[Development and application of computer aided joint surgery systems].

OBJECTIVE
To investigate the development and application of the computer aided surgery systems in the joint surgery field.


METHODS
The literatures were extensively reviewed to analysis the usefulness of current active, semi-active and passive computer aided surgery systems in solving the clinical problems of joint surgery.


RESULTS
Several computer aided surgery systems have met the high technique demands, such as the precision of anatomical position and orientation, the accuracy of normal limb alignment restoration, the optimum of instrumentation control in arthroplasty, peri-articular osteotomy and minimally invasive procedure.


CONCLUSION
Computer aided joint surgery systems facilitate precise surgical techniques to achieve ideal operative outcome.
