ACL Tear Treatment in Seoul Back to stable knees
An ACL tear often happens in a split second: a pivot, a pop, then swelling. We help you decide between focused rehabilitation and arthroscopic reconstruction, based on your knee and your sport.
Gangnam Nanoori Hospital in Gangnam-gu, Seoul, near Hakdong Station (Line 7, Exit 10), treats ACL tears with help from English-speaking coordinators. Joint Center orthopedic surgeons confirm the tear with an examination and MRI, check for meniscus or cartilage injury, and recommend structured rehabilitation or arthroscopic ACL reconstruction depending on your stability and activity goals. To book, message WhatsApp +82-10-6290-9796.
What causes an ACL tear?
The anterior cruciate ligament (ACL) runs through the middle of the knee and stops the shinbone sliding forward and twisting. Most tears happen without contact, when the knee twists while the foot is planted. Tears often occur together with a meniscus tear.
Pivoting and cutting
Sudden changes of direction in soccer, basketball, badminton or tennis put high twisting load on the ACL.
Awkward landings
Landing from a jump with the knee straight or collapsing inward is a common cause of ACL injury.
Skiing and falls
Twisting falls on the slopes, or a direct blow to the knee in contact sports, can tear the ligament.
Signs of an ACL tear
Pain may settle within days, but the knee can stay unstable. Feeling better does not always mean the ligament has healed.
Common symptoms
- A pop felt or heard at the time of injury
- Rapid swelling within the first few hours
- Difficulty continuing to play or walk normally
- A feeling that the knee shifts or gives way
- Pain and loss of full bending or straightening
- Tenderness along the joint line if the meniscus is also hurt
Seek care urgently if you have
- An obvious deformity or inability to bear any weight
- Numbness, coldness or color change in the foot
- A knee locked so it will not straighten
- Severe, rapidly increasing swelling or calf pain
These may signal a fracture, dislocation, nerve or blood vessel injury, or a blood clot; if the situation is life-threatening, call 119.
If you are not sure whether your pain is a ligament injury, our knee pain guide explains other common causes.
How an ACL tear is diagnosed
An experienced examination is often enough to suspect an ACL tear. Imaging confirms it and shows any other damage inside the knee.
| Test | What it shows |
|---|---|
| Physical examination | Stability tests such as the Lachman test, swelling and range of motion |
| X-ray | Rules out fractures, including small avulsion fractures |
| MRI | Confirms the ACL tear and shows meniscus, cartilage and other ligament injuries |
Swelling can make the knee hard to examine in the first days. A repeat exam once it settles is often helpful.
Treatment for an ACL tear
The ACL usually does not heal back together on its own. Treatment aims to give you a stable knee for the life you want, whether that is daily walking or returning to pivoting sport.
Settle the knee
Ice, elevation, compression and crutches if needed. Early exercises restore full straightening and reduce swelling.
Structured rehabilitation
Physical therapy builds thigh, hip and balance strength. Some less active people regain a knee stable enough for daily life.
Decide on surgery
Reconstruction is often advised for pivoting athletes, recurring giving way, or when the meniscus also needs repair.
Arthroscopic reconstruction
A tendon graft replaces the torn ligament through small incisions, using knee arthroscopy.
Return to sport
A staged program over many months, with strength and movement testing before you return to cutting or jumping sports.
ACL reconstruction, before and after
Reconstruction does not stitch the old ligament together; it replaces it with a graft fixed into the bone on either side of the joint.

Common Questions
Can a torn ACL heal without surgery?
A fully torn ACL usually does not heal back together. However, some people, especially those who do not play pivoting sports, regain a knee stable enough for daily life with a good rehabilitation program.
I tore my ACL on a ski trip in Korea. What should I do?
Protect the knee with ice, elevation and crutches if walking is hard, and get it examined. Our coordinators can arrange an exam and MRI, and your surgeon can advise whether to start rehabilitation or plan surgery here or at home.
How soon should ACL surgery be done?
Surgery is often done once swelling has settled and you can fully straighten the knee, usually after some weeks of pre-surgery rehabilitation. Timing depends on other injuries, such as a meniscus tear that may need earlier repair.
How long until I can play sport again?
After ACL reconstruction, return to pivoting sport commonly takes around 9 months or more. Returning too early increases the risk of reinjury, so clearance is based on strength and functional tests, not time alone.
Does insurance cover ACL treatment?
We accept Korean National Health Insurance (NHIS) for enrolled foreign residents. For international or travel insurance, our coordinators explain the billing documents we provide so you can submit a claim; please confirm coverage with your insurer.
