All patients gave Arthroscopy is one of the most common surgical procedures their informed consent to enrolment after receiving adequate used worldwide in knee OA [11]. Annually, there are about one information concerning the study (characteristics of the study, million such surgeries performed in the United States and in benefits and possible adverse effects). Before enrolment, all Sweden (population 9.5 million), the corresponding number participants attended a training program to familiarize them being about 35,000 [12,13]. Nevertheless, recent studies have with the study objectives and treatment plans. Eligible patients questioned its usefulness [14]. From a systematic review and were randomized using a computer-generated list of random meta-analysis of arthroscopic surgery with debridement, and/ numbers (Research Randomizer Form v 4.0).
