About

Comparison of postoperative patient's joint awareness as well as clinical and radiological outcomes between fixed- and mobile-bearing total knee arthroplasty of which the prosthesis is coated with Titanium-nitride.

Full description

Despite numerous comparison studies between mobile- and fixed-bearing TKA as well as several comparison studies regarding clinical and radiological outcomes using titanium-nitride(TiN) prosthesis, there has been no study on postoperative joint awareness despite mobile- and fixed-bearing TKA using TiN prosthesis.
