Researchers conducted a systematic review of 10 trials of adults with meniscal tears: seven non-surgical, one pharmacological and two surgical. Findings were limited by small sample size.
What they found:
1. Patients receiving arthroscopic partial meniscectomy had a small mean improvement in knee pain (five studies, 943 patients).
2. Arthroscopic partial meniscectomy patients also had a small improvement in knee-specific quality of life (three trials, 350 patients) and knee function (six trials, 1,050 patients).
3. When restricted to people without osteoarthritis, patients receiving arthroscopic partial meniscectomy had a small to moderate improvement in knee pain (three trials, 402 patients), knee-specific quality of life (two trials, 244 patients) and knee function (four trials, 507 patients).
Researchers concluded, “Performing arthroscopic partial meniscectomy in all patients with knee pain and a meniscal tear is not appropriate, and surgical treatment should not be considered the first-line intervention. There may, however, be a small-to-moderate benefit from arthroscopic partial meniscectomy compared with physiotherapy for patients without osteoarthritis.”
