Development and evaluation of an instrumented linkage system for total knee surgery.

摘要: The principles and application of total knee surgery using optical tracking have been well demonstrated, but electromagnetic may offer further advantages. We asked whether an instrumented linkage that attaches directly to the bone can maintain accuracy systems be quicker, more convenient, less expensive use. Initial testing a table-mounted digitizer navigate drill guide for placing pins mount cutting demonstrated feasibility in terms access availability. A first version (called Mark 1) designed fix was constructed software written carry out complete replacement procedure. results showed system largely fulfilled these goals, some surgeons found visual display pin placement difficult time consuming. As result, second K-Link) develop concept. User-friendly flexible developed facilitating each step quickly accurately while guides facilitated. concluded could useful potentially lower-cost option current possibly other surgical procedures.
