Optoelectronic cinematic analysis has already proven useful in the investigation of patients with a knee replacement however neither patellar tracking nor the various positional parameters relevant to instability such as patellar tilt and/or patellar shift have ever been specifically evaluated using this type of system The aim of this research was to validate the relevance of this type of cinematic analysis in order to use it in the evaluation of the main factors underlying patellar instability Six freshfrozen anatomical specimens were studied The data were acquired using the Motion Analysis® system Statistical analysis reveals a good reproducibility of measurements Our protocol based on an optoelectronic acquisition system has an accuracy of 023 mm for shift and of 04° for rotation which is calculated by integrating the various experimental parameters and instrumental features specific to the Motion Analysis® system The results are consistent with published results which further attests to the validity and the efficacy of the protocol and encourages us that this protocol is suitable for the in vitro study of patellar kinematics
