Anterior cruciate reconstruction using a Dacron ligament prosthesis. A long-term study

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomaterials Science

Background:

• Chronic anterior cruciate ligament (ACL) insufficiency often requires surgical reconstruction.
• Prosthetic graft materials are explored as alternatives to autografts or allografts.
• Long-term outcomes of synthetic ligament prostheses require thorough investigation.

Purpose of the Study:

• To evaluate the efficacy and long-term outcomes of Dacron ligament prosthesis for ACL reconstruction.
• To determine the failure rate and identify factors associated with poor outcomes.
• To assess changes in patient performance and laxity over time.

Main Methods:

• A prospective, single-center study involving 35 patients with chronic ACL insufficiency.
• All patients underwent ACL reconstruction using a Dacron ligament prosthesis by a single surgeon.
• Follow-up averaged 50 months, with failure defined by clinical laxity, instrumented laxity, or arthroscopic findings.

Main Results:

• An overall failure rate of 37.1% (13/35 patients) was observed.
• The failure rate was higher in the 'salvage' group (78%) compared to isolated ACL insufficiency (23%).
• Initial improvements in laxity, Lysholm, and Tegner scores were noted at 2 years, followed by performance deterioration.

Conclusions:

• Dacron ligament prosthesis for ACL reconstruction is associated with a high failure rate.
• Outcomes appear worse in patients requiring revision or with multiple instabilities.
• The long-term durability and functional performance of this synthetic graft are questionable, showing late deterioration.
