“…Other studies that compared four-stranded hamstring grafts to BPTB autografts showed similar stability and functional results [18,20]. Some authors concluded that given the high rates of kneeling pain, anterior knee pain and patellofemoral pain, BPTB autografts should be avoided in patients whose occupation or lifestyle requires frequent kneeling [21,23]. The responses to our survey revealed that hamstring tendon grafting is more popular than the traditional BPTB grafting, and more so outside of the United States.…”

“…An ideal ACL graft is one that is easily harvested, results in little harvest site morbidity, is biomechanically comparable to the native ligament, can be secured predictably and rapidly incorporates to the bones [23]. Most surgeons reportedly prefer autograft over allograft for ACL reconstruction: the use of allograft for ACL reconstruction has gained increasing popularity and is now estimated to be used in 20-30 % of primary reconstructions in the USA [3,9].…”

“…Hamstring grafting also allows separation of the graft to perform double-bundle reconstruction, which BPTB grafting does not [1]. On the other hand, a BPTB graft has an excellent initial fixation and improved graft incorporation related to bone-to-bone healing [16,20], but its use may also be associated with patellofemoral pain and (rarely) patellar fractures [23].…”

“…The use of a transtibial portal for femoral tunnel drilling may limit the surgeon's ability to achieve anatomic position and result in an anterior/superior femoral tunnel starting point [1,4]. The tibial tunnel can be modified (modified transtibial technique) and moved medially to avoid vertical femoral tunnels [23]; but even then, when the femoral tunnel is accurately placed, the tibial tunnel may be compromised and placed too posteriorly, resulting in a vertical graft on the sagittal plane [6]. The use of an arthroscopic AMP for femoral drilling, with the knee in hyperflexion, allows a more accurate posterior and horizontal placement of the femoral tunnel by keeping any bony structures from limiting the drills and allowing the two tunnels (tibial and femoral) to be placed independently [1,4,19].…”

“…Historically, ACL reconstructions were performed using bone-patellar-tendon-bone (BPTB) autografts fixed with metal interference screws (IS). BPTB autografts have been considered the gold standard to which other technologies are compared [3,20,23]. The goals of ACL reconstruction are to restore knee stability, prevent further damage to knee structures and improve functional outcome.…”

Purpose Bone-patellar-tendon-bone (BPTB) autografting fixed with metal interference screws (IS) is the gold standard for anterior cruciate ligament (ACL) reconstruction. Advances in surgical technology provide a wide choice of grafts, fixation devices and surgical approaches. Methods Two-hundred and sixty-one orthopedic surgeons of ten subspecialties from 57 countries were surveyed on their choice of graft and fixation device, the number of reconstructed bundles, and arthroscopic portal. Their preferences were analyzed according to country of origin, field of expertise and seniority, and compared to current publications. Results Hamstring autografting was the most popular choice (63 %), then BPTB (26 %) and allograft (11 %). The anteromedial portal was preferred over the traditional transtibial portal (68 % versus 31 %). Two-thirds reported routinely performing a single-bundle graft reconstruction, compared to one-third who used the double-bundle technique. The Endo-button was the most common graft fixation method (40 %), followed by the bioabsorbable IS (34 %), metallic IS (12 %), rigidfix (10 %) and others (4 %). The preferences of hamstring tendon grafting and the anteromedial portal are not supported in the literature. Responses from North American and European surgeons were different from all the others.Conclusions Surgeon preferences in ACL reconstruction differ considerably worldwide. Common practice is not always supported by evidence-based publications.

Emerging Biofabrication Strategies for Engineering Complex Tissue Constructs

et al. 2017

The demand for organ transplantation and repair, coupled with a shortage of available donors, poses an urgent clinical need for the development of innovative treatment strategies for long-term repair and regeneration of injured or diseased tissues and organs. Bioengineering organs, by growing patient-derived cells in biomaterial scaffolds in the presence of pertinent physicochemical signals, provides a promising solution to meet this demand. However, recapitulating the structural and cytoarchitectural complexities of native tissues in vitro remains a significant challenge to be addressed. Through tremendous efforts over the past decade, several innovative biofabrication strategies have been developed to overcome these challenges. This review highlights recent work on emerging three-dimensional bioprinting and textile techniques, compares the advantages and shortcomings of these approaches, outlines the use of common biomaterials and advanced hybrid scaffolds, and describes several design considerations including the structural, physical, biological, and economical parameters that are crucial for the fabrication of functional, complex, engineered tissues. Finally, the applications of these biofabrication strategies in neural, skin, connective, and muscle tissue engineering are explored.

A biodegradable tri-component graft for anterior cruciate ligament reconstruction

Bone-patellar tendon-bone (BPTB) autografts are the gold standard for anterior cruciate ligament (ACL) reconstruction because the bony ends allow for superior healing and anchoring through bone-to-bone regeneration. However, the disadvantages of BPTB grafts include donor site morbidity and patellar rupture. In order to incorporate bone-to-bone healing without the risks associated with harvesting autogenous tissue, a biodegradable and synthetic tri-component graft was fabricated, consisting of porous poly(1,8-octanediol-co-citric acid)-hydroxyapatite nanocomposites (POC-HA) and poly(l-lactide) (PLL) braids. All regions of the tri-component graft were porous and the tensile properties were in the range of the native ACL. When these novel grafts were used to reconstruct the ACL of rabbits, all animals after 6 weeks were weight-bearing and showed good functionality. Histological assessment confirmed tissue infiltration throughout the entire scaffold and tissue ingrowth and interlocking within the bone tunnels, which is favourable for graft fixation. In conclusion, this pilot study suggests that a tri-component, biodegradable graft is a promising strategy to regenerate tissue types necessary for ACL tissue engineering, and provides a basis for developing an off-the-shelf graft for ACL repair.
