Platelet Rich Plasma Therapy For Frozen shoulder – Adhesive
capsulitis

Marc Darrow MD,JD

Clinically we have seen many patients with various and diverse shoulder problems. One such problem is the problem of frozen shoulder. We have had patients improve with PRP treatments for their frozen shoulder by having less pain, greater flexibility, and for some the benefit of accelerated recovery as they had been told previously by other doctors that recovery could take up to two years. PRP can help many people with frozen shoulder. It won’t help everyone. A consultation and examination will offer the best assessment for the success of the treatment.

A January 2021 (1) study confirmed similar results to what we see in our office. Improvement in frozen shoulder.

This was triple blind study, the doctors did not know what they were injecting, the patients didn’t know what they were being inject with and the researcher analysis did not know what treatment offer the results they were examining.

  • Methods: 32 adult patients with adhesive capsulitis (21 female, 11 male with an average age of 57, ranging from 23 to 70) were included in this study.
  • Patients had to have shoulder pain and restrictions in movements (at least 25% when compared to the other side, and at least in two directions) for three months minimum and nine months maximum.
  • Patients were randomized to two groups, and one group took PRP injections for three times every two weeks, while the other group took saline injections in same frequency and volume.
  • A standardized exercise program was also applied to all patients.
  • Patients were evaluated with Shoulder Pain and Disability Index (SPADI), Visual Analogue Scales for pain and disability, ranges of movements, and use of analgesics in before, after, and third month after the initiation of the therapy.

Results: Baseline comparisons between groups showed no differences.

  • Shoulder Pain and Disability Index  and ranges of motion in all directions showed significant improvements with therapy, and the group which took PRP injections showed better improvements when compared to the control group. Visual Analogue Scale was found to be better for the PRP group after therapy and third month, and not for the control group. Use of analgesics was not found to be significant for both groups.

Conclusion: PRP injections were found to be effective in both pain and disability, and showed improvements in a restricted shoulder due to adhesive capsulitis. These findings might point out PRP as a therapeutic option in the management of adhesive capsulitis.

A December 2020 study (2) evaluated the effect of ultrasound guided injection of PRP into the shoulder joint in patients with adhesive capsulitis  and compared its effect with that of conventional physiotherapy

  • Methods: Sixty-four subjects with adhesive capsulitis were included and randomly allocated into two groups, as follows:
    • PRP (32 patients) : Conservative physical therapy (CPT); short wave diathermy and exercise therapy were performed at three sessions/week for 6 weeks).
    • Treatment outcomes evaluated therapeutic effectiveness before and at 1, 3, and 6 weeks after PRP injection and CPT initiation.

Results: Subjects in both groups showed a significant decrease in the visual analogue scale score for pain and shoulder and hand scores, and they a significant increase in shoulder passive range of motion at all evaluation time points. There was no significant difference in the measured outcomes between the two groups. However, there was less acetaminophen consumption after PRP injection compared with that after conservative physical therapy.

Prior to this research there was very limited studies. In fact a search of the medical literature shows two case histories. Both are discussed below.

One case history was published in the publication The archives of bone and joint surgery (3). It describes the situation and treatment of frozen shoulder in a 45-year-old-man.

“Platelet-rich plasma can produce collagen and growth factors, which increases stem cells and consequently enhances the healing. To date, there is no evidence regarding the effectiveness of platelet-rich plasma in frozen shoulder. A 45-year-old man with shoulder adhesive capsulitis volunteered for this treatment. He underwent two consecutive platelet-rich plasma injections at the seventh and eighth month after initiation of symptoms. We measured pain, function, range of motion by the visual analogue scale (VAS), scores from the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and goniometer (to measure improvement in arm angles); respectively.

After first injection, the patient reported 60% improvement regarding diurnal (during the day) shoulder pain, and no night pain. Also, two-fold improvement for ROM and more than 70% improvement for function were reported. This study suggests the use of platelet-rich plasma in frozen shoulder to be tested in randomized trials.”

A published case history from 2020 (4) describes how PRP helped a patient with her adhesive capsulitis brought on by chronic kidney disease. (A point here, we do not treat kindney disease, this case history is about the patient’s frozen shoulder treatment with PRP). Here is the case:

“Adhesive capsulitis is a common problem in patients with chronic kidney disease. Patients suffer from joint stiffness and painful joint movement. Conservative treatments consist non-steroid anti-inflamatory drugs, intraarticular injections and physical therapy. Newer approaches such as platelet-rich plasma injections (PRP) also can be applied but there is little evidence for the effectiveness of PRP in patients with adhesive capsulitis.

A 70 year-old woman, receives dialysis treatment admitted to our out-patient clinic with stiffness and pain in her right shoulder. Her diagnosis was confirmed with MRI as adhesive capsulitis. PRP injection began to be applied as planned; 3 times, 15 days between each injection.

At the last assessment average ROM increased on flexor, abductor and internal rotator sides.” The patient did not however note pain improvement.

In this case the patient noted improvement in range of motion. The study was on three single injections spaced 15 days apart. It may be possible that the patient would have had pain improvement and increased range of motion with further treatment.

We have had patients improve with PRP treatments for their frozen shoulder by having less pain, greater flexibility, and for some the benefit of accelerated recovery as they had been told previously by other doctors that recovery could take up to two years. PRP can help many people with frozen shoulder. It won’t help everyone. A consultation and examination will offer the best assessment for the success of the treatment.
