VAS scale will be used to assess pain.10 meter walk test,timed up and go test, stair climb test and Internatıonal Physical Actıvıty Questionnaire(IPAQ) will be used to assess functional performance.Knee and ankle muscle test and range of motions will assessed and quality of life will evaluated with SF-36 short form scale.All measurements will be made again after 6 weeks.
