Predictors for collateral ligament release in knee replacement surgery

In a total knee replacement operation, certain navigational predictors can determine the need for collateral ligament release, according to a new study.

Research printed in the Journal of Bone and Joint Surgery claims the need for release of collateral ligaments during total knee replacement operations has risen in over 50 per cent of procedures.

This increase has been attributed to a "lack of standardised quantitative indicators" for determining their necessity.

Two predictors have been highlighted for the need for collateral ligament release, namely the ability to restore the range of motion axes before bone resectioning and discrepancies in the "measured medial and lateral joint spaces after the tibial osteotomy".

According to the researchers: "The use of the two navigational predictors meant that only ten of the 93 patients required collateral ligament release to achieve a stable, neutral knee."

The Society of Chiropodists and Podiatrists recently claimed that wearing high heels can cause knee problems, which could lead to the need for joint replacement procedures.
