The goal of this prospective, cross-sectional study is to test the strength of the soleus muscle in participants who have a ACL tear confirmed by MRI. Previous studies have shown that the soleus muscle, which one of the muscles situated in the calf, decreases mechanical loading on the ACL. Therefore, we aim to test soleus muscle strength using a seated plantar flexor test. The main questions we aim to answer are: - Do patients with ACL tears demonstrate inter-limb soleus strength asymmetry (>10%) - Do patients with ACL tears have soleus muscle weakness compared with uninjured (normative) participants? - Do changes in soleus strength values correlate with patient reported outcomes and stability, as measured by the IKDC questionnaire? To achieve this the VALD force frame will be used as the testing device for plantar flexor strength testing. This device records the force generated by the movement. This will be repeated three times on each leg as part of the testing procedure. Furthermore, as part of the testing procedure participants will be required to fill out an IKDC form to assess their knee stability. Interrater reliability of the force frame will be investigated. Further data from participants without ACL tears will be used to compare results. Thus allowing us to see if people with ACL tears have a weakness in the soleus muscle.
After anterior cruciate ligament reconstruction, altered muscle responses around the knee joint are seen, known as arthrogenic muscle responses (AMR). Despite their initially protective function, prolonged presence of these AMR may potentially lead to knee joint pathomechanics, which in turn could contribute to an increased risk of early knee osteoarthritis. In this trial, the treatment effect of standard physiotherapy on long-term AMR will be compared to the effects of physiotherapy incorporating cognitive dual-task training. Based on earlier strong indications of supraspinal physiopathological mechanisms for AMR, our hypothesis is that exercise therapy combined with cognitive dual-task training will lead to a more natural and less anxious muscle control, thereby reducing AMR. The presence of AMR will be evaluated 5 months post-operatively in ACL reconstructed patients. Patients who display AMR will be included in this randomized controlled trial. These individuals will be randomly assigned to one of the two treatment strategies and will undergo the respective therapy for six weeks (twice a week). Afterwards, the same test procedure conducted five months after the operation will be repeated two more times to assess the evolution of the AMR: at seven months post-operation to assess the training effect and at nine months post-operation to evaluate the retention of this effect.
This retrospective, prospective observational study aims to evaluate the epidemiology and rate of anterior cruciate ligament re- rupture after surgery in patients treated from January 2020 to December 2030 by recording both clinically and radiographically ligament reconstruction. The primary outcome is the rate of rupture of the anterior cruciate ligament as measured by the Lachmann test in which a positive value for re-rupture is an anterior translation of the tibia greater than 10mm relative to the femur Secondary Objectives: Verify predisposing factors to anterior cruciate ligament injuries (so anatomical factors such as tibial slope, trochlear groove), demographic factors (age, sex, weight, sports played), and the rate of return to sports, quality of life via questionnaires, and arthrosis at the operated knee
The Thermo-LCA study is a diagnostic interventional study for assessment of knee temperature of asymptomatic patients with ACL reconstruction compared with unoperated healthy contralateral knee. The aim of the study is to analyze thermographic images obtained from the knees of asymptomatic patients with ACL reconstruction that occurred between the previous 2 and 5 years, to assess the presence of inflammation in the knee with reconstructed ACL compared with the contralateral.
Knees injuries commonly affect the ACL. French current methodology is based on MRI focused on the knee with morphological sequences (T1, DP fat sat) allowing the study of ACL as follows: No lesion / Partial tear / Complete tear. The treatment (kinesitherapy, surgery, no intervention) is defined taking into account several factors such as age, knee laxity, physical activity and outcome of the radiology analysis (partial or complete tear). However, if the classification is straightforward in case of complete tear, it is not possible to establish a quantitative impact on the ACL in case of partial tear. As a consequence, the investigators will analyze the anisotropy coefficient with diffusion tractography. Any patient who undergo a posttraumatic knee MRI at the CHU Amiens Picardie will have an appointment at the 3T "Signa" MRI that has the knee-centric diffusion tractography sequence.
Anterior cruciate ligament (ACL) rupture is a serious trauma with long-term consequences to the athlete. Psychological and physiological factors may negatively affect patient recovery and increase reinjury rate after anterior cruciate ligament reconstruction (ACLR), and development of kinesiophobia is also possible.
Currently, most patients with an anterior cruciate ligament injury undergo surgery. There is a general belief that surgical reconstruction is necessary to safely return to sports and to prevent early knee osteoarthritis or additional meniscus injuries. But there is insufficient scientific evidence to support this belief. Moreover, several studies show that surgical reconstruction of the cruciate ligament does not guarantee successful return to sports or the prevention of osteoarthritis and secondary meniscus injuries. Therefore, immediate surgery after an anterior cruciate ligament injury is questioned. So far, only two RCTs (KANON study and COMPARE study) have assessed this, and they could not show that immediate reconstruction is an added value (in terms of symptoms, knee function, activity level, osteoarthritis or additional meniscal injuries) compared to a conservative approach consisting of rehabilitation and late surgery for persistent knee instability. Therefore, this additional multicenter RCT, aims to 1) verify these results and 2) to identify predictors that predict which patients in the conservative group will not require late surgery. This has not been investigated to date. It is suspected that factors such as symptoms, strength, findings on the MRI scan and psychological factors may play a role in whether or not a patient will be able to successfully rehabilitate without surgical repair. This information is invaluable to physicians because it allows them to decide which treatment is best for the patient.
This project will develop a data-driven decision making model to assess a competitive athlete's readiness to return to sport after ACL injury and surgery safely.
Anterior cruciate ligament (ACL) surgery patients experience physical trauma, both in the physical injury itself and following surgery, and face potential long-lasting adverse effects such as muscle weakness, diminished joint function, hip pain, and fear. Many of these patients report more significant anxiety and depression following surgery, which can further compound these patients' adverse outcomes. This study is a single-blind, randomized controlled trial design to evaluate the effects of a remotely-delivered 8-week mindfulness intervention on patient-reported outcomes (PROs) following ACL reconstruction surgery.
