Filter by:This prospective feasibility study is designed to assess pre-operative BFR in patients awaiting ACL reconstruction. This study will serve the following: (1) to determine if BFR improves strength testing prior to surgery and (2) to determine if BFR reduces QF muscle group atrophy prior to surgery. Additionally, preliminary results on pre-operative clinical and quality of life scores will be collected. If this study shows encouraging results, it will serve as a template for a more comprehensive randomized control trial.
The aim of this study is to investigate muscular activations during various quadriceps exercises commonly used in clinical settings.
Anterior knee pain which might be due to patellofemoral malalignment is an inevitable post operative complication after an ACL reconstruction (ACLR). We combined the double bundle ACLR technique with lateral release technique to prevent patellofemoral malalignment post ACLR.
The goal of this [type of study: observational study] is to [detect concomitant KF and ALL injury in knees with ACL injury using MRI in both adult and pediatric patients and compare the effect of KF injury and multiple risk factors (concomitant injury to the ALL, medial collateral ligament [MCL], or anterior, central, or posterior part of the medial or lateral meniscus) on anterolateral rotatory laxity as measured by the pivot-shift test in a clinical setting.]. The main question [s] it aims to answer are: [Does the main risk factor for a high-grade pivot shift after acute ACL injury differ between pediatric patients and adults?] [Does Concomitant KF injury significantly affect the pivot-shift phenomenon in pediatric patients with acute ACL injury?] Researchers will compare [71 pediatric patients and 469 adults] to see if [main risk factor for a high-grade pivot shift after acute ACL injury differs between pediatric patients and adults?].
The purpose of this study is to compare double-bundle and single-bundle techniques for ACL reconstruction in a long-term 15-year follow-up. Our hypothesis is that the DB technique is better than the SB technique.
Anterior cruciate ligament (ACL) is a frequent and disabling injury in athletes. Most of the time, ACL reconstruction (ACLR) is consider for regaining function and returning to preinjury sports while reducing the risk of secondary injuries. However, the risk of secondary severe knee injury is increased after ACLR, especially in athletes returning to strenuous activities. If strength symmetry is considered as an important factor in the Return-to-sport (RTS) decision, there is conflicting data about the association between strength symmetry and the risk of second knee injury after ACLR. The main objective of this study was to test if knee muscles strength symmetry at 4 months was associated with the psychological readiness and incidence of subsequent severe injury of both knees at a minimum 2 years follow-up after ACL-R.
Background: Bone-patellar tendon-bone (BPTB) and a double-looped semitendinosus gracilis (hamstring group) graft are commonly used for ACL reconstruction. Short-term and mid-term studies show little to no significant difference between the two groups, and there are a few long term studies to compare results between the two grafts. Purpose: To compare the results after using either BPTB grafts or hamstring grafts 18 years after ACL reconstruction. Study design: Randomized controlled trial; Level of evidence II. Methods: 114 patients with ACL rupture between 2001 and 2004 were randomized to reconstruction with either BPTB graft or a hamstring graft. Patients were operated at four major hospitals. The 18-year follow-up evaluation included isokinetic testing of muscle strength, patient-reported outcome measures, clinical knee examination and an assessment of radiological osteoarthritis using the Kellgren-Lawrence classification. Hypothesis:Hypothesis is that there will be no difference in the long-term outcome between the two groups, as well hypothesis of no difference in patients with prosthesis after ACL reconstruction, arthrosis difference in operated knees and the rate of graft failure between the two groups. Previous follow-up studies showed a significant difference in total flexion work between the two groups, so detecting a persistent difference between the groups will be point of interest.
The purpose of this study is to compare the results of single-stage anterior cruciate ligament reconstruction combined with high tibial osteotomy and anterior cruciate ligament reconstruction alone in knees with varus malalignment and anterior cruciate ligament deficiency. Evaluation will be clinically, radiologically and time needed to return to pre injury activity level. Our Hypothesis: Simultaneous anterior cruciate ligament reconstruction and high tibial osteotomy provides good functional scores, low rate of graft failure and early return to pre injury activity level with minimal added morbidity.
Anterior cruciate ligament (ACL) injuries constitute a significant portion of major knee joint injuries sustained by young, active individuals, and significantly increase risk for long-term disability. Yet the recommended solution to restore joint stability following injury--ACL reconstruction (ACLR)--does not prevent post-traumatic knee osteoarthritis (PTOA). Post-traumatic quadriceps (dys)function is a hallmark characteristic following ACLR, reported to accelerate the onset of PTOA after ACL injury, making the recovery of muscle function a primary concern to clinicians. However, hamstrings muscle function is drastically underrepresented relative to the quadriceps in the context of recovery from ACLR, which impedes the ability to develop targeted treatment approaches. Persistent hamstrings weakness is widely reported in patients who undergo ACLR with a hamstring tendon (HT) autograft, which increases ACL strain, and may contribute to higher graft failure rates in this population. To effectively treat muscular impairments, underlying neuromuscular adaptations known to occur in response to ACLR must be targeted. Eccentric exercise is uniquely suited to enhance neuromuscular function. The Nordic hamstring exercise (NHE) is a specific form of eccentric exercise that is clinically relevant and easy to implement, but has not been explored as an intervention for hamstrings neuromuscular dysfunction in patients who undergo ACLR with HT. To establish an evidence-based treatment model, the investigators will use a single-blind, randomized controlled clinical trial to establish the feasibility and efficacy of a 4-week NHE protocol in patients who undergo ACLR with HT. Separate factorial ANOVAs will be used to assess the effects of group (NHE, control) and time (baseline, 4 weeks) on selected outcomes. Effect sizes will be calculated for within- and between-group comparisons. The investigators expect to observe improvements in hamstrings neuromuscular function following the NHE protocol, and that those improvements will be greater than the control group. Additionally, the investigators expect the protocol to be feasible in terms of intervention adherence and patient retention. This study will identify specific barriers to the implementation of NHE in patients who undergo ACLR with HT, and will provide support for the application of an easy to implement clinical intervention able to address a complex neurophysiological problem.
The main goal of a rehabilitation program after an ACL reconstruction is to regain mobility and muscle function and ultimately to return to sports participation. Purpose of the study: to investigate the effect of the accelerated rehabilitation program on knee pain, and function in patients post ACLR surgery. Fifty adult amateur males athletes who underwent ACLR surgery participated in this study, their age ranged from 18 to 35years.They were randomly assigned into two equal groups. Group (A) received accelerated rehabilitation protocol and group (B) received conventional physical therapy program. Treatment sessions were conducted 5 times per week for 22 weeks for both groups. All patients assessed pre and post treatment for pain intensity using visual analogue scale (VAS), and knee function using knee injury and osteoarthritis outcome score (KOOS), knee effusion, and LSI of Hop test.
