Initial Graft Tension and ACL Surgery
Study Details
Study Description
Brief Summary
The anterior cruciate ligament (ACL) is one of four strong ligaments connecting the bones of the knee joint. If overstretched, the ACL can tear. Reconstruction of a torn ACL is now a common surgical procedure. The amount of tension applied to the ACL during reconstruction may indirectly affect the possible onset of arthritis over time. The purpose of this study is to determine the effect of initial graft tension set during ACL reconstruction surgery on the progression of knee arthritis over at least a 15-year period.

Detailed Description
Damage to the ACL is a common injury that usually requires surgical reconstruction to restore function and prevent progression of post-traumatic osteoarthritis. However, the reconstruction procedure frequently causes degenerative changes to the knee joint over time. The amount of tension applied to the ACL during reconstruction may indirectly affect the possible onset of arthritis over time. High tension would result in less joint motion during the initial healing stages, which may make the onset of arthritis less likely. On the other hand, high tension would result in increased compressive forces between the joint surfaces, which could lead to arthritis. The purpose of this study is to evaluate the effect of initial graft tension set during ACL reconstruction surgery on joint cartilage and the development of knee arthritis over at least a 15-year period.
Participants will include candidates for ACL reconstruction surgery using patellar tendon grafts. Participants will be randomly assigned to one of two treatment groups:
-
Low tension (Group 1) participants will receive low-tension treatment with initial graft tension set so that the anterior-posterior (A-P) displacement of the reconstructed knee is equal to that of the uninjured knee.
-
High-tension (Group 2) participants will receive high-tension treatment with initial graft tension set to reduce A-P displacement by 2 millimeters relative to that of the uninjured knee.
Participants will enroll in this 15-year study 1 to 6 weeks prior to ACL surgery. There will be two preoperative study visits: one will include magnetic resonance imaging (MRI) and the other will include a knee evaluation, dynamic function testing, and questionnaires. Postoperative visits occurred immediately following surgery and at 6, 12, 36, 60, 84, 120, 144 and 180 months following surgery. Strength testing, functional testing, x-rays, questionnaires, and a knee exam will occur at most postoperative visits. MRIs will occur at some postoperative visits. An additional group of participants with no evidence of knee injury will serve as a control. The control group will attend all study visits except for the 12-month visit. All participants may be followed for up to 15 years.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Low-tension Patients recruited to study the initial graft tension during ACL reconstruction surgery who were randomized to the Low-tension group will receive the low-tension treatment with initial graft tension set so that the anterior-posterior (A-P) displacement of the reconstructed knee is equal to that of the uninjured knee. |
Procedure: Initial graft tension during ACL reconstruction surgery
The amount of tension that is applied to the graft at the time of fixation is being performed with the knee in two different positions. When the knee is at 30 degrees of flexion, the resulting laxity is approximately 2 mm less than the contralateral leg (the "High Tension" treatment). When the tension is performed with the knee in extension (0 degrees of flexion), the the laxity is equal to that of the contralateral leg (the "Low Tension" treatment). Both methods are commonly used in clinical practice. The effect it may have on articular cartilage remains unknown.

Outcome Measures
Primary Outcome Measures
- Radiographic joint space narrowing [15 years]
Medial joint space width measurements were obtained from radiographs preoperatively and postoperatively using the semiflexed metatarsophalangeal view. Radiographs were taken of each knee, and the medial compartment joint space width was measured at the midline of the compartment in the coronal plane using a validated computer algorithm. (Duryea et al., Trainable rule-based algorithm for the measurement of joint space width in digital radiographic images of the knee, Medical Physics 27, 580 (2000); doi: 10.1118/1.598897). Subjects are identified as having radiographic signs of OA if they exhibit a change in the medial or lateral compartments greater that 0.30mm over the study period
Secondary Outcome Measures
- Knee injury and osteoarthritis outcome score (KOOS) [15 years]
The five dimensions of Knee Osteoarthritis Outcome Score were scored separately: pain , symptoms ,activities of daily life function, sport and recreation function, and knee-related quality of life . Each sub score has a 0-100 scale. 0- extreme knee problems and 100- no knee problems.
- Knee joint laxity [15 years]
Difference in Anterior-Posterior (A-P) knee laxity value; A-P laxity is defined as the amount of A-P directed translation of the tibia (relative to the femur) between the shear load limits of -90 N (posterior) and 133 N (anterior).
- Limb strength international knee documentation committee (IKDC) score [15 years]
Clinical outcome was assessed using the 2000 IKDC Knee Examination Score (http://www.sportsmed.org). The IKDC scores evaluate 4 categories: function, symptoms, range of knee motion, and clinical examination.The IKDC score rates knees as normal (A), nearly normal (B), abnormal (C), and severely abnormal (D), with the final IKDC rating based on the score of the worst category.
- Short Form-36 (SF-36) health survey [15 years]
The SF-36 evaluates general health related to physical function, role limitations, bodily pain, vitality, social functioning, mental health, and health transition. Each sub score is on a 0-100 scale. 100 indicates no problems and 0 indicates severe problems.
- Muscle atrophy [15 years]
Thigh circumference 6 cm above the joint line for injured and contralateral knees
- Whole Organ Magnetic Resonance Image Score (WORMS) [15 years]
The OA status of the knee was assessed using the semiquantitative Whole Organ Magnetic Resonance Imaging Score (WORMS).The score uses magnetic resonance imaging (MRI) sequences to grade 14 independent features: cartilage signal and morphological characteristics, subarticular bone marrow abnormality, subarticular cysts, subarticular bone attrition, and marginal osteophytes evaluated in 15 regions. The condition of the menisci, cruciate and collateral ligaments, synovitis, loose bodies, and periarticular cysts was also included for a total possible score of 332 points. 0-indicates no damage in anatomical landmarks assessed. 332-severe damage to the anatomical landmarks assessed.
- One-legged hop test [15 years]
Ratio of hop distance on the injured knee to the hop distance on the contralateral uninjured knee.
- Modified OsteoArthritis Research Society International (OARSI) score [15 years]
OARSI-The overall condition of the knee joints of both surgical and contralateral limbs were graded on radiographs by a radiologist. (0-83). 83-severe damage.0- no damage. The difference of the score between surgical and contralateral limbs is also presented.
- Isokinetic Strength [7 years]
Strength of quadriceps muscles was quantified by averaging the peak torques of 3 repetitions and normalizing these values with respect to body weight.Percent torque of surgical compared to contralateral is presented. If the quadriceps muscle of the surgical limb had the same peak torque as the contralateral, it would be 100%.
