Current treatment options include a 2-staged procedure in which an extra-articular correctional osteotomy is performed several months before the primary TKR, a 1-stage procedure in which an extra-articular correctional osteotomy is performed at the time of the index TKR, or a 1-stage procedure in which TKR is performed with correction of the extra-articular deformity.<\/jats:p>\n          <jats:p>One-stage TKR with intra-articular correction of the extra-articular deformity is our treatment of choice. With proper planning, appropriate bone cuts to restore alignment, and the necessary soft tissue releases to balance the knee in flexion and extension, a satisfactory TKR can be achieved.<\/jats:p>\n          <jats:p>Two patients with arthritis and a severe extra-articular deformity (varus\/valgus deformity &gt;20\u00b0, recurvatum and malunion of a tibial or femoral fracture) were treated with 1-stage TKR with intra-articular correction of the extra-articular deformity. The technique followed had been successfully performed in 15 previous cases. The procedure was clinically successful in both patients without complications. At 2-year follow-up, Knee Society Scores improved from 40 to 95 and there was no evidence of instability in either case.<\/jats:p>","DOI":"10.3928\/01477447-20090728-22","type":"journal-article","created":{"date-parts":[[2009,9,15]],"date-time":"2009-09-15T16:40:09Z","timestamp":1253032809000},"page":"676-678","source":"Crossref","is-referenced-by-count":27,"title":["Extra-articular Deformity Is Always Correctable Intra-articularly: In the Affirmative"],"prefix":"10.3928","volume":"32","author":[{"given":"Jonathan H.","family":"Koenig","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aditya V.","family":"Maheshwari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amar S.","family":"Ranawat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chitranjan S.","family":"Ranawat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2308","reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200307000-00056"},{"issue":"21","key":"e_1_3_1_3_2","first-page":"59","article-title":"Total knee arthroplasty in patients with associated extra-articular angular deformity","author":"Mann JW","year":"1997","unstructured":"Mann JWIII, Insall JN, Scuderi GR.
