Effect of Platelet-Rich Plasma Injection on the Treatment of Achilles Tendinopathy: A Systematic Review and Meta-analysis

Background

Achilles tendinopathy is a common condition without a reproducible and timely treatment modality. Platelet-rich plasma (PRP) injection has been proposed as an enticing treatment option, but there is no consensus regarding its effectiveness.

Purpose

To pool the available data and evaluate the evidence of the effect of PRP injections on Achilles tendinopathy.

Study Design

Systematic review; Level of evidence, 1.

Methods

This review was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. CINAHL via EBSCOhost, Cochrane Library, and PubMed databases were searched for randomized controlled trials comparing PRP injection with nonoperative treatment, with the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire score or maximal Achilles tendon (AT) thickness on ultrasound as outcome measures. Risk-of-bias assessment was performed of the included studies, and meta-analyses compared differences in outcome measures between PRP injection and control at the short-term (3-month), intermediate-term (6-month), and long-term (12-month) follow-ups.

Results

Of 409 publications, 6 publications (N = 422 patients with chronic midportion Achilles tendinopathy) were identified from the literature search. Risk-of-bias assessment revealed 2 studies were low risk, 1 was of some concern, and 3 were high risk of bias. Meta-analysis revealed no significant differences between PRP injection and control at any time point for both VISA-A score (short term: P = .29; intermediate term: P = .42; long term: P = .57) and maximal AT thickness (short term: P = .60; intermediate term: P = .20; long term: P = .55).

Conclusion

Our review demonstrated that although recent trends have shown an increasing popularity of PRP injection, no solid evidence has been established. The heterogenicity of the tendinopathy pathology and the PRP injection content and methodology should be controlled by better-designed clinical trials. Further research is needed before it should be recommended as a standard treatment.

Endoscopic Application of a Collagen Scaffold for Treatment of Achilles Tendinopathy

This technical note explores Achilles tendinopathy treatment, focusing on the endoscopic application of a bioinductive collagen scaffold, a different approach to this prevalent condition. Indications include symptoms of midportion Achilles tendinopathy that have not responded to nonsurgical treatment. A co-axial 2-portal Achilles tendoscopy using a 30° 4-mm arthroscope is performed with the patient in a prone position. The procedure involves standard Achilles tendoscopic debridement and adhesiolysis, followed by the scaffold's introduction through the proximal portal in a rolled-up state; this bioinductive collagen scaffold is then unfolded arthroscopically and on-laid over the tendinopathy site under tendoscopic visualization. The bioinductive scaffold is then anchored with soft-tissue anchors, after which the portal incision can be closed and the patient rehabilitated according to standard protocol. This technique is notable, as it negated the need for an open incision and instead uses endoscopy for the application of this collagen scaffold which can be a stand-alone treatment option for Achilles tendinopathy; or used in conjunction with other minimally invasive Achilles tendon treatment procedures such as an endoscopic flexor hallucis longus transfer.

The Top 100 Most Impactful Articles on the Achilles Tendon According to Altmetric Attention Score and Number of Citations

Background

Achilles tendon injuries often generate substantial discussion in the mainstream media. The Altmetric Attention Score (AAS) measures the online dialogue pertaining to Achilles tendon research that occurs outside scientific journals, which traditional citation-based metrics fail to capture.

Purpose

To characterize the top 100 most-cited Achilles tendon articles and compare them with the 100 Achilles tendon articles with the highest AAS. A secondary goal was to gain an improved understanding of the online dissemination and interpretation of Achilles tendon research through this comparison.

Study Design

Cross-sectional study.

Methods

The Web of Science Clarivate database was queried to isolate the 100 most-cited Achilles tendon articles, and the Altmetric database was queried to identify the Achilles tendon articles with the top 100 AAS values. Data elements were extracted for each article including study type, study topic, and geographic origin.

Results

The Web of Science Clarivate database search yielded 10,890 articles published between 1970 and 2021. The 100 most-cited articles were published in 35 journals, with the American Journal of Sports Medicine being the most prevalent. The mean (±SD) number of citations was 214.5 ± 86.47. The most prevalent study type was laboratory (28.0%). The most prevalent study topic was treatment (41.0%). Of these articles, 72.0% were European. The Altmetric database search yielded 3810 articles published between 1957 and 2021. The AAS of the top 100 articles ranged from 37 to 476 with a mean of 98.17 ± 85.53. The selected articles were published in 39 journals, with the British Journal of Sports Medicine being the most prevalent. The most prevalent study type was randomized controlled trial (25.0%). The most common study topic was treatment (40.0%). Of these articles, 46.0% were European.

Conclusion

Our findings suggest that, although the scientific community remains committed to high-impact journals with articles backed by high citation numbers, there is an increasing opportunity to consume Achilles tendon literature through social media.

Achilles Tendon Rupture: Mechanisms of Injury, Principles of Rehabilitation and Return to Play

The Achilles tendon is the thickest, strongest and largest tendon in the human body, but despite its size and tensile strength, it frequently gets injured. Achilles tendon ruptures (ATRs) mainly occur during sports activities, and their incidence has increased over the last few decades. Achilles tendon tears necessitate a prolonged recovery time, sometimes leaving long-term functional limitations. Treatment options include conservative treatment and surgical repair. There is no consensus on which is the best treatment for ATRs, and their management is still controversial. Limited scientific evidence is available for optimized rehabilitation regimen and on the course of recovery after ATRs. Furthermore, there are no universally accepted outcomes regarding the return to play (RTP) process. Therefore, the aim of this narrative review is to give an insight into the mechanism of injuries of an ATR, related principles of rehabilitation, and RTP.
