The present study assessed the feasibility of MIS\u2010TKA using a lateral approach for valgus knees.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Subjects comprised 26 patients with valgus knees who underwent MIS\u2010TKA using a lateral subvastus approach. Five cases required a 1\u2010cm snip of vastus lateralis obliquus, to shift the patella medially without eversion. Clinical scores and radiographic parameters of lateral MIS\u2010TKA were examined and compared with those of 26\u00a0medial MIS\u2010TKAs matched for preoperative patient characteristics.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The lateral MIS\u2010TKA group showed slightly longer operative time and larger skin incision than the medial MIS\u2010TKA group. Nevertheless, myoglobin index and pain on a visual analog scale on postoperative day 7 were significantly lower in the lateral MIS\u2010TKA group than in the medial MIS\u2010TKA group. Postoperative improvement of clinical scores was quite comparable between lateral and medial MIS\u2010TKA groups. Radiographic assessment revealed that tibiofemoral mechanical axis aligned within \u00b13\u00b0 from ideal in 24 of 26 patients after lateral MIS\u2010TKA. MIS technique\u2010related complications occurred in only 1 patient presenting with subsidence of the tibial component, due to malpositioning of the tibial component.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>From the perspectives of postoperative pain, clinical scores, radiographic accuracy, and postoperative complication rate, lateral MIS\u2010TKA achieved comparable or superior results to medial MIS\u2010TKA. This technique may offer a promising technical option that can be utilized for most patients with valgus knee deformity.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-010-1323-x","type":"journal-article","created":{"date-parts":[[2010,11,17]],"date-time":"2010-11-17T14:05:28Z","timestamp":1290002728000},"page":"973-979","source":"Crossref","is-referenced-by-count":21,"title":["Clinical
