A system for evaluating surgical knot formation is disclosed. The system includes a first surgically relevant object, a pressure sensor, and at least one pair of suture ends passing through the pressure sensor and the first surgically relevant object. The system also includes a controller coupled to the pressure sensor and configured to 1) transform signals from the pressure sensor into a pressure map having pressure magnitudes from a plurality of locations on the pressure sensor corresponding to one or more knots which may be formed in the at least one pair of suture ends and 2) format the pressure map for display.
