Many designs were introduced to increase the stability of the tibial tray, hence the longevity of the prosthesis. This retrospective study was performed on 168 patients who received NexGen cemented primary total knee either with standard tibial tray (group A) or tibial tray with an intramedullary stem (group B) between May 2008 and May 2017. We reviewed all preoperative and postoperative clinical and radiological data retrospectively. In addition, a prospective clinical and radiological reassessment was done. Our aim was to answer the following questions: (1) Is there any difference between both groups in regard to clinical and radiological results? (2) Is there any difference in the revision rate? (3) Is there a role of using stemmed tibial tray in primary TKR? Better results were recorded in obese and severely obese patients having stemmed cemented tibial tray and so for patients with marked and severe preoperative varus angle. Our recommendations are to use cemented tibial tray with a stem in complicated primary surgery without fear of adverse effects on short and intermediate terms of follow-up.<\/jats:p>","DOI":"10.1055\/s-0040-1712085","type":"journal-article","created":{"date-parts":[[2020,5,22]],"date-time":"2020-05-22T22:33:31Z","timestamp":1590186811000},"page":"015-020","source":"Crossref","is-referenced-by-count":7,"title":["Tibial Tray with a Stem: Does It Have Any Role in Primary Cemented Total Knee Replacement?"],"prefix":"10.1055","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5015-3625","authenticated-orcid":false,"given":"Ahmed M.","family":"Samy","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Traumatology, Faculty of Medicine, Tanta University, Tanta, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wael","family":"Azzam","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Traumatology, Faculty of Medicine, Tanta University, Tanta, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2020,5,22]]},"reference":[{"issue":"03","key":"ref1","doi-asserted-by":"crossref","first-page":"492","DOI":"10.1016\/j.arth.2010.01.107","article-title":"Cementing the tibial component in total knee arthroplasty: which technique is the best?","volume":"26","author":"J Vanlommel","year":"2011","journal-title":"J Arthroplasty"},{"issue":"06","key":"ref2","doi-asserted-by":"crossref","first-page":"744","DOI":"10.1054\/arth.2000.6617","article-title":"The effect of the preoperative bone quality on the fixation of the tibial component in total knee arthroplasty","volume":"15","author":"M G Li","year":"2000","journal-title":"J Arthroplasty"},{"issue":"01","key":"ref3","doi-asserted-by":"crossref","first-page":"185","DOI":"10.1007\/s11999-014-3529-6","article-title":"A 30-mm cemented stem extension provides adequate fixation of the tibial component in revision knee arthroplasty","volume":"473","author":"P F Lachiewicz","year":"2015","journal-title":"Clin Orthop Relat Res"},{"issue":"11","key":"ref4","doi-asserted-by":"crossref","first-page":"2639","DOI":"10.1007\/s11999-008-0424-z","article-title":"Stemmed implants improve stability in augmented constrained condylar knees","volume":"466","author":"J J Rawlinson","year":"2008","journal-title":"Clin Orthop Relat Res"},{"issue":"04","key":"ref5","doi-asserted-by":"crossref","first-page":"483","DOI":"10.1016\/j.clinbiomech.2007.11.012","article-title":"Addition of a short central extension to surface cemented tibial trays in primary TKA: an in vitro study of the effect on initial fixation stability and its relationship to supporting bone density","volume":"23","author":"A P\u00e9rez-Blanca","year":"2008","journal-title":"Clin Biomech (Bristol, Avon)"},{"issue":"248","key":"ref6","first-page":"13","article-title":"Rationale of the Knee Society clinical rating system","author":"J N Insall","year":"1989","journal-title":"Clin Orthop Relat Res"},{"issue":"01","key":"ref7","doi-asserted-by":"crossref","first-page":"71","DOI":"10.1097\/00004424-199101000-00013","article-title":"A standardized technique for lower limb radiography.
