Knee Joint Ligament Reconstruction: What Is It?
Ligament reconstruction of the knee joint is an advanced surgical procedure to restore the continuity of damaged ligaments and their attachments, usually anterior cruciate ligament (90% cruciate ligament injuries). This type of surgery is crucial for restoring adequate stability to the knee joint and preventing further damage and the development of degenerative changes. This procedure is carried out most often by arthroscopic technique, which minimizes the risk of infection and speeds up the patient's healing process.
Until recently, reconstructive surgery was indicated for patients who were young, athletes or those wishing to return to regular physical activity. Such selective treatment led to secondary damage to the remaining structures of the knee joint. Currently, we now know that even less active, older people are eligible for ligament reconstruction surgery.
If the procedure is delayed, the risk of damage to other structures of the joint is greatly increased, most often the cartilage and meniscus are affected, leading to the acceleration of osteoarthritis, or gonarthrosis. With reconstruction, the anatomical and biomechanical function of the ligament can be restored, which is crucial for the proper functioning of the joint.
Importance of Ligaments in the Knee Joint
Ligaments in the knee joint play a key role in ensuring its stability and proper mobility. The anterior cruciate ligament (ACL) along with the posterior cruciate ligament (PCL) and collateral ligaments (MCL and LCL) form a complex of structures that stabilize the knee. Connecting the femur to the tibia, these ligaments act as stabilizers for movements taking place in the sagittal and frontal planes, as well as limiting rotational movements, which is essential during daily activities and intensive sports.
Flexion and extension movements are secured by the cruciate ligaments, while in the frontal plane the joint is stabilized by the collateral ligaments (MCL and LCL). Without the proper functioning of the ligaments, the knee joint becomes unstable, which can lead to injuries to the other structures of the joint.
When is Reconstruction Indicated?
Reconstruction of the ligaments of the knee joint, especially the anterior cruciate ligament, is recommended in cases of Total or partial rupture, with perceived instability of the knee joint. The need for surgery therefore depends on the degree of damage and the lifestyle of the injured person. There are three degrees of ligamentous damage:
- Grade I light - indicates damage to a small number of fibers, the physiological length of the ligament is increased, but the joint is still stable,
- Grade II - Moderate - indicates that the continuity of the predominant fibers has been interrupted, the remaining preserved part of the ligament has increased in length, leading to its failure,
- Grade III severe - indicates a complete rupture of the continuity of the ligament and detachment of its attachment, the ligament is completely inoperable, there is an increased risk of damage to other structures.
Taking into account the lifestyle of the patient himself, the indication for the procedure may also be the nature of the work performed or the desire to return to sport, requiring high stability of the knee joint, and regularly occurring symptoms that reduce quality of life, such as pain and swelling.
Adequate and accurate diagnosis of the damage to the knee joint allows the earliest possible introduction of a series of procedures necessary to characterize the damage in order to combat the effects of the injury in the best possible way.
If cruciate ligament damage is suspected, an effective diagnostic scheme is based on history, physical examination and imaging. In this case, the most reliable examination will be MRI (MRI). The physical examination consists of Patient observation, palpation and structure-specific clinical diagnostic tests performed by both doctors and physiotherapists.
The risk factors contributing to ligamentous damage are many. Most often, we talk about the multifactorial aspect contributing to the damage, the basis of which may relate to the interaction of neuromuscular, biomechanical, anatomical, geometrical or hormonal factors.
Ignoring such an injury can lead to further damage within the joint. Isolated ligamentous injuries to the cruciate ligaments are rare. Most often, this injury is associated with damage to the collateral ligaments (MCL and LCL) and meniscus (MM and ML) due to their anatomical connections. A completely ruptured ACL ligament, unfortunately, does not exhibit self-healing capabilities.
Reconstructive surgery should be performed approximately 3 weeks after the injury, however, taking into account modern research, this value is not established. It is assumed that the appropriate period for surgery is when the swelling has decreased and the range of mobility of the injured region has been restored.
In order to prevent permanent damage and allow the patient to return to full mobility, it is important to stay in contact with specialists at all times to choose an individualized treatment, whether it be surgery or conservative treatment.
