How to Diagnose a PLC Injury
Dr. Boykin will conduct a thorough history and examination of the knee checking for pain, mobility, instability, and strength. He will assess all ligaments of the knee on exam to determine the extent of injury. X-rays will be taken to look for any injury to the bone and in certain cases specialized stress X-rays be performed on both knees to compare stability. A MRI scan is usually ordered to better visualize the damage to each of the components of the PLC and also to assess the status of the meniscus and articular cartilage of the knee.
Treatment Options for a PLC Knee Injury
In certain cases where the PLC suffers a “sprain” or a minor tear the injury may be able to be treated with non-operative measures. These include rest, icing, appropriate bracing, physical therapy, and strengthening of the muscles around the knee. If there is a complete tear of the PLC with resultant instability on exam and X-rays, for patients who have failed non-operative treatment, and in cases of multiligament injury that include the PLC, a surgery will be recommended.
When to Have Surgery for PLC Knee Injury
For severe injuries to the PLC, Dr. Boykin will perform an open reconstruction procedure to rebuild or repair each component of the PLC. Dr. Boykin strongly feels that is important to address each of the three parts of the PLC if they are injured and to reconstruct them back to their original anatomy. During this complex procedure donated grafts will be used to perform the reconstruction. Any other procedures that need to be performed (including repair of the meniscus or reconstruction of other ligaments) are typically performed at the same surgery when possible. In cases where a patient has had insufficiency of the PLC for many years or has failed another PLC surgery because of a malalignment problem of the leg, Dr. Boykin will perform a staged procedure to correct the alignment of the leg followed by a ligament reconstruction.
