Endoscopic treatment of insertional Achilles tendinopathy: A cadaver feasibility study

Endoscopic calcaneal SpeedBridge technique: Decreased postoperative complication rate in insertional achilles tendinopathy

BACKGROUND

An endoscopic calcaneal SpeedBridge technique was described recently. The primary objective of this study was to report the postoperative complications seen with calcaneal SpeedBridge repair. The secondary objective was to report short- and medium-term functional outcomes.

HYPOTHESIS

Postoperative complications are less common with endoscopic vs. open SpeedBridge suturing.

MATERIAL AND METHODS

The endoscopic SpeedBridge technique was used in 9 patients who had insertional Achilles tendinopathy refractory to conservative management. The patients were evaluated at least 24 months after the procedure. Infectious and wound-healing complications were recorded. Visual analogue scale (VAS) scores for pain and patient satisfaction, shoeing difficulties, the European Foot and Ankle Society (EFAS) score, and the Victorian Institute of Sport Assessment-Achilles (VISA-A) score were assessed.

RESULTS

During the mean follow-up of 25.3 months, no complications were recorded. The EFAS and VISA-A scores were 37/40 and 91/100, respectively. The mean VAS scores for pain and satisfaction were 1.7/10 and 9.3/10, respectively. No patients reported shoeing difficulties.

CONCLUSION

Endoscopic calcaneal SpeedBridge suturing is associated with a lower complication rate compared to the open variant. Clinical outcomes are highly satisfactory in the short and middle terms.

Minimally invasive surgeries for insertional Achilles tendinopathy: A commentary review

Studies of minimally invasive surgery for insertional Achilles tendinopathy are limited. To establish this surgery, the following techniques must be minimally invasive: Exostosis resection at the Achilles tendon insertion, debridement of degenerated Achilles tendon, reattachment using anchors or augmentation using flexor hallucis longus (FHL) tendon transfer, and excision of the posterosuperior calcaneal prominence. Studies on these four perspectives were reviewed to establish minimally invasive surgery for insertional Achilles tendinopathy. Techniques for exostosis resection were demonstrated in one case study, where blunt dissection around the exostosis was performed, and the exostosis was resected using an abrasion burr under fluoroscopic guidance. Techniques for debridement of degenerated Achilles tendon were demonstrated in the same case study, where the space left after resection of the exostosis was used as an endoscopic working space, and the degenerated Achilles tendon and intra-tendinous calcification were debrided endoscopically. Achilles tendon reattachment techniques using suture anchors have been demonstrated in several studies. However, there are no studies on FHL tendon transfer techniques for Achilles tendon reattachment. In contrast, endoscopic posterosuperior calcaneal prominence resection is already established. Additionally, studies on ultrasound-guided surgeries and percutaneous dorsal wedge calcaneal osteotomy as minimally invasive surgery were reviewed.

Lateral approach for insertional Achilles tendinitis with Haglund deformity

Objective

The study aims to investigate the functional outcome of the lateral approach for insertional Achilles tendinitis (IAT) with Haglund deformity.

Methods

From January 2016 to September 2019, 14 cases of IAT with Haglund deformity that resisted conservative treatment received surgery in our department. A lateral approach was used to debride the bony and soft tissue and reattach the insertion of the Achilles tendon. The Visual Analog Scale (VAS), American Orthopedic Foot and Ankle Score (AOFAS), and Victorian Institute of Sport Tendon Study Group-Achilles Tendinopathy score (VISA-A) were used to evaluate clinical outcomes.

Result

The mean patient age was 39.57 years at the time of surgery. The mean follow-up was 14.74 months. The mean VAS score significantly decreased from 4.86 ± 0.86 preoperatively to 1.21 ± 1.58 postoperatively (P < 0.001). The mean AOFAS score significantly improved from 66.64 ± 6.23 preoperatively to 90.21 ± 11.50 postoperatively (P < 0.001). The mean preoperative and the last follow-up VISA-A were 66 (range 56.75-69.25) and 86 (range 75.75-97.00) points, respectively (P < 0.05).

Conclusion

The lateral approach was effective and safe for IAT with Haglund deformity. Moreover, the mid-term functional outcome was promising.
