Noulis, the author explained how to evaluate the ACL rupture on the knee near to full extension. Then, try to shift the tibia forward and backward. When only the ACL is transected, this forward movement is seen when the knee is barely flexed, whereas a backward movement is noted when the posterior cruciate ligament is transected.
As seen, due to limited resort to open surgery, the 19 th century ACL rupture treatment modality was generally conservative through several months of immobilization that conducted patients to satisfactory stability in most cases but not to normal function. Hubert Goetjes, in , in a detailed review of ACL lesions, suggested direct repair of both acute and chronic ruptures and was the first to suggest to examine the patient under anesthesia to ascertain the diagnosis.
Trying to improve direct suture results at that times unfortunately not so predictable, Georg Perthes proposed to join the ligament to the bone with a bronze and aluminum wire that was passed from the ligament stump to the outside of the femoral condyle through drill holes. Suture repair has been continued until the 80, supported by results obtained by David McIntosh and John Marshall, but was then abandoned due to better results published on ACL reconstruction techniques developed at that times.
In fact, the beginning of the 20 th century sees the evolution toward ACL reconstruction techniques, transplanting for the first times fascia lata and subsequently hamstring and patellar grafts.
In , Fritz Lange presented the results of four cases in which he used an artificial ligament made by woven silk support that he connected to the tendon of the semitendinosus and semimembranosus, to create a ligament substitute.
The incision extended laterally so as to allow the removal of a strip of iliotibial band. Putti described two operations performed on a patient who had ankylosis of the knee following a war wound: In the first surgery, knee arthroplasty was performed with interposition of the fascia lata; in the second, performed for the serious residual instability, the reconstruction of the collateral ligaments and of the ACL with flaps of the fascia lata was carried out.
In the Italian surgeon Riccardo Galeazzi, pioneer of ACL reconstruction with hamstrings, described the use of the semitendinosus tendon, released from its musculotendinous junction, brought intra-articularly through a 5mm tibial tunnel drilled in the tibial epiphysis and a tunnel drilled through the lateral femoral condyle, where it was fixed to the periosteum. Galeazzi used three incisions: One for harvesting of the semitendinosus tendon, another for arthrotomy, and a third laterally for fixation.
He used a cast for 4 weeks and partially weight bearing for 6 weeks. He reported on three cases. One operated in had a follow-up of 18 months, and the final outcome was a stable knee with full extension and only a mild reduction of flexion. Galeazzi was the first that ever published the usage of hamstrings tendon autograft in ACL reconstruction.
Max Lange and Kenneth Cho added further modifications to the technique. In Willis C. Following the operation, a period of immobilization of the limb was foreseen, which was subjected to splinting for 3 weeks.
Of them, nine had an excellent result and were able to return to playing football 6—10 weeks after the surgery. Campbell deduced that among athletes there was the primary need to provide for an immediate reconstruction of the injured ligament and that the procedure used had to be completed quickly avoiding counterproductive intra- or extra-articular reactions.
The first decades of saw the launch of new ideas, but it has been only since the 60 that the treatment of ACL ruptures gained great evolution. Many of these procedures represent the referral of the autologous grafts in use today for ACL reconstruction.
In Kenneth G. A technique using the central one-third of the patellar ligament. In McIntosh [ 26 ] and in Torg et al. Late 70 and 80 viewed a renewed interest on ACL conventional reconstruction procedures. The problems encountered with BPTB technique — bone block passage, patella fractures, and anterior knee pain — has led, in last decades, to new popularity on the hamstring technique initially introduced by Galeazzi and furtherly modified from Cho in [ 31 ] and from Perugia and Puddu, [ 32 ] who developed a more medial positioning of the extra-articular tibial tunnel in a manner to preserve the internal rotational action of the semitendinosus and detached hamstrings tendons distally from the tibia, reinforcing them with a PDS tape.
Lipscomb, from Nashville, published the technique that used both semitendinosus and gracilis tendons in In , M. Friedman first experimented with an arthroscopically assisted self-grafting technique that used four ligament strands. The 70 and 80 have also to be remembered for the development, parallel to conventional autograft procedures, of the augmentation and arthroscopic procedures and the use of allografts.
David J. Dandy from Cambridge has to be reminded as the first to execute an arthroscopic reconstructive procedure and implanting a carbon fiber ligament in combined with a lateral plasty with McIntosh technique. Just as the carbon fibers were set aside, Dacron and Gore- Tex soon become common in reconstructive surgery, also affirmed thanks to the new arthroscopic technique that could enhance the use of synthetic materials to reconstruct the ACL quickly, with minimal trauma and effectively.
