education plus structured land-based exercise as core for hip and polyarticular OA. Topical NSAIDs are strongly recommended for knee OA (Level 1A). Intra-articular corticosteroids and hyaluronic acid are Level 1B/2 for knee OA depending on comorbidity and are NOT recommended for hip or polyarticular OA. Oral NSAIDs are not recommended for people with cardiovascular comorbidity or frailty, and oral and transdermal opioids are strongly not recommended (Level 5).

10. The 2019 ACR/Arthritis Foundation guideline makes STRONG recommendations for exercise, weight loss in people with knee and/or hip OA who are overweight or obese, self-efficacy and self-management programs, tai chi, cane use, tibiofemoral bracing for tibiofemoral knee OA, topical NSAIDs for knee OA, oral NSAIDs, and intra-articular glucocorticoid injections for knee OA. Radiofrequency ablation for knee OA, acupuncture, thermal modalities, acetaminophen, duloxetine and tramadol are only CONDITIONAL recommendations.

11. In 100 adults with mostly moderate-to-severe knee OA who were judged NOT eligible for knee replacement, a 12-week individualised non-surgical programme (neuromuscular exercise, education, insoles, dietary advice, pain medication if indicated) beat usual care at 12 months by 9.6 KOOS4 points (95% CI 4.4 to 14.8), with a number needed to treat of 7.2 for a 15% improvement and no serious treatment-related adverse events.

12. Pooled national registry data covering 299,291 total knee replacements across 14 registries give a 25-year all-cause survival of 82.3% (95% CI 81.3-83.2); pooled 25-year survival of unicompartmental knee replacements across four registries was 69.8% (67.6-72.1).

13. In 156 patients with knee osteoarthritis randomised in the US Military Health System, physical therapy produced a mean WOMAC total score of 37.0 at one year versus 55.8 for a single intra-articular glucocorticoid injection (mean between-group difference 18.8 points favouring physical therapy, 95% CI 5.0 to 32.6, on a 0-240 scale where higher is worse). Secondary outcomes moved in the same direction.

14. Acute bacterial septic arthritis of the knee is an orthopaedic emergency that can cause substantial joint destruction if untreated. Diagnosis rests primarily on history and the clinical presentation of a red, warm, swollen, painful joint with limited range of motion. Risk factors include age over 60, recent bacteremia, diabetes, cancer, cirrhosis, renal disease, drug or alcohol abuse, a HISTORY OF CORTICOSTEROID INJECTION, recent injury or surgery, a prosthetic joint, and rheumatoid arthritis.
