Computer-assisted TKA: greater precision, doubtful clinical efficacy: opposes.

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Controversy exists regarding the clinical benefits of computer-assisted total knee arthroplasty (TKA) despite improved precision.
• Traditional methods may be inadequate for complex knee deformities.

Purpose of the Study:

• To evaluate the clinical benefits and precision of computer-assisted TKA.
• To assess the efficacy of computer navigation in correcting complex knee deformities and improving functional results.

Main Methods:

• Utilized computer navigation for precise component placement and limb alignment.
• Quantified soft tissue release and bone cuts for gap balancing and deformity correction.
• Assessed outcomes in patients with severe deformities, obesity, and in situ hardware.

Main Results:

• Computer-assisted TKA provides precise gap equality, symmetry, and soft tissue release, especially for severe deformities.
• Accurate restoration of alignment, joint line, and offset improves functional results.
• Navigation is effective for complex deformities, obese patients, and reduces outliers.

Conclusions:

• Computer-assisted TKA offers superior precision in component placement and alignment restoration.
• The technology facilitates accurate correction of complex deformities, leading to improved functional outcomes and patient safety.
• Computer navigation enhances the safety and functional recovery of patients undergoing total knee arthroplasty.
