Pain was evaluated with the numerical rating scale (NRS), and knee flexor\/extensor muscle strength was assessed using a handheld dynamometer. Physical function was evaluated using a timed up and go (TUG) test. The NRS, knee flexor\/extensor muscle strength, and TUG were compared preoperatively and 1\u00a0year postoperatively using the Wilcoxon signed-rank test. The correlation of patient characteristics, NRS score, knee flexor\/extensor muscle strength, and preoperative TUG with the postoperative TUG was analyzed using Spearman\u2019s correlation coefficient.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      NRS (3.5\u2009\u00b1\u20092.1 to 0.1\u2009\u00b1\u20090.5 points), knee flexor strength (111.9\u2009\u00b1\u200950.2 to 146.7\u2009\u00b1\u200951.5 Nm), knee extensor strength (181.9\u2009\u00b1\u200992.8 to 256.9\u2009\u00b1\u2009107.1 Nm), and TUG (12.3\u2009\u00b1\u20095.7 to 9.2\u2009\u00b1\u20092.2\u00a0s) all improved significantly from preoperatively to 1\u00a0year postoperatively (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
