Abstract

Background: The migration of the Tibio-femoral Contact Point of the Femur with respect to the tibial plateau is altered by the rupture of the Anterior Cruciate Ligament and again changed after reconstructive surgery, as shown by sequences of video fluoroscopic knee images during extension. Besides, subjective satisfaction of reconstructed knee function is assessed using the The Lysholm score and the Tegner activity scale. We have tested whether the subjective score is correlated to objective and dynamic joint anteroposterior movement after Anterior Cruciate Ligament reconstruction.

Methods: The Lysholm score and the Tegner activity scale was obtained by personal interviews and we have designed a new simple procedure (called CINARTRO) with interactive determination of Tibio-femoral Contact Point in each one of 30 video fluoroscopic images during extension to output clinical reports. Contact Point migration is expressed as percentage of tibial plateau length. We have applied the method to 5 male patients whose Tegner activity score was 7 (competitive amateur sportsmen) and 25 (SD 3.6) years old.

Results: Combination of subjective and clinical objective (quantitative & dynamic) estimation of Tibiofemoral Contact Point migration showed no correlation in the 5 patients: -0.46

Conclusions: Due to the independence of subjective and objective dynamic evaluations of Anterior Cruciate Ligament reconstruction, both should be included to guide follow-up. This is because restricted Tibiofemoral Contact Point migration and eventually associated increased surface stress appear to have no subjective immediate consequences on patient comfort.
