As a physical therapist, I have seen many patients with knee injuries and conditions. Understanding the anatomy and function of the knee joint is essential to prevent injuries, manage pain, and recover from surgery. In this article, I will explain the basic structure of the knee, the role of ligaments and tendons, and the muscles responsible for movement.
The knee joint is the largest joint in the body and connects the thigh bone (femur) to the shin bone (tibia). The kneecap (patella) is a small bone that sits in front of the knee joint and protects the joint. The knee joint is a hinge joint that allows for flexion and extension of the leg. It also has some rotational movement, which is important for activities such as walking and running.
The knee joint is supported by several ligaments and tendons. Ligaments are tough bands of tissue that connect bones to bones, while tendons connect muscles to bones. The ligaments and tendons around the knee joint work together to provide stability and support to the joint. In the next section, I will discuss the role of these structures in more detail.

Understanding the basic structure and function of the knee joint is essential for preventing injuries, managing pain, and recovering from surgery.
Basic Structure of the Knee
As the largest joint in the body, the knee is a complex structure that allows us to walk, run, jump, and perform other physical activities. It is a synovial joint, meaning it contains a fluid-filled capsule that lubricates the joint and reduces friction during movement.
Bones and Joints
The knee joint is formed by the articulation of three bones: the femur, tibia, and patella. The femur, or thigh bone, is the longest bone in the body and forms the upper part of the knee joint. The tibia, or shin bone, is the larger of the two bones in the lower leg and forms the lower part of the knee joint. The fibula is the smaller bone in the lower leg and is not directly involved in the knee joint.
The knee joint is actually two joints in one: the tibiofemoral joint and the patellofemoral joint. The tibiofemoral joint is the main joint between the femur and tibia, while the patellofemoral joint is the joint between the patella and the femur.
Patella
The patella, or kneecap, is a sesamoid bone that sits in front of the knee joint and helps to protect the knee and improve the leverage of the quadriceps muscle. The patella is unique in that it is not directly attached to any other bone in the body. Instead, it is connected to the quadriceps tendon and the patellar ligament.
In summary, the knee joint is a complex structure that is formed by the articulation of three bones: the femur, tibia, and patella. The knee joint is actually two joints in one: the tibiofemoral joint and the patellofemoral joint. The patella, or kneecap, is a sesamoid bone that sits in front of the knee joint and helps to protect the knee and improve the leverage of the quadriceps muscle.
Knee Ligaments and Tendons
The knee joint is stabilized and supported by a network of ligaments and tendons. These structures work together to provide strength and stability to the knee joint, allowing us to perform various activities such as walking, running, and jumping.
Collateral Ligaments
The collateral ligaments are located on the sides of the knee joint. The medial collateral ligament (MCL) is located on the inner side of the knee, while the lateral collateral ligament (LCL) is found on the outer side. These ligaments help to prevent excessive side-to-side movement of the knee joint.
Cruciate Ligaments
The cruciate ligaments are located inside the knee joint and cross each other to form an “X” shape. The anterior cruciate ligament (ACL) is located in the front of the knee, while the posterior cruciate ligament (PCL) is located at the back. These ligaments help to prevent excessive forward and backward movement of the knee joint.
Tendons
The patellar tendon and quadriceps tendon are two important tendons that are located in the knee joint. The patellar tendon connects the patella (kneecap) to the tibia (shinbone), while the quadriceps tendon connects the quadriceps muscle to the patella. These tendons help to provide stability to the knee joint and allow us to perform various movements such as jumping and climbing stairs.
In summary, the knee joint is stabilized and supported by a network of ligaments and tendons. The collateral ligaments help to prevent excessive side-to-side movement of the knee joint, while the cruciate ligaments help to prevent excessive forward and backward movement. The patellar and quadriceps tendons provide stability to the knee joint and allow us to perform various movements.
Muscles and Movement of the Knee
The knee joint is a hinge joint that allows for flexion and extension of the lower leg. The movement of the knee is controlled by a complex system of muscles, tendons, and ligaments that work together to stabilize and move the joint.
Anatomical illustration of the human knee joint, showing all the components along with their names. This includes the bones, ligaments, cartilage, and tendons, with clear labels for each part such as the femur, tibia, fibula, patella, meniscus, and various ligaments and tendons.
Quadriceps Muscles
The quadriceps muscles are a group of four muscles located on the front of the thigh that work together to extend the knee joint. These muscles include the rectus femoris, vastus lateralis, vastus intermedius, and vastus medialis. The rectus femoris also works to flex the hip joint.
