What is the ACL graft used for?
Following hamstring graft surgery there is an increased risk of hamstring strain. For this reason, resisted hamstring curl should be held until 4-6 weeks post-op, and close attention should be paid to hamstring related symptoms through out the rehab process. Gaining full knee extension early in the rehab process is crucial to prevent

Do and don'ts after ACL reconstruction?
Don't work your quadriceps early on because this can stretch the ACL graft. Stationery bike riding or lightweight leg presses are recommended during the first three months after surgery. These exercises strengthen the quadriceps while using the hamstrings to protect the ACL graft. Don't swim or run for five months.
How do you rehab a hamstring after ACL surgery?
It should include both short and long muscle length exercises, a mixed approach of hip extension and knee flexion, a specific focus on eccentric strength at long muscle lengths, and high-speed running.
When is ACL hamstring graft weakest?
The graft is at its weakest at 3 to 6 months – just when the patient is beginning to regain confidence. It is therefore essential that return to proper sport is delayed until 9 months post-op.
How strong is hamstring graft for ACL?
Since it has four tendon strands, the graft is very strong, up to two or three times the native ACL. Hamstring grafts have been associated with better extension, lower incidence of post-surgical arthritis and better extension strength.Nov 3, 2020

What happens to hamstring after ACL graft?
So, to answer the question: What Happens to My Harvested Hamstring Tendon After ACL Surgery? The answer is in 70% of the patients, the hamstring tendon will regenerate and this occurs within a year after surgery.May 19, 2016
What happens to hamstring after ACL surgery?
The hamstring tendons in most cases do regenerate. Across the studies, the rate of regeneration varied between 50% to 100% for the semitendinosus tendon, and 46% to 100% for gracilis. The pooled, mean rate of regeneration after 1 year post ACL reconstruction was 79% for semitendinosus and 72% for gracilis.Oct 29, 2015
Does hamstring graft grow back?
Hamstring tendon grafts are not as strong as patellar tendon grafts. Once the hamstring tendons are taken for the graft, they do not grow back and therefore, leave the hamstring weaker than it was before surgery.
What is the best way to recover from ACL surgery?
Prior rehabilitation is essential for improved outcomes following Anterior Cruciate Ligament (ACL) Reconstruction surgery. Your knee incurs deficits in terms of strength, proprioception (the ability to maintain balance), muscle timing and gait (walking patterns) after suffering an ACL injury. Physiotherapy prior to undergoing ACL reconstructive surgery has been shown to be effective in improving strength and balance which may reduce the episodes of ‘giving way’ and decrease the chances of re-injury in an ACL deficient knee. The goals of pre-operative rehabilitation include restoring full range of motion, achieve adequate neuro-muscular control, strengthening muscles that are important in post-operative rehabilitation and achieving an understanding of exercises to be performed after surgery. These factors greatly influence the chances of successful surgery.
What is the impact of ACL reconstruction surgery?
This leads to altered gait mechanics with reductions in stride length, altered swing and stance phases together with weak/uncoordinated firing of hip, knee and ankle musculature. Early weight bearing attempts to restore gait mechanics in a timely fashion and reduce the incidence of anterior knee pain.
What type of fibres are in the ACL?
Muscle contains Type 1 (endurance) and Type 2 (fast-twitch) fibre s in varying amounts. Following ACL injury, these fibres show signs of atrophy (wasting away) and changes in cellular composition. Therefore, ACL rehabilitation requires focus on both these different types of fibres namely; low-load/high repetitions (endurance) and high-load/low repetitions (strength)
What is the role of a surgeon and physiotherapist in rehabilitation?
The surgeon and physiotherapists will guide you through a comprehensive rehabilitation programme to optimize recovery following surgery and facilitate return to sport/activities. General aspects of the post-operative rehabilitation and goals are listed below:
Is squatting an open chain exercise?
This depends on whether the end of the limb is grounded/supported (closed) or unsupported (open). Squatting is an example of a closed-chain activity while knee extensions while sitting would constitute an open-chain exercise for the quadriceps muscle. OKC was initially thought to detrimentally increase anterior tibial translation (shin bone moving forward) following ACL reconstruction and these types of exercises were barred up to a year post-operatively. Current research however shows that controlled OKC does not lead to excessive laxity post-operatively and newer programmes incorporate both types of exercises (ensuring appropriate timing and range when initially commencing OKCs).
Where is the hamstring muscle located in ACL reconstruction?
The graft used in ACL reconstruction is taken from the hamstring tendon (semitendinosus) along the inside part of the thigh and knee.
What is the drawback of a hamstring tendon graft?
A potential drawback of taking out a piece of the hamstring tendon is a loss of hamstring muscle strength. The main function of the hamstrings is to bend the knee (knee flexion). This motion may be slightly weaker in people who have had a hamstring tendon graft to reconstruct a torn ACL.
What is the purpose of ACL surgery?
The main goal of ACL surgery is to keep the tibia from moving too far forward under the femur bone and to get the knee functioning normally again. There are two grafts commonly used to repair a torn ACL. One is a strip of the patellar tendon below the kneecap. The other is the hamstring tendon graft.
How many strips of tendons are there in a knee graft?
The tendons are arranged into three or four strips, which increases the strength of the graft. The surgeon stiches the strips together to hold them in place. Next, the surgeon prepares the knee to place the graft. The remnants of the original ligament are removed.
What is the function of the hamstrings?
The hamstrings function by pulling the leg backward and by propelling the body forward while walking or running. This movement is called hip extension. The hamstrings also bend the knees, a motion called knee flexion.
Where is the ACL located?
The ACL is located in the center of the knee joint where it runs from the backside of the femur (thighbone) to the front of the tibia (shinbone). The ACL runs through a special notch in the femur called the intercondylar notch and attaches to a special area of the tibia called the tibial spine.
How to replace ACL?
Introduction. When the anterior cruciate ligament (ACL) in the knee is torn or injured, surgery may be needed to replace it. There are many different ways to do this operation. One is to take a piece of the hamstring tendon from behind the knee and use it in place of the torn ligament. When arranged into three or four strips, ...
What exercises should be done to strengthen the hamstrings?
It should include both short and long muscle length exercises, a mixed approach of hip extension and knee flexion, a specific focus on eccentric strength at long muscle lengths, and high-speed running.
Which exercise is the most effective for hamstrings?
Sprinting is arguably the most effective hamstring exercise there is, as it incorporates rapid angular velocities and high demands of both hip extension and knee flexion and has the greatest carryover to sport performance for field athletes. Here’s what this review looks like.
What exercises are good for hip hinge?
Longer muscle length exercises that incorporate hip hinge patterns train the proximal hamstring fibers to a greater degree, such as the Romanian deadlift, 45-degree back extension, and kettlebell swing.
