Trial joint inserts may have posts that slide along a base, compressing or extending a resistance member, such as a spring, as the post slides. During joint replacement surgery, a surgeon can test resistance members with different amounts of resistance using a trial insert, identify a suitable resistance for the resistance member, and then select a permanent insert with a resistance member having the desired resistance. The systems, devices, and methods of this application allow a surgeon to provide an individualized joint replacement for a patient. |
