Outcome and Tunnel Widening After ACL Reconstruction: Comparison of Aperture and Cortical Fixation
ACL Anterior Cruciate Ligament Injury, Outcome
About this trial
This is an interventional treatment trial for ACL Anterior Cruciate Ligament Injury
Eligibility Criteria
Inclusion Criteria:
The ACL injury can be either "isolated" or combined with one or several of the following injuries visualized on MRI and/or arthroscopy:
- A meniscus tear that is either left untreated or treated with a partial resection
- A small, stable meniscus tear treated with fixation, but fixation not interfering with the rehabilitation protocol
- Cartilage changes verified on MRI with arthroscopically determine intact surface
A radiographic examination with normal joint status or combined with either one of the following finding:
- A small avulsed fragment located laterally, usually described as a Second fracture
- JSN grade 1 or osteophytes grade 1 as determined by the OARSI atlas (Altman et al. 1995)
- Agreement to participate in the study and signed informed consent prior to inclusion.
Exclusion Criteria:
1.Presence of one of the following associated injuries to the index knee as visualized on MRI and/or arthroscopy:
- An unstable longitudinal meniscus tear that requires repair and where the following postoperative treatment (i.e. bracing and limited ROM) interferes with the rehabilitation protocol
- Bi-compartmental extensive meniscus resection
- A cartilage injury representing a full thickness loss down to bone
- A total rupture of MCL/LCL as visualized on MRI
