Knee surgery 'does not reduce arthritis risk'

Surgical interventions to repair torn ligaments or cartilage in the knee does not reduce the risk of developing osteoarthritis, it has been suggested.

A new study published in the medical journal Radiology showed that knee osteoarthritis was evident in patients who had suffered torn anterior cruciate ligaments or meniscal cartilage injuries ten years previously.

The report revealed that osteoarthritis, which is a wear and tear form of arthritis, was apparent in patients regardless of whether they underwent a surgical procedure.

Dr Kasper Huetin of Leiden University Medical Centre in the Netherlands was the lead researcher for the new study.

He said: "This study proves that meniscal and cruciate ligament lesions increase the risk of developing specific types of knee osteoarthritis. Surgical therapy does not decrease that risk."

"There is a higher risk of developing knee osteoarthritis at specific sites after tearing a meniscus or cruciate ligament. We showed a direct relationship between injury and long-term consequences, and showed that surgery has no impact on long-term outcomes," the scientist added.
