Sixty Subjects of both genders aged 40-60 years old with grade 2 knee osteoarthritis years will diagnosed by orthopedists they will assigned randomly into three groups: * Group A Will receive WBV Training with frequency of 35 Hz, peak-to-peak amplitude of 4- to 6-mm Vertical sinusoidal vibration, and the total exposure time of 30 minutes (vibration 60 seconds, interval rest 60 seconds) in addition to traditional exercises,3 sessions per week for four weeks. , A vibration device (My7™ model Personal Plate, Power Plate, Northbrook, IL, USA) will used in all WBVT sessions. * Group B will receive Biobex training and traditional exercises Total time of training was 10 minutes each set is 3 minutes with 20-second rest intervals * Group C Patients will receive only traditional exercises, 3 sessions per week for four weeks. a good general guideline is 2-3 sets of 10-15 repetitions for each exercise.
