Partial or total open meniscectomy? : A prospective, randomized study

Area of Science:

• Orthopedic Surgery
• Knee Arthroscopy
• Meniscal Repair

Background:

• Meniscal tears are common knee injuries requiring surgical intervention.
• Partial and total meniscectomy are surgical options with varying outcomes.
• Evidence comparing long-term efficacy of partial versus total meniscectomy is limited.

Purpose of the Study:

• To prospectively compare the clinical outcomes of partial meniscectomy versus total meniscectomy.
• To evaluate symptom relief, need for reoperation, and radiological changes between the two surgical techniques.

Main Methods:

• Prospective clinical study involving 200 patients undergoing arthrotomy for meniscal tears.
• Patients were randomized into two groups: 100 for partial meniscectomy and 100 for total meniscectomy.
• Follow-up assessments were conducted at 2 and 12 months post-operation.

Main Results:

• No significant differences were observed in symptom duration, age, sex distribution, or time off work between groups.
• One year post-surgery, partial meniscectomy resulted in significantly greater symptom relief compared to total meniscectomy.
• Radiological changes were comparable between the partial and total meniscectomy groups one year after surgery.

Conclusions:

• Partial meniscectomy offers superior symptom relief one year after surgery compared to total meniscectomy.
• Both surgical approaches demonstrated similar radiological progression and did not significantly differ in initial recovery time.
• Further investigation into reoperation rates, particularly for posterior tears in partial meniscectomy, is warranted.
