A method and apparatus are disclosed for securing an arthroscopic cannula in place during arthroscopic surgery. The method and apparatus seal the arthroscopic incision to mitigate leakage of fluid from the joint and seepage of the fluid into surrounding tissue. Reducing leakage of fluid during surgery reduces consumption of saline to insufflate the joint, and improves safety in the operating room by reducing accumulation of fluid on the operating room floor. Reducing leakage and tamping the incision also reduces the likelihood of expulsion of the cannula under pressure from the joint. Reducing seepage of fluid into surrounding tissue also reduces stiffening of the joint during surgery which can interfere with manipulation of the joint and instruments to desired positions during surgery. Reducing seepage of fluid into surrounding tissue also reduces the likelihood of complications or extenuating circumstances during surgery due to migration of fluid through expulsion of the cannula by reducing expansion of surrounding soft tissue during manipulation of instruments and the cannula during surgery, and improves patient recovery.