However, toward the end of the 80, there was an unacceptable synovitis rate with consequent rupture of the new ligaments that forced the orthopedic community to abandon this reconstructive line.
From the 80 allografts implantation became, after successful use in animals, a positive option which based on their functioning on acting as a collagenous scaffolding for revascularization and fibrovascular creeping substitution.
Shino et al. From the 90, especially in US, allografts grow in interest and showed good results. Actually autografts are still considered more cost-effective and should represent the first choice in ACL reconstruction.
During these past 20 years and the previous decade most surgeons have remained faithful to the concept of self- grafting with the difference that compared to the past these procedures could now be practiced in arthroscopy, minimizing surgical invasiveness and adopting new, stronger, and safer fixation devices.
There were obviously several reasons that led to an increase in the success rate: Rapid diagnosis and early treatment, factors that prevented the occurrence of associated meniscal and cartilaginous injuries which, often led to complications, worsening of results and development of early osteoarthritis.
As said, conventional reconstructions using BPTB or hamstring autografts are the most popular today, along with the use of quadriceps tendon and allografts.
They offer good results also in the long-term follow-up. With this goal, scientists developed more anatomical reconstruction procedures of the ACL creating the two bundles techniques, originally firstly introduced by Key and Weinstein, in these authors took a graft from the semitendinosus and the rectus internus, they rotated these tendons, passed them through a single common tibial tunnel and two separate femoral tunnels and finally they fixed the two tendons used for the reconstruction one against the other at their exit.
More recently, the problems arisen with double-bundle technique have decreased its interest and usage. A recent confirmation comes from last year meta-analysis conducted including five RCTs involving patients that showed no statistically significant difference between single bundle and double bundle reconstructions.
Authors concluded that double bundle ACL reconstruction requires longer operation time, expenditure of double fixation materials, and technical difficulty in revision. Furthermore, the DB techniques require excellent surgical skills and a longer learning curve.
Given that the SB techniques yield similar efficacy with DB techniques in long-term follow-up and are more cost- effective, the SB techniques may be more suitable as the standard techniques of ACL reconstruction. In the past 5 years, due to more precise imaging diagnosis, more advanced arthroscopic techniques and improved physiology comprehension, new primary augmented repair techniques have been developed, including Internal Brace Ligament Augmentation IBLA and Dynamic Intraligamentary Stabilization DIS procedures.
Studies have demonstrated improved stability and graft protection because IBLA works as a load-sharing device, still allowing the graft to see enough stress to undergo ligamentization. In clinical studies, patients gain near-normal knee function, excellent satisfaction, and return to the previous levels of competition activity in the majority of cases.
The BEAR procedure has recently been demonstrated to give results similar to ACLR with hamstring autografts in the first in-human study and PROMS not inferior to autografts at 2 years follow-up in a prospective multicenter randomized study.
PRP augmentation has given variable results. It should favor graft maturation, but this is not still finally proven, certainly also due to its great differences in harvest, preparation, and location of injection and to variable patient biology. Figueroa et al. At 2 years follow-up they found a tendency to faster graft maturation but not in tunnel healing. Gobbi et al. Moreover, in a second study, they evaluated also the adjunct of PRP glue injection at repair site. Usually, the knee joint swells within a short time following the injury.
This is due to bleeding into the knee joint from torn blood vessels in the damaged ligament. The instability caused by the torn ligament leads to a feeling of insecurity and giving way of the knee, especially when trying to change direction on the knee. The knee may feel like it wants to slip backwards. Walking downhill or on ice is especially difficult.
And you may have trouble coming to a quick stop. The pain and swelling from the initial injury will usually be gone after two to four weeks, but the knee may still feel unstable. The symptom of instability and the inability to trust the knee for support are what require treatment.
Also important in the decision about treatment is the growing realization by orthopedic surgeons that long-term instability leads to early arthritis of the knee. When you visit Advantage Physiotherapy, our physiotherapist will first take a history and do a physical exam. The history and physical examination are probably the most important ways to diagnose a ruptured or deficient ACL. In the acute sudden injury, the swelling is a good indicator. A good rule of thumb that orthopedic surgeons use is that any tense swelling that occurs within two hours of a knee injury usually represents blood in the joint, or a hemarthrosis.
