Knee pain is a common complaint among older adults. Up to 25% of persons 55 years and older consult a doctor for it. Torn meniscus and osteoarthritis are frequently seen with a painful knee. Surgical repair of meniscus tears has often been recommended and currently up to 4 million arthroscopic menisectomy procedures are performed each year.
However, controversy around this surgery for older adults has brewed for years.[i] It has been observed that arthritis and meniscal tears are seen in up to 30% of adult knees regardless of whether or not the person has knee pain. A recent systematic review and meta-analysis published in the British Journal of Sports Medicine on February 22, 2019 further questions the wisdom of the surgery in adults with a torn meniscus and osteoarthritis.[ii]
The authors of this review compared the outcomes of non-surgical intervention, drugs, surgery and no treatment. The research showed no difference between surgical menisectomy and a placebo, sham surgery. The conclusion was that while more research is needed, performing surgery “in all patients with knee pain and a meniscal tear is not appropriate, and surgical treatment should not be considered the first-line intervention.”
In contrast, the evidence supporting typical IH interventions for knee pain is emerging. A 2016 meta-analysis concluded that acupuncture provided short term pain relief and, more importantly, improved short and long-term physical function. Preliminary evidence from case reports suggest that manipulative treatment can also be effective for improving knee pain and function.[iii],[iv]
Clearly, a trial of conservative care such as that offered by IH providers is a reasonable, safe and potentially effective first-line treatment.