Hamstring Muscles
The hamstring muscles are a group of three muscles located on the back of the thigh that work together to flex the knee joint. These muscles include the biceps femoris, semitendinosus, and semimembranosus. The gracilis muscle also works to flex the knee joint.
Movements of the Knee
The knee joint allows for a variety of movements, including flexion, extension, lateral rotation, and medial rotation. Flexion is the movement that brings the heel towards the buttocks, while extension is the movement that straightens the leg. Lateral rotation is the movement that turns the lower leg outward, while medial rotation is the movement that turns the lower leg inward.
The popliteus muscle is a small muscle located at the back of the knee joint that works to unlock the knee joint during flexion. The flexors and extensors of the knee joint work together to stabilize the joint during movement.
The tibiofemoral joint is the main joint of the knee, while the patellofemoral joint is the joint between the kneecap and the femur. The articularis genus muscle is a small muscle located at the front of the knee joint that works to pull the synovial membrane of the joint upward during extension.
The gastrocnemius and plantaris muscles are located at the back of the knee joint and work to plantarflex the ankle joint. Instability of the knee joint can lead to pain and difficulty with activities such as running and walking.
Knee Injuries and Treatment
Common Knee Injuries
The knee is a complex joint that is susceptible to a variety of injuries. Some common knee injuries include:

This in-depth knee guide covers everything you need to know about knee anatomy, morphology, function, and common problems. Read on to learn how your knees work so you can keep them in top shape!
Knee Joint Anatomy
The knee joint connects three bones: the femur (thighbone), tibia (shinbone), and patella (kneecap). These bone structures provide the foundation of the knee.
Knee joint components:
Femur
Tibia
Patella
Joint capsule
Cartilage
Synovial membrane
Menisci
Ligaments
Tendons
Muscles
Nerves and blood vessels
The ends of the femur and tibia are covered in articular cartilage, a smooth substance that protects the bones and allows them to glide smoothly against each other.
The whole knee joint is surrounded by a joint capsule lined with synovial membrane. This produces synovial fluid that lubricates the joint and reduces friction.
There are two menisci between the femur and tibia – the medial meniscus and lateral meniscus. These C-shaped discs of cartilage act as cushions or shock absorbers in the knee.
Ligaments connect bones and provide stability to the knee:
Tendons connect muscles to bones. The quadriceps and patellar tendons are key structures that straighten the knee.
Powerful muscles like the quadriceps and hamstrings control knee movement. Smaller muscles provide additional support.
Nerves carry messages between the knee and brain to facilitate movement. The knee joint also has a rich blood supply to provide nutrients.
Knee Morphology
Knee morphology refers to the shape and form of the knee joint structures. Here are some key morphological features:
The femur has two rounded condyles that sit on the flat tibial plateau. This shape allows the knee to flex, extend, and rotate.
The patella is a triangular sesamoid bone embedded within the quadriceps tendon. It protects the knee joint and increases quadriceps leverage.
Menisci are crescent-moon shaped discs between the femur and tibia. This distributes body weight and provides congruency.
Collateral ligaments run vertically on the medial and lateral knee to resist side-to-side motion.
Cruciate ligaments cross each other inside the joint to enable rotation while limiting front-to-back translation.
Muscles like the quadriceps have large attachment sites for strong contraction leverage.
Articular cartilage is smooth and dome-shaped over bony surfaces to facilitate gliding.
The synovial membrane lines the joint capsule and folds into crevices for lubrication access.
Understanding the shape and alignment of knee structures is critical when diagnosing injuries or dysfunction.
Knee Joint Function and Biomechanics
The complex anatomy of the knee allows for specialized motions and weight bearing functions.
Main Knee Functions
Flexion and extension for walking, running, and jumping
Slight internal and external rotation for foot positioning
Weight bearing as the body’s central support joint
Shock absorption to reduce impact loading
Knee Flexion and Extension
The femur and tibia rotate against each other to produce knee flexion and extension. This hinge-like motion ranges from 0° when straight to over 140° during deep flexion.
Key structures involved in knee flexion:
Hamstrings – Flex the knee by pulling the tibia posteriorly
Gastrocnemius – Flexes knee through its connection with the hamstrings
Popliteus – Rotates femur internally during flexion
Key structures for knee extension:
Quadriceps – Straighten the knee by pulling the patella and tibia anteriorly
Soleus – Assists knee extension via synergy with the gastrocnemius
Knee Rotation
The knee joint can rotate slightly inward and outward when flexed to position the foot and lower leg. This is mediated by:
Popliteus – Internally rotates the femur
Iliotibial band – Facilitates external femoral rotation
Rotational stability is provided by the cruciate ligaments and collateral ligaments.
