Abstract

Purpose

The purpose of this study was to determine whether the floating platforms (FP) were superior to rotating platforms (RP) in computer-navigated total knee arthroplasty (TKA) comparing the range of motion (ROM) as well as clinical and subjective function of the knee.

Methods

This retrospective non-randomized single-centre cohort study includes 255 patients with a primary implanted computer-navigated e.motion™ (Aesculap B. Braun) TKA system, implanted because of clinical and radiological verified gonarthrosis. In 129 patients, the FP platform was implanted, and in 126 patients, the RP platform. As statistical procedures for differences between inlay type RP/FP in ROM and Knee Society Score (KSS) after 3- and 24-month follow-up, an analysis of covariance (with risk factors gender, age, BMI, preoperative ROM and preoperative KSS) was performed.

Results

Although preoperative ROM and knee society function score (KSS partII) were significantly higher in the FP group before surgery, there was no significant difference between RP and FP in ROM and KSS at 3- and 24-month follow-up.

Conclusion

The FP platform design did not have an advantage in ROM as well as in clinical and subjective knee function compared with the RP platform in computer-navigated TKA neither in early follow-up examinations at 3 months postoperatively nor at long-time follow-up at 24 months postoperatively.
