Anyone had a Patellofemoral (Partial) Joint Replacement?
Joint Replacements | Last Active: May 30, 2021 | Replies (5)Comment receiving replies
I have not had a partial knee replacement yet and am scheduled for a TKA August 30. My surgeon does not think that partial knee replacements are as successful as a total knee and, therefore, is suggesting a TKA. I had an arthroscopy for a meniscus tear and scraping of arthritis from my knee cap. I am 7 weeks out from that surgery and not recovering well. My surgeon wants me to wait 3 months to improve the outcome of a TKA. Most of my knee is in good shape, it’s just the knee caps. I am going to get a 2nd opinion. Any feedback would be greatly appreciated!

@sloops here is some information that may be helpful for partial knee replacements.
Excerpt from article linked at the end:

"Results of Patellofemoral Replacement
It is difficult to know exactly how long a patellofemoral replacement will last. The implant designs have changed significantly in the last decade, in hopes that better implants will lead to better results.
Unfortunately, there is not much long-term data, and we are really left with shorter follow-up. In most of the studies have been done, 80% to 90% of patients will have good results in the first decade after patellofemoral replacement; whether or not they will hold up longer than that is not understood.2
We also know that the most common reason that a patellofemoral replacement will not work well is not because of a problem with the implant, but rather a problem in the rest of the knee joint—the part that was not replaced. About 25% of patients will eventually require conversion of their partial patellofemoral replacement to a total knee replacement as a result of worsening arthritis in the other compartments of the knee.2
This is why the patients who have the best results from patellofemoral knee replacement are those patients who have specific problems with their kneecap, such as a previous patella fracture or problems with patellar tracking. These conditions can lead to early wear of the cartilage under the kneecap.
