Abstract
An arthroscope is constructed within a sheath having a cross-sectional configuration generally rectilinear, but with the longer sides slightly arcuate. The dimension of the sheath along the minor axis of its cross-section is as small as possible to accommodate the systems, e.g., lens, irrigation, instrument channel, included in the instrument. The radius of curvature of the arcuate sides is selected to approximately match the contours of the joint bones of interest, e.g., the femoral condyles and the tibial plateaus.
