What are the chances of the surgery changing from a partial knee replacement to a full knee replacement?

Uncommon, age. If the partial knee replacement is performed correctly, one should expect it to last for many years. At the age of 38, you still need to avoid running for excercise, just as for a full knee replacement. If indicated, much better option for you at your very young age.
Nearly always. A partial knee will always need to be converted to full knee after a period of time depending on the state of and demands put on the implant.
Small chance . The key to partial knee replacement long term success is proper installation. When done correctly, 90% 20 year success rates are seen. Using robotics I have performed over 500 partial knee replacements and the installation accuracy is predictably within 1mm and 1 degree. This is the most consistently, reproducible way to install a partial knee replacement. Bearings can be changed in the future.

Immunosuppressed for 4 years, just contracted salmonella and have a partial knee replacement surgery in a month. Can I still have it with proper treatme?

Yes if properly. treated. The infection can be nasty in someone who has been immunosuppressed, though without clear idea of why you are suppressed. Usually you would need stronger and longer antibiotic treatment and close monitor of symptoms to ensure the infection has cleared completely prior to having surgery. Good luck and keep a strong relationship with your doctors. Read more...

What is the difference between an osteochondral surgery and partial knee replacement?

Preservation vs repl. Bone preservation vs bone replacement. Based on your age each has an advantage over the other. After 40 years of age replacement is a more predictable procedure. Read more...

Is a little pus on my partial knee replacement sight where the stitch is anything to be concerned about a month after surgery?

Yes,see your surgeon. "pus" at a surgery site always potentially concerning. It could be something relatively minor such as a buried absorbable stitch irritating the skin, or it could be a very serious problem of a deep infection in the joint. Only your surgeon should make that call and do it asap! Read more...
Yes. Yes it requires good local wound care. Clean it several times each day with hydrogen peroxide and cover and change bandaid regularly. This is usually a stitch that is working its way to the surface. Check with your doctor and you may need antibiotics to help clear the area up. Read more...

What are the chances of going from needing a partial knee replacement to a full knee replacement?

It depends. Typically, only approximately 10% of patients with knee arthritis will qualify for a partial knee replacement based on strict criteria. However, depending on what your symptoms are, expectations, and most importantly discussions with your surgeon, the threshold to going from a partial knee replacement and ending up with a full knee replacement may change.

High. Following strict criteria, only 5-10% of patients with knee arthritis are appropriate candidates for partial knee replacement. The goal of knee arthroplasty is to provide one successful surgery that lasts 20-25 yrs. Often, total knee replacement has a better chance of achieving this goal. Read more...
Not high. I agree that relatively few patients are good candidates for a partial knee replacement. But the chances of needing a conversion to a full are very low if the surgeon selects the right patient. Assuming that the author of the question has been advised by a surgeon skilled at selecting appropriate candidates for a partial, i would say that the risk is low. Read more...
High. Before i recommend partial knee replacement, xrays must demonstrate significant arthritic changes in only one of the three knee compartments, and the patient must convince me that their pain is emanating from that compartment. Despite fellowship training in knee arthroscopy, knee replacement, and revision knee replacement, i'd still rather provide one long-lasting surgery. Read more...
Small if done well. Success rates of well installed partial knee replacements is in the 90% at 20 years reported this year by dr. Scott at the knee society meeting. This is as good a total knee results but a good partial knee feels much more natural than a good total knee replacement. The difficult is getting a great installation every time. Using makopasty robotics consistently reproducible precision is expected. Read more...
