Abstract: ACL is important for maintenance of knee movement. ACL do not heal itself because of its intrinsically poor healing potential and surgery required. Autografts like quadriceps, hamstrings, patellar tendon and allografts of achilles, tibialis anterior and Hamstrings tendon are used. Anatomic placement of ACL tunnels in its native footprint to better restore knee kinematics conventional transtibial reconstruction or its modifications were compared with the anatomic single bundle ACL reconstruction. Reconstruction with single bundle bone-tendon-bone autograft with interference screw fixation.
Methods: Study includes 100 patients undergoing arthroscopic Single Bundle ACL Reconstruction, Age between 18 to 40 yrs. Demographic, Clinical, radiological data used for functional assessment of arthroscopic anatomical single bundle ACL reconstruction.
Results: Comparable distribution of age between groups based on tear grades which suggests that age is unrelated to tear grades (all p values>0.05). Average preoperative Lysholm knee Score was 75.4± 8.2. Average Lysholm knee Score Before Surgery in grade II tear patient group (78.3 ±8.4) was significantly higher than grade III tear patient group (74.12 ±9.1) (p=0.03) After 3 months of surgery, Lysholm knee score was good (84-90) in majority (62%) of the patients. It was found excellent (91-100) in 24% of the cases. After 3 months of surgery Lysholm knee score was fair (65-83) among 6% patients and was unsatisfactory i.e. (<64) in 8% patients. Average duration of hospital stay was 3.42± 1.02. Average duration of hospital stay in grade II tear patient group was 3.39± 1.was slightly lesser than grade III tear patient group (3.43 ±1.01). However the difference of mean was nonsignificant (p=0.856).
Conclusion: Adequate graft with appropriate thickness is a prerequisite for the success of surgery. Timing of surgery, precision in technique and adequate rehabilitation are the variables which strongly influence the outcome of surgery. Grade of injury does not affect the outcomes.
