Anterior cruciate ligament (ACL) tears are usually managed by reconstruction with autograft or allograft, but primary repair in carefully selected patients is a reasonable option. Proximal avulsions presenting early with excellent tissue quality are amenable to repair and healing. Restoration of native ACL preserves its proprioceptive and kinematic functions. A repair is less invasive and avoids graft-related problems, and faster rehabilitation is possible. Protection for the repair in the early stages will allow better healing...

Corneal opacities are a leading cause of global blindness. They are conventionally treated by the transplantation of donor corneal tissue, which is, restricted by a worldwide donor material shortage and allograft rejection. Autologous adult stem cells with a potential to differentiate into corneal stromal keratocytes (CSKs) could offer a suitable choice of cells for regenerative cell therapy. Postnatal periodontal ligament (PDL) contains a population of adult stem cells, which has a similar embryological origin as CSK, that is cranial neural crest...

The all-inside technique (AIT) for anterior cruciate ligament reconstruction (ACLR) is gaining popularity as a more anatomic, less invasive, technique with the potential for more rapid recovery. This systematic review aims to critically assess components of the technique, its safety profile, outcomes, and complications. PUBMED, EMBASE, and MEDLINE were searched for studies discussing primary ACLR using the AIT. Article screening, quality assessment, and data abstraction were completed in duplicate, and a minimal clinically important difference (MCID) was used to frame the descriptive results in a clinically significant context...

Surgical procedures for managing chronic lateral ankle instability include anatomic direct repair, anatomic reconstruction with an autograft or allograft, and arthroscopic repair. Open direct repair is commonly used for patients with sufficient ligament quality. Reconstruction incorporating either an autograft or an allograft is another promising option in the short term, although the longevity of this procedure remains unclear. Use of an allograft avoids donor site morbidity, but it comes with inherent risks...

The anterior cruciate ligament (ACL) rupture is a common disease that accounts for 250,000 cases/year in the United States. The anterolateral ligament (ALL) has been suggested to be an important restraint for rotational instability, and its reconstruction provides a reinforcement to the ACL reconstruction in this aspect, especially in high-demand athletes and in knees with high-grade pivot shift. Different techniques for associated ACL and ALL reconstruction have been described, but the ideal technique remains unclear...

Although surgical treatment is the gold standard for chronic patellar tendon rupture, the technique of patellar tendon reconstruction is still difficult. Basically, good clinical results of surgical repair for acute patellar tendon rupture have been reported. However, the results of reconstructive surgery for chronic patellar tendon rupture are still inconsistent. Some surgical options have been previously reported. For example, surgeons need to choose between 1- and 2-stage reconstruction. Furthermore, contralateral bone-tendon-bone graft, ipsilateral semitendinosus tendon graft, Achilles tendon allograft, and an artificial ligament have been used to reconstruct the patellar tendon...

BACKGROUND: Quadriceps tendon-patellar bone (QTPB) autograft is an excellent graft option with good clinical outcome. Use of QTPB autografts have increased because they minimize donor-site morbidity including anterior knee pain, while providing adequate mechanical strength. Although, there were many clinical results about allografts that used in anterior cruciate ligament (ACL) reconstruction, it have never been reported about the clinical outcome of ACL reconstruction with QTPB allograft...

Posterior cruciate ligament (PCL) injuries usually constitute part of a multiligament injury. Isolated PCL injuries account for only approximately 3% of all ligament injuries. No consensus on optimal surgical reconstruction exists. The PCL is a double-bundle structure that functions in an anisometric manner. Biomechanical studies have shown that re-creating the PCL femoral double-bundle configuration provides greater stability. We present a 3-socket approach for an anatomic "all-inside" double-bundle PCL reconstruction using our preferred option of a FiberTape (Arthrex, Naples, FL)-reinforced peroneus longus allograft fashioned to create a trifurcate graft: the TriLink technique...

Hamstring autografts in anterior cruciate ligament reconstruction have an excellent clinical track record, but some patients have hamstring tendons that yield grafts of smaller diameter, which has been shown to be a significant risk factor for worse outcomes and graft failure. Some authors have advocated augmentation with allograft in these patients. Tripling the semitendinosus yields a completely autogenous 5-strand graft with a larger diameter but still of sufficient length. In addition, imaging studies still show signal heterogeneity within grafts, even autografts, after the healing process, which correlates with worse biomechanical properties...

Approaches to management of combined anterior cruciate ligament (ACL) and high-grade medial collateral ligament (MCL) injuries remain controversial. Some studies suggest that with grade III MCL injuries, patients may benefit from concurrent MCL reconstruction to restore stability and prevent increased stress on the ACL graft. We present a technique for simultaneous ACL/MCL reconstructions using a single Achilles tendon allograft.

BACKGROUND: Anatomic graft reconstruction of the anterior talo-fibular ligament is an alternative for patients who are bad candidates for standard procedures such as a Broström-Gould reconstruction (high-demand athletes, obesity, hyperlaxity or collagen disorders, capsular insufficiency or talar avulsions). The purpose of this study is to describe an all-inside arthroscopic technique for ATFL reconstruction, and the results in a series of patients with chronic ankle instability. METHODS: We reviewed patients with chronic ATFL ruptures treated with an all-inside arthroscopic allograft reconstruction of the ATFL, with a minimum 2-year follow-up...
