Project description:The anterior cruciate ligament (ACL) is the most commonly injured ligament in the knee, with injury usually occurring as a result of multidirectional sports. The incidence of ACL injury has continued to increase, with most patients opting for surgery to improve stability as well as permit a return to sport. Traditional methods of ACL reconstruction can achieve this but are not without their problems, including graft rupture, residual laxity, and donor-site morbidity. There is therefore a requirement for further research into newer, innovative surgical techniques to help improve complication rates. This article describes, with video illustration, ACL reconstruction using a reduced-size bone-patellar tendon-bone autograft with suture tape augmentation. The augmentation acts as a stabilizer during the early stages of graft incorporation while resisting against reinjury during an accelerated recovery. The ability to use a reduced-size graft decreases the donor-site burden, and retention of residual native ACL tissue, when possible, may help with proprioception.

Project description:Anterior cruciate ligament (ACL) injuries and subsequent surgical reconstruction are exceedingly common orthopaedic procedures. Surgical technique and graft preparation techniques continue to evolve as surgeons seek to increase surgical outcomes and decrease recovery time. As such, there is significant interest in identifying tools and techniques that may enhance the surgical process for patients undergoing an ACL reconstruction. Recently, there has been significant interest in evaluating biologic scaffolds that may augment graft healing. This Technical Note describes our technique for the preparation of a bone-patellar tendon-bone ACL graft with a BioBrace biocomposite scaffold augmentation.

Project description:Anterior cruciate ligament (ACL) reconstruction augmentation continues to be widely studied. Both biologic and synthetic augments have been employed to enhance ACL healing and provide early protection. The BioBrace is a biocomposite scaffold that both mechanically reinforces the graft while biologically enhancing graft healing. The purpose of this article is to describe augmentation of an ACL reconstruction with BioBrace.

Project description:Anterior cruciate ligament (ACL) tears are among the most common sports-related injuries. Although studies have reported reliable outcomes with allograft tissue, several studies have shown a higher failure rate in younger patients. Although ACL graft augmentation has been met with varying levels of success, internal bracing of an allograft represents a promising area in ACL reconstruction. The purpose of this article is to detail allograft preparation involving a collagen-coated, ultrahigh-molecular-weight polyethylene/polyester suture tape as an internal brace augmentation for ACL reconstruction using the all-inside ACL GraftLink Technique (Arthrex, Naples, FL).

Project description: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.

Project description:Revision anterior cruciate ligament (ACL) reconstruction is substantially more challenging than primary reconstruction. Management of previously malpositioned or widened tunnels often requires innovative approaches for managing bony defects. Massive osteolysis with poor bone stock and convergence or overlapping of revision tunnels into the previously placed tunnels may necessitate a staged revision procedure. In this surgical technique description, we describe a method for the management of bony deficiencies using allograft bone dowels in staged revision ACL reconstruction.

Project description:After anterior cruciate ligament (ACL) reconstruction, the tibial tunnel becomes widened over time. A revision surgery of the ACL reconstruction is required to fill the widened tunnels. Bone-patellar tendon-bone grafts often are used to fill enlarged bone tunnels. However, due to the variation in tendon length, it is often difficult to adjust the position of the bone fragment to the enlarged part of the bone tunnel. This study describes an arthroscopic ACL reconstruction technique using the semitendinosus tendon as well as a bone fragment which is placed in the enlarged tibial tunnel. The tendon and cortical bone were collected together at the tendon attachment using a flat chisel. The bone fragment was inserted through the tendon in a controlled manner and ultimately placed at the posterior wall of the tibial foramen. This technique was determined to be less invasive than using bone-patellar tendon-bone in a 2-stage revision ACL reconstruction. In addition, this technique can be easily performed by any surgeon who is accustomed to conventional ACL reconstruction using the semitendinosus tendon and does not require any special equipment. Our findings suggest that this technique may be useful for revision ACL reconstruction.

Project description:Recurrent patellar instability is a common problem and often leads to a tear of the medial patellofemoral ligament. Multiple reconstruction techniques for the medial patellofemoral ligament (MPFL) exist. This Technical Note presents a technique for performing MPFL reconstruction using Achilles tendon allograft with a bone block. The advantages of this technique include (1) bone-to-bone healing in femoral tunnel; (2) docking the bone block in the femoral tunnel obviates the knee for calculating graft and tunnel length; (3) fixing the femoral side before the patellar side allows graft tensioning under direct visualization and avoids over-constraint; (4) the fanned portion of the Achilles tendon allows broad-based MPFL footprint coverage on the medial patellar ridge; and (5) it avoids the need for bone tunnel drilling in the patella, reducing the risk to penetration of the drill holes into the articular cartilage surface as well as the risk for patellar fracture.

Project description:The exclusive autograft choice for medial collateral ligament (MCL) reconstruction that has been described until today is the semitendinosus tendon. However, this has some potential disadvantages in a knee with combined MCL-anterior cruciate ligament (ACL) injury, including weakening of the hamstring's anterior restraining action in an already ACL-injured knee and nonanatomic distal MCL graft insertion when leaving the semitendinosus insertion intact at the pes anserinus during reconstruction. Moreover, because some surgeons prefer to use the hamstring for autologous ACL reconstruction, the contralateral uninjured knee hamstring needs to be harvested as a graft source for the MCL reconstruction if autografts and not allografts are the surgeons' preference. We describe a technique for performing combined reconstruction of the MCL and ACL using ipsilateral quadriceps tendon-bone and bone-patellar tendon-bone autografts. This technique of MCL reconstruction spares the hamstring tendons and benefits from the advantage provided by bone-to-bone healing on the femur with distal and proximal MCL tibial fixation that closely reproduces the native MCL tibia insertion.

Project description:The bone-tendon-bone (BTB) autograft is widely used for anterior cruciate ligament (ACL) reconstruction. However, the primary disadvantages of this technique include postoperative kneeling pain, the risk of perioperative patellar fracture, and graft-tunnel mismatch. Therefore, a single bone plug technique for ACL reconstructions was developed to mitigate the disadvantages of the BTB technique. To differentiate this graft, we have coined the term BTA, for bone-tendon-autograft. The middle third of the patellar tendon is used with a typical width of 10 to 11 mm. A standard tibial tubercle bone plug is harvested. The length of the patellar tendon and graft construct is then measured. If the tendon is >45 mm and the construct at least 70 mm, then we proceed with the BTA technique. At the inferior pole of the patella, electrocautery is used to harvest the tendon from the patella. The advantages of this technique include faster graft harvest and preparation. Obviating the patellar bone plug harvest should eliminate the risk of perioperative patellar fracture and theoretically will mitigate donor site morbidity and kneeling pain, 2 of the most commonly cited complications of the use of BTB autografts for ACL reconstruction. In conclusion, the BTA technique is a reliable technique for ACL reconstruction.
