Purpose : To compare the short-term clinical results of mini-midvatus minimally invasive total knee arthroplasty(TKA) with quadriceps-sparing minimally invasive TKA.
Materials & Methods : Between August 2005 and February 2006, 23 bilateral (46 knees) minimally invasive total knee arthroplasties were performed simultaneously using quadriceps-sparing surgical technique at one side and mini- midvastus minimally invasive technique at the contralateral side. The same surgeon performed all the operations with the same type of prosthesis(Nexgen LPS-flex Total Knee System) using MIS quadriceps-sparing instrument. The pos- toperative clinical and radiological results were analyzed in each group.
Results : There were no significant differences between the two groups in the operating time, total blood loss, length of skin incision, radiological results and postoperative HSS scores at 8 weeks and 1 year follow-up(p>0.05). Also, there were no differences in the postoperative range of motion and pain score assessed by visual analog scale at 1 day, 3 days, 7 days, 14 days, 8 weeks and 1 year follow-up(p>0.05).
Conclusion : Compared to quadriceps-sparing TKA, mini-midvastus minimally invasive TKA revealed no significant differences in the short-term clinical and radiological results. Therefore, it can be considered as an effective, alternative minimally invasive technique.
