Type of tendinopathy treated and study outcomes
| Author(s) (Year) | No. of Cases Included | Demographics | Tendinopathy Treated | Outcomes |
|---|---|---|---|---|
| Barnes et al (2015)4 | 19 | • Average age, 55.3 y • 10 male, 9 female • Median duration of symptoms, >6 mo |
Lateral and medial epicondylitis of the elbow | Baseline VAS improved from 6.4 to 0.7 at 1 y, majority of improvement occurring in the first 3 months. Q-DASH score improved from 44.1 to 8.6 at 1 year. MEPS improved from 59.1 to 90.5 at 1 year. |
| Battista et al (2018)6 | 7 | • Mean duration of symptoms, 21.4 mo | Lateral epicondylitis of the elbow | Preoperative VAS score was 7.9 and decreased to 1.1 postoperatively at 2 y. Preoperative ASES score was 55.6 and at 1 y it was 93.4. One of 7 patients underwent open tendon debridement after failure of symptom relief. |
| Boden et al (2019)8 | 30 | • Mean age, 51 y • 40% female • On average experience, 25 mo of pain prior to intervention |
Medial and lateral epicondylitis of the elbow | 80% of Tenex patients were satisfied vs 79% of PRP patients; 16% of PRP patients and 20% of Tenex patients had refractory pain requiring further procedures. No statistical difference in outcomes between PRP and Tenex. |
| Chimenti et al (2019)12 | 34 | • Median duration of symptoms, 1.5 y • Mean age, 52.2 y • Mean BMI, 32.9 kg/m2 • 21 female, 13 male |
Insertional Achilles tendinopathy | At long-term follow-up, 4 of 34 had no pain, 13 had mild pain, 2 had moderate pain, 1 had worse pain, and rest were lost to follow-up. Physical component of SF-12 improved but no change in mental component at short-term (6- or 12-week) follow-up. Complications: 1 superficial skin infection that resolved with oral antibiotics. |
| Koh et al (2013)25 | 20 | • Average age, 45.5 y • 7 male, 13 female • Median duration of symptoms, 12.5 mo • 17/20 had repetitive strain injury, 4 had sporting injury, 3 had history of trauma |
Lateral epicondylitis of the elbow | Median VAS score decreased from 5.5 at baseline to 0.5 at 1 year. Median DASH-Compulsory score dropped from 21.7 to 2.5 at 1 y and DASH-Work went from 25.0 to 0. 19 of 20 were satisfied and 1 neutral. 19 of 20 had reduction in extensor tendon thickness at 6 mo, 1 had increased thickness. |
| Patel (2015)39 | 12 | • Median duration of symptoms, >6 mo • 4/12 had endoscopic or open partial releases at other institutions |
Plantar fasciitis | Mean preoperative AOFAS score improved from 30.1 to 88.1 by 3 mo and sustained at 12 mo. No treatment complications noted. |
| Seng et al (2016)45 | 20 | • 7 male, 13 female • Average age, 45.5 y |
Lateral epicondylitis of the elbow | DASH-Compulsory score decreased to a median of 0. Tendon hypervascularity decreased in 94% and tendon thickness reduction in 100%. |
