Many people experience knee soreness after exercise, and most simply apply some liniment and call it a day. However, due to the complex structure of joints, issues with ligaments or cartilage that aren't addressed promptly can worsen over time, potentially leading to irreversible damage.
Knee pain from running—which type do you have?
First, to treat the condition effectively, you must identify its cause. Running-induced knee pain stems from various sources, but the three most common are: osteoarthritis, patellar chondromalacia, and runner's knee (iliotibial band syndrome).
If you experience pain at the knee joint itself, you can perform some simple self-tests (though for other symptoms or severe cases, consult a doctor~), as the pain points differ for each condition.
Osteoarthritis pain is located in the joint space between the bones of the knee. It often manifests as discomfort when pressure is applied to the knee while standing upright. Sometimes, arthritis can also cause swelling and pain.
Key relief for osteoarthritis lies in strengthening the quadriceps muscles. We previously introduced a seated leg curl exercise for this purpose, which is highly effective.
Pain from patellar chondromalacia occurs beneath the small protrusion above the knee joint (the patella itself). This condition causes not only pain but also a feeling of weakness and soreness.Generally, if pain and weakness occur when bending your knee between 60° and 90°, it is most likely caused by patellar chondromalacia.
Iliotibial band syndrome, also known as runner's knee, has a different pain location than the above two conditions, primarily on the outer side of the knee joint. Pain often occurs when the knee is bent between 30° and 60°.IT band syndrome is most common among runners and cyclists. Six Simple Tips for Knee Pain Relief 1. Thorough Warm-Up Increase body temperature to reduce muscle and ligament stiffness, making muscles more pliable and ligaments more elastic. This reduces stress on the knees during activity.Increase joint range of motion, stimulate synovial fluid production, and reduce knee wear. This facilitates easier extension and contraction during exercise while significantly improving coordination. 2. Functional Training to Enhance Knee Stability For example, lie flat on your back with knees straight and perform straight-leg raises without weight-bearing.If no significant knee pain occurs, use a sandbag made from old clothing placed on the top of the foot to perform straight-leg weight-bearing lifts.
3. Strength Training for Leg Muscles to Promote Blood Circulation
For example, hold onto the back of a chair while standing and perform horse stance squats.Initially, maintain a fixed knee height without bending. Gradually increase knee flexion only after confirming no adverse reactions. This effectively accelerates muscle blood flow.
4. Minimize Unnecessary Movement
Activities like deep squats that involve repetitive knee bending should be avoided by those with knee discomfort, as they accelerate joint wear.Avoid prolonged running, jumping, or squatting, and minimize or avoid stair climbing. 5. Self-Protection Awareness Refrain from frequently squatting or kneeling to pick up objects. Also avoid sitting on low stools or sleeping on low beds to prevent increased joint friction and load.Additionally, apply warm compresses to the knees after exercise. 6. Strengthen Leg Muscles Particularly, robust thigh muscles provide essential protection for the knee joint. Strong quadriceps (front thigh muscles) and tensor fascia latae reduce impact on the patella and meniscus during movement—common causes of anterior knee pain.
The tensor fascia lata is connected to the iliotibial band, and many cases of lateral knee pain stem from iliotibial band issues. There are various ways to exercise thigh muscles, such as lunges, squats, stair climbing, and wall sits.
