Abstract

Purpose: This prospective study was designed to evaluate the postoperative changes in soft tissue balance between Mobile- Bearing (MB) and Fixed- Bearing (FB) Posterior- Stabilized (PS) Total Knee Arthroplasty (TKA) with identical femoral components.
Methods: A total of 40 knees in 37 consecutive patients were randomly allocated to undergo either an MB PS TKA or an FB PS TKA (20 knees each). We investigated the correlation between the intraoperative soft tissue balance as evaluated by an offset- type tensor and the 1-year postoperative coronary ligament balance as assessed by stress radiographs.Results: In terms of soft tissue balance, there were no differences in the intra- and postoperative values between the groups. At extension, the close correlation between intra- and postoperative soft tissue balance was seen in both inserts. The correlations at 90° of flexion, on the other hand, were maintained in the MB group and lost in the FB group.Conclusion: Our results suggest that the intraoperative setting of soft tissue balance may change postoperatively. However, using this PS design, the MB insert could be more stable than the FB insert in terms of maintaining the balance postoperatively. This result may contribute to additional improvements in surgical techniques, particularly in adjusting the soft tissue balance to obtain a better outcome after TKA.
