The effect of a trapezoidal flexion gap in a functionally aligned TKA remains unknown. The aim of this study was to investigate the effect of a larger lateral flexion gap in a robotic\u2010assisted (RA), functionally aligned (FA) and\u00a0cruciate\u2010retaining (CR) TKA on clinical outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Data from 527 TKA in 478 patients from 2018 to 2020 were\u00a0collected. All patients underwent an RA (MAKO, Stryker), FA and\u00a0CR TKA. Gap measurements were collected intraoperatively. Patient\u2010reported outcome measures (PROMs), pain Visual analogue score (VAS)\u00a0and range of motion were collected postoperatively. Patients were also asked about the ease of stair ascent and descent and kneeling on a 5\u2010point scale. The minimum follow\u2010up was 2 years. Patients were stratified into three groups based on lateral flexion laxity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      At 2 years postoperatively, the group with a looser gap (3\u20136\u2009mm) had higher mean PROMs when compared with the group with a gap of 2\u20133\u2009mm. There were no differences detected in any other outcomes at 2 years. A total of 70.9% of patients in the group with a 3\u20136\u2009mm gap reported being able to walk down a flight of stairs 'easily', compared with 56.7% in the 2\u20133\u2009mm group and 54% in the
