In a prospective study of 45 gonarthrosis patients treated with total knee arthroplasty, we performed gait analysis with the Vifor system preoperatively and 6 months and 2 years postoperatively. An evaluation was made of the relationship between dynamic measurements of knee joint load and static, radiographic measurements of alignment. Correlations were found between the knee joint moments in the frontal plane and the Hip-Knee-Ankle (HKA) angles on all measurement occasions, likewise between changes of moments and changes in HKA by the operation. Thus, static alignment reflects the loading conditions during gait.

The in vivo kinematics of the knee in 7 patients with moderate medial gonarthrosis was analyzed before and 6 months after high tibial osteotomy using roentgen stereophotogrammetric analysis. The inclination of the femorotibial helical axis of rotation did not change with knee flexion or after surgery. The femorotibial rotation increased after surgery. No consistent change in patellar position after surgery was found. Patella translated laterally as the knee was flexed with a maximum patellar translation of about 15 mm and rotated internally with a maximum patellar internal rotation of about 15 degrees. There was no significant change in patellar translation or rotation after surgery. There was a good concordance regarding the size of the tibial wedge removed during surgery, calculated from the Hip-Knee-Ankle radiographs and from the roentgen stereophotogrammetric measurements.

A total of 32 distal femoral osteotomies performed between 1971 and 1993 were evaluated, with a follow-up of 8 (2-23) years. Indications were lateral gonarthrosis in 23 cases (group I), and there were a variety of other indications in 9 cases (group 2). Twenty-six of the patients were submitted to revision surgery. Eleven operations were performed as a result of complications, such as pseudarthrosis (5), deep infection (3), and stiff knee (3). The remaining 16 were removals of fixation devices and they were not considered complications. Clinical results were evaluated based on different clinical scores (HSS, Lysholm, and Tegner) and NHP (Nottingham Health Profile), and there were 10 cases with good or excellent results. Results were better if the postoperative HKA angle (Hip-Knee-Ankle) was within 0-8 degrees of varus. As accuracy of correction is of importance, and serious complications frequent, it is important to entrust cases such as these to the care of surgeons with a good knowledge of the surgical technique.
