Arthrocentesis vs Observation Study for Acute ACL Tears (ASPIRATE)
Arthrocentesis Study for Perioperative Intervention on Reducing Arthritis and Trauma-related Effects
The ASPIRATE trial is a randomized controlled trial evaluating the effects of pre- and post-operative knee joint aspiration in patients with an ACL injury. The study aims to determine if removing knee joint fluid can mitigate the increasing inflammation after surgery, reduce quadriceps atrophy, improve short-term pain, enhance functional recovery, and lower long-term rates of post-traumatic knee osteoarthritis.

Detaljerad beskrivning
While Anterior Cruciate Ligament Reconstruction (ACLR) successfully restores joint stability, patients still face challenges regarding long-term osteoarthritis and lower rates of returning to sports. Traumatic hemarthrosis-the buildup of blood in the joint following an injury and surgery-acts as a toxic agent that triggers cartilage degeneration. Furthermore, it causes arthrogenic muscle inhibition (AMI), which leads to quadriceps muscle shrinkage and abnormal walking patterns. This cycle is often referred to as the "second-hit phenomenon". While draining fluid from the knee (arthrocentesis) before surgery is common, performing repeat drainages after surgery to remove built-up blood is experimental. This study evaluates whether this low-cost, widely available procedure can safely interrupt that destructive cycle.
The main objective of this trial is to intervene in the hemarthrosis process to prevent or reduce the incidence of AMI and cartilage breakdown through pre- and post-operative joint drainage. Secondary objectives include assessing whether the procedure leads to less quadriceps muscle shrinkage, improves short-term pain, enhances leg strength at 3 and 6 months, accelerates return-to-sport rates, and reduces joint wear at a 1-year follow-up.
Eligible participants include individuals aged 15 to 40 years who experienced their injury 30 days or less prior, have a confirmed ACL tear, and have chosen to undergo ACLR using either a quadriceps tendon or bone-patellar tendon-bone autograft. Key exclusion criteria include previous knee or ACL surgery on the same leg, a cortisone injection within the previous 3 months, major multi-ligament repairs done at the same time (such as the MCL, PCL, or PLC), advanced osteoarthritis, pregnancy, or an inability to speak English fluently.
All participants will undergo standard ACLR surgery using their own tissue graft. Clinical assessments are conducted from baseline through 1 year, tracking patient surveys on knee pain, activity levels, and psychological readiness at baseline, 1 week, 2 weeks, 6 weeks, 3 months, 6 months, and 1 year. Physical and imaging steps include measuring thigh circumference with a tape measure at every visit, performing leg strength tests on a special machine at 3 and 6 months, and taking standing knee X-rays with a specialized framing device at the 1-year mark to evaluate joint health.

Experimentell: Aspiration
Each subject that is randomized to this arm will receive a knee aspiration both before and after ACL surgery. |
Aspiration is a minimally invasive medical procedure in which a sterile needle and syringe are inserted into the intra-articular space of the knee joint to extract excess synovial fluid that is built up around the knee space. |
|
Inget ingripande: No Aspiration
Each subject that is randomized to this arm will not receive an intervention and will only complete questionnaires. |

Quadriceps peak strength
Tidsram: 3 months and 6 months
|
The Biodex measurement physical device will be used to measure the isokinetic strength of the quadriceps muscle. The leg is brought from flexion to extension at 60 degrees per second and 300 degrees per second and the maximum force is measured for the quadriceps. This is compared to the contralateral side and expressed in the limb symmetry index (LSI) as the percentage of strength compared to the contralateral side. This is expressed N/m |
