knieletsel

Knieletsel is a Norwegian term that refers to injuries of the knee joint, including damage to ligaments, menisci, cartilage, tendons, bones, or soft tissues surrounding the knee. It is a broad category that encompasses acute trauma as well as overuse injuries.

Causes and common types

Knee injuries often result from sports activities, falls, direct blows, or sudden twists of the knee. Common injuries include ligament tears (such as to the anterior cruciate ligament, ACL, or medial collateral ligament, MCL), meniscal tears, patellar dislocations or maltracking, tendon injuries (such as patellar tendonitis or quadriceps tendon injuries), and osteochondral injuries involving cartilage and bone. Fractures and contusions can also occur.

Symptoms

Symptoms vary by type but typically include knee pain, swelling, reduced range of motion, instability or a sensation of the knee “giving way,” tenderness around the joint, and sometimes a catching or locking sensation.

Diagnosis

Evaluation combines patient history with a physical examination to assess stability and range of motion. Imaging begins with X-rays to exclude fractures; MRI is commonly used to evaluate ligaments, menisci, and cartilage. In some cases ultrasound or CT scans may be employed.

Treatment

Acute knee care follows standard first aid: rest, ice, compression, and elevation, with analgesics as needed. Nonoperative management is common for minor ligament sprains and certain meniscal tears, including physical therapy and activity modification. Bracing or crutches may be used temporarily. Surgical treatment is considered for significant ligament injuries (for example ACL tears in active individuals), complex meniscal tears, patellar instability, or certain fractures, often followed by structured rehabilitation. Return to sport depends on injury type and recovery progress.

Prognosis and prevention

Recovery varies with injury type and severity, ranging from weeks to months or longer for surgical cases. Prevention focuses on strength and neuromuscular conditioning, proper technique, and protective equipment in risky activities.
