Filter by:The functional flexion axis of the knee can be established by computer-assisted intra-operative data, through range of motion techniques, not specific landmarks such as epicondyles.
Patients who undergo general anestheesia for total knee arthroplasty pften have sever postoperative pain which hinders their rehabilitation. Nitroglycerin patches have been found to cause alleviation of pain especially when used in conjuction with morphine. Therefore we propose placement of a nitroglycerin patch after total kneee arthroplasty surgery and see how it affects pain scores or causes less nedd for morphine after surgery.
The purpose of this study is to determine whether intraoperative computer-assisted navigation improves prosthetic implant positioning as compared to conventional intraoperatve instrumentation in Total Knee Arthroplasty (TKA).
Total knee arthroplasty (TKA) is performed more than 300,000 times a year in the United States, most often for osteoarthritis (OA). While pain is predictably reduced, function does not typically ever reach that of age-matched, uninjured subjects. Quadriceps weakness has been implicated in the development and progression of knee OA and is a significant problem after TKA. Voluntary exercise has been ineffective at restoring quadriceps strength after TKA. The aims of this study are: 1) to assess the effectiveness of high-level neuromuscular electrical stimulation as an adjunct to ongoing intensive, early rehabilitation in restoring quadriceps strength and improving the functional outcome after primary TKA, and 2) to identify the physiological and morphological bases for improvements in quadriceps strength and functional outcome.
