Role of Arthroscopic Surgery in Degenerative Knees with Mechanical Symptoms.

Background: This study was conducted to evaluate functional outcome in patients undergoing/underwent arthroscopic surgery for degenerative knees with mechanical symptoms or acute exacerbation of symptoms, not amenable to conservative measures.

Materials And Methods: This was a longitudinal type of study (prospective and retrospective). For the prospective cohort, followup was done at an interval of 2 weeks, 6 weeks, 6 months and 1 year to record visual analog scale (VAS), International Knee Documentation Committee (IKDC), and short form-8 (SF-8) scores. For the retrospective cohort, hospital records were studied to record the preoperative VAS score. Preoperative IKDC and SF-8 scores were recorded at final followup based on recall method (patient's memory). Furthermore, postoperative VAS, IKDC, and SF-8 scores at final followup were recorded.

Results: There were a total of 46 knees (28 retrospective and 18 prospective) in 44 patients. The mean age was 52.34 ± 11.73 years. There were 28 female knees and 18 male knees. The mean followup of patients in the retrospective cohort was 55 months (range: 13-126 months), whereas all patients in prospective cohort completed the minimum followup of 1 year. The improvements in VAS, IKDC, and SF-8 were statistically significant. Forty-one cases were successful and five cases were failure. All successful patients (41 cases) said "yes" and all failure cases (05) said "no" to the question-"If given a choice, would you still like to get the same surgery done for the same problem??". There was one complication deep venous thrombosis.

Conclusion: We recommend arthroscopic surgery in patients with degenerative knees, with mechanical symptoms and acute exacerbation of symptoms, not amenable to conservative measures.
