BACKGROUND: Almost 30% of young athletic patients sustain a second anterior cruciate ligament (ACL) injury within 24months of their ACL reconstruction and returning to pivoting sports. Most patients with high athletic demand and significant anteroposterior instability often require ACL revision surgery to restore their pre-injury activity levels. CASE REPORT: A 24-year old gentleman ruptured his hamstring tendon autograft during a twisting injury seven months after his ACL reconstruction...

BACKGROUND: Ulnar collateral ligament reconstruction (UCLR) has become a common procedure among baseball players of all levels. There are several graft choices in performing UCLR, one of which is a hamstring (gracilis or semitendinosus) autograft. It is unclear whether the hamstring muscle from a pitcher's drive leg (ipsilateral side of the UCLR) or landing leg (contralateral side of the UCLR) is more active during the pitching motion. We hypothesized that the landing leg semitendinosus will be more electromyographically active than the drive leg...

Anterior cruciate ligament (ACL) is the most commonly injured ligament occurs in young adult population, which markedly reduces activity level. Anterior cruciate ligament rupture is a threat to the homeostasis of the knee. So, reconstruction of the ACL is necessary to make them fit and return to their pre-injury activity level. The choice of graft for ACL reconstruction is a matter of debate, with the BPTB graft and quadruple graft of ST-G being the two most popular options. Use of triplet graft of semi-tendinosus tendon alone without sacrificing gracilis is another option...

How to enhance tendon graft incorporation into bone tunnels for achieving satisfactory healing outcomes in patients with anterior cruciate ligament reconstruction (ACLR) is one of the most challenging clinical problems in orthopaedic sports medicine. Several studies have recently reported the beneficial effects of Mg implants in bone fracture healing, indicating the use potential of Mg devices in promoting the tendon graft osteointegration. Here, we developed an innovative Mg-based interference screws for fixation of the tendon graft in rabbits underwent ACLR and investigated the biological role of Mg-based implants in the graft healing...

INTRODUCTION: Lateral tenodesis (LT) is performed to limit the risk of iterative tear following anterior cruciate ligament (ACL) reconstruction in at-risk patients. By adding an extra procedure to isolated ACL graft, LT reconstruction increases operating time and may complicate postoperative course. The objective of the present study was to evaluate the rate of early complications. The study hypothesis was that associating ALL reconstruction to ACL reconstruction does not increase the complications rate found with isolated ACL reconstruction...

Background The incidence of knee ligament injury is increasing and represents a significant cost to healthcare providers. Current interventions include tissue grafts, suture repair and non-surgical management. These techniques have demonstrated good patient outcomes but have been associated graft rejection, infection, long term immobilization and reduced joint function. The limitations of traditional management strategies have prompted research into tissue engineering of knee ligaments. Objective This paper aims to evaluate whether tissue engineering of knee ligaments offers a viable alternative in the clinical management of knee ligament injuries...

INTRODUCTION: After undergoing anterior cruciate ligament (ACL) reconstruction, patients must recover at least 80% of their hamstring and quadriceps strength to be able to return to sports without risk to the graft. Harvesting of the patellar tendon leads to large deficits in quadriceps strength, while harvesting the hamstring tendons leads to large deficits in hamstring strength. However, there are no published studies on the strength deficit after ACL reconstruction with the fascia lata...

INTRODUCTION: Anterior cruciate ligament (ACL) reconstruction can be performed with an autograft, which is most often harvested from the patient's hamstring tendon (HT) or patellar tendon (PT). However, autograft harvesting leads to morbidity that is by no means insignificant.A systematic review of literature was performed to define the incidence of complications related to graft harvesting and the methods to prevent these complications. MATERIALS AND METHODS: In March 2017, a systemic review of literature was performed using the keywords"harvesting", "harvest", "morbidity", "complication", "cruciate ligament"...

REVIEW
Jeremy M Burnham, Vonda Wright
As female athlete sports participation has continued to increase, the rate of anterior cruciate ligament (ACL) rupture in female athletes has also increased. Individualized, patient-specific treatment is crucial to achieving optimal outcomes; ACL reconstruction must accurately restore native ACL anatomy and address any concomitant injury to secondary stabilizers. Rehabilitation programs should target hip, core, and trunk neuromuscular control; allow adequate time for graft ligamentization; and address the psychosocial needs of the athlete...

BACKGROUND: Abnormal joint motion has been linked to joint arthrosis after anterior cruciate ligament (ACL) reconstruction. However, the relationships between the graft properties (ie, structural and anatomic) and extent of posttraumatic osteoarthritis are not well defined. HYPOTHESES: (1) The structural (tensile) and anatomic (area and alignment) properties of the reconstructed graft or repaired ACL correlate with the total cartilage lesion area 1 year after ACL surgery, and (2) side-to-side differences in anterior-posterior (AP) knee laxity correlate with the total cartilage lesion area 1 year postoperatively...
