Introduction. The anterior cruciate ligament (ACL) is an important stabilizing ligament of the knee that is frequently injured by athletes and trauma victims. There are between 100,000 and 200,000 ACL ruptures per year in the United States alone (1,2). Patients with ACL tear are told to expect a return to full activity and sports between 8 and 12 months following surgery, depending upon their baseline function, sport, and compliance with a rehabilitation program (3). In some cases, 18 months or longer may be required for a graft to be fully incorporated, and rehabilitation of the affected extremity to be completed (3). Novel approaches to anterior cruciate ligament (ACL) rehabilitation develop continually (3). ACLR autograft laxity and knee stability are two parameters that influence rehabilitation strategy and return to previous physical activity. During this study we were interested in autograft diameter inpact on two previously mentioned characteristics. Research aim. To determine impact of autograft diameter on reconstructed ACL laxity and functional stability. We hypothesized that thicker autograft will lead to faster ACLR function recovery and lower risk of functional instability. Research methods and organization. All subjects (N=46) had ACL reconstruction with autograft formed out of t.m. semitendinosus and t.m. gracilis. They were divided into 2 groups: group A (N=27) patients, who had visits at sports medicine doctor 3 and 6 months after ACL reconstruction and group B (N=19) respectively 6 and 12 months after ACL reconstruction. All patients were tested by GenourobTM arthrometer at each visit for ACLR function evaluation. We evaluated targeted and opposite knees ACL laxity S (mm), difference between knees in laxity (D) and functional knee instability risk (Slope P2). Then ΔD and ΔSlope P2 values were found, these values describe the change of D and Slope P2 during certain period. Statistical analys[...].
