Advantages of hamstring grafts include their high "load to failure" strength, the stiffness of the graft, and the low postoperative morbidity. The natural ACL can withstand a load of up to 2,160 newtons. With a hamstring graft, this number doubles, decreasing the risk of re-injury.
ACL injuries in children are a challenge because children have open growth plates in the bottom of the femur or thigh bone and on the top of the tibia or shin. An ACL reconstruction typically crosses the growth plates, posing a theoretical risk of injury to the growth plate, stunting leg growth, or causing the leg to grow at an unusual angle. [18]
The native ACL of a human has a tensile strength on the order of kilonewtons, [3] and an elongation at failure of approximately 10%. [10] The mechanical properties of the native ACL vary throughout the human population. The strength of a child's ACL tends to be greater than that of an adult. [10]
Adsorption rate and tensile strength: Strength retention for at least 7 days. Maintains strength for 10–14 days [2] 84% at 2 weeks, 23% at 4 weeks [2] 80% at 2 weeks, 44% at 8 weeks. Complete absorption within 200 days [2] Structure: Multifilament: Multifilament: Braided: Monofilament Origin: Bovine serosa surface finish. Made by twisting ...
About six weeks ago, after my weekly pickleball league, I awoke to a stabbing pain in my right heel. I'd had knee pain, a jammed thumb, and other ouchies from my favorite sport, but never this ...
The goals of rehabilitation following an ACL injury are to regain knee strength and motion. If an individual with an ACL injury undergoes surgery, the rehabilitation process will first focus on slowly increasing the range of motion of the joint, then on strengthening the surrounding muscles to protect the new ligament and stabilize the knee.
