Potential Causes of Knee Pain After Work Out
Knee discomfort following exercise can be bothersome and concerning for fitness lovers.
Knee pain after workout can be a sign of overuse or improper form. Exercise is vital for good health, but improper form or excessive exertion can lead to discomfort or injury.
Understanding the potential causes of knee pain after working out is essential for preventing and addressing this common problem. This blog explores the various factors that can contribute to knee pain after a workout.
Knee Anatomy and Function
Understanding the basics of knee anatomy and function basics is essential for effectively addressing knee pain. While you don’t need to know every detail, having a grasp of the fundamentals will help you follow the topics and concepts related to knee care and treatment discussed in this article.
Introduction to the Knee Joint
The knee has two main joints:
Tibiofemoral Joint: Where the femur (thigh bone) meets the tibia (shin bone).
Patellofemoral Joint: Where the patella (kneecap) meets the femur.
The knee acts like a hinge, primarily allowing it to bend and straighten. It can bend about 135 degrees and extend to a straight line.
Additionally, the knee can perform slight internal and external rotations of the tibia. Stability is provided by the joint’s design and reinforcement from its capsule, ligaments, and tendons.
Role of Muscles, Tendons, and Cartilage in Knee Movement
Knee movement results from the coordinated effort of muscles, tendons, ligaments, and cartilage. Understanding these tissues can help manage knee pain and make recovery more intuitive.
Muscles: Muscles generate the force for knee movement and contribute to its stability. The hamstrings, a group of three muscles at the back of the thigh, act as a natural brace to prevent unwanted movements.
Tendons: Tendons serve as the vital connection between muscles and bones, enabling smooth and coordinated movement throughout the body. Tendons are often involved in knee pain, especially after a workout.
Ligaments: Ligaments connect bones, providing stability. Key knee ligaments include:
Anterior Cruciate Ligament (ACL)
Posterior Cruciate Ligament (PCL)
Medial Collateral Ligament (MCL)
Lateral Collateral Ligament (LCL)
Ligament injuries typically result from trauma and should be assessed by a medical professional.
Cartilage: Cartilage ensures smooth, pain-free movement and absorbs shock. The knee has two types of cartilage:
Articular Cartilage: The femur and tibia ends, as well as the underside of the patella, are protected.
Menisci: Two fibrocartilage rings acting as shock absorbers between the tibia and femur.
Cartilage damage can result from injury or degeneration, leading to osteoarthritis.
Bursas: Bursas are fluid-filled sacs that reduce friction as tendons slide over the knee joint. The four primary knee bursas are:
Suprapatellar Bursa
Infrapatellar Bursa
Prepatellar Bursa
Semimembranosus Bursa
If necessary, inflamed bursas, a condition known as bursitis, can be managed with activity modification or corticosteroid injections.
Causes of knee pain after workout
Recognizing the various knee pain causes and symptoms can help you determine the problem and seek appropriate treatment. Causes of joint or knee pain after workout include:
1- Bursitis
Bursitis occurs when a bursa, a fluid-filled sac that cushions your bones, muscles, and tendons, becomes irritated and swollen. It can be caused by injury, overuse, repeated pressure, infections, or arthritis.
Symptoms:
Pain and tenderness in the front of the knee.
Pain during movement and at rest.
Redness, swelling, or warmth.
Stiffness
2- Iliotibial Band Friction Syndrome (ITBFS)
ITBFS is an overuse injury in which the iliotibial band, a tendon around the leg, rubs against the bone. It commonly affects athletes, especially runners and cyclists.
Symptoms:
Pain on the outer knee.
Pain worsens with activity, especially when bending the knee.
3- Jumper’s Knee
Jumper’s knee, or patellar tendinitis, results from repetitive jumping activities. It primarily affects athletes aged 15-30.
Symptoms:
Pain below the kneecap.
Stiffness while climbing stairs, jumping, or kneeling.
4- Ligament Tears
The anterior cruciate (ACL) and medial collateral ligament (MCL) are commonly torn, causing instability, pain, and swelling. Injuries often occur during sports.
Symptoms:
Popping sound at the time of injury.
Instability in the knee.
Pain and swelling within hours of injury.
5- Meniscus Tears
A meniscus tear can occur from twisting the knee, heavy lifting, or sudden directional changes.
Symptoms:
Knee locking
Pain worsened by pressure or walking.
Swelling
6- Osteoarthritis (OA)
Osteoarthritis develops when joint cartilage breaks down over time, typically due to prolonged use. This condition is frequently observed in elderly individuals.
Symptoms:
Pain worsened by activity or prolonged periods of rest.
Stiffness and swelling.
Grinding or scraping noises while walking.
7- Runner’s Knee
Runner’s knee, or patellofemoral pain syndrome (PFPS), causes tenderness and a grating sensation around the kneecap.
Symptoms:
Pain worsened by climbing stairs, running, or squatting.
Tenderness around the kneecap,
8- Strains and Sprains
Strains (muscle tears) and sprains (ligament injuries) result from excessive physical activity, improper warm-up, or poor flexibility.
Symptoms:
Bruising or skin discolouration
Joint stiffness and pain.
Swelling
9- Infection
Infectious arthritis occurs when infections spread to the knee, causing pain and inflammation.
Symptoms:
Chills and fever.
Difficulty moving the affected joint.
Red, swollen joints
10- Dislocated Kneecaps
A dislocated kneecap typically occurs from a direct impact or awkward twist.
Symptoms:
Popping sound at injury.
Extreme pain
Visible dislocation
11- Fractured Kneecaps
Fractures often result from car accidents or falls, causing pain near the front of the knee.
Symptoms:
Fluid build-up in the knee.
Unstable feeling
Tenderness and trouble climbing stairs.
Home Remedies for Knee Pain
For non-severe knee pain, consider the following home remedies:
Rest and apply ice.
Elevate the knee.
Wear an elastic bandage or sleeve.
Take over-the-counter pain relievers.
Knee pain after workout can stem from various factors, including overuse, poor form, inadequate footwear, muscle imbalances, previous injuries, improper warm-up and cool-down, overweight, lack of flexibility, and improper progression.
By grasping these underlying causes and adopting preventive measures, you can lower the likelihood of experiencing knee discomfort and sustain your enjoyment of physical fitness.
