The pain shoulder pain creates a lot of confusion partially because much of shoulder pain comes from either the frozen shoulder, or the rotator cuff. In the past few years there has been in the attempt to do surgery on rotator cuff repairs.
Rotator cuff repairs are is not as simple as it might seem because the tendon is liable to become old and atrophy. It would appear that a normal tendon has a relatively good period of good 30 years and then as we get older it naturally deteriorates and can tear and atrophy naturally with age. With careful evidence-based research shoulder surgery looks as though it is relatively useful and appropriate if you have a rotator cuff tear and you are below the age of 65. After the age of 65 rotator cuff tear is much more complex and challenging and there is a good chance 40 to 50% of the tendon will actually re tear with in 2 years. Which is why even if there has been trauma in the older age group they prefer to give you exercise treatment rather than surgery due
The simple understanding that biologically the tissues do not heal nearly so well in the older age group, there is more muscle atrophy and wasting so rehabilitation which takes a good year after surgery and requires a great deal of effort can be most frustrating and difficult in the older age group that is over 65 years.
Here is the sample of the current papers and lectures given out by Prof Jeremy Lewis, and the wonderful Jo Gibson
shoulder surgery is most successful in the younger age group who are fit active and will follow up a good quality rehabilitation programme
