To improve these outcomes, we have modified the surgical anchor placement and have carried out a thorough follow-up examination.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Materials and methods<\/jats:title>\n                <jats:p>Thirteen older patients (8 female, 5 males) with a median age of 64.2 (range, 52.1\u201380.4) years were surgically treated for acute proximal hamstring rupture using modified anchor placement and participated in a follow-up assessment at a median of 46.2 (11.2\u201375.0) months after surgery. Patients completed the Perth Hamstring Assessment Tool (PHAT), quality of life questionnaire (EQ-5D-5L) and the Lower Extremity Functional Scale (LEFS), and rated their satisfaction level on a scale from 0 to 100%. Local tenderness on the ischial tuberosity and maximum passive hip flexion were measured on both limbs. Maximum isokinetic knee flexor muscle strength was measured bilaterally using a dynamometer.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The median (range) PHAT, EQ-5D-5L and LEFS score were 78.8\/100 (54.6\u201399.8), 0.94\/1 (0.83\u20131) and 88.75\/100 (61.25\u2013100). The median satisfaction was 100% (90\u2013100%). Only one patient felt discomfort when the ischial tuberosity was palpated. Neither maximum passive hip flexion nor maximum isokinetic flexor muscle strength differed between the operated and non-operated side (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.58). Clinical scores did not correlate with the leg symmetry index of knee flexor muscle strength (Spearman\u2019s rho\u2009&lt;\u20090.448, <jats:italic>P<\/jats:italic>\u2009&gt;\u20090.125).
