Abstract
Objectives
To compare computer-assisted total knee arthroplasty with the conventional technique in operative time.
Materials and Methods
30 patients with different degrees and forms of knee osteoarthritis were divided into 2 groups. Group 1 (15 patients) had TKA using patient specific instrumentations (PSI). Group 2 (15 patients) had TKA using the conventional technique. Operative time was measured for each patient of each group.
Results
In comparison to conventional group, patients in the PSI group had shorter operative time by 24.3 minutes which is statistically significance.
Conclusion
PSI technique has advantage over conventional instrumentation as it reduces operative time.
