Summary
Total knee arthroplasty retaining all ligaments shows comparable knee proprioception to healthy knees. This study compared patients with bicondylar sledge prostheses to controls, finding similar proprioceptive performance.
Area of Science:
- Orthopedics
- Biomechanics
- Rehabilitation
Background:
- Proprioception is crucial for knee joint stability and function.
- Bicondylar sledge prostheses are used in total knee arthroplasty (TKA).
- The impact of TKA preserving intraarticular ligaments on proprioception requires further investigation.
Purpose of the Study:
- To evaluate knee proprioceptive performance after bicondylar sledge prosthesis implantation.
- To compare proprioception between surgically treated knees, contralateral knees, and healthy controls.
Main Methods:
- Fifteen patients received bicondylar sledge prostheses with all intraarticular ligaments retained.
- Clinical evaluations used standard scoring systems.
- Proprioceptive testing involved sway measurements during single-leg stance on a force platform, with 11 healthy subjects as controls.
Main Results:
- Clinical scores differed significantly between patients and controls, except for gait, muscle force, and pain.
- No significant difference in sway measurements was found between patients' surgically treated legs and healthy controls.
- No significant correlation was observed between clinical scores and sway measurement results.
Conclusions:
- Total knee arthroplasty that retains all intraarticular ligaments achieves proprioceptive results comparable to healthy individuals.
- Sway measurements may not fully capture the clinical functional outcomes after this type of TKA.
