A paper (1) was published in the American Journal of Sports Medicine describing tennis shoulder as more than just a shoulder pain but as a chronic problem that could eventually lead to spine problems. This is what those researchers of nearly 50 years ago wrote: “(A) depression (droopy, slopped) of the exercised shoulder was found in skilled tennis players, and in other athletes employing the overhand motion. The deformity is attributed to stretching of the shoulder elevating muscles and hypertrophy of the extremity. Most symptoms were over the anterior (front) rotator cuff, and occurred on abduction of the arm. Shoulder depression results in a relative abduction and abduction causes impingement of the cuff. Shoulder droop may induce thoracic outlet syndrome and may simulate scoliosis in the athlete.”

Over the years I have seen many athletes who have shoulder problems. Quite a few were tennis players. For most of these tennis players, their problems were that of the rotator cuff, the previously mentioned problems of impingement and unfortunately a lot of shoulder pain. For some, their shoulder pain extended into their neck. For others the problems of a droopy shoulder or one shoulder lower than the other was causing them significant back problems. But the problems can go even further.

Forty-four years later, an October 2020 paper (2) extended the list of problems that shoulder injuries could play part in and extended these problems to that of the elbow and wrist: “Common injuries include internal shoulder impingement, rotator cuff pathology, labral tears, elbow tendinopathies, as well as extensor carpi ulnaris tendinopathies and subluxation Problems in the wrist). Posterior shoulder instability, distal humeral bone stress (at the elbow), elbow medial collateral ligament, and nondominant wrist ulnar collateral ligament injuries are not commonly reported injuries, but they are of significant clinical importance (in tennis players).

A point that should be made here is that for some people their shoulder problems are much more advanced than simple treatments to help.

Treatment for Tennis Shoulder Injuries

Activity Modification

A top treatment for tennis shoulder is also one of the most unpopular treatments. The treatment is called Activity Modification. Activity Modification simply means that you have stopped playing tennis or you are playing less frequently. Many people do try resting the shoulder. For many people this works very well and they are able to resume playing at their previous levels. For other however, rest was “only a waste of time.” As soon as these people felt that they have rested their shoulder long enough, they returned to the court. Once they did they found that the pain came back immediately or soon after they resumed playing. They were back to square one.

Non-steroidal Anti-inflammatory Medications (NSAIDs)

For many people NSAIDS can make their shoulders feel better in the short-term. However, higher doses maybe needed in the long-term to achieve similar results. In a September 2019 study (3) doctors compared ibuprofen and acetaminophen in patients with shoulder pain. In both groups (ibuprofen and acetaminophen), there was significant variability in response to these medications. Even if the average pain score was improved, several patients exhibited worsening of their condition. . .However, the answer to the question of which medication provided more benefit to the patients remained elusive. Ibuprofen appeared to treat the issues related directly to the perception of pain and, consequently, the function of upper extremities better, whereas acetaminophen administration resulted in better indices for Quality of Life.

Physical Therapy

People who play tennis are frequently diagnosed with rotator cuff tendinopathy. I frequently see patients with an MRI of a shoulder tendon tear or an MRI of a problem of chronic tendinopathy. Tendinopathy is a more recent term to describe a chronic pathology of a tendon that causes shoulder pain. The problem of Tendinopathy can be divided into two broad categories:

  • Tendinitis means inflammation of the shoulder tendons. This is the characteristic swelling that comes with a worsening wear and tear or acute injury.
  • Tendinosis is the “old, nagging injury.” The tendon is injured but the body has given up trying to heal it. It is an injury without inflammation. Why did the body give up? In some of the people we see, it comes as the result of a long and extensive anti-inflammatory or cortisone treatment history.

Many people have had successful physical therapy for treating rotator cuff tendinitis, tendinosis, and shoulder impingement syndrome. The idea of course being the avoidance of movement that causes pain and postural adjustments in the workplace setting to help avoid having the shoulders roll in or sloop.

Physical therapy may be less effective or not work at all in situations where the shoulder tendons are stretched or damaged enough that they cannot provide the resistance needed to strengthen the muscles.

Tennis Shoulder Tendinopathy and Shoulder Impingement Treatment

Many people continue to play tennis through their pain. They complain about pain at the top of their shoulder, the side of their shoulder and when they extended their hands over their head during the serve. If you have chronic shoulder pain affecting your game you have probably tried remedies and exercises listed above including RICE (rest, ice, compression, and elevation) and self-medicating with anti-inflammatory medications that may have helped short-term, but did not help you play long-term.

When you got to the point where you may have to stop playing, this is when you decided to get medical care. Medical care may not have been to your likening. You may have not liked the suggest your doctor gave you to stop playing for a while to see if your shoulder heals on its own. You may have liked it worse when after a long bout of rest, you picked up a racquet and the same pain remained.

When you returned to your doctor after the rest period and want to try something else to help accelerate your healing, as mentioned above, you may have been told to go to physical therapy to see if that works. You can also try a cortisone injection.

Treatment for shoulder pain

In our practice, Stem Cell Therapy is a treatment for musculoskeletal disorders. We treat degenerative joint disease, degenerative disc disease of the spine, and tendon and ligament injury. We offer stem cells drawn from patient’s own bone marrow. Stem cells are “de-differentiated pluripotent” cells, which means that they continue to divide to create more stem cells; these eventually “morph” into the tissue needing repair — for our purposes, collagen, bone, and cartilage.

Bone Marrow aspirated stem cells injected into the shoulder

In our research which appears in the peer-reviewed journal Cogent Medicine. The study can be found here in its entirety: Treatment of shoulder osteoarthritis and rotator cuff tears with bone marrow concentrate and whole bone marrow injections with a June 20, 2019 publication date.

Here we were able to demonstrate that:

  • Patients with rotator cuff tendinopathy and degenerative shoulder disease would benefit from either one and two stem cell treatments. Patients reported significant improvements in resting pain, active pain, and functionality score when compared to baseline.
  • These groups also experienced a 42.25% and 50.17% overall improvement respectively.
  • The group that received two treatments experienced statistically significant improvements in active pain when compared to the group that received one injection.
  • There were no significant outcome differences between rotator cuff tear and osteoarthritis patients.

Conclusions: Our study demonstrated that patients diagnosed with shoulder osteoarthritis or rotator cuff tears experienced symptomatic improvements in pain and functionality when injected with bone marrow concentrate (BMC) or whole bone marrow (WBM). Further randomized control studies are needed to validate these findings.
