Abstract

The results of total knee arthroplasty (TKA) after high tibial osteotomy (HTO) and problems encountered during the operation were investigated in 23 patients (28 knees). HTO was performed by Coventry's method in 18 knees and by Maquet's method in 10 knees. The mean interval from HTO to TKA was 86 months (range, 3 to 288 months) and the mean follow-up period after TKA was 25 months (range, 6 to 116 months). Radiological evaluation showed that the proximal part of the tibia was shifted and tilted lateroinferiorly after HTO. Thus, a tendency to patella infera was observed. Lateral shift of the proximal part of the tibia was more marked with Maquet's method than with Coventry's method (P <0.01). Posterior inclination of the tibial articular surface before TKA was smaller in the patients who gained a range of motion of 90°or more after TKA than in those with less than 90°(P <0.05). In patients with 70 points or more on the three-university score after TKA, there was no change in the joint line level between before and after TKA, while the joint line was significantly lower after TKA in those with less than 70 points (P <0.01). When TKA is done after HTO, various technical problems may influence the outcome, such as correction of the soft tissue imbalance, in addition to difficulties with patellar eversion and exposure of the proximal part of the tibia. The clinical results of TKA after HTO tend to be slightly inferior to those of primary TKA, probably because of such technical problems.
