Insights
Polydioxanone sutures significantly reduce infection and improve outcomes in acute Achilles tendon rupture repair compared to polyester sutures. This study highlights absorbable sutures as a superior choice for better patient results.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Acute Achilles tendon rupture is a common injury requiring surgical repair.
- Suture material choice may influence post-operative outcomes and complication rates.
Purpose of the Study:
- To compare the efficacy of Polydioxanone (PDS) absorbable sutures versus Polyester (Ethibond) non-absorbable sutures in repairing acute Achilles tendon ruptures.
- To evaluate differences in infection rates and clinical outcomes (Boyden score) between the two suture groups.
Main Methods:
- Prospective study of 53 patients with acute Achilles tendon rupture over two years.
- Patients were divided into two groups based on suture material used for repair: PDS or Polyester.
- Outcomes including infection rate and Boyden score were assessed with a minimum six-month follow-up.
Main Results:
- The Polyester group had a significantly higher infection rate compared to the PDS group (p=0.001).
- 100% of patients in the PDS group achieved good/excellent results, versus 68.4% in the Polyester group.
- Patients receiving non-absorbable Ethibond sutures exhibited higher infection incidence and poorer Boyden scores.
Conclusions:
- Absorbable Polydioxanone sutures are associated with lower infection rates and superior clinical outcomes in acute Achilles tendon rupture repair.
- Polyester sutures may lead to increased complications and less favorable results in these patients.
Abstract:
We prospectively studied acute Achilles tendon rupture in patients over a two 2-year period and reviewed the causes, outcome and complications. There were 53 patients included with acute Achilles rupture with minimum follow up period of 6 months. We compared the outcomes including infection rate and Boyden score between the two groups repaired by Polydioxanone and Polyester respectively. All infected cases had a suture repair using the polyester suture. The difference in the infection rate was highly significant between the 2 groups (p=0.001). All 34 patients (100%) in the PDS group had good / excellent results based on the Boyden clinical assessment. Conversely, only 16 patients 9(68.4%) had good or excellent results IN Polyester repair group. Patients treated with a non- absorbable suture (ethibond) material for repair had a higher incidence infection and worse Boyden scores than the absorbable PDS group.
