  • <p>This study, comprising 7 separate papers, is concerned with treatment of medial gonarthrosis.</p> <p>Results after high tibial osteotomy were found to deteriorate 8-9 years after surgery. The best results were seen in knees with preoperative Stage I or II osteoarthrosis and valgus deviation after osteotomy.</p> <p>The rehabilitation period after high tibial osteotomy is long, recovery of the average thigh muscle torque was first seen after 12 months. Stable internal fixation with early mobilization does not seem to be advantageous in this respect.</p> <p>Gait analysis showed signs of insufficient rehabilitation persisting 8-12 months after high tibial osteotomy, with unimproved maximum gait velocity and reduced stride length at constant maximum velocity.</p> <p>Rehabilitation with restitution of muscle torque was faster after unicompartmental arthroplasty and gait parameters did improve.</p> <p>An "anatomical" type of unicompartmental prosthesis seems to be more susceptible to load, with changed strain elicited in external rotationcompared to a meniscus bearing prosthesis.</p> <p>Knees with medial osteoarthrosis showed less rotation clinically duringmotion than healthy knees. The rotation was not significantly affected by a unicompartmental arthroplasty.</p> <p>A radiographic method for detection of prosthetic migration, using tantalum balls implanted in the skeleton, was developed and tested on 20 patients.</p>
