Table 2 Number of patients followed-up and clinical outcomes at each time point

From: Feasibility of T1rho and T2 map magnetic resonance imaging for evaluating graft maturation after anatomic double-bundle anterior cruciate ligament reconstruction

  Postop. 1 year Postop. 2 years Postop. 4 years
Number of patients 20 17 14
KT-values (mm)a 0.8 ± 1.7 (0.7 ± 1.8)b 0.9 ± 1.7 (1.1 ± 1.7) 1.6 ± 2.7
Rate of positive pivot shift test 5/20 5/17 3/14
Lysholm score NDd ND 95.9 ± 6.2a
Tegner activity scale ND ND 6.0 ± 1.1a
Arthroscopic analysis of graft tensionc AMB: taut, 13; mildly lax, 2; lax, 3
PLB: taut, 10; mildly lax, 2; lax, 6
  1. aData are expressed as mean ± standard deviation
  2. bData in parenthesis indicates means ± standard deviation of 14 patients who were followed up until 4 years postoperatively
  3. cSecond-look arthroscopy was performed at 18.9 months on average. Graft tension relative to normal ACL was categorized as taut, mildly lax, or lax, and results of AMB and PLB are expressed separately
  4. dND not determined
