Targeting the neutral hip-to-calcaneus axis in kinematically aligned total knee arthroplasty is feasible with fewer alignment outliers for varus osteoarthritic patients
To present the ground KA-TKA technique for varus osteoarthritic patients and compare its postoperative radiographic parameters, such as alignment and joint line orientation, with those of tibia-restricted modified KA-TKA.
Key Findings:
Ground KA-TKA technique reproduces a neutral ground MA (hip-to-calcaneus axis) with fewer alignment outliers, defined as deviations from the target alignment, compared to tibia-restricted KA-TKA.
Interpretation:
The ground KA-TKA technique offers a more individualized approach to TKA, potentially improving alignment outcomes and overall function for patients with varus osteoarthritis.
Limitations:
The study primarily focuses on radiographic simulations and may require clinical validation; the technique may not be applicable to all knee phenotypes, which could limit its generalizability.
Conclusion:
Ground KA-TKA is a feasible approach that aligns with the anatomical differences of each knee, potentially leading to better alignment outcomes and improved patient satisfaction in varus osteoarthritic patients.
