People with meniscus tears who underwent surgery had poorer knee function and worse osteoarthritis after 10 years than those who did not

A common knee surgery for cartilage damage does not benefit patients and may lead to worse outcomes, a 10-year trial suggests.

The study tracked outcomes for patients treated for a meniscus tear, who were given a partial meniscectomy, one of the most common orthopaedic surgeries. Their trajectories were compared with patients who had randomly been assigned to receive “sham surgery”, in which no procedure was carried out.
