Minimally Invasive Total Hip Replacement and Perioperative Management:
Early Experience (Waldman, J South Ortho Assoc, 2002)
• 32 Posterior MIS THA’s
• “Mobile Window” skin incision
• Fascial incision extended 3 cm prox & distal
• Minimum 7 month F/U
• Mean D/C from Hospital = 3 days
• No complications

“Mini-Incision THA: A Comparative Assessment of Perioperative Outcomes,”
(Wenz, Orthopedics, 2002)124 MIS vs 62 direct lateral approaches
• MIS Advantages
• Earlier Ambulation
• Less transfer assistance
• More favorable discharge dispositions
• Decreased transfusion requirements
• Better functional recovery

“Mini-Incision Technique for THA with Navigation”
(DiGioia, J Arthroplasty, 2003)
• Patient Population
• - 33 Standard Incision (20.2 cm)
• - 33 Mini-Incision (11.7 cm)
• Improved limp, stair climbing at 3 months
• Improved limp, stair climbing, distance walked at 6 months
• No difference pain, function, ROM

“MIS vs Standard THA: A 2-Year Prospective Study with Age-Matched,
Historical Controls” (Swanson, 2003 AAOS Presentation)
• Shorter operative time
• Less blood loss
• Less pain
• Shorter hospital stay
• Quicker return to function
• Fewer complications (esp. post-op confusion)
• Reproducible component position
