Biodegradable polyurethane urea fibers for ACL reconstruction have been produced by wet spinning. By using a short‐chain polyester diol as the soft segment in the polyurethane urea the elongation‐to‐break of the fibers have been reduced to be below 100% instead of 400–800% for spandex fibers, the modulus is increased from 5 MPa to 1 GPa and the tensile strength is increased from 0.1 N/tex to 0.4 N/tex. The composition of the polyester determines at which rate the fiber degrade. Different polyesters have been investigated to find the most suitable degradation rate for ACL application.
