The anterior cruciate ligament (ACL) of the knee is frequently injured, but it has limited healing potential. Surgical reconstruction using soft tissue autografts is often required for active patients. However, about 20–25% of patients have less than satisfactory results and some even developed of osteoarthritis in the long-term. Thus, there is a need for alternative approaches. With advances in functional tissue engineering, healing of the ACL using growth factors and/or bioscaffolds has generated new clinical interests [1].

Ligament Tissue Engineering

Following anterior cruciate ligament injury, a mechanically stable tissue replacement is required for knee stability and to avoid subsequent damages. Tissue engineering of the anterior cruciate ligament demands a biocompatible scaffold with a controllable degradation profile to provide mechanical support for 3 to 6 months. It has been argued that embroidered textile scaffolds made of polylactic acid and poly(lactic-co-ɛ-caprolactone) fibres are a promising approach for the ligament tissue engineering with an adapted functionalization and cell seeding strategy. Therefore, the hydrolytic degradation behaviour of embroidered scaffolds made of polylactic acid and a combination of polylactic acid and poly(lactic-co-ɛ-caprolactone) fibres was investigated under physiological conditions for 168 days. The changes in the mechanical behaviour, the molecular weights as well as the surface structures were analysed. Sufficient mechanical properties comparable to native anterior cruciate ligament tissue could be demonstrated for scaffolds made of polylactic acid fibres after 6 months under hydrolysis. These results clarify the potential of using embroidered scaffolds for ligament tissue engineering.

Minimal Reduction

Introduction: One of the most frequent knee injuries and one that is on the increase, especially in sports, is the anterior cruciate ligament injury. Surgical reconstruction is essential to recover the biomechanics of the knee, provide correct stability and pain-free function, as well as toavoid early degenerative changes. The objective of the present study was to assess the functional recovery of patients undergoing reconstruction of the anterior cruciate ligament by means of ligamentoplasty with semitendinosus- internal rectus tendon and Toggelock system. Material and methods: A retrospective descriptive observational study was designed, which included 29 patients who underwent a ligamentoplasty with internal semitendinosus-rectum and Togglelock system in our Center, during the years 2017-2018. Variables obtained from the clinical history and the Lysholm scale were studied to assess the patients. Results: In total, a sample of 29 patients was obtained, 26 men and 3 women with a mean age of 31.13 years (range 19-53). The most frequently injured knee was the right knee in 17 patients out of 29, with 65% presenting associated injuries. One patient had suffered a tibial fracture operated with an intramedullary nail that altered the final results. The postsurgical score on the Lysholm subjective assessment scale was 86. The mobility of the operated knee showed a minimal reduction in flexion of 6º compared to the non-operated knee that was statistically significant. Conclusion: The results obtained after ACL reconstruction with this technique, using the semitendinosus- internal rectum plasty and the Togglelock system were good-excellent, with a high degree of patient satisfaction, few complications, and notable functional results.
