Before March 26, 2019, arthroscopy was performed using a post\u2010based system. After this date, the senior author converted to using a postless system. Intraoperative traction force and fluoroscopic distraction distance were measured to calculate hip stiffness coefficients at holding traction (k\u2010hold) and maximal traction (k\u2010max). We used multivariable regression analysis to determine whether postless arthroscopy was predictive of lower stiffness coefficients when controlling for other relevant patient\u2010specific factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Hip arthroscopy was performed with a post\u2010based system in 105 patients and with a postless system in 51. Mean holding traction force (67.5 \u00b1 14.0 kilograms\u2010force [kgf] vs 55.8 \u00b1 15.3 kgf) and mean maximum traction force (96.0 \u00b1 16.6 kgf vs 69.9 \u00b1 14.1 kgf) were significantly lower in the postless group. On multivariable analysis, postless traction was an independent\u00a0predictor of decreased k\u2010hold (\u03b2\u00a0= \u201331.4; 95% confidence interval, \u201361.2 to \u20131.6) and decreased k\u2010max (\u03b2\u00a0= \u201390.4; 95% confidence interval, \u2013127.8 to \u201353.1). Male sex, Beighton score of 0, and poor hamstring flexibility were also predictors of increased k\u2010hold and k\u2010max in the multivariable model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Postless traction systems decrease the amount of traction force required for adequate hip distraction for both maximal and holding traction forces when compared with post\u2010based systems.
