Knee pain is one of the most widespread musculoskeletal complaints, affecting people of all ages—from active athletes to older adults facing joint degeneration. The knee is a complex structure made up of bones, ligaments, tendons, cartilage and soft tissues. When any of these components become injured or irritated, pain can quickly become a barrier to your daily mobility. Many individuals turn to professional rehabilitation options like Knee Pain Treatment in London to regain full movement and reduce discomfort effectively.
Understanding what’s causing your knee pain is the key to finding the right solution. Below, we explore ten common reasons behind knee pain and explain how each condition can be treated for long-lasting relief.
1. Osteoarthritis
Osteoarthritis is one of the leading causes of knee pain, especially among individuals over 40. As the protective cartilage gradually wears down, the bones begin to rub against each other, causing stiffness, swelling and persistent discomfort. Symptoms often worsen in the morning or after prolonged sitting. Treatment typically involves physiotherapy to strengthen supporting muscles, improving joint flexibility, weight management to reduce knee stress, and low-impact movements to maintain mobility without aggravating the joint.
2. Patellofemoral Pain Syndrome (Runner’s Knee)
Patellofemoral Pain Syndrome causes pain around or behind the kneecap. It usually develops due to muscle imbalances, improper foot mechanics, or overuse from running and jumping. People often experience increased pain while climbing stairs, squatting or sitting for long periods. Treatment focuses on strengthening the quadriceps, hips and glutes while addressing misalignment issues. Manual therapy and corrective exercises provided by trained physiotherapists help significantly.
3. Ligament Injuries (ACL, MCL, PCL)
Ligament injuries happen frequently in sports that involve sudden stops, pivots, or collisions. The ACL is the most commonly injured ligament, and such injuries often cause immediate swelling, instability and difficulty bearing weight. Depending on severity, treatment may range from structured physiotherapy programs to surgical intervention followed by comprehensive rehabilitation. Early diagnosis is vital to prevent long-term knee instability.
4. Meniscus Tears
A meniscus tear often occurs when the knee twists while bearing weight. The meniscus acts as a shock absorber between the thigh and shin bones, and a tear can cause locking, clicking, and swelling. While mild tears may heal with rest and physiotherapy, more severe tears might require surgical repair. Strengthening surrounding muscles and improving balance helps reduce strain on the meniscus going forward.
5. Tendonitis (Jumper’s Knee)
Tendonitis develops when the tendon connecting the kneecap to the shinbone becomes irritated or inflamed. This condition is common in athletes who jump, sprint or change directions quickly. Symptoms include sharp pain during activity, tenderness just below the kneecap and stiffness after rest. Treatment typically involves rest, gradual strengthening, stretching and correcting movement patterns that overload the tendon.
6. Bursitis
The knee contains several bursae—small fluid-filled sacs that reduce friction. When these become inflamed due to overuse, prolonged kneeling or direct impact, bursitis develops. The pain often feels warm and tender to the touch. Reducing activities that irritate the area, applying ice and using physiotherapy to improve mechanics usually leads to recovery. At this stage, many patients explore supportive treatment options at a Trusted Physiotherapy Clinic to manage swelling and restore mobility.
7. IT Band Syndrome
The iliotibial (IT) band runs along the outside of the thigh and can become overly tight due to poor biomechanics or muscle weaknesses. When the IT band rubs against the outer part of the knee, it creates sharp pain, especially during running. Treatment includes releasing tight tissues, strengthening the hips and glutes, enhancing posture and working on movement patterns to prevent recurrence.
8. Gout
Gout is an inflammatory type of arthritis caused by elevated uric acid levels that crystallize in the joints. While it commonly affects the big toe, the knee is another frequent target. Gout attacks cause sudden, intense pain, swelling, heat and redness. Managing gout involves medication, dietary adjustments, hydration and gentle physiotherapy once inflammation reduces.
9. Overuse Injuries
People who suddenly increase their physical activity levels often develop knee pain due to overuse. Activities like running long distances without proper buildup, repetitive kneeling or excessive jumping can place strain on the joint. Treatment focuses on reducing activity intensity, improving strength and flexibility, and gradually returning to exercise under professional guidance.
10. Poor Alignment or Muscle Weakness
Muscle imbalances—particularly in the hips, thighs and glutes—affect how the knee moves and absorbs impact. Weakness or misalignment can place excessive pressure on the joint, causing pain over time. Physiotherapists often use targeted strengthening, gait correction and posture training to restore proper mechanics and reduce knee stress.
When to Seek Professional Knee Pain Treatment
If knee pain continues for more than a few days, limits mobility or becomes progressively worse, it’s important to seek help. Early intervention prevents small issues from developing into chronic problems. Physiotherapists play a crucial role in diagnosing the root cause and recommending personalised treatment plans that promote healing and long-term joint health.

Final Thoughts
Knee pain can result from various conditions—some minor, others more serious. Understanding the underlying cause is essential for choosing the right treatment and preventing future complications. With the right physiotherapy approach, most people can regain strength, flexibility and pain-free movement. If knee pain is affecting your quality of life, seeking professional assessment is the first step toward lasting relief.
