More advanced techniques help patients resume a wider range of activities after rehabilitation.This first knee pain diagnosis chart focuses on pain at the front of the knee. Surgical procedures to repair posterior cruciate ligaments continue to improve. The benefits of less invasive techniques include less pain from surgery and quicker recovery times. Arthroscopic surgery is less invasive than traditional open surgery. Surgery to rebuild a posterior cruciate ligament is typically performed with an arthroscope using small incisions however, some surgeons will still make an additional incision on the side of the knee. It can take several months for the graft to heal into your bone. This graft is most often taken from another part of your body, or from another human donor (cadaver). Your doctor will replace your torn ligament with a tissue graft. Because sewing the ligament ends back together does not usually heal, a torn posterior cruciate ligament is typically reconstructed, or rebuilt. Additionally, patients with an isolated PCL tear may benefit from reconstruction if they have persistent instability or pain that is not improving with non-operative treatment. For example, if you have dislocated your knee and torn multiple ligaments including the posterior cruciate ligament, surgery is almost always necessary. Your doctor may recommend surgery if you have combined injuries.
Strengthening the muscles in the front of your thigh (quadriceps) has been shown to be a key factor in a successful recovery. Specific exercises will restore function to your knee and strengthen the leg muscles that support it. As the swelling goes down, you will start a careful rehabilitation program. To further protect your knee, you may be given crutches to keep you from putting weight on your leg. Your doctor may recommend a special brace to prevent the tibia bone from sagging backward (gravity tends to pull the bone backward when you are lying down). When you are first injured, the RICE method - rest, ice, gentle compression, and elevation - can help speed your recovery. Your doctor may recommend nonsurgical treatment options: If you have injured only your posterior cruciate ligament, your injury may heal quite well without surgery. Magnetic resonance imaging (MRI). MRI scans create better images of soft tissues, like the posterior cruciate ligament, than X-rays. Your doctor may also order stress views, in which the doctor can assess just how far back the shin bone can move. Although they will not show any injury to your posterior cruciate ligament, X-rays can show whether the ligament tore off a piece of bone when it was injured. It is possible, however, for these images to appear normal, especially if the injury occurred more than 3 months before the tests. Other tests that may help your doctor confirm your diagnosis include X-rays and magnetic resonance imaging (MRI) scans. It might slide backwards too far, particularly when it is bent beyond a 90-degree angle. Your injured knee may appear to sag backwards when bent. Physical examinationĭuring the physical examination, your doctor will check all the structures of your injured knee, and compare them to your non-injured knee. During your first visit, your doctor will talk to you about your symptoms and medical history.