Course of the Anterior Cruciate Ligament Reconstruction Process
Anterior cruciate ligament (ACL) reconstruction is an advanced surgical procedure aimed at restoring stability to the knee joint after it has been damaged. The process begins with patient preparation, through the surgical procedure itself, to full rehabilitation. Using arthroscopic techniques, the procedure is less invasive, shortening recovery time and reducing pain.
The purpose of performing arthroscopic ACL reconstruction surgery is to Stabilization of the knee, prevention of further damage and improvement of the patient's comfort related to regaining the ability to return to full functional capacity. Anterior cruciate ligament reconstruction involves removing the damaged ligament and placing a graft in its place, which can come from the patient (autograft) or from a donor (allograft).
Thus, the general division of anterior cruciate ligament reconstruction procedures is based on the origin of the transplanted graft. We distinguish between:
a) Autologous transplants- performed using tendons from the body of the patient undergoing reconstruction:
- Reconstruction from ST and GR - using the tendons of the semitendinosus (ST, semitendinosus) and gastrocnemius (GR, gracilis) muscles,
- Reconstruction with BTB (bone-tendon-bone) - which uses a fragment of the patellar ligament along with its bony components,
- Reconstruction with mQF - Using 1/3 of the tendon of the quadriceps muscle of the thigh and the bony block of the proximal part of the patella.
(b) Allogeneic transplants - performed using grafts from another organism or artificial materials used to create an artificial implant:
- Internal Bracing - Using synthetic tape as a scaffold for the damaged ligament
- Transplant obtained from a deceased donor - The most commonly harvested tissue is the ligament of the patella and the Achilles tendon,
- LARS synthetic prosthesis - It is constructed of nonabsorbable polyester fibers.
ACL reconstruction procedures are definitely more often performed using autogenous grafts. The lower risk of postoperative complications and the high strength of the grafts, as well as the high quality of the procedures performed using grafts made from the patient's own tissue, makes the frequency of these procedures far higher than that of allogeneic grafts.
The duration of surgery is one to two hours, depending on the extent of the damage. For larger injuries, such as meniscus damage, the surgery time may be longer.

Preparation for Treatment
Preparation for anterior cruciate ligament reconstruction surgery begins na długo przed samą operacją. Ważne jest, aby pacjent był psychicznie gotowy na proces leczenia, co często obejmuje konsultacje z lekarzem ortopedą oraz anestezjologiem. Pacjent powinien być świadomy, że operacja będzie przeprowadzana pod znieczuleniem, ogólnym lub podpajęczynówkowym, w zależności od jego stanu zdrowia i preferencji.
Pre-operative rehabilitation aims to wyciszenie skutków urazu poprzez redukcję symptomów takich jak ból czy obrzęk oraz przywrócenie zakresu ruchu. Zgodnie z badaniami naukowymi pacjenci niepoddawani specjalistycznej rehabilitacji, z uwzględnieniem okresu przygotowawczego przed zabiegiem, charakteryzują się większymi problemami w kontekście czasu w jakim udało im się odzyskać zakres ruchu wyprostnego w operowanym stawie. Zauważono również, że pod względem subiektywnej oceny natężenia bólu pacjenci poddani zabiegom przygotowującym do operacji odczuwali mniejsze dolegliwości bólowe, nawet w okresie odległym od zabiegu o 12 tygodni. Można zatem stwierdzić, że wpływ tej fazy rehabilitacji na pooperacyjne metody leczenia, a także czas powrotu do aktywności jest znaczący.
Patients are also advised to stop taking certain medications, especially those that affect blood clotting, to minimize the risk of complications.
Rehabilitation After Treatment
Rehabilitacja po rekonstrukcji więzadeł krzyżowych przednich jest kluczowym elementem procesu powrotu do zdrowia. W pierwszych tygodniach po operacji pacjent korzysta z kul łokciowych, a także, w przypadku uszkodzenia większej ilości struktur z ortezy, aby minimalizować obciążenie operowanego kolana. Ważne jest, aby ściśle przestrzegać zaleceń fizjoterapeuty, co obejmuje stopniowe wprowadzanie ćwiczeń wzmacniających mięśnie oraz pracę nad zakresem ruchu stawu kolanowego.
