Abstract
Objective: To evaluate the effect of the length of the skin incision for minimally invasive total knee arthroplasty (MIS TKA) through a mini-midvastus approach.
Methods: We compared the early results of 100 MIS TKAs performed through skin incisions shor ter than 10 cm (Group I) and 10 cm or more in length (Group II). There were 51 knees in Group I and 49 knees in Group II. The evaluation included operation time, blood loss, range of motion, clinical score, alignment of components, rehabilitation, complications, and subjective patient satisfaction.
Results: At 3 months postoperative flexion was greater in Group I than in Group II, and rehabilitation was more rapid in Group I, but no significant differences in any other parameters were found between the two groups.
Conclusion: MIS TKA through the smaller skin incisions yielded better early results in this study.
