Prospective, Randomized, Double Blinded Trial Comparing Clinical, Radiological and Laboratory Outcomes of Hight Tibial Osteotomy With or Without Concomitant Arthroscopic Treatment of Knee Intraarticular Lesions.

Intraarticular knee lesions are often in patients with early stages of osteoarthritis. The most frequent findings are degenerative meniscus/meniscal tears and cartilage degeneration. Degenerative meniscal lesions or meniscal tears are often incidental findings without any complains from patients. In the current literature there is no evidence for good clinical outcomes after arthroscopically treatment degenerative meniscus. Cartilage injuries are common in osteoarthritic knee and depending on grading of chondromalacia are usually treated by microfractures. By this time the choice of performed surgery depends on surgeons personal assessment. The investigators believe that concomitant intraarticular procedures added to HTO will provide better clinical outcomes.
