MIS TKR Through a Mini-Mid Vastus Approach
By: Steven Haas, MD
(Excerpted from a paper Dr. Haas will present at the combined Knees Society/AAHKS Specialty Day Meeting, March 13, 2004)
¡¤ 40 consecutive Mini-TKA patients with minimum 1-year follow-up
¡¤ Mean flexion at 6 weeks improved by 19 degrees or 20%
¡¤ Mean flexion at 12 weeks improved by 4 degrees or 3.6%
¡¤ Improved ROM seen at 6 months and one year post-op
¡¤ ROM at one year post-op improved by 9 degrees or 7.7%
