The surgical technique seems essential to obtain satisfying outcomes with a low rate of specific complications. Several tip sand tricks can be used to improve this procedure during the revision of total knee arthroplasty (RTKA). <jats:italic>Technique<\/jats:italic>: The osteotomy should be at least: 60\u00a0mm in length and 20\u00a0mm in width to allow fixation with 2 screws; and 10\u201315\u00a0mm thick to resist to screw compression. The proximal cut of the osteotomy must keep a proximal buttress spur of 10\u00a0mm to get primary stability and avoid the tubercle ascension. A smooth end of the TTO distally reduces the risk of a tibial shaft fracture. The strongest fixation is obtained using two bicortical 4.5\u00a0mm screws slightly ascendant. <jats:italic>Results<\/jats:italic>: From January 2010 to September 2020, 135 patients received an RTKA with concomitant TTO and a mean follow-up of 51\u00a0\u00b1\u00a026 months [24\u2013121]. The osteotomy was healed in 95% of patients (<jats:italic>n<\/jats:italic>\u00a0=\u00a0128) with a mean delay of 3.4\u00a0\u00b1\u00a02.7\u00a0months [1.5\u201324]. However, there are some specific and significant complications related to the TTO. Twenty complications (15%) related to the TTO were recorded, with 8 (6%) requiring surgery. <jats:italic>Conclusion<\/jats:italic>: Tibial tubercle osteotomy in RTKA is an efficient procedure to improve knee exposure. To avoid tibial tubercle fracture or non-union, a rigorous surgical technique is primordial with a sufficient length and thickness of the tibial tubercle, a smooth end, a proximal step, a final good bone contact, and a strong fixation.<\/jats:p>","DOI":"10.1051\/sicotj\/2023016","type":"journal-article","created":{"date-parts":[[2023,6,12]],"date-time":"2023-06-12T08:02:37Z","timestamp":1686556957000},"page":"18","source":"Crossref","is-referenced-by-count":8,"title":["Tibial
