Common Knee Surgery May Harm Patients
1 May
Summary
- Partial meniscectomy offers no long-term benefit for knee pain.
- Surgery linked to increased knee arthritis progression.
- Procedure may be ineffective or even harmful, study suggests.
A frequently performed knee surgery, known as partial meniscectomy, for torn meniscus cartilage does not provide long-term benefits and may even be detrimental, a recent study indicates. Published on April 29, 2026, in The New England Journal of Medicine, the research followed nearly 150 individuals in Finland for ten years.
Patients who underwent the surgery showed no significant improvement in knee pain or function compared to those who received a sham procedure. However, the surgical group experienced a notably higher rate of significant knee arthritis progression, with approximately 81% showing worsening arthritis compared to 70% in the sham group.
Researchers suggest that the underlying assumption that medial meniscus tears directly cause pain treatable by surgery may be flawed. They propose that knee joint pain is often related to age-related degeneration. Despite recommendations from various health organizations to discontinue the procedure, some professional bodies continue to endorse it, highlighting the difficulty in abandoning ineffective therapies.
