The parapatellar approach is most often used, whereas the subvastus approach is a suitable alternative. Presently, it is unknown, according to true objective measurements, which of the two is most advantageous.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this prospective randomized double\u2010blind, short\u2010term trial measurements (KSS, WOMAC, PDI, VAS, ability to perform) were obtained at day 1, day 3, 1 week, 6 weeks, and 3\u00a0months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The subvastus group (<jats:italic>n<\/jats:italic> = 20) showed only significantly less extension lag direct postoperative (<jats:italic>P<\/jats:italic> = 0.04) compared with the parapatellar group (<jats:italic>n<\/jats:italic> = 20). Other scores were not significantly different. The Dynaport<jats:sup>\u00ae<\/jats:sup>knee test, an objective performance\u2010based tool, could not demonstrate significant differences. A blunt anatomical dissection was carried out in both observational and histological to support findings. A dense innervation of the distal vastus medialis was found. This is at risk employing the subvastus approach. Both approaches harm the suprapatellar bursa. The vastus medialis sheath must be detached distally to open the knee joint. No true separate vastus medialis obliquus could be identified.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Comparable to literature, only mild advantage employing the subvastus approach was found, but only early postoperative and not objectively. As this approach is also not suitable in every case, we will continue to use the parapatellar approach.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-010-1292-0","type":"journal-article","created":{"date-parts":[[2010,10,16]],"date-time":"2010-10-16T13:38:16Z","timestamp":1287236296000},"page":"943-951","source":"Crossref","is-referenced-by-count":25,"title":["Early functional outcome after subvastus or parapatellar approach in knee arthroplasty is comparable"],"prefix":"10.1002","volume":"19","author":[{"given":"Wouter L.W.","family":"van Hemert","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery and Traumatology Atrium Medical Centre PO Box 4446 6401 CX Heerlen The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel","family":"Senden","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery and Traumatology Atrium Medical Centre PO Box 4446 6401 CX Heerlen The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernd","family":"Grimm","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery and Traumatology Atrium Medical Centre PO Box 4446 6401 CX Heerlen The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthijs J.A.","family":"van der Linde","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery and Traumatology Atrium Medical Centre PO Box 4446 6401 CX Heerlen The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arno","family":"Lataster","sequence":"additional","affiliation":[{"name":"<!--<label>2<\/label>--> Department of Anatomy and Embryology Maastricht University Maastricht The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ide C.","family":"Heyligers","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery and Traumatology Atrium Medical Centre PO Box 4446 6401 CX Heerlen The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,10,17]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2004.02.027"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086\u2010200206000\u201000022"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2005.04.027"},{"key":"e_1_2_7_5_2","first-page":"1833","article-title":"Validation study of WOMAC: a health status instrument for measuring clinically important patient relevant outcomes to antirheumatic drug therapy in patients with osteoarthritis of the hip or knee","volume":"15","author":"Bellamy N","year":"1988","journal-title":"J Rheumatol"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2006.02.161"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.88B11.18052"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s004020100319"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0968\u20100160(02)00095\u20109"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11999\u2010008\u20100428\u20108"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2007.05.053"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2007.03.021"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097\u20100185(199709)249:1<135::AID\u2010AR16>3.0.CO;2\u2010Q"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198911000-00004"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.E.00107"},{"key":"e_1_2_7_16_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010007\u20100351\u20107"},{"key":"e_1_2_7_17_2","unstructured":"KortN(2007)Unicompartmental knee arthroplasty.Thesis.
