Arthroscopic partial meniscectomy. Technique and long-term results

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Knee Arthroscopy

Background:

• Meniscal tears are common knee injuries.
• Arthroscopic meniscectomy is a frequent surgical treatment.
• Assessing long-term functional outcomes is crucial.

Purpose of the Study:

• To evaluate the functional results of arthroscopic meniscectomy.
• To identify factors influencing outcomes.
• To compare results in isolated meniscal tears versus those with concurrent conditions.

Main Methods:

• Retrospective review of 125 patients undergoing arthroscopic meniscectomy.
• Follow-up questionnaire study with a knee function rating system for 110 patients.
• Analysis of outcomes based on meniscal lesion type, osteoarthritis, chondromalacia, and knee instability.

Main Results:

• Best functional results were observed in isolated meniscal lesions.
• Osteoarthritis and chondromalacia negatively impacted outcomes, though some patients reported subjective improvement.
• Knee instability, particularly cruciate insufficiency, was associated with poor outcomes, with 28% requiring further surgery.

Conclusions:

• Arthroscopic meniscectomy yields optimal results for isolated meniscal tears.
• Subjective improvement may occur in degenerative joint disease, but outcomes are less predictable.
• Endoscopic meniscectomy is not the primary choice for unstable knees unless contraindications exist for stabilizing surgery.
