This study is looking at how removing excess fluid from your knee or injecting Platelet-Rich Plasma (PRP) affects swelling after a sudden tear of your anterior cruciate ligament (ACL). Researchers want to see if these procedures change the healing factors in your knee joint fluid. You might be able to join if you are between 18 and 50 years old, speak English, have a recently torn ACL with swelling, and are scheduled for ACL reconstruction surgery. The main goal is to measure the concentration of a specific cytokine (a protein that affects cells) called Collagen Type II, from when you join until your surgery. The study is currently unclear on its status and plans to enroll 99 participants.

Study design

This is an interventional study planning to enroll 99 participants. It will involve either withdrawing synovial fluid or injecting Platelet-Rich Plasma (PRP).

What's involved

You would have synovial fluid withdrawn at a preoperative clinic visit and again during surgery. You might also receive a Platelet-Rich Plasma (PRP) injection.

Compensation

Not stated in the trial record.

Follow-up

The primary endpoint, Collagen Type II Cytokine concentration, will be measured from enrollment up to the time of surgery.
