Dynamic Measurement of Patellofemoral Compression Forces: A Novel Method for Patient-Specific Patella Resurfacing in Total Knee Replacement

Functional dissatisfaction following total knee replacement (TKR) is recorded as high 20%. The majority of these patients report anterior pain (AKP) the main source dissatisfaction. Elevated patellofemoral compression forces and soft tissue extensor hood strain have been implicated in generation significant AKP. A novel method assessing measuring dynamically native resurfaced patella for TKR four different quadrants described. Results are reported from an vitro model cadaveric studies knee. Patellofemoral shown to be characteristic consistent over repeated assessments Placement a significantly alters this pattern. Furthermore, over-stuffing or under-stuffing also nature magnitude forces. These may lead improved understanding AKP TKR, using assessment tool presents opportunity more effectively balance third space, reproduce forces, subsequently reduce TKR.
