Corked thigh (corky): treatment and return to play
A corked thigh, or 'corky', is one of the most common injuries in footy, rugby, soccer and other contact sports: a direct blow, usually a knee, to the front or side of the thigh. Most are minor, but how you manage the first couple of days makes a real difference.
What is a corked thigh?
It's a contusion: the blow crushes the quadriceps muscle against the thigh bone, causing bleeding and swelling within the muscle. Contusions and strains make up the majority of quadriceps injuries in sport (Kary, Current Reviews in Musculoskeletal Medicine, 2010). You'll usually feel immediate pain, then increasing tightness and stiffness, with difficulty bending the knee and sometimes bruising over the following days.
What should I do straight after a corky?
Stop playing if you can't run and bend your knee normally. In the first 24 to 48 hours, apply ice and compression, and rest with the knee bent as far as is comfortable, which helps limit bleeding and stiffness. Elevate the leg when you can. Use crutches if walking is painful.
What should I avoid with a corked thigh?
For the first 48 to 72 hours, avoid heat, alcohol, vigorous massage of the injured area, and running or heavy exercise. All of these can increase bleeding in the muscle. Don't try to 'run it out'.
How bad is my corky?
How far you can bend your knee a day or two after the injury is a useful guide. If you can bend it well past 90 degrees, it's usually mild. Bending to between 45 and 90 degrees suggests a moderate injury. If you can't bend it to 45 degrees, and you're limping heavily, it's severe and should be assessed.
How long does a corked thigh take to heal?
Mild corkies often settle within a few days to a week. Moderate ones typically take two to three weeks, and severe contusions can take four to six weeks or more. Returning before you have full knee bend and strength risks re-injury.
When can I return to play after a corky?
You're ready when you have full, pain-free knee bending, quad strength close to the other side, and can sprint, jump, kick and change direction at training without pain. Protective padding over the area can help when you first return.
What exercises help a corked thigh recover?
After the first couple of days, start gentle pain-free knee bending and straightening, and static quad contractions. Then progress to stationary cycling, walking, and gradually loaded strengthening such as squats and lunges, followed by running, sprinting and sport-specific drills. Stretching should be gentle and pain-free.
What is myositis ossificans?
It's a complication where bone forms within the bruised muscle. It's more likely after severe contusions, or when the area is re-injured or treated too aggressively early on. Signs include a firm lump in the thigh, pain and stiffness that are getting worse rather than better after two to three weeks, and loss of knee bend. It needs medical assessment and imaging.
Can an osteopath help a corked thigh?
Yes. We assess the severity, check for other injuries, guide you through the early stages, and plan your return to training and games. Once the early bleeding phase has passed, hands-on treatment and graded exercise help restore knee movement and strength.
Should I massage a corky?
Not in the first few days. Vigorous massage of a fresh contusion can increase bleeding and is thought to raise the risk of complications. After the early phase, once swelling has settled and knee bend is returning, gentle soft tissue work around the area can help.
Can I play next week with a corky?
With a mild corky, often yes, provided you have full knee bend and can run, jump and kick without pain at training. With a moderate or severe corky, playing too soon risks a second knock to an already bleeding muscle, which usually means a much longer lay-off. If in doubt, get it assessed mid-week.
Does padding prevent corkies?
Thigh padding or protective shorts can reduce the force of a direct blow and are worth considering when returning from a corky, or for players who get them repeatedly.
When should a corky be checked urgently?
Go to an emergency department if the thigh becomes very tight, hard and swollen with severe, increasing pain, or you have numbness, tingling or coldness in the leg or foot. This can be compartment syndrome, which is a medical emergency. See a doctor for a corky that isn't improving after a week or two, or a hard lump in the muscle.
