Abstract
Background: Osteoarthritis of the knee is the most common cause of functional impairment in the elderly. A complete knee arthroplasty is the most common knee operation for patients with advanced osteoarthritis. A complete knee arthroplasty is a surgical procedure that is used to treat osteoarthritis in its most severe form." Rheumatoid arthritis, advanced degenerative arthritis, and other forms of this type of osteoarthritis fall under this category. This way of treating different types of arthritis is both highly successful and completely risk-free. MP-TKR and PS-TKR designs have been proven to be beneficial only through a little amount of research so far. So, the aim of this study was to compare the mean range of motion by using two different types of implants i.e. high flexed posterior stabilized implant and medial pivot implant. Objectives: To compare the mean range of motion, in patients with advanced arthritis, treated with total knee arthroplasty, by using two different types of implants i.e. high flexed posterior stabilized implant and medial pivot implant. Study design: It is Randomized Comparative Trial. Setting: Department of Orthopedic Surgery at Shifa International Hospital, Islamabad. Subjects: A total of 62 patients were included in our study, which is divided into 2 groups, comprising of 31 patients in each group.
