Secondary osteoarthritis at the knee occurs due to loss of mechanical alignment of the limb. At surgery for total knee arthroplasty, mechanical alignment can be restored intra-articularly with appropriate bone cuts and soft tissue balancing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>PRESENTATION OF CASE:<\/jats:title>\n                    <jats:p>We describe 2 case studies with extra-articular tibial deformities (9\u00b0 and 24\u00b0 varus deformity) which were corrected with a 1 stage procedure of total knee arthroplasty with intra-articular deformity correction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>DISCUSSION:<\/jats:title>\n                    <jats:p>Patient selection, pre-operative considerations and surgical technique are discussed with reference to the literature.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>One stage intra-articular correction of extra-articular deformity is suitable for mild degrees of varus deformities (&lt;30\u00b0).

Consideration should be given to the use of computer navigation when conventional jigs cannot be applied to deformed bone.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2012.12.001","type":"journal-article","created":{"date-parts":[[2012,12,21]],"date-time":"2012-12-21T22:19:07Z","timestamp":1356128347000},"page":"276-278","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":6,"title":["Intra-articular correction of extra-articular tibial deformities with total knee arthroplasty"],"prefix":"10.1097","volume":"4","author":[{"given":"W.","family":"Chua","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"R3-12-20260114","doi-asserted-by":"crossref","first-page":"1769","DOI":"10.2106\/00004623-200210000-00005","article-title":"Total knee arthroplasty for arthritis of the knee with extra-articular deformity","volume":"84-A","author":"Wang","year":"2002","journal-title":"Journal of Bone and Joint Surgery"},{"key":"R4-12-20260114","doi-asserted-by":"crossref","first-page":"284","DOI":"10.1016\/j.arth.2005.07.013","article-title":"Total knee arthroplasty using computer-assisted navigation in patients with deformities of the femur and tibia","volume":"21","author":"Klein","year":"2006","journal-title":"Journal of Arthroplasty"},{"key":"R5-12-20260114","doi-asserted-by":"crossref","first-page":"342","DOI":"10.2106\/00004623-200003000-00005","article-title":"Simultaneous femoral osteotomy and total knee arthroplasty for treatment of osteoarthritis associated with severe extra-articular deformity","volume":"82","author":"Lonner","year":"2000","journal-title":"Journal of Bone and Joint Surgery"}],"container-title":["International Journal of Surgery Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S2210261212002374?httpAccept=text\/xml","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S2210261212002374?httpAccept=text\/plain","content-type":"text\/plain","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.lww.com\/01612930-201304030-00012","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,14]],"date-time":"2026-01-14T13:13:19Z","timestamp":1768396399000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.lww.com\/01612930-201304030-00012"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,1]]},"references-count":3,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2013]]}},"URL":"https:\/\/doi.org\/10.1016\/j.ijscr.2012.12.001","relation":{},"ISSN":["2210-2612"],"issn-type":[{"value":"2210-2612","type":"print"}],"subject":[],"published":{"date-parts":[[2013,1]]}}}
