Our Summary

This study looked at how well people under 60 years old who had total knee replacements were able to return to sports. The researchers looked back at 41 knee replacements in 36 people who were active in sports (average age 53 years old) over an average of two years. Most of the patients had osteoarthritis, a few had complications from rheumatoid arthritis, and one had a deformity outside the joint. The researchers used two tests to measure how well the knee was functioning and how active the patients were after surgery. The results showed that, on average, patients improved their scores on these tests significantly after their surgeries. Most patients were able to return to sports around 3 and a half months post-surgery, but three patients did not return to sports. The researchers concluded that delaying surgery in these patients could lead to worsening of their arthritis and an end to their sports activities. This could also make surgery more difficult and reduce the patient’s physical performance. The study also found that more than 80% of the knee implants were still doing well after 25 years in younger patients.

FAQs

  1. What was the average age of the patients who had knee replacements in this study?
  2. How long did it typically take for patients to return to sports activities after knee replacement surgery?
  3. What was the longevity of knee implants in younger patients according to the study?

Doctor’s Tip

One important tip a doctor might give a patient considering knee replacement surgery is to not delay the procedure if their arthritis is worsening and limiting their ability to participate in sports or other physical activities. Delaying surgery could lead to further deterioration of the joint and make the procedure more difficult in the future. Additionally, the study mentioned shows that the majority of knee implants in younger patients are still functioning well after 25 years, indicating that the benefits of surgery can be long-lasting.

Suitable For

Patients who are typically recommended for knee replacement surgery are those who have severe knee pain, stiffness, and limited mobility that significantly impacts their daily activities and quality of life. These patients may have conditions such as osteoarthritis, rheumatoid arthritis, or other degenerative joint diseases. Younger patients who are active in sports or have a high level of physical activity may also be candidates for knee replacement surgery if conservative treatments have not been effective in managing their symptoms. The study mentioned above suggests that knee replacement surgery can be successful in younger, active patients and can help them return to their sports activities and maintain their physical performance.

Timeline

  • Before knee replacement:
  1. Patient experiences chronic knee pain, stiffness, and swelling.
  2. Patient may have difficulty walking, climbing stairs, and performing daily activities.
  3. Patient may have tried non-surgical treatments such as physical therapy, medications, and injections without success.
  4. Patient consults with an orthopedic surgeon who recommends knee replacement surgery.
  5. Patient undergoes pre-operative assessments and preparation for surgery.
  • After knee replacement:
  1. Patient undergoes knee replacement surgery, which typically takes 1-2 hours.
  2. Patient stays in the hospital for a few days for recovery and rehabilitation.
  3. Patient starts physical therapy to regain strength and mobility in the knee.
  4. Patient may experience post-operative pain and swelling, which gradually improves over time.
  5. Patient gradually increases activity level and returns to daily activities.
  6. Patient follows up with the surgeon for post-operative appointments and monitoring of the knee implant.
  7. Patient may be able to return to sports and other high-impact activities around 3-6 months post-surgery, depending on individual recovery and rehabilitation progress.
  8. Long-term follow-up shows that the majority of knee implants in younger patients continue to function well for over 25 years.
