Comparison Between Brainlab Knee 3 Computer-assisted Navigation Systems and Conventional Instruments in TKA: a Prospective Cohort Study.

Total Knee Arthroplasty Clinical Trial

Official title:
Comparison of Accuracy and Clinical Outcomes Between Brainlab Knee 3 Computer-assisted Navigation Systems and Conventional Instruments in TKA: a Prospective Cohort Study

Clinical Trial Summary

This is a a prospective cohort study. According to the inclusion criteria, volunteers were recruited from patients undergoing total knee arthroplasty. The patients are devided into two groups: the conventional TKA,the computer-assisted surgery(CAS) using Brainlab Knee 3 system.The differences of postoperative alignment,operative time,blood loss will be studied between the two groups.Clinical and functional evaluation using the scoring system of HSS(Hospital for Special Surgery) score, Western Ontario and McMaster University osteoarthritis index (WOMAC), Forgotten joint score(FJS-12) will be compared between the 2 groups,after surgery, and at the follow-up of 3 months、6 months and 12 months.

Clinical Trial Description

According to the inclusion criteria, patients receiving primary total knee arthroplasty were recruited and divided into two groups after doctor-patient joint decision: the traditional group underwent prosthesis placement using traditional intramedullary positioning method;The navigation group performed surgery using the Brainlab Knee 3 navigation system.Informed consent was signed after grouping. All patients were operated by the same knee prosthesis system. Both groups underwent the same procedures such as the installation of the soft tissue adjustment, prosthesis placement, wound closure and so on.All patients were given the same perioperative treatment, such as hemostasis, anti-infection and analgesia, and routine postoperative rehabilitation exercises. The full length anteroposterior and lateral radiographs of both lower extremities in weight-bearing position were taken preoperatively and one week postoperatively.The differences of postoperative alignment,operative time,blood loss will be studied between the two groups.Clinical and functional evaluation using the scoring system of HSS(Hospital for Special Surgery) score, Western Ontario and McMaster University osteoarthritis index (WOMAC), Forgotten joint score(FJS-12) will be compared between the 2 groups,after surgery, and at the follow-up of 3 months、6 months and 12 months. ;
