Many people with knee osteoarthritis (knee joint degeneration) have meniscal damage. (The menisci of the knee act as shock absorbers and stabilisers in the knee joint). Commonly, this meniscal damage is treated with surgical removal of the damaged area (partial mensicectomy).

This study, which was published in 2013, aimed to assess whether adding meniscal surgery to physiotherapy in older people with a meniscal tear and mild to moderate knee osteoarthritis had greater improvement in pain and function than treatment with physiotherapy alone.

Patients in the study were divided into two groups: 1) arthroscopic partial meniscectomy followed by physiotherapy or 2) physiotherapy alone. The physiotherapy programs were the same and included hands-on treatment and exercise.
Patients in the study were followed up 3, 6, and 12 months after the start of the study using the WOMAC questionnaire (a questionnaire specific to people with OA). It was found that there was no difference in retest scores between the surgical and physiotherapy alone groups at both 6 and 12 months follow up. Some patients in the surgical group had achieved a positive outcome at 6 months.

So what does this all mean? Well, it seems there is clear evidence of little benefit of arthroscopic surgery for meniscal tears over a physiotherapy program for older adults with knee osteoarthritis. The results also suggest that patients trial a 2-3 month physiotherapy program and only those without significant improvement in that period be considered for meniscectomy.

There is good evidence that starting treatment with physiotherapy is likely to be just as beneficial as rushing to go under the knife as means of treating degenerative meniscal tears in older adults.
