Should I have ACL reconstruction surgery?
This means that ACL rehabilitation must include variable training parameters, which range from an endurance program of low load/high repetitions to a strength oriented phase of high load/low repetitions to focus on these deficits. Depending on the graft type used for ACLR (patellar tendon vs. semitendonosis/gracilis), specific strength deficits
How long does allograft ACL surgery take to heal?
ACL Reconstruction (Patellar Tendon Graft Technique) This procedure repairs your knee after a tear of the anterior cruciate ligament (commonly called the "ACL"). This ligament is in the center of the knee. It helps anchor the femur to the tibia. This …

Results. In 70 percent of the cases, the healing process was completed after 6 months and the remaining 30 percent recovered after 12 months.
How long does it take for a graft to heal ACL?
Within the first few weeks after surgery, you should strive to regain a range of motion equal to that of your opposite knee. Recovery generally takes about nine months. It may take eight to 12 months or more before athletes can return to their sports.Mar 6, 2021
How strong is patellar tendon graft?
The initial graft tensile strength of bone-patellar tendon-bone autograft is 2977 N with a stiffness of 620 N/mm. This is over 1.5 times the strength and 4 times the stiffness of the native ACL. Additionally, graft fixation should be secure enough to allow early rehabilitation with rapid incorporation of the graft.Oct 7, 2020
Does patellar tendon grow back after ACL surgery?
When the ACL tears, it separates and the frayed ends do not touch. Since the ends do not touch, they cannot grow back together.
How do you strengthen ACL graft?

How strong is the new ACL graft?
The bone portion of the graft allows it to incorporate and heal very quickly into the tunnels used for the reconstruction. It is quite strong. Biomechanical studies have shown that it is about 70% stronger than a normal ACL at the time of implantation.Nov 3, 2020
How do I strengthen my patellar tendon after ACL surgery?
Therapeutic Exercises: Knee extensions 90°-45°, progress to eccentrics. Advance closed kinetic chain activities (leg press, one-leg mini squats 0-45° of flexion, step-ups begin at 2” progress to 8”, etc.) Progress proprioception activities (slide board, use of ball, racquet with balance activities,etc.)
Which ACL graft is strongest?
The strongest option is the BTB graft. The graft incorporates more solid into the bone due to the bone plugs on either end of the tendon. However, BTB grafts have been known to have the slowest recovery time when it comes to meeting rehab milestones and returning to sport.Jun 2, 2021
What type of ACL graft is best?
The patellar tendon graft (PTG) has always been the gold standard for anterior cruciate ligament (ACL) reconstruction. Yet, most orthopedic surgeons prefer hamstring grafts for younger athletes and cadaver grafts for older patients.
What percentage of ACL grafts fail?
Traumatic failure of ACL reconstructions has been estimated to occur in between 5% and 10% of cases (28).
Can ACL graft stretch?
When there is no medial meniscus, an ACL graft would be at risk for stretching out. Meniscal root tears can also cause an ACL graft to stretch out, and missed, or unrecognized, posterolateral corner or medial collateral ligament (MCL) tears can also cause an ACL graft to stretch out.
How long does it take for an ACL graft to mature?
By 9 months, the graft will look and function like a new ligament and should be strong enough to cope with a full return to sports. Graph showing how the strength of the ACL graft initially drops and then gradually returns to normal as the graft grows a new blood supply and slowly remodels.
What is the procedure to repair a torn ACL?
This key knee ligament is commonly torn during sports activities. The standard operation to fix a torn ACL is with a patellar tendon graft. The surgeon takes out the middle section of the patellar tendon below the kneecap ( patella ).
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. The patellar tendon is a thick and strong band ...
Can a patella fracture?
This can weaken the patella. In rare cases, heavy use of the quadriceps muscle (on the front of the thigh) can cause the patella to fracture. This often requires a second surgery to repair the broken patella.
What is the purpose of a preoperative visit?
One purpose of this preoperative visit is to record a baseline of information. Your therapist will check your current pain levels, your ability to do your activities, and the movement and strength of each knee. A second purpose of the preoperative visit is to prepare you for surgery.
Do you need anesthesia before surgery?
Most surgical procedures require that some type of anesthesia be done before surgery. A very small number of patients have problems with anesthesia. These problems can be reactions to the drugs used, problems related to other medical complications, and problems due to the anesthesia. Be sure to discuss the risks and your concerns with your anesthesiologist.
What is the procedure called when the intercondylar notch is enlarged?
The intercondylar notch (mentioned earlier) is enlarged so that nothing will rub on the graft. This part of the surgery is referred to as a notchplasty.
Can you exercise after ACL surgery?
If you need to stop suddenly, your muscles must react with just the right amount of speed, control, and direction. After ACL surgery, this ability doesn’t come back completely without exercise. Neuromuscular training includes exercises to improve balance, joint control, muscle strength and power, and agility.
What is the procedure to replace a torn ACL?
