Abstract Background The incidence of patient dissatisfaction due to anterior knee pain (AKP) and patellar crepitus after total knee arthroplasty (TKA) remains a concern. However, it has been shown that improvements in the femoral component of traditional prostheses could reduce these instances of pain in the case of TKA performed with patellar resurfacing. This study aims to investigate whether TKA without patellar resurfacing can also benefit from the aforementioned femoral component modification in reducing AKP and patellar crepitus post-TKA. Methods Sixty-two patients (85 knees) who underwent TKA using the modern prosthesis and 62 age- and sex-matched patients (90 knees) fitted with the traditional prosthesis were enrolled in this study. The occurrence of AKP and patellar crepitus as well as the Knee Society Score (KSS) were consequently recorded, and the data was analyzed in order to determine whether there was a statistically significant difference between the two groups. Results The incidence of AKP was significantly lower in the study group compared with the control group at the 3-month and 1-year follow-ups (4.7% vs. 13.3% [p = 0.048] and 3.5% vs. 13.3% [p = 0.021], respectively). In addition, the incidence of patellar crepitus was also significantly lower in the study group compared with the control group at the 3-month and 1-year follow-ups (15.3% vs. 34.4% [p = 0.004] and 10.6% vs. 28.9% [p = 0.002], respectively). There was no significant difference in the KSS between the two groups. Conclusions These results revealed that TKA without patellar resurfacing will indeed benefit from the modified femoral implant design in reducing AKP and patellar crepitus, a finding that may be beneficial to surgeons who select implants for their patients when patellar resurfacing is not planned or not possible due to other reasons.
