    This study compares clinical and imaging outcomes in patients with mild to moderate patellofemoral joint osteoarthritis undergoing two types of TKA.

  • 2

    107 knees underwent cruciate-retaining TKA, while 109 knees received posterior-stabilized TKA, both without patellar resurfacing.

  • 3

    The PS group exhibited a higher incidence of anterior knee pain compared to the CR group, with significant differences in range of motion.

  • 4

    No significant differences were found in postoperative Knee Society Score, WOMAC, or radiological evaluations between the two groups.

  • 5

    The study concludes that TKA without patellar resurfacing can yield excellent early clinical and radiological outcomes regardless of prosthesis type.
