Our Summary

This study investigated the long-term effects of a particular type of knee surgery, arthroscopic partial meniscectomy (APM), on the risk of developing knee osteoarthritis, a common condition that causes joint pain and stiffness. The trial included 146 adults with knee problems, who were randomly assigned to receive either APM or a placebo surgery. The results showed that patients who had APM were slightly more likely to develop knee osteoarthritis as seen on X-rays, compared to those who had the placebo surgery. However, there was no notable difference between the two groups in terms of knee symptoms and functionality. In simple terms, APM seems to increase the risk of knee osteoarthritis but does not appear to provide significant benefits in terms of patients’ symptoms or ability to use their knee. This was observed five years after the surgery took place.

Doctor’s Tip

One helpful tip a doctor might tell a patient about meniscectomy is to follow a structured rehabilitation program to strengthen the muscles around the knee and improve range of motion. This can help prevent further knee issues and improve overall knee function. Additionally, maintaining a healthy weight and staying active can also help support the healing process and prevent future complications. It’s important to follow your doctor’s advice and attend follow-up appointments to monitor your progress and address any concerns.

Suitable For

Patients who are typically recommended for a meniscectomy are those who have a torn meniscus in the knee that is causing symptoms such as pain, swelling, and limited range of motion. Meniscus tears can occur due to sudden trauma or degenerative changes in the knee joint. Meniscectomy is often recommended when conservative treatments such as physical therapy and medication have not provided relief, and the patient’s symptoms significantly impact their daily activities. It is important for patients to discuss the risks and benefits of meniscectomy with their healthcare provider to determine if it is the most appropriate treatment option for their specific condition.

Timeline

Before meniscectomy:

  • Patient experiences knee pain, swelling, and limited range of motion
  • Patient undergoes physical examination, imaging tests (such as MRI), and possibly conservative treatments like physical therapy or medication
  • Decision is made to undergo meniscectomy surgery

After meniscectomy:

  • Patient undergoes pre-operative preparation, including medical evaluations and discussions with the surgeon
  • Meniscectomy surgery is performed, removing part or all of the damaged meniscus
  • Patient undergoes post-operative care, including pain management, physical therapy, and follow-up appointments
  • Patient may experience temporary increase in pain and swelling, followed by gradual improvement in symptoms
  • Patient gradually resumes normal activities and physical therapy to strengthen the knee
  • Long-term effects of meniscectomy, such as risk of developing knee osteoarthritis, are monitored through follow-up appointments and imaging tests.
