Introduction |
|
| Surgical techniques used in
performing Total Knee Arthroplasty (TKA) have been essentially
unchanged for over 20 years. The patient is positioned
supine and a 20-30 cm (8-12 inch) incision is made with the leg
extended. The patella is then everted and the knee is flexed
with retractors used to expose the arthrotomy site. While
this extensive exposure aids in aligning the knee enhancing visualization
of landmarks and allowing the use of bulky instruments to complete
the bone preparation for implants, it imposes significant
trauma to the quadriceps mechanism and soft tissue. |

|
|
| A Minimally Invasive Total Knee
Replacement (MIN TKA) procedure has been developed utilizing
the new Suspended Leg Technique. The patient's
leg is placed in a leg holder and flexed over the edge of a
surgical table allowing the weight of the leg to distract
the joint and push tissue away. Sterile draping is
possible and a mobile, sterile field is created that allows sequential
flexion and extension as needed. The surgeon can be in
a sitting or standing position during the procedure. |
