Management of Meniscal Tears: Surgery May Not Be Necessary

Lara C. Pullen, PhD  |  November 18, 2019

For those patients who did not cross over and remained in the physical therapy arm, the change in pain score became similar to those who received surgical intervention between three and 12 months. By 12 months, scores in all three of the as-treated groups were similar.

Some of the patients—9.2% of those randomized to arthroscopic partial meniscectomy and 5.1% of those randomized to physical therapy—underwent total knee replacement over the course of follow up. The participants who ultimately underwent total knee replacement started with the highest KOOS Pain scores and experienced the slowest improvement in pain over the first three months of the study. Although the investigators were unable to identify the cause of this difference, they did document a five-fold increased risk of total knee replacement among those exposed to arthroscopic partial meniscectomy as compared with those treated non-operatively.

“Rheumatologists should be reassured by our findings that pain and function improved considerably for both strategies, with these improvements maintained over five years of follow up. Both strategies—early treatment with arthroscopic partial meniscectomy and physical therapy with the opportunity for delayed arthroscopic partial meniscectomy—are associated with generally favorable outcomes in middle-aged and older persons presenting with knee pain, osteoarthritic changes and degenerative meniscal tear,” says Dr. Collins. “A note of caution is that those subjects undergoing surgery had a slightly increased risk of undergoing total knee replacement.”

He suggests patients and clinicians discuss this risk when contemplating treatment for knee pain, meniscal tear and osteoarthritic changes.

    When a young patient arrives at a clinic complaining of knee pain with clicking or popping, a meniscal tear is often the culprit. “In young [people], there’s a pretty classic presentation of meniscal tear, with clicking and other mechanical symptoms, because the tear rubs up against different tissues,” says Jeffrey Katz, MD, MSc, a rheumatologist…
