Why Knee Pain Happens

The knee is a strong but complex joint. It connects the thigh bone, shin bone, and kneecap and is supported by muscles, tendons, and ligaments. Because we use our knees for walking, bending, climbing, and lifting, they experience constant pressure. When something goes wrong in this system, pain can occur.

Understanding the cause of your discomfort is the first step toward the right knee pain treatment. Below are some of the most common reasons people develop knee pain.

1. Overuse or Repetitive Strain

Many people experience knee pain from simply doing too much. Activities like running, jumping, or even long walks can strain the knee joint over time. This is especially common in athletes or people who suddenly increase their activity level.

Overuse injuries often cause inflammation, swelling, and soreness around the knee. Physical therapy is an excellent form of knee pain treatment because it trains the muscles to support the joint better and reduces irritation caused by repeated movement.

2. Muscle Weakness or Imbalance

Your knees depend on strong and balanced muscles—especially the quadriceps, hamstrings, and hip muscles. When these muscles are weak or uneven, the knee absorbs extra pressure that should be handled by the surrounding muscles.

A physical therapist at New Moon Physiotherapy can evaluate your movement patterns and create a personalized knee pain treatment plan to strengthen your legs, improve balance, and reduce stress on the joint.

3. Arthritis

Arthritis is a very common cause of knee pain, especially in older adults. The most common type, osteoarthritis, happens when the cartilage in the knee slowly wears down over time. This can cause stiffness, swelling, and pain that makes everyday tasks more difficult.

While arthritis cannot be cured, physical therapy offers effective knee pain treatment that focuses on increasing flexibility, improving strength, and maintaining mobility so you can stay active without worsening your symptoms.

4. Sprains and Strains

Sprains and strains happen when ligaments or muscles are stretched too far or torn. These injuries often occur during sports, falls, or sudden twisting movements.

A sprain or strain can cause sharp pain, swelling, and difficulty putting weight on the leg. With guided knee pain treatment, your therapist can help you heal safely, restore strength, and prevent reinjury.

5. Meniscus Tears

The meniscus is a piece of cartilage that cushions your knee joint. A sudden twist or deep squat can tear the meniscus, leading to pain, swelling, and locking or clicking sensations.

Many people think meniscus tears always require surgery, but that is not always true. In many cases, physical therapy is a successful knee pain treatment option that helps the knee regain mobility and strength without invasive procedures.

6. Patellofemoral Pain Syndrome (Runner’s Knee)

Runner’s knee is one of the most common knee problems, especially in active individuals. It happens when the kneecap does not move correctly along the groove of the thigh bone.

Symptoms include pain when climbing stairs, kneeling, squatting, or sitting for long periods. Physical therapy focuses on alignment, strengthening, and stretching—making it a very effective knee pain treatment for this condition.

7. Tendonitis

Tendonitis occurs when the tendons around the knee become irritated or inflamed. The most well-known type is “jumper’s knee,” which affects the patellar tendon below the kneecap.

Tendonitis often develops from repetitive jumping, running, or other high-impact movements. Physical therapy provides targeted knee pain treatment to reduce inflammation, strengthen the tendons, and restore normal movement.

8. Poor Posture or Movement Patterns

Sometimes knee pain is not caused by an injury at all—it can come from the way you stand, walk, or move. Poor posture, flat feet, or misalignment in the hips or spine can put extra strain on the knees.

A physical therapist can analyze your posture and gait to see what might be contributing to your pain. With a personalized knee pain treatment plan, you can correct these patterns and reduce stress on the joint.

9. Acute Injuries from Falls or Accidents

Falls, car accidents, and sports collisions can all lead to sudden knee injuries. These may involve torn ligaments, damaged cartilage, or bruising around the joint.

Acute injuries require proper evaluation and a structured recovery plan. Physical therapy is often recommended as part of knee pain treatment to improve healing, build strength, and support safe movement during recovery.

How Physical Therapy Helps

No matter the cause of your knee pain, physical therapy is one of the best ways to treat it. At New Moon Physiotherapy, your therapist will complete a full evaluation to identify what’s causing your symptoms. Then, they will develop a customized knee pain treatment plan that may include:

  • Strengthening exercises

  • Flexibility and stretching routines

  • Manual therapy

  • Balance and stability training

  • Posture and movement correction

  • Education on activity modification

  • Home exercise plans

The goal of knee pain treatment is not only to reduce pain but also to prevent it from coming back. By improving strength, mobility, and alignment, physical therapy helps you move with confidence and avoid future injuries.

When to Seek Professional Help

You should consider professional knee pain treatment if:

  • Your pain lasts longer than a few days

  • You notice swelling or stiffness

  • You have trouble walking or bending the knee

  • Your knee feels unstable or gives out

  • You hear clicking or popping

  • You want to prevent the pain from getting worse

Ignoring knee pain can lead to more serious issues, so early treatment is always the best choice.
