Biomechanical Measures during Landing and Postural Stability Predict Second Anterior Cruciate Ligament Injury after Anterior Cruciate Ligament Reconstruction and Return to Sport

Background There is no consensus about whether isolated anterior cruciate ligament reconstruction using multistrand hamstring tendon with nonoperative treatment for chronic medial collateral ligament injury is sufficient. Purpose To assess clinical outcome for patients with chronic anterior cruciate ligament injury and accompanying grade II valgus laxity who received medial hamstring anterior cruciate ligament reconstruction alone. Results were compared with those of patients with isolated chronic anterior cruciate ligament injury without valgus laxity. Study Design Cohort study; Level of evidence, 2. Methods Two hundred eighty-nine patients with isolated anterior cruciate ligament injury were compared with 53 patients with accompanying valgus laxity (minimum follow-up, 24 months). The following parameters were compared between the 2 groups at the last follow-up: range of motion, KT-1000 arthrometer value, pivot-shift test result, Lysholm knee scale, knee extensor muscle strength, return to sporting activities, subjective recovery, and International Knee Documentation Committee grade. Differences in clinical outcome were evaluated between those with preoperative International Knee Documentation Committee grade B and grade C and between those with grade A and grade B or C at final evaluation. Results Postoperative KT-1000 arthrometer value averaged 1.2 mm for those with isolated anterior cruciate ligament injury and 1.6 mm for those with accompanying valgus laxity (not significant, P = .281). There was no significant difference between these 2 groups regarding the other items. In patients with preoperative valgus laxity, KT-1000 arthrometer values at final evaluation between patients with preoperative grade B and C were not significantly different. The value for subjects with grade A at final evaluation was 1.3 mm and for those with grade B or C at final evaluation was 2.7 mm ( P = .065). Conclusion There was no clinically significant difference regarding outcome of anterior cruciate ligament multistrand hamstring reconstruction alone for 90% of patients with grade II valgus laxity who regained medial stability with nonoperative management compared with those who underwent the same anterior cruciate ligament reconstruction for an isolated anterior cruciate ligament tear.

Anterior Cruciate

We examined persons after anterior cruciate ligament injury and for 1.5 years after anterior cruciate ligament reconstruction to analyze changes in anterior knee laxity, lower extremity muscle strength, endurance, and several parameters of neuromuscular function. Sixteen men and nine women (average age, 23.8 years) were evaluated preoperatively, then underwent intraarticular autogenous patellar tendon anterior cruciate ligament reconstruction by the same surgeon and were evaluated at 6, 12, and 18 months postoperatively. Muscle strength was measured isokinetically and neuromuscular function was quantified with simultaneous anterior tibial translation and surface electromyography tests. Forty subjects (26 men and 14 women; average age, 23.5 years) with no known knee abnormalities served as the control group. Subjective questionnaire results showed that by 18 months postoperatively, 20 subjects (80%) believed they had regained their preoperative levels of function. Unfortunately, muscle function in most subjects had not returned to normal. At 12 to 18 months postoperatively, when knee rehabilitation was terminated, significant deficiencies in muscle performance persisted in most patients. Interestingly, in this group of stable knees, quadriceps and hamstring muscle reaction times appeared to be the best objective indicators of subjective knee function.

Anterior Cruciate

Anterior cruciate ligament injury is one of the most common injuries around knee and poses quiet a lot management controversies. Anterior cruciate ligament has a pivot role in function and stability of the knee joint along with all other ligaments, being a prime stabilizer preventing the anterior translation of tibia over femur. Acute anterior cruciate ligament injury causes recurrent episodes of instability, pain and decreased motion. Anterior cruciate ligament reconstruction allows return to pre injury levels even in athletes, delays development of early osteoarthritis and reestablish the stability of the joint. Graft fixation during ACL reconstruction can be achieved with use of either metal screws or bio absorbable screws. Bio absorbable screws usage provide better visibility in postoperative MRI and also avoid removal at later stage. However there are controversies regarding the ideal graft, ideal fixation device, ideal time and technique of reconstruction. In this study we have compared the metal and bio absorbable screw for fixing the graft and reported the result.
