Wojciech Satora, Aleksandra Królikowska, Andrzej Czamara, Paweł Reichert
The anterior cruciate ligament (ACL) is cited as the most frequently injured ligament in the knee. The standard treatment of ACL injury remains ligament reconstruction followed by a postoperative physiotherapeutic procedure. During the reconstruction, the torn ligament can be replaced with an autograft or an allograft. A synthetic ligament is also one of the available graft options. Synthetic grafts in ruptured ACL treatment have been used as scaffolds, stents, or prostheses. The story of using synthetic materials in ACL deficient knee treatment started in the beginning of the 20th century with the usage of silk and silver fibers...

PURPOSE: A comparison of clinical outcomes between double-bundle (DB) and single-bundle (SB) anterior cruciate ligament (ACL) reconstruction for patients with ACL injury. METHODS: Sixty patients were treated with either SB (n = 30) or DB (n = 30) ACL reconstruction between 2011 and 2012. The hamstring tendons were autografted with suspensory fixation on the femoral side, while a bio-absorbable interference screw was used for fixation on the tibial side. These patients were evaluated using Lysholm score, International Knee Documentation Committee (IKDC) forms (both objective and subjective), Lachman test, pivot shift test, and KT 1000 arthrometer...

Background: Pre-operative quadriceps strength may have a positive influence on post-operative function and outcomes at time of return to sport. Little consideration has been given to quadriceps strength during the early post-operative timeframes. Twelve-week post-operative anterior cruciate ligament reconstruction (ACL-R) is considered a critical time point for progression in the rehabilitation process. There is currently limited research looking at the relationship between clinical measurements pre-operatively and at 12-weeks following ACL-R...

Background: Recent evidence shows a delayed return to sport in children and delayed quadriceps recovery in both adults and children who have undergone anterior cruciate ligament (ACL) reconstruction with concomitant femoral nerve blockade (FNB) compared with those who had no blockade. We evaluated the use of adductor canal blockade (ACB), as an alternative to FNB, at the time of ACL reconstruction. Hypothesis: Patients who receive ACB will have greater isokinetic strength at 6 months postoperative compared with patients who receive FNB at the time of ACL reconstruction...

PURPOSE: To investigate whether an increased magnitude of quantitative rotatory knee laxity is associated with a greater level of generalized joint laxity in ACL-injured and contralateral knees. METHODS: A total of 103 patients were enrolled across four international centers to undergo anatomic ACL reconstruction. Rotatory knee laxity was evaluated preoperatively, both in the awake state and under anesthesia, using the standardized pivot shift test. Two devices were used to quantify rotatory knee laxity; an inertial sensor, measuring the joint acceleration, and an image analysis system, measuring the lateral compartment translation of the tibia...

BACKGROUND: The presence of a positive pivot shift after surgical repair of the ACL is considered an important indicator of a failed reconstruction. The ability to predict the result of a pivot shift test after an ACL reconstruction using variables that can be measured prior to surgery could provide an indication of which patients may be at-risk of a poor surgical outcome.The purpose of this study was to determine whether structural characteristics of the femur and tibia, measured using plain radiographs, were associated with the result of the pivot shift test in unilateral ACL reconstructed patients...

Background: Isokinetic strength testing is an important tool in the evaluation of the physical capacities of athletes as well as for decision making regarding return to sports after anterior cruciate ligament (ACL) reconstruction in both athletes and the lay population. However, isokinetic testing is time consuming and requires special testing equipment. Hypothesis: A single-jump test, regardless of leg dominance, may provide information regarding knee extension strength through the use of correlation analysis of jump height and peak torque of isokinetic muscle strength...

CLINICAL SCENARIO: A common injury among elite, recreational, and youth athletes is the anterior cruciate ligament (ACL) tear.(1) Approximately 200,000 ACL injuries occur every year.(2) The gold standard in ACL injury evaluation is diagnostic arthroscopy,(3,4) however the diagnostic accuracy of clinical diagnostic tests and magnetic resonance imaging (MRI) is debatable.(1,3-6) Due to the frequency of knee injury,(3) MRI is a common diagnostic tool used for imaging and diagnosis(5). ACL tears are also diagnosed using clinical diagnostic tests...

CONTEXT: Reductions in objectively measured moderate-to-vigorous physical activity (MVPA) have been reported among individuals with ACLR. Self-reported measures of physical activity are commonly utilized to assess participation in physical activity after ACLR despite the lack of evidence to support the validity of such measures within this population. OBJECTIVE: The objective of this research was to determine the relationships between objectively measured MVPA, self-reported physical activity, and knee function among individuals with ACLR...

PURPOSE: To compare the results of bone-patellar tendon-bone graft (BPTB), semitendinosus-gracilis graft with preserved insertions (STGPI) and semitendinosus-gracilis-free graft (STGF) in terms of graft failure, objective mechanical stability, functional outcome, and return to sports in elite and recreational sports persons. It was hypothesized that the STGPI graft provided superior outcome as compared to the other two grafts. METHODS: Two hundred and forty-nine elite and recreational players who underwent ACL reconstruction surgery, with BPTB graft (N = 80), STGPI graft (N = 85), and STGF graft (N = 84) with a minimum follow-up of 2 years, were assessed using clinical tests, knee arthrometer (KT 1000™), single-leg hop test, Lysholm knee score, Tegner's activity scale, and return to sports...

PURPOSE: To compare the different types of ACL reconstructions in terms of knee dynamic laxity evaluated by acceleration. METHODS: Sixteen fresh frozen cadaveric knees were used. Pivot shift test was manually performed while monitoring the tibial acceleration by use of a triaxial accelerometer. The test was repeated before and after the ACL resection and reconstruction. Three types of ACL reconstruction were tested: (1) Anatomic Single-Bundle reconstruction (n = 8), the graft was placed at the center of the ACL footprint for the both femoral and tibial sides (tunnel diameter: 8mm); (2) Conventional Single-Bundle reconstruction (n = 8), the graft was placed from the tibial PL footprint to femoral high AM position (tunnel diameter: 8mm) and (3) Anatomic Double-Bundle reconstruction (n = 8)...

The flexion angle of the knee and the position of the tibia need to be considered during tensioning of the anterior cruciate ligament (ACL) graft to avoid overconstraining the knee. The purpose of this report was to describe 2 cases of loss of tibial internal rotation after single-bundle anatomic ACL reconstruction with graft tensioning in flexion. Retrospective review of each patient's operative chart revealed that the graft was tensioned in flexion and placed in an anatomic position in the femoral tunnel at the time of the index operation...
