A Preclinical Model to Study the Influence of Graft Force on the Healing of the Anterior Cruciate Ligament Graft

In conclusion, we have developed a novel ACL reconstruction model that can reproducibly produce two ACL graft force patterns. This model would permit further research on how ACL graft forces may affect subsequent graft healing, maturation, and function.

Surgical repair of tendons of the foot and ankle is performed utilizing various methods, including autografts, allografts, and synthetic grafts. Artelon is a synthetic biomaterial that is fabricated from wet-spun fibers of PCL-based polyurethane urea, and has, optimal mechanical properties compared with other grafting options. Because of excellent results of Artelon in ACL reconstruction, its use was explored in 3 foot and ankle cases: repair of Achilles, posterior tibial, and peroneal tendons. Artelon has proven to be a successful alternative for tendon repairs, with all 3 cases returning to full function within 8 to 16 &...

Objective: We aimed to quantitatively assess the outcomes of studies, comparing the use of Bone-patellar tendon-bone (BPTB) and the quadriceps tendon-bone (QTB) autografts when reconstructing the anterior cruciate ligament (ACL). Data Sources: MEDLINE, Embase, and CINAHL databases were searched for relevant articles published between January 1980 and January 2015 for the purpose of identifying studies comparing BPTB and QTB autografts for ACL reconstruction. Included studies were assessed regarding their methodological quality before analysis. Outcomes analyzed were graft failure rates, objective and subjective stabil...

Soft tissue allograft augmentation of small hamstring autografts, so-called hybrid grafts, has been proposed as an option during anterior cruciate ligament reconstruction (ACL-R). However, notable concerns exist with both small autograft use and allograft use during ACL-R, particularly in young, active patients. We currently choose to augment hamstring autografts with diameters

Publication date: Available online 30 April 2018 Source:Arthroscopy Techniques Author(s): Naser M. Selim An untreated posterolateral corner (PLC) injury in patients with a torn anterior cruciate ligament (ACL) may be a leading cause of ACL reconstruction failure. Combined ACL and PLC reconstruction is discussed in few studies in the literature. Femoral tunnel intersection in combined reconstruction has been reported to be high. Short grafts may render combined reconstruction undoable. This technical note describes a technique that allows a combined ACL and PLC reconstruction. The ACL graft is a 4-stranded hamstring tendon...

ConclusionsBone-to-bone integration on the femoral and tibial sides was complete within 5  months after surgery in all cases. Since the time required for bone integration is important in designing the postoperative rehabilitation approach, these results will serve as a useful guideline for planning rehabilitation protocols.Level of evidenceIV.

The goal of this study is to investigate the biomechanical and histological properties of in vivo heterotopically prefabricated cruciate ligament replacement grafts with and without mechanical stimulation. The clinical goal is to heterotopically prefabricate a bone –tendon–bone graft for anterior cruciate ligament reconstruction, which allows rapid ingrowth and early full weight bearing.
