Plain English summary of protocol

Background and study aims
Anterior cruciate ligament (ACL) injury is a very common sports injury. It is reported that there are about 2 million cases of ACL injuries worldwide each year. ACL reconstruction (ACLR) is the main and standard surgery for ACL injury. Despite the development of techniques, grafts, and rehabilitation, 10-30% of patients still have rotational instability after isolated ACLR, increasing the risk of graft rupture, affecting patient movement and delaying patient recovery. The aim of this study is to explore the clinical outcomes of combining ACL reconstruction and anterolateral structure (ALS) reconstruction through a modified single femoral tunnel in patients with a high risk of clinical failure.

Who can participate?
Patients aged under 50 years undergoing ACLR combined with ALS reconstruction from December 2018 to August 2022

What does the study involve?
All procedures were performed by the same experienced surgeon. All patients received similar perioperative management programs. Measurements included function, stability and safety evaluations at different time points (preoperative, postoperative, 3 months, 6 months, 1 year, 2 years, 3 years and more).

What are the possible benefits and risks of participating?
Possible risks of the surgery include deep venous thrombosis, knee joint stiffness, and acute knee infection.

Where is the study run from?
Luoyang Orthopedic Hospital of Henan Province, Orthopedic Hospital of Henan Province (China)

When is the study starting and how long is it expected to run for?
June 2017 to December 2022

Who is funding the study?
1. National Natural Science Foundation of China
2. Project of Science and Technology of Henan Province (China)

Scientific titleMeniscus surgical treatment demonstrated inferior clinical outcomes as no meniscus injury with simultaneous combined anterior cruciate ligament and anterolateral structure reconstruction: a case-controlled study
Study objectivesPatients without meniscus injury have superior clinical outcomes. Meniscus repair and partial meniscectomy with simultaneous anterior cruciate ligament (ACL) and anterolateral structure (ALS) reconstruction could result in equivalent clinical outcomes.

Health condition(s) or problem(s) studiedCombined anterior cruciate ligament and anterolateral structure reconstruction
InterventionFrom December 2018 to August 2022, a total of 62 patients with ACL injury were enrolled in this study. All patients were associated with a high risk of clinical failure, meeting the indications of ALS augmentation, including 47 males and 15 females, aged 16-52 years with an average age of 29.3 ± 9.2 years. All patients accepted arthroscopic single-bundle ACL reconstruction and ALS reconstruction using hamstring autograft through a modified single femoral tunnel. Perioperative clinical outcome measurements comprised function, stability and safety evaluations at different time points (preoperative, postoperative 3 months, 6 months, 1 year, 2 years, 3 years and more). The functional evaluation included the Lysholm score, Tegner activity scale, and subjective and objective International Knee Documentation Committee (IKDC) score.
Intervention typeProcedure/Surgery
Primary outcome measure(s)

Knee-specific symptoms measured using the Lysholm score at preoperative, postoperative 3 months, 6 months, 1 year, 2 years, 3 years and more

Key secondary outcome measure(s)

1. Sports activity measured using the Tegner activity scale at preoperative, postoperative 3 months, 6 months, 1 year, 2 years, 3 years and more
2. Knee function measured using the subjective and objective International Knee Documentation Committee (IKDC) score at preoperative, postoperative 3 months, 6 months, 1 year, 2 years, 3 years and more
