Debridement arthroscopy. 10-year followup.

Area of Science:

• Orthopedics
• Sports Medicine
• Regenerative Medicine

Background:

• Osteoarthritis of the knee presents significant treatment challenges.
• Arthroscopic debridement is proposed as an effective, less invasive option for knee osteoarthritis.
• Patients often consider total knee replacement as a definitive solution.

Purpose of the Study:

• To evaluate the long-term efficacy of arthroscopic knee debridement in patients with knee osteoarthritis.
• To assess pain relief, functional restoration, and the rate of subsequent total knee arthroplasty (TKA).
• To determine patient satisfaction and activity levels after arthroscopic debridement.

Main Methods:

• A subjective telephone interview was conducted with patients who underwent arthroscopic debridement.
• Follow-up was performed at an average of 13.2 years post-procedure.
• Data collected included rates of TKA, patient satisfaction, and Tegner activity scores.

Main Results:

• 67% of 91 knees did not require total knee arthroplasty at an average follow-up of 13.2 years.
• Patient satisfaction averaged 8.6/10, with a Tegner activity score of 3.5.
• 33% of patients underwent TKA, with 7 of these within 2 years, often associated with Outerbridge Grade 4 changes and meniscus tears.

Conclusions:

• Arthroscopic knee debridement can provide significant long-term functional benefits and pain relief for knee osteoarthritis patients.
• A notable percentage of patients, even those with severe cartilage damage, avoided total knee replacement for over a decade.
• Arthroscopic debridement serves as a valuable temporizing procedure, potentially delaying or preventing the need for total knee arthroplasty.
