Knee sprain

A knee sprain occurs when the ligaments that stabilise the knee joint are stretched or torn due to sudden movements.

Symptoms

Acute pain may occur during the initial trauma. Oedema (swelling) may occur due to the inflammatory response, as well as instability, with a feeling of weakness or inability to bear weight. Sprains can be graded: Grade I - Mild stretching of the ligaments; Grade II - Partial rupture of the ligaments; Grade III - Complete rupture of the ligaments.

Risk Factors

Contact sports or sports involving rapid changes of direction; Weak muscles around the knee can increase the risk; Previous injuries can predispose to sprains.

Protective Factors

Exercises to strengthen the quadriceps and hamstrings; Correct execution of movements and physical activities; Use of protective equipment in risky sports.

Treatment

R.I.C.E.: Rest, Ice, Compression and Elevation for initial symptom control. Exercises for muscle strengthening, stretching and improving stability; In severe cases, immobilisation using a splint or orthosis may be necessary; In cases of severe ruptures or associated injuries, surgery may be indicated.
