Objective To investigate the clinical difference between midvastus and medial parapatellar approaches in total knee arthroplasty. Methods Twenty-five patients undergoing bilateral total knee arthroplasty in this hospital from January 2009 to January 2010 were retrospectively studied. One randomized side of each patient was treated using the midvastus approach and the other side using the medial parapatellar approach.The operation duration, postoperative drainage amount,range of motion 6 weeks after operation, time to resume straight leg raises and the VAS score of each knee in the postoperative 1,2,3 and 6 days were observed. Results The midvastus approach group far outperformed the medial parapatellar approach group in the time to resume straight leg raises and VAS scores(P<0.05). However，they had no significant difference in the drainage amount,operation duration and range of motion 6 weeks after operation (P >0．05). Conclusions Compared with midial parapatellar approach, the midvastus approach in total knee arthroplasty causes less pain postoperatively, takes less time to resume straight leg raises and brings about quick recovery to knee function.
