1. An unicompartmental retractor for use in performing knee surgery comprising:
- (a) a handle having a longitudinal axis and having a flat section defining a first plane and,(b) an integral tip extending from said handle and having first, second and third sections, said first section having a planar portion disposed at an angle between 43.5°
0 and 46.5°
to said first plane, said second section following an arcuate path having a radius between 1.3 inches and 1.7 inches and said third section following a straight line path disposed at an angle of 5°
±
2°
0 to a second plane perpendicular to said first plane and extending in a direction away from said handle and terminating below said first plane such that the included angle between said path straight line and said first plane is between 83° and
87°
