An in-joint pump and control device comprising a pump and an in-joint sensor. The pump is configured to convey fluid to a body joint surgical site. The pump has an algorithm associated therewith to make calculations and to assist in controlling the operation of the pump. The in-joint sensor is operatively associated with the pump by at least a communication member. The in-joint sensor comprises a sheath, an integration member attached to the sheath, a pressure sensor connected to the integration member, and a temperature sensor adjacent the sheath. The pressure sensor is adapted to provide pressure information to the pump via the communication member. The temperature sensor is also adapted to provide temperature information to the pump via the communication member.
