Revision rate in Uncemented group with intra-operative fracture is 17.7% (P < 0.001)* with Odds ratio = 12.52 (95%CI 4.42-35.30).
90 Day mortality rate in Uncemented group with intra-operative fracture is 19.7% (P < 0.03) * with Odds ratio = 2.16 (95% CI 1.03-4.34)
P < 0.05* significant findings confirm that adverse outcomes are strongly linked to the Uncemented group sustaining intra-operative fracture.
