Kinematic alignment possible with manual instrumentation, medially stabilized implants

摘要

Total knee arthroplasty is a successful surgical procedure that relieves pain and restores function. However, TKAhas not had the same reported patient satisfaction rates as total hip arthroplasty. Mechanical alignment was firstdescribed by John Insall in 1985 and has become the most common surgical approach for TKA, used worldwide bymost surgeons. Mechanical alignment places the implant in an average position for all patients based on apredetermined definition of acceptable alignment and has been especially successful when coupled with posteriorstabilized devices. Most implant systems and instrumentation are optimized for use with mechanical alignment.