Całkowity czas trwania rehabilitacji może różnić się w zależności od indywidualnych predyspozycji pacjenta oraz poziomu aktywności, do której zamierza wrócić, ale zazwyczaj w przypadku sportowców lasts from 9 to 12 months. Pełny powrót do aktywności sportowej jest możliwy dopiero po uzyskaniu odpowiedniej siły mięśniowej oraz stabilności stawu kolanowego, which is evaluated based on the results of specialized functional tests.
Risk of Complications After Reconstruction
Various complications can arise after knee ligament reconstruction, which are worth keeping in mind.
Among the most common postoperative complications are the following infections, które objawiają się zaczerwienieniem, obrzękiem i bólem w okolicy operowanej. Dodatkowo okolica przerwania ciągłości skórnej na skutek wykonanego zabiegu operacyjnego może zmienić kolor i wydzielać nieprzyjemny zapach. Jeżeli podejrzewasz zakażenie rany pooperacyjnej natychmiast skonsultuj się z lekarzem.
Hematomas są kolejną możliwą komplikację, charakteryzują się nagromadzeniem krwi pod skórą, co może prowadzić do obrzęków i bólu. W tym wypadku konieczna może się okazać konsultacja z lekarzem w celu wykonania punkcji, mającej za zadanie ewakuację nagromadzonego w tkankach skrzepu krwi.
The effect of any postoperative complication can be delayed recovery, which refers to the healing process of the tissues. Patients may experience prolonged pain, as well as problems restoring full range of motion and muscle strength. It is important to remember that in ligamentous reconstructions with autogenous grafts, the healing process relates to both the reconstruction site and the site from which the tissue was taken. It is important to monitor these symptoms and, if they occur, consult a doctor immediately to avoid more serious consequences.
Physiotherapy and Prevention
Physiotherapy plays a key role in the recovery process after ACL reconstruction of the knee joint. A particularly important aspect for reducing the risk of complications after surgery is proper patient education on:
- The ability to put weight on the operated limb,
- to move independently on different types of surfaces,
- ways to minimize the symptoms of surgical treatment, such as pain and swelling,
- dressing care,
- thromboprophylaxis.
Already from the first day After the operation, the patient should start appropriate exercises, które mają na celu increase in range of motion in the knee joint, muscle strengthening and improving the stability of the joint. Zalecane ćwiczenia obejmują zarówno pasywne ćwiczenia rozciągające, jak i aktywne ćwiczenia wzmacniające mięśnie czworogłowe uda i pozostałe mięśnie stabilizujące kolano.
As rehabilitation progresses, more advanced movement patterns and proprioception training are introduced to help return to daily activities and sports activities.
To avoid future injuries, it is important to continue regular training to strengthen and stabilize the knee, as well as to use proper training techniques. Ongoing contact with a qualified physiotherapist is essential to monitor progress and adjust the rehabilitation plan to suit the patient's individual needs.
Summary
Knee ligament reconstruction is an advanced surgical procedure that is crucial to restoring knee stability. Thanks to arthroscopic techniques, the procedure is less invasive, which speeds up the healing process and minimizes the risk of complications.
Rehabilitation before and after surgery is extremely important and for athletes usually lasts between 9 and 12 months. Exercises to strengthen the muscles and work on the range of motion of the knee joint are key to a full recovery and sports activity.
The methodology of performing the procedure is selected individually for each patient. The doctor, qualifying the patient for the procedure, choosing a specific method, takes into account first of all the time that has passed since the injury and the location of the damage within the structure itself.
The risk of complications, such as infections, hematomas or tissue healing problems, exists, but can be minimized with proper rehabilitation and prompt recognition of unwanted symptoms.
Adequate diagnosis supported by a series of tests and consultation with specialists is very important to confirm the damage and the appropriateness, or lack thereof, of surgical intervention.
