Overview

Brief Summary

Beside the current standard of classical mechanical alignment of total knee replacements, increased interest is being shown in anatomical alignment. However, no surgical technique is capable of controlling the stability of the joint in midflexion. The purpose of the present study was to present and evaluate a new surgical technique, which aims to reduce the need for soft-tissue release and optimize stability in midflexion.

Eligibility Criteria

Inclusion Criteria

  • •The patients were to undergo surface replacement due to primary osteoarthritis of the knee

Exclusion Criteria

  • •Joints that had undergone open surgery beforehand (e.g. high tibial osteotomy, fracture treatment) were excluded.

Outcomes

Primary Outcomes

Measurement of midflexion instability (i.e. tibofemoral gap medially and laterally) in 30° and 60° of flexion

Time Frame: intraoperatively immediately before implantation of definite implants.

The outcome measures are given in mm.

Secondary Outcomes

  • performance of soft tissue release (yes / no) and extend of release if done.(intraoperatively)
