Results from this study demonstrated navigated unicompartamental knee arthroplasty was a valid surgical technique that allows for accurate prediction of predisease alignment.
Researchers conducted a single-center retrospective study of 53 patients who underwent computer navigation unicompartamental knee arthroplasty. They used navigation to record preoperative joint alignment and postoperative joint alignment, stress value and range of movement. They compared postoperative alignment with the preoperative stress values for both the postoperative varus alignment and valgus alignment as well as the preoperative WOMAC scores and Knee Society Score and the postoperative scores.
Results showed a minor systematic bias between stress value and postoperative alignment, but the difference was clinically acceptable. Investigators observed no difference seen between groups regarding the score evaluations, prosthesis size and alignment. At 2 years, the range of movement did not significantly increase.
“There was a high degree of agreement between stress value and postoperative alignment values suggesting strong validity for the surgical technique to determine optimal postoperative alignment,” the researchers wrote. – by Monica Jaramillo
