Background: Osteoarthritis (OA) of the knee, generally referred to as degenerative joint disease of the knee, is frequently brought on by wear and tear as well as the gradual loss of articular cartilage. Most often, it affects the elderly. One of the main reasons of disability in older adults is knee osteoarthritis (OA), which is characterized by lessened knee flexion angles (KFA) and external knee flexion moments (KFM) during the stance phase. Objective: The purpose of this cross sectional study was to determine assessment of Quadriceps muscles potency among patients with Knee Osteoarthritis. Methodology: This cross sectional learning was held in Gujrat, Pakistan. Data of 267 patients was taken from Aziz Bhatti hospital, Allied hospital and from City hospital. Manual muscle testing was used to check the quadriceps power in knee osteoarthritis patients Results:267 participants were added in study. Both males and females were added with diagnosed knee osteoarthritis. Grade 3 commonly results in knee osteoarthritis patients with weak quadriceps strength. Grade 4 and 5 are less in common. Conclusion: Quadriceps strength strikingly declines in older persons with knee osteoarthritis. Grade 3 is constantly noticed. Patients among grades 4 and 5 are also suffering but with a lesser amount of percentage
