[Long term follow up of patients with knee osteoarthritis after high tibial osteotomy].

OBJECTIVE
To investigate the clinical result of knee osteoarthritis after high tibial osteotomy (HTO) in long term follow-up.


METHODS
107 patients of knee joint osteoarthritis performed with high tibial osteoarthritis between 1983 and 2000 was followed up. Standing anteroposterior radiograph of knee were taken for every patient.


RESULTS
The clinical results of 137 knees (88%) were rated as good at 1 to 5 years follow-up. 21 knees were good at 5 to 10 years follow-up. And 5 knees were good at lest 10 years follow-up. Only one patient was done TKA 8 year after HTO.


CONCLUSIONS
The patients done HTO show excellent clinical results in short time follow-up. And the results of most patients was maintained in intermediate and long-term follow-up. The internal fixition allow patients early activity and recover quickly.
