A 2-year follow-up of rehabilitation after ACL reconstruction using patellar tendon or hamstring tendon grafts: a prospective randomised outcome study

摘要: Sixty-eight patients were clinically evaluated preoperatively, 3, 5, 7, 9 months, 1 and 2 years after ACL reconstruction, 34 with patellar tendon graft, hamstring graft. Outcome regarding graft choice anterior knee laxity (P = 0.04) was in favour of Hamstring led to a larger laxity, 2.4 mm compared 1.3 at year 2.5 1.5 mm, respectively, 0.05).
