Mid-term results show no significant difference in postoperative clinical outcome, pain and range of motion between a well-established total knee arthroplasty design and its successor: a prospective, randomized, controlled trial
To compare the clinical outcomes of the PFC Sigma and Attune TKA systems specifically after 2 years post-surgery.
Key Findings:
No significant differences in clinical outcomes, pain levels, or range of motion between the Attune and PFC Sigma groups at 2 years, highlighting the equivalence of both designs.
Both implants showed similar effectiveness in managing severe osteoarthritis.
Interpretation:
The modifications in the Attune TKA design did not lead to improved clinical outcomes compared to the established PFC Sigma system.
Limitations:
Non-blinded study design may introduce bias, potentially affecting the perceived outcomes.
Loss to follow-up could affect the robustness of results, as it may skew the data.
Conclusion:
Both TKA designs yield comparable mid-term clinical outcomes, suggesting that the newer design may not provide significant advantages over the established model, which is important for clinical decision-making.
