Knee Replacement after High Tibial Osteotomy

A new German study has just been published looking at the outcomes of knee replacements done after a High Tibial Osteotomy compared with uncomplicated first time joint replacements.

Previous studies looking at this question had found higher rates of complications and an increased duration of surgery.

The findings from this study are:

No significant difference in length of operation
No significant difference in complication rate.
X-ray assessment at follow up showed no significant difference between the groups.
The High Tibial Osteotomy group had a lower range of motion. The average works out at 9.5 degrees less movement

The follow up time for the study was an average of 7 years making it difficult to comment on failure rates in the long term. The medium term results were on the whole fairly similar with the exception of joint range of motion.

  1. There are certain concerns in Post High Tibial osteotomy TKR...
    The varus/ valgus alignment and adhesions need to be taken care of; but the most important is rotational mal-alignment.
    If the component is misplaced in internal rotation, it may lead to serious limitation in movements and patellar tracking.
