The knee is one of the most complex joints in the human body. It connects the thigh to the lower leg and is supported by ligaments, tendons, muscles, and cartilage. When any of these structures is damaged, it is considered a knee injury.

A knee injury can occur suddenly, for example from twisting your leg during sports or taking a misstep. However, in practice, knee problems often develop gradually. This is especially common in people with sedentary jobs and limited daily movement, or in those who suddenly increase their physical activity. Think of someone who starts running again after years off, goes on long cycling trips, or trains intensely in the gym.

In these cases, it usually isn’t just a single moment of “overload” that causes the injury, but a combination of factors: weak muscles around the knee and hip, poor posture or gait, shoes that don’t provide adequate support, or simply too little recovery time between activities. Being overweight can also play a role, as it puts additional stress on the joint.

As a result, the knee becomes gradually irritated, and symptoms build up over time. This explains why knee injuries often start subtly and only become noticeable during everyday activities such as climbing stairs, cycling, or standing for long periods.

Recognizing knee injury symptoms

Knee injuries can show up in different ways depending on their severity. Typical signs include swelling, stiffness, pain during movement, or difficulty bearing weight. Some people notice popping or cracking sounds when moving the knee. Chronic overuse injuries may appear as persistent discomfort after prolonged sitting, walking, or light exercise.

Even minor knee pain should not be ignored. Addressing issues early often prevents more serious damage and reduces recovery time.

What to do when you have a knee injury

When you experience a knee injury, it’s important to give your knee rest, but that doesn’t mean lying down for weeks. Gentle movements, like slow walking or gradually bending and straightening the knee, help improve blood flow, prevent stiffness, and support healing.

If your knee swells or hurts, elevating it and applying a cold pack can reduce swelling and pain. Keep an eye out for warning signs that require professional help:

These could indicate a more serious injury, such as a ligament or meniscus tear. In such cases, consulting a physiotherapist or orthopaedist is essential.

Even mild knee issues can benefit from professional guidance. A physiotherapist can assess your knee, recommend exercises for strength and stability, and help you return safely to daily activities and sports.

Who can help with knee problems?

A physiotherapist is usually your first point of contact for a knee injury. They assess which structures are affected, advise on movement and load, and guide you through exercises that accelerate recovery. Studies show that active exercise therapy is often as effective—or even more effective—than surgery for mild to moderate knee injuries.

A personal trainer with medical expertise can also help you strengthen the muscles around your knee and hips, reducing the risk of future injuries. In Amsterdam, several studios combine physiotherapy and personal training to optimize rehabilitation.

Exercises and strengthening tips

Targeted exercises can improve knee stability, reduce pain, and prevent future injuries. Here are some effective options:

Start slowly and increase repetitions as tolerated. Stop any exercise that causes pain and consult a professional if needed.

Preventing knee injuries

Prevention is always better than cure. Some key tips include:

Research shows that a combination of strength training, balance exercises, and gradual activity increases significantly reduces the risk of knee injuries, particularly in middle-aged adults and those with sedentary lifestyles (Lauersen et al., 2014).
