These defects should be meticulously addressed so as to avoid malalignment and premature loosening and failure. Out of the many options available to deal with these defects, impaction bone grafting provides a more biological solution, which is especially important in case of primary knees.<\/jats:p><jats:p><jats:italic>Materials and methods<\/jats:italic>: A retrospective analysis was done and patients with severe varus deformity of more than 20 degrees who had undergone primary knee arthroplasty with impaction bone grafting of the tibial condyle defect were followed up.<\/jats:p><jats:p><jats:italic>Results<\/jats:italic>: Between 2008 and 2014, out of the 1124 patients who underwent primary total knee arthroplasty, only 26 knees in 23 patients met the inclusion criteria. The amount of varus deformity ranged from 20 to 35 degrees. Follow-up ranged from 3 to 8\u00a0years with an average of 6\u00a0years. The average pre-operative Knee Society Score (KSS) and Western Ontario McMaster Universities (WOMAC) score were 24.2 and 78, respectively. There were significant improvements in the post-op scores, with the average KSS being 90.2 and the WOMAC being 38.<\/jats:p><jats:p><jats:italic>Conclusion<\/jats:italic>: Impaction bone grafting provides an invaluable option to the orthopedic surgeon for managing bone defects, especially in case of primary knee arthroplasty as it reconstitutes the bone stock.<\/jats:p>","DOI":"10.1051\/sicotj\/2018056","type":"journal-article","created":{"date-parts":[[2019,1,14]],"date-time":"2019-01-14T08:58:07Z","timestamp":1547456287000},"page":"2","source":"Crossref","is-referenced-by-count":6,"title":["Mid-term results of impaction bone grafting in tibial bone defects in complex primary knee arthroplasty for severe varus deformity"],"prefix":"10.1051","volume":"5","author":[{"given":"Yashwant Singh","family":"Tanwar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yatinder","family":"Kharbanda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harsh","family":"Bhargava","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kulbhushan","family":"Attri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anoop","family":"Bandil","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"250","published-online":{"date-parts":[[2019,1,14]]},"reference":[{"key":"R1","unstructured":"Insall JN (1993) Revision of aseptic failed total knee arthroplasty.
