title: Decreased range of motion following acute versus chronic anterior cruciate ligament reconstruction.
abstract: Eighty patients with acute anterior cruciate ligament (ACL) reconstruction were compared to 80 patients with chronic ACL reconstruction. Before reconstruction, all patients had 0 degrees-120 degrees active motion, performed a straight leg raise without loss of extension, and demonstrated good quadriceps control. At 3 months, 4 acute patients had decreased range of motion (<10 degrees-120 degrees), but none at 6 or 12 months, and did not require repeat surgery. One chronic patient had decreased range of motion at 3 and 6 months and 1 patient had decreased range of motion at 1 year; both patients required operative intervention. Using these specific preoperative criteria, no increased incidence of decreased range of motion was found when an ACL reconstruction was performed within 3 weeks of injury.
