Objective:

To compare clinical and imaging outcomes in patients with mild to moderate patellofemoral joint osteoarthritis between cruciate-retaining TKA and posterior-stabilized TKA without patellar resurfacing.

Key Findings:
  • Higher incidence of anterior knee pain in the PS group compared to the CR group (p = 0.028).
  • Range of motion was better in PS TKA than CR TKA (p < 0.05).
  • No significant differences in postoperative KSS, WOMAC, HKA, FRA, PTA, and ISR between the two groups (P > 0.05).
Interpretation:

Limitations:
  • Study is limited to a specific population and may not generalize to all patients with knee osteoarthritis.
  • Follow-up duration was a minimum of 3 years, which may not capture long-term outcomes.
Conclusion:
