The OLT medical abbreviation most often stands for orthotopic liver transplant, an operation that removes a failing liver and puts a healthy donor liver in the same place. Orthotopic simply means in the normal position, which is how almost every liver transplant is done.
OLT shows up in transplant clinic notes, problem lists and hospital admissions for years after surgery, often written as s/p OLT. In foot and ankle care the same letters can name a cartilage injury in the ankle. This guide explains both, decodes typical chart lines and lists the terms that tend to travel with OLT.

What orthotopic liver transplant involves
In an orthotopic liver transplant the surgeon takes out the diseased liver and connects the new one to the same blood vessels and bile duct. The new liver may come from a deceased donor, or a portion may come from a living donor, since the liver can regrow to a working size.
Common reasons for transplant include cirrhosis from many causes, liver cancer such as HCC within set limits, sudden liver failure, and some inherited or bile duct diseases in children and adults. Fatty liver disease, now often written MASH, has become a frequent cause as well. Transplant centers decide who is listed using exams, lab results and scoring systems.
How OLT reads in real notes
Once someone has had a transplant, OLT tends to appear near the top of every chart. This sample line is typical.
| Chart text | Meaning |
|---|---|
| 58 yo M | A 58 year old man |
| s/p OLT | Status post, meaning he has had an orthotopic liver transplant |
| for alcohol related cirrhosis | The reason the original liver failed |
| on tacrolimus | Takes an anti rejection medicine |
Life after the transplant, as charts describe it
People who have had an OLT take medicines to keep the immune system from rejecting the new liver, usually for life. Notes may list generic names such as tacrolimus, cyclosporine or mycophenolate (MMF), plus regular blood level checks of these drugs.
Follow up visits watch liver tests, kidney function, blood pressure, infection signs and the drug levels. Words like acute cellular rejection, biliary stricture and hepatic artery thrombosis are complications that transplant teams look for. Their presence in a note means the team is checking or treating that issue, not that it is expected for everyone.
Medical abbreviation OLT in orthopedics
In foot and ankle surgery, OLT means osteochondral lesion of the talus. The talus is the bone at the top of the foot that forms the lower part of the ankle joint. An osteochondral lesion is damage to the cartilage on its surface and the bone just under it, often after an ankle sprain or injury.
These notes look very different from transplant notes: they mention ankle pain, MRI findings, arthroscopy and cartilage repair. A liver clinic letter and a sports medicine report will rarely be confused once you see the surrounding words.

Questions families often bring to the transplant team
- Which anti rejection medicines are needed, and how are their blood levels checked?
- What signs of rejection or infection should prompt a call?
- How often are clinic visits and lab draws in the first months?
- Which other medicines or supplements should be checked with the transplant pharmacist first?

Frequently asked questions
What does OLT stand for in medical terms?
It most often stands for orthotopic liver transplant, where a donor liver replaces the diseased liver in its normal position. In orthopedics, it can also mean osteochondral lesion of the talus.
What does orthotopic mean?
Orthotopic means in the usual anatomical place. A transplanted liver is placed where the old one was, which is why liver transplants are described this way.
What does s/p OLT mean?
It means status post orthotopic liver transplant, so the person has already had the operation. It usually stays on the problem list for life.
Is OLT the same as a living donor transplant?
Not exactly. OLT describes where the liver is placed, while living donor or deceased donor describes where it came from. A living donor transplant is still usually orthotopic.
