Which graft is better for AC joint surgery in adults?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I got my AC joint separated while mountain biking. It is grade 5. I am getting surgery, and I want to know whether I should use an autograft (hamstring) or an allograft from a cadaver. I am very active in outdoor adventures and sports.

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I have read your query, and I am sorry to hear about your injury.

The good news is that there are many modalities available for AC joint injuries (acromioclavicular joint), which are showing promising results. Factors such as activity level, overall health, and aging can also influence recovery and treatment decisions.

Type five injuries constitute tears of the two important ligaments in the shoulder region, which are the coracoclavicular and acromioclavicular ligaments. This is associated with collar bone dislocation as well as muscle injury. A double ligament injury makes the AC joint unstable and needs surgical correction. The surgical options available are generally as follows.

  1. An open reduction internal fixation is done. In this procedure, the shoulder joint will be cut open, and the collar bone (clavicle) will be realigned. The torn ligaments will be reconstructed with either the patient's own local tissue or cadaveric ligaments (allografts).
  2. Both types of grafts have similar performance; however, the allografts are preferred. Because there is no donor site operation involved, they are of sufficient length to be looped around the coracoid joint and over the collar bone. In some patients, aging may slightly affect tissue healing capacity, making graft selection an important consideration.
  3. Autografts (hamstrings) are used only if a patient feels strongly against having a foreign object implanted in his or her body and is willing to accept the extra operation required to harvest the hamstring tendon.
  4. In your case, I would suggest you contact your doctor and have a detailed discussion with him before deciding on the type of graft that would suit your needs most.

I hope this helps.

Kindly revert in case of further queries.

Thank you.
