Patients who undergo knee manipulation after total knee replacement surgery experience substantially improved range of motion, flexion and other knee functions, reports The Journal of Bone and Joint Surgery. While the patient is under anesthesia, a doctor performs the manipulation to relieve stiffness when other postsurgery rehabilitation efforts have failed.
Over 20 percent of patients who undergo surgery for a total knee replacement, called arthroplasty, experience a postsurgery reduction in their range of motion due to stiff knees, which has the ability to impair their quality of life. In such cases, a physician typically performs the noninvasive procedure of knee manipulation under anesthesia. The manipulations are most effective when performed within the first 12 weeks after the knee arthroplasty, notes the Journal of Bone and Joint Surgery.
