Fifty-five TKAs were performed with the only difference being whether an intramedullary (31) or extramedullary (24) cutting guide was used. Pre- and postoperative tibiofemoral angle, tibial component alignment angle, and femoral component alignment angles were measured and the results were statistically analyzed. We also performed a subgroup analysis on the preoperative varus knees to determine if the presence of a varus deformity would have better results with either the intramedullary or extramedullary cutting guide. The 2-sample t test was used to compare the results of the two groups. The results showed no statistical difference in alignment of the tibial component when using the intramedullary or extramedullary guides.<\/jats:p>","DOI":"10.3928\/0147-7447-20051201-16","type":"journal-article","created":{"date-parts":[[2021,4,22]],"date-time":"2021-04-22T04:49:07Z","timestamp":1619066947000},"page":"1445-1448","source":"Crossref","is-referenced-by-count":23,"title":["Extramedullary Versus Intramedullary Tibial Alignment Guides for Total Knee Arthroplasty"],"prefix":"10.3928","volume":"28","author":[{"given":"Steven J","family":"Rottman","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Dvorkin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Gold","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2308","reference":[{"key":"e_1_3_1_2_1","unstructured":"1.
