Forty\u2010one knees underwent BKA combined medial and patellofemoral replacement (BKA\u2010MP) and 18\u00a0knees underwent BKA combined lateral with patellofemoral replacement (BKA\u2010LP). Survival rates, the modified Cincinnati Knee Rating Scale, WOMAC, VAS, SF\u201036, a satisfaction survey, and radiographic evaluation were used to evaluate outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Overall, survival rates were 98% and 92% at 2 and 5 years, respectively. Of 56\u00a0knees (95%) that did not fail, all patient\u2010reported functional scores significantly improved post\u2010operatively (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.01), regardless of the previous surgeries, with a high level of satisfaction (51\/56\u00a0knees, 91%). Radiographically, all the femoral components fit perfectly and 56\u00a0knees (95%) of the tibial components fit with less than 2\u00a0mm of undercoverage or overhang. Three knees (5%) required the conversion to TKA and 17\u00a0knees (29%) required subsequent surgical procedures, of which multiply operated knees had higher rate than virgin knee [14\/40 (35%) vs. 3\/16 (19%)].\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>CIM\u2010BKA allowed precise fit of the components and provided a significant improvement post\u2010operatively with a high level of satisfaction over short\u2010 to mid\u2010term follow\u2010up. This novel CIM\u2010BKA is resurfacing, and does not require 10\u2010mm faceted cuts, being only 3\u2010mm\u2010thick, which preserves bone stock for the future. It may be a promising option for relatively young active patients with bicompartmental osteoarthritis with a longer term follow\u2010up being necessary.<\/jats:p>\n                  <\/jats:sec>\n
