This article is retrospective consecutive series of 110 valgus knees using CR implants with a minimum 2-year follow-up. Deformity correction was achieved using stepwise sequential soft tissue releases (iliotibial band, popliteus tendon, lateral collateral release through sliver femoral condylar osteotomy). Demographic data, range of movement, and degrees of deformity were collected. The Oxford Knee Score (OKS) was used as patients' reported outcome measure at final follow-up. One-hundred and four patients (110 knees) were included (87 females\/17 males) with mean age of 68.7 years. Primary diagnosis was osteoarthritis in 85 patients and rheumatoid arthritis in 19 patients. Mean follow-up was 5.5 years (median: 5 years; range: 2\u201314 years). Preoperative valgus deformity was measured radiographically using the mechanical tibiofemoral angle with a mean 18.6\u00b0 (standard deviation [SD]: 7.5; range: 11\u201338\u00b0). At final follow-up, mechanical tibiofemoral angle was 3.8\u00b0 (SD: 1.97; range: 2\u20138\u00b0). A p-value was &lt;0.0001 and mean OKS was 42 (SD: 5.4; range: 36\u201348) suggesting satisfactory patients' reported outcomes with no implant revision for any cause. CR implants for valgus knees using staged soft tissue releases including sliver condylar osteotomy had excellent medium-term survivorship and satisfactory patient reported outcome measures. The Level of Evidence for this study is IV.<\/jats:p>","DOI":"10.1055\/s-0039-1696956","type":"journal-article","created":{"date-parts":[[2019,9,18]],"date-time":"2019-09-18T22:47:28Z","timestamp":1568846848000},"page":"422-426","source":"Crossref","is-referenced-by-count":2,"title":["High Medium-Term Survivorship of Cruciate-Retaining Total Knee Arthroplasties (110 Knees) for Valgus Deformity"],"prefix":"10.1055","volume":"34","author":[{"given":"Hosam E.","family":"Matar","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Wrightington Hospital, Wigan, Apley Bridge, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Thangaraj","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Wrightington Hospital, Wigan, Apley Bridge, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akash","family":"Saraogi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Wrightington Hospital, Wigan, Apley Bridge, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Videshnandan","family":"Raut","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Wrightington Hospital, Wigan, Apley Bridge, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2019,9,18]]},"reference":[{"issue":"02","key":"ref1","doi-asserted-by":"crossref","first-page":"126","DOI":"10.2106\/JBJS.K.00607","article-title":"Preoperative malalignment increases risk of failure after total knee arthroplasty","volume":"95","author":"M A Ritter","year":"2013","journal-title":"J Bone Joint Surg Am"},{"issue":"08","key":"ref2","doi-asserted-by":"crossref","first-page":"1131","DOI":"10.1302\/0301-620X.84B8.0841131","article-title":"Lateral femoral sliding osteotomy lateral release in total knee arthroplasty for a fixed valgus deformity","volume":"84","author":"J Brilhault","year":"2002","journal-title":"J Bone Joint Surg Br"},{"issue":"260","key":"ref3","doi-asserted-by":"crossref","first-page":"170","DOI":"10.1097\/00003086-199011000-00028","article-title":"A sequential three-step lateral release for correcting fixed valgus knee deformities during total knee arthroplasty","author":"F F Buechel","year":"1990","journal-title":"Clin Orthop Relat Res"},{"issue":"345","key":"ref4","first-page":"29","article-title":"10- to 20-year followup of total knee arthroplasty for valgus deformities","author":"K C Miyasaka","year":"1997","journal-title":"Clin Orthop Relat Res"},{"key":"ref5","first-page":"271","article-title":"Total knee arthroplasty for severe valgus deformity","volume":"87","author":"A S Ranawat","year":"2005","journal-title":"J Bone Joint Surg Am"},{"issue":"273","key":"ref6","first-page":"5","article-title":"Total knee arthroplasty in valgus knees","author":"S H Stern","year":"1991","journal-title":"Clin Orthop Relat Res"},{"issue":"288","key":"ref7","first-page":"234","article-title":"Correction of ligament and bone defects in total arthroplasty of the severely valgus knee","author":"L A Whiteside","year":"1993","journal-title":"Clin Orthop Relat Res"},{"key":"ref8","doi-asserted-by":"crossref","DOI":"10.1007\/978-3-642-59295-9","volume-title":"Ligament Balancing in Total Knee Arthroplasty","author":"L A Whiteside","year":"2004"},{"issue":"273","key":"ref9","first-page":"9","article-title":"Primary total knee arthroplasty in patients with fixed valgus deformity","author":"K A Krackow","year":"1991","journal-title":"Clin Orthop Relat Res"},{"issue":"12","key":"ref10","doi-asserted-by":"crossref","first-page":"2671","DOI":"10.2106\/00004623-200412000-00013","article-title":"Total knee arthroplasty for severe valgus deformity.