Anterior cruciate ligament reconstruction patellar tendon is a surgical procedure to replace the torn ACL with part of the patellar tendon taken from your leg. The new ACL is harvested from the patellar tendon that connects the bottom of the kneecap (patella) to the top of the shinbone (tibia). The procedure is performed under general anesthesia.
Which ligaments are responsible for preventing forward movement of the lower leg bone?
The anterior cruciate ligament prevents excessive forward movement of the lower leg bone (tibia) in relation to the thighbone (femur) as well as limits rotational movements of the knee.
Can you move your knees if you tear your cruciate ligament?
A tear of this ligament can make you feel as though your knees will not allow you to move or even hold you up. Anterior cruciate ligament reconstruction is surgery to reconstruct the torn ligament of your knee with a tissue graft.
How long does it take to recover from ACL surgery?
Recovering from an ACL reconstruction surgery is not an easy process. It takes months of dedicated rehab and hard work. As such, it’s critical to ensure you are able to create space in your life to commit to the rehab process.
How long does it take for a knee graft to heal?
Slow progression of exercises and early protective phases allow the body to gradually cement the graft into place. In the first 2-4 weeks, the risk of the graft being pulled out of place is high due to the fact that it has not yet incorporated into the graft site. 9 After about four weeks, the graft is more solidly in place, however, it is remodelling on a cellular level to become more like a ligament. As a result of this, the graft is mechanically at its weakest around 6-12 weeks post-operatively. Coincidentally, people start feeling a lot better around this point and are keen to do a lot more, making this one of the highest risk times for re-rupture. Here, there is a delicate balance between maintaining load in the knee and the muscles but doing so without compromising graft integrity. 10
How to return to sport?
Common return to sport criteria include (but are not limited to): 1 Strength within 10% of other leg. 2 Hop tests within 10% of other leg. 3 Confidence running, jumping, and cutting at full speed (as well as with other sport specific movements). 4 No functional complaints.
What is ACLR surgery?
ACLR involves removing the damaged ACL and replacing it with muscle tendon. Tunnels are made in the shin and thigh bone and the graft is passed through these tunnels to “reconstruct” and secure the ligament in place. The graft is typically made from either hamstring tendon, patellar tendon, or donor tissue (other grafts such as quadriceps tendon are used but less commonly so). While most surgeons will prefer one type of graft over another, there is currently no scientific evidence pointing to one as superior than the others as they all come with their pros and cons.
Can ACL tear cause instability?
An ACL tear can have significant effects on the way your knee moves, with instability typically being the primary problem. ACL reconstruction (ACLR) surgery aims to surgically recreate the anatomical function of the ACL, however there is a growing body of evidence that surgery is not the only option.
Why do surgeons recommend patellar tendon grafts?
One of the biggest advantages is that many physicians and surgeons prefer to recommend the patellar tendon graft, because it is the closest to resembling the torn anterior cruciate ligament (ACL). The length of both the ACL and the patellar tendon are similar.
Is the patellar tendon the same as the ACL?
The length of both the ACL and the patellar tendon are similar. Also, the bone segments on the end of the graft can be placed right on the bone itself, where the ACL is attached to the bone, making it a bone-to-bone healing process…and considered to be one of the strongest healing methods available. Now, of course there are also a couple of ...
Introduction
Anatomy
- What parts of the knee are involved? Ligaments are tough bands of tissue that connect the ends of bones together. 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 tib…
Rationale
- What does the surgeon hope to accomplish? 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. Many surgeons prefer to use the patellar tendon when reconstructing the ACL. The graft is often chosen because it is one of the strongest ACL grafts. It’s easy to get to, holds well in its location…
Preparation
- What do I need to know before surgery? You and your surgeon should make the decision to proceed with surgery together. You need to understand as much about the procedure as possible. If you have concerns or questions, you should talk to your surgeon. Once you decide on surgery, you need to take several steps. Your surgeon may suggest a complete physical examination by …
Surgical Procedure
- What happens during the operation? Most surgeons perform this surgery using an arthroscope, a small fiber-optic TV camera that is used to see and operate inside the joint. Only small incisions are needed during arthroscopyfor this procedure. The operation doesn’t require the surgeon to open the knee joint. Before surgery you will be placed under either general anesthesia or a type o…
Complications
- What problems can happen with this surgery? As with all major surgical procedures, complications can occur. This document doesn’t provide a complete list of the possible complications, but it does highlight some of the most common problems. Some of the most common complications following patellar tendon graft reconstruction of the ACL are 1. anesthe…
After Surgery
- What should I expect after surgery? You may use a continuous passive motion(CPM) machine immediately afterward to help the knee begin moving and to alleviate joint stiffness. The machine straps to the leg and continuously bends and straightens the joint. This continuous motion is thought to reduce stiffness, ease pain, and keep extra scar tissue from forming inside the joint. …
Rehabilitation
- What will my recovery be like? Patients usually take part in formal physical therapy after ACL reconstruction. The first few physical therapy treatments are designed to help control the pain and swelling from the surgery. The goal is to help you regain full knee extension as soon as possible. The physical therapist will choose treatments to get the quadriceps muscles toned an…
