Twenty\u2010one patients undergoing simultaneous bilateral primary total knee replacements were randomized prospectively to perform the surgery via a medial parapatellar approach on one knee and midvastus approach on the other knee. All of the patellae were resurfaced. Preoperative, early and late postoperative (mean 22\u00a0month) skyline views of the patellae were taken. We found that preoperative 2.24\u00b0 lateral tilt of patella had not changed by time at the midvastus side (2.95\u00b0 and 2.57\u00b0). Moreover, preoperative 0.48% lateral subluxation of the patella for midvastus approach had not changed (1.48% and 1.67%). Although 2.19\u00b0 patellar lateral tilt had not significantly changed at the early postoperative period, which was performed via medial parapatellar approach, there had been a significant increase to 5.38\u00b0 by time (<jats:italic>P<\/jats:italic>=0.037) compared to the preoperative radiographs. Additionally, the preoperative lateral subluxation of the patella (0.57%) at the medial parapatellar side had increased to 5.43% at the early (<jats:italic>P<\/jats:italic>=0.009) and 5.62% at the late (<jats:italic>P<\/jats:italic>=0.012) postoperative measurements. Midvastus approach is superior to medial parapatellar approach concerning the late patellar tracking.<\/jats:p>","DOI":"10.1007\/s00167-004-0605-6","type":"journal-article","created":{"date-parts":[[2005,3,29]],"date-time":"2005-03-29T12:46:24Z","timestamp":1112100384000},"page":"654-657","source":"Crossref","is-referenced-by-count":20,"title":["Time dependent changes in patellar tracking with medial parapatellar and midvastus approaches"],"prefix":"10.1002","volume":"13","author":[{"given":"Gurkan","family":"Ozkoc","sequence":"first","affiliation":[{"name":"Department of Orthopedics and Traumatology Adana Medical Center Baskent University School of Medicine Adana Turkey"},{"name":"Adana Uygulama ve Arastirma Merkezi Baskent Universitesi Tip Fakultesi 01250 Dadaloglu Mah.39.Sok.
