is illustrated this disclosure extends to cartilage trimmers for other joints the cartilage trimmer 20 is configured to resect torn or damaged cartilage in the joint space 26 in this example the cartilage trimmer 20 is used to resect a tear 32 in a meniscus 34 the cartilage trimmer 20 can be used to resect other cartilage structures including articular cartilage as generally mentioned above the cartilage trimmer 20 is configured to be assembled during surgery in the example of fig1 2 the cartilage trimmer 20 is assembled by first inserting the guide pin 22 into the joint space 26 in this example the guide pin 22 is inserted into the joint space 26 by way of a tunnel 36 formed in the tibia 30 once the guide pin 22 is positioned in the joint space 26 the cutter 24 is deployed arthroscopically as generally shown in fig1 and connected to the guide pin 22 by a tool 38 such as a grasper as generally shown in fig2 the assembled cartilage trimmer 20 is then used to resect the tear 32 because cartilage is relatively soft a surgeon typically maneuvers the guide pin 22 by hand however in some examples the guide pin 22 can be rotated using an automated tool such as a drill once the tear 32 is resected the cutter 24 can then be removed from the guide pin 22 for example using the tool 38 the guide pin 22 and the cutter 24 are then separately removed.
