Nele Sabbe, Does this look like a locked patella in this rhino? What can be done about it? Henry Labuschagne, [21 Dec 2023 at 15:47:06]: My 1st DD would be upward patella fixation. I have have seen cases where they were fed only lucerne. Some resolve spontaneously. If not resolving, do desmotomy same as in horses. Pierre Nel, Could be hip🤷? Henry Labuschagne, [22 Dec 2023 at 16:07:55]: That lump looks like tissue reaction / abscess / retained needle from previous darting or injection. It is unlikely to cause issues with hip joint or nerve. Ulf Tubessing, [23 Dec 2023 at 12:44:42]: I agree with Henry Nele Sabbe, [23 Dec 2023 at 13:43:45]: Seems that indeed it was a locked patella
