Chicago, USA: Achilles tendinopathy is a significant cause of disability among adults. Among these tendinopathy cases, 4-23% will also have concurrent partial tendon tears. Current conservative treatment modalities include analgesics, rest, orthotics, and physical therapy including eccentric exercise for tendinopathy. When non-invasive treatments fail, injectional therapy with saline, analgesics, or corticosteroid have been considered. However, there is a lack of established efficacy for conservative treatment modalities as evidenced by the wide range of reported success in literature, ranging from 24% to 89%. Furthermore, corticosteroids should be generally avoided as they may increase the risk of injury, atrophy, and decrease tendon strength.

The study by M.J. Chin and K. La Violette investigated the alternative use of amniotic membrane/umbilical cord particulate (AMUC) injection in patients with Achilles tendinopathy with or without partial tendon tear.

A single-center, retrospective study was conducted on Achilles tendinopathy patients with or without a partial tendon tear and received AMUC injection. Pain was evaluated before and after treatment, and measured on an 11-point numerical rating scale, where 0 was no pain and 10 was worst imaginable pain. Usage of pain medication and complications was also reported.

Results:

• Ten Achilles tendinopathy patients (aged 61.3 ± 11.3 years) with (n=3) or without (n=7) partial tendon tear were included in the analysis.

• The cohort's average baseline pain score was 4.8 ± 1.2 despite the majority (n=9) of patients receiving prior conservative treatment over a duration of 78.3 ± 77.6 days.

• After AMUC injection, the pain significantly decreased to 1.7 ± 1.9 at 1 month and 1.1 ± 1.4 at 3-months (p<0.01) post-treatment.

• Four patients who had previously used narcotic pain medication discontinued use within 3-months after treatment.

• There were no treatment-related complications.

The authors concluded that the use of injectable AMUC may safely provide pain relief in Achilles tendinopathy patients with or without partial tendon tear. Additional comparative studies with larger treatment groups are warranted to validate these findings.
