Unstable Knee: Symptoms, Causes, and Treatment

Ett instabilt knä kan orsaka betydande obehag och begränsa rörligheten

An unstable knee can cause significant discomfort and limit mobility. This article reviews the most common symptoms, causes, and treatment options for unstable knees, as well as how specialized knee braces can help.

What is an unstable knee?

An unstable knee occurs when the structures that support the knee joint, such as ligaments, muscles, or menisci, are damaged or weakened. This can lead to a feeling of uncertainty and instability in the knee – a common symptom of, for example, meniscus or cruciate ligament injuries.

Symptoms of unstable knee

Common symptoms of an unstable knee include:

  • Feeling that the knee is "giving way" or is unstable
  • Pain, especially with strain or movement
  • Swelling around the knee joint
  • Reduced mobility in the knee
  • Difficulty performing certain movements or activities

These symptoms may resemble knee pain when walking and bearing weight, but are often linked to underlying instability.

Causes of unstable knee

An unstable knee can be caused by several factors:

  • Ligament injuries (e.g. cruciate ligament injury or collateral ligament injury)
  • Meniscus injuries
  • Osteoarthritis
  • Muscle weakness around the knee
  • Previous knee injuries

Instability can also occur in connection with knee osteoarthritis, where the cartilage gradually breaks down.

Diagnosis and treatment of unstable knee

Unstable knee means that the knee feels weak, gives way or moves abnormally when loaded. The condition can be caused by ligament damage, meniscus problems or impaired muscle control. The diagnosis is usually made through a physical examination, the patient's medical history and sometimes imaging tests such as MRI or ultrasound.

Treatment is tailored to the cause of the instability and often includes a combination of exercise, supportive devices and, if necessary, medical or surgical treatment.

Physiotherapy

Physiotherapy is the mainstay of treatment for an unstable knee. Specific exercises strengthen the muscles around the joint, which improves stability and control. Rehabilitation also focuses on balance and coordination to reduce the risk of future injuries.

Knee pads with splints

In cases of ongoing discomfort, knee braces with splints can be used to provide extra support and reduce the strain on damaged structures. These aids stabilize the joint during movement and are often used during activities that involve high stress on the knee.

Anti-inflammatory drugs

Painkillers and anti-inflammatory medications can relieve pain and reduce swelling associated with inflammation or overuse. The treatment facilitates movement and allows rehabilitation to be performed without discomfort.

Operation

In cases of severe damage to the ligaments or other stabilizing structures of the knee, surgery may be necessary. The surgery aims to repair or replace the damaged tissues to restore normal knee function. After surgery, a longer rehabilitation period follows to build strength and stability.