If the swelling occurs the next day, the fluid is probably from the inflammatory response. During the physical examination, special stress tests are performed on the knee. Three of the most commonly used tests are the Lachman test, the pivot-shift test, and the anterior drawer test.
Our physiotherapist will place your knee and leg in various positions and then apply a load or force to the joint. Any excess motion or unexpected movement of the tibia relative to the femur may be a sign of ligament damage and insufficiency.
Another way to check for anterior tibial translation is with the KT and KT arthrometers. The arthrometer is placed against the knee to be tested and strapped to the lower leg.
Usually, the normal knee is tested first. The arthrometer applies an anterior force of 15 pounds against the tibia. The amount of anterior tibial translation is measured. The test is repeated with a force of 20 pounds. A third test applies a manual maximal force to the posterior back of the tibia. This is similar to the Lachman test. The results of these tests will help our physiotherapist determine how badly the ACL was injured. We may also combine other tests with tests of ACL integrity to determine whether other knee ligaments, joint capsule, or joint cartilage have also been injured.
Some patients may be referred to a doctor for further diagnosis. Once your diagnostic examination is complete, the physiotherapists at Advantage Physiotherapy have treatment options that will help speed your recovery, so that you can more quickly return to your active lifestyle. When you begin your Advantage Physiotherapy program, our initial treatments for an ACL injury will focus on decreasing pain and swelling in the knee.
We may recommend rest and mild pain medications, such as acetaminophen Tylenol , to help decrease your symptoms. You may need to use crutches until you can walk without a limp. Most of our ACL reconstruction patients are instructed to put a normal amount of weight down while walking. Our physiotherapist will treat swelling and pain with the use of ice, electrical stimulation, and rest periods with your leg supported in elevation. Our physiotherapist may apply treatments such as electrical stimulation and ice to reduce pain and swelling.
We then gradualy add exercises to improve knee range of motion and strength to help you regain normal movement of joints and muscles. Our physiotherapist will have you begin range-of-motion exercises right away, with the goal of helping you swiftly regain full movement in your knee. This may include the use of a stationary bike, gentle stretching, and careful pressure applied to the knee by the physiotherapist.
We will also give you exercises to improve the strength of your hamstring and quadriceps muscles. As your symptoms ease and strength improves, we will guide you in specialized exercises to improve knee stability. Our physiotherapist may suggest use of an ACL brace. This type of brace is usually custom-made and not the type you can buy at the drugstore.
It is designed to improve knee stability when the ACL doesn't function properly. We often recommend an ACL brace when the knee is unstable and surgery is not planned.
As mentioned, a torn ACL that isn't corrected often leads to early knee arthritis. Today, improved education, training, and the management of knee ligament injuries at the high school and college levels have had a profound impact on the National Football League as well.
For the tens of thousands of people in the United States this year who may tear their ACL, the prognosis is positive. Once a debilitating, possibly career-ending injury for an athlete, an ACL injury today is a manageable condition that does not have to mean the end of a healthy, active lifestyle.
Every day, physicians and researchers at institutions like Hospital for Special Surgery are identifying even more effective treatments and developing new therapies for people with ACL injuries.

A benefit of using cadaver tissue is that there is no morbidity from harvesting material from the patient undergoing surgery, meaning that there is no pain or potential adverse consequence as a result of obtaining the graft.
A potential problem is the sterilization treatment can weaken the tissue. This was especially an issue with previous methods. Also, obtaining the tissue and processing it significantly adds to the expense of the procedure. A major downside is that an allograft has a higher failure rate than either a hamstring or patellar tendon. Patellar tendon grafts have been used extensively for many years.
It is attached to the bone on each end, and it is harvested by using a saw to remove a plug of bone on each side along with a portion of the tendon. Usually, the central one-third of the patellar tendon is used, which is about 10 millimeters wide or about half an inch.
The plug of bone on each end of the graft allows it to be very solidly fixed with screws when reconstructing the ACL. 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. Some studies on patellar tendon grafts have demonstrated higher functional scores postoperatively and lower failure rates. The biggest concern is a higher incidence of pain in the front of the knee at the graft harvest site.
This can be bothersome getting back to sports, running and stairs. Patients can also complain of pain when kneeling that may never completely resolve with time. This tends to become less bothersome over time, however. Use of patellar tendon grafts may also cause a higher rate of scarring in the front of the knee, which can lead some patients to experience difficulty achieving full extension after surgery using this graft compared to others.
