What could cause numbness in the right knee?

Numbness around the knee can happen when nerves in that area do not work well. One reason might be an injury to the peroneal nerve, which runs near the knee and can be hurt by a blow or pressure. After knee surgery, sometimes the small nerves under the skin can be affected, leading to numbness. In some cases, a Baker’s cyst—a fluid-filled swelling behind the knee—may press on the posterior tibial nerve and cause numb feelings. Nerve injury or compression can also occur in chronic conditions like knee osteoarthritis, where the damage over time may affect how the nerves send signals. It is important to know that numbness is a type of symptom that might need further check-up if it continues or worsens. Even though these explanations show some common causes, each case is different.
