Unlabelled:
Gap-dependent total knee arthroplasty involves applying a tension force to open the joint space. Intuitively, this force is dependent on the degree of joint deformity.
Aim:
The study aims at determining the amount of force and its influence on morphological parameters.
Material And Methods:
In a group of 70 patients in whom total knee arthroplasty was performed ligament tension force was calculated and the influence of various individual morphological parameters was evaluated.
Results:
Statistical analysis showed that tension force is individual, dependent on knee deformation.
Conclusions:
Ligament tension force cannot be determined preoperatively, it requiring the use of appropriate tensioningdevices.
