Abstract

Background 

Total knee arthroplasty has been regarded as the primary surgical procedure for relieving severe pain in the last stage of degenerative arthritis and experiencing better functional outcomes. many previous studies have been described the effect of posterior tibial slope on functional outcome, but many debates exist.

Objectives 

To find changes of posterior tibial slope in total knee arthroplasty.

Patients and Methods

Our study includes 50 patients (50 knees) who underwent Cruciate Retaining-Total knee Replacement (CR-TKR) from 10 January 2018 to Nov2019. Posterior tibial slope (PTS) was measured on lateral x-ray. According to the oxford knee score, the functional outcome and the posterior tibial slope were measured preoperatively and postoperatively for each patient.

Results

Fifty patients underwent CR-TKR. Preoperative PTS and oxford knee scores were 11.7 and 11.72, respectively. Postoperative PTS and oxford knee scores were 9.3 and 39.64, respectively. We divided into Group A: PTS up to 9(24 cases) and Group B PTS more than 9 (26). We analyzed the relationship between PTS and functional outcome according to the oxford knee score. 

Conclusion

Clinical improvements were noticed in both patient groups after CR-TKR.
