Background: A variety of procedures have been described for treatment of the osteoarthritic knee. Comprehensive Arthroscopic treatment regime has definite role in treating patients with knee Osteoarthritis.
Aim: To evaluate the role of arthroscopy in functional and subjective outcomes of patient with moderate to severe osteoarthritis of knee.
Materials and Methods: Between October 2011 to September 2013, 30 patients were treated with an arthroscopic regimen. Patients with primary osteoarthritis who fulfilled clinical and radiographic classification criteria of American College of Rheumatology for osteoarthritis were included. All patients were followed for 18 months. All patients were subjected to comprehensive arthroscopic treatment.
Results: Overall, mean age was 59 years, with 17 females and 13 males. According to Kellgren Lawrence scale, 17 patients had grade 2 osteoarthritis, 10 had grade 3 osteoarthritis and 3 patients had grade 4. The average preoperative Lysholm score was 38.8. According to Outerbridge grading of chondral surface lesions, 14 patients were in grade-1, 5 in grade-2, 8 in grade-3 and 3 patients were in grade-4. The average 18 months postoperative Lysholm score was 83.3 (range 60- 96). 73.33% patients showed good/ excellent outcome. 80% of patients with chondral and meniscal lesions showed excellent/good outcome.
Conclusion: This arthroscopic treatment regimen can improve function and activity levels in patients with moderate to severe osteoarthritis. Patients with meniscal and chondral pathology will be benefited more by arthroscopic treatment.
