(PCL Tear)

 

Diagnosis

You will be asked about your symptoms and medical history. A physical exam will be done.
Images may need to be taken of the internal structure of your knee. This can be done with:
Ligament sprains are graded according to their severity:
  • Grade 1—Mild ligament damage.
  • Grade 2—Partial tearing of the ligament.
  • Grade 3—Complete tearing of the ligament.
 

Treatment

Talk with your doctor about the best treatment plan for you. Recovery time ranges depending on the grade of your injury. Treatment steps may include:

Acute Care

Rest
Your ligament will need time to heal. Avoid activities that place extra stress on the knee:
  • Do not do activities that cause pain. This includes running, jumping, and weight lifting using the legs.
  • Do not play sports until your doctor has said it is safe to do so.
Your doctor may recommend a knee brace to stabilize the knee, and crutches to keep extra weight off your leg.
Cold
To reduce pain and swelling, apply an ice pack to the area for 15-20 minutes, four times a day, for several days after the injury. Do not apply the ice directly to your skin. Wrap the ice pack in a towel.
Pain Relief Medications
To manage pain, your doctor may advise:
  • Over-the-counter medication, such as ibuprofen and naproxen
  • Topical pain medication—creams or patches that are applied to the skin
  • Prescription pain relievers
Compression
Compression can help prevent more swelling. Your doctor may recommend an elastic compression bandage around your knee. Be careful not to wrap the bandage too tight.
Elevation
Elevation can also help keep swelling down. Keep your knee higher than your heart as much as possible for the first 24 hours or so. A couple of days of elevation might be recommended for severe sprains.

Recovery Steps

Physical Therapy
Your doctor may refer you to a physical therapist. Therapy can help control discomfort and promote recovery.
Heat
Use heat only when you are returning to physical activity. Heat may then be used before stretching or getting ready to play sports to help loosen the ligament.
Stretching
When the acute pain is gone, start gentle stretching as recommended. Stay within pain limits. Hold each stretch for about 10 seconds and repeat six times. Stretch several times a day.
Strengthening
Begin strengthening exercises for your ligaments as recommended.

Surgery

Surgery may be needed to fully restore function of the knee. The decision to have surgery should be made after discussion with your doctor about your athletic needs, age, and associated factors.