Shock Absorption and Impact Reduction
The knee joint structures work together to reduce damaging impact forces:
Menisci – Act as shock absorbers between the femur and tibia
Cartilage – Compresses to cushion bone articulation
Ligaments – Provide dynamic restraint to overloaded joints
Muscles – Eccentrically contract to dissipate energy
Proper knee biomechanics are essential for absorbing up to 6 times your body weight during activities like jogging!
Common Knee Problems and Injuries
Due to its complexity and heavy use, the knee joint is susceptible to various injuries and pathologies. Some of the most common knee problems include:
Sprains and Strains
Medial collateral ligament (MCL) sprain – Overstretching or tearing of the MCL from impact or twisting. Causes inner knee pain and laxity.
Lateral collateral ligament (LCL) sprain – Injury to the LCL from hyperextension or direct trauma. Results in outer knee pain.
Patellar tendon strain – Overload and inflammation where the tendon attaches to the tibia. Causes anterior knee pain.
Quadriceps/hamstring strain – Muscle overuse leading to partial tears and weakness. Hampers knee stability.
Meniscal Injuries
Meniscus tear – Occurs when abruptly twisting or rotating the knee. Torn menisci cause pain, catching, locking, and swelling.
Discoid meniscus – An abnormal thickened meniscus prone to tearing. More common medially.
Degenerative meniscal tear – Fraying and deterioration seen with aging. Associated with osteoarthritis.
Ligament Tears
ACL tear – Sudden change in direction tears the ACL. Instability, pain, and swelling follow.
PCL tear – Hyperextension injury that strains or tears the PCL. Posterior knee pain and laxity result.

Frequently Asked Questions About the Knee Joint
Here are answers to some frequently asked questions about knee anatomy, function, injuries, and care:
What are the four bones of the knee?
The four bones that form the knee joint are the femur, tibia, fibula, and patella. The femur is the thigh bone, the tibia is the shin bone, and the patella is the kneecap. The fibula runs parallel to the tibia but does not directly articulate with the knee.
What does the ACL do?
The anterior cruciate ligament (ACL) runs diagonally through the middle of the knee to prevent the tibia from sliding forward in relation to the femur. ACL tears are unfortunately very common knee injuries, especially in sports that involve pivoting.
Why does my knee make a cracking or popping sound sometimes?
Occasional cracking or popping sounds are fairly normal in the knee and generally nothing to worry about. This can occur from tendons sliding over bony bumps or gases releasing from the fluid-filled joint spaces during movement.
What causes knee buckling?
Knee buckling or instability has multiple potential causes, including ligament tears, meniscus tears, knee arthritis, knee cap tracking problems, muscle weakness, and nerve injuries. Having a sudden giving out of the knee should be evaluated by a medical professional.
What are the symptoms of a meniscus tear?
Common symptoms of a torn meniscus include knee pain, swelling, catching or locking during activity, and a feeling that the knee may give out. Tenderness along the joint line and limited range of motion are also possible.
How long does it take to recover from knee surgery?
The recovery time after knee surgery depends on the specific procedure performed. Minor arthroscopic surgery may require only 2-4 weeks for return to normal activities, while major reconstructive surgery can take 4-9 months for full recovery. Following all post-op protocols can optimize results.
What are the best knee exercises?
Some of the best knee exercises to strengthen the structures around the joint include: quad sets, straight leg raises, heel slides, knee extensions, hamstring curls, squats, lunges, and calf raises. Low-impact exercises like swimming and cycling are also great knee-friendly options.
What causes knee osteoarthritis?
Knee osteoarthritis develops from wear and tear to the joint over time. Contributing factors include aging, obesity, joint injury, repetitive impact, muscle weakness, and misalignment. Genetics can also play a role in the degeneration of the knee cartilage, synovium, and underlying bone.
How can I tell if I sprained my MCL?
Symptoms of a grade 1 or 2 MCL knee sprain include pain on the inner knee, swelling, and tenderness over the MCL. There is usually no joint instability. A complete MCL tear can cause significant inner knee instability with valgus force. Imaging or physical exam by a doctor can confirm an MCL sprain.
