DR SHRINAND V VAIDYA'S PEGLESS FEMORAL TEMPLATE TRIAL

摘要

Achieving proper mechanical axis and rotational position of femoral component perpendicular to the tibial component throughout range of motion is necessary for long term successful outcomes of unicondylar knee replacement. Dr. Shrinand V. Vaidya's pegless template trial-P.T.T. is an orthopaedic surgical device used to determine mechanical axis, rotation and size of the femoral component. P.T.T. has two holes in anterior part which matches with femoral finishing block of respective size. P.T.T. has central watermark to determine final position of the femoral component. Position of P.T.T. is guided by tibial trial through range of motion and final position is marked over femoral condyle just anterior to the central watermark over P.T.T. Alternatively pins are inserted through the holes in PTT and removed making two holes which can be used for alignment of femoral finishing block.
