“The patient’s ability to ‘forget’ their joint replacement during everyday activities is an important expectation and goal of the surgery, as it reflects patient satisfaction.”¹ Research has shown that PKR patients are more likely to forget their joint replacement than TKR patients.¹, ²

The Forgotten Joint Score is used to evaluate patients’ ability to forget their joint replacement in daily life. The score ranges from 0 to 100, with 100 being the optimal score. FJS scores for PKR were significantly better than for TKR at 6 and 12 weeks, and 6 and 12 months (p < 0.001).¹

These findings were attributed to the more personalized nature of PKR, which “conserves more soft tissue and bone than TKR.“¹
