Duration of a sprained knee
Since the knee is a rather large joint, which is also under heavy strain and is also rather difficult to spare, sprains on the knee often take longer to heal. If it has been ruled out with certainty that there are other injuries on or in the knee, strict sparing usually leads to an improvement of the situation within 3 to 4 weeks. If there was already a suspicion of ligament or cartilage damage beyond the sprain immediately after the injury, further clarification of any existing complaints should be carried out after this time at the latest.
Magnetic resonance imaging (MRI) is best suited to clarify these issues. Nevertheless, in individual cases, healing of a sprain can of course take longer than a month without further injuries. In case of doubt, an experienced orthopedist or trauma surgeon should be consulted.
