Table 4 Postoperative MRI findings and arthroscopic appearance

From: Anatomic single-bundle anterior cruciate ligament reconstruction using a calcium phosphate-hybridized tendon graft: a randomized controlled trial with 2 years of follow-up

  CaP group Conventional group P value
Graft intensity on MRI: low, iso, high
 1 year 20, 17, 0 (n = 37) 16, 21, 1 (n = 38) 0.396
 2 years 16, 6, 1 (n = 23) 19, 2, 0 (n = 21) 0.205
Arthroscopic appearance: A, B, C 25, 12, 3 (n = 40) 22, 9, 4 (n = 35) 0.806
  1. Significant difference between the two groups (P < 0.05)
  2. The CaP group underwent single-bundle anterior cruciate ligament reconstruction with a calcium phosphate-hybridized graft, while the conventional group underwent reconstruction with a conventional tendon graft
  3. The arthroscopic appearance of the synovium coverage of each graft was graded as A (completely covered), B (partially covered), or C (almost uncovered)
