Could a Common Knee Surgery Accelerate Joint Deterioration Instead of Protecting It?
Could a knee surgery that many resort to for pain relief actually accelerate joint deterioration instead of protecting it? This is the question raised by a recent study, which revealed that certain common procedures used to treat meniscus tears may not yield the expected long-term benefits. In fact, they might even be linked to the worsening of knee osteoarthritis over time. So, what exactly did the researchers find?
A Common Knee Surgery May Not Deliver Expected Results
A recent study conducted by researchers from Finland and published in The New England Journal of Medicine revealed that a common knee surgery, known as “partial meniscectomy,” may not provide the expected benefits for patients with knee osteoarthritis. This procedure is used to remove the damaged part of the meniscus to relieve pain and improve knee mobility.
Long-term follow-ups showed that some patients who underwent this surgery experienced greater deterioration in joint osteoarthritis than expected. This raises questions about the effectiveness of this procedure as a routine treatment option for certain cases.
A 10-Year Follow-Up Reveals Concerning Surgical Outcomes
The study was based on a long-term follow-up spanning ten years post-surgery. Researchers compared patients who underwent partial meniscectomy with others who underwent sham (placebo) surgeries, during which no part of the meniscus was removed.
The results demonstrated that patients who underwent the actual surgery suffered a greater decline in knee function, along with a more pronounced progression of osteoarthritis symptoms compared to the control group. This casts doubt on the long-term benefit of this procedure for certain patients.
Why Might Knee Surgery Yield Counterproductive Results?
Researchers believe that the pain associated with knee osteoarthritis does not stem from the meniscus alone. Instead, it is linked to complex changes within the joint, including inflammation, wear and tear, and biological changes—issues that surgery does not directly address.
Furthermore, researchers point out that removing a portion of the meniscus can reduce the knee’s ability to absorb shock and distribute pressure within the joint. Over time, this can contribute to increased wear and accelerated progression of osteoarthritis.
