Please can you decipher a medical term in a 1917 Admission and Discharge record?

[ARBELLA]

 I wonder, please, if anyone can kindly help me decipher a medical term on a publicly available Admission and Discharge Record from 1917 for a Lincolnshire soldier, Clifford Nicholson. (He is not a relative, but I am writing about him in a book, and wish to be accurate!) His record in blue from August 1917, is, I hope, attached. It comes from FindmyPast and is no clearer when originally viewed on my screen! Clifford’s entry has a medical term which appears to begin ‘B’ and end ‘iosis’. Can you read it, please? It may relate to a later record (in black) which I hope is attached. This November 1917 record refers to a knee injury. Clifford himself said in a newspaper interview in 1969 that, in 1917, he had been in England for machine gun training when he suffered a knee injury which lasted for months. Perhaps the illegible entry in blue is a medical term for the knee injury? Your expert help will be much appreciated!

I do hope it's permissible to add a note... I thought you might be interested, for various reasons, to see Clifford Nicholson's own remarks on the injury and the fighting in 1917. I am afraid that I do not have the previous page of his interview with The Lincolnshire Times, from 1969...Thanks for your time!

I think it says 'int derangement of knee joint'. Internal derangement of knee joint does appear in search results as a mechanical disorder of the knee.

The word giving trouble is Bilharziasis.

But the other details suggest this is not the same C. Nicholson as your man with the knee injury.

The soldier with bilharziasis was Gunner Charles E Nicholson 318292, Royal Garrison Artillery.

A detailed report of Lt Clifford Nicholson's wedding in June 1917 mentions that he had been out at the front for several months but for some time had been stationed at Windsor.

Thank you! That's most helpful

Thank you! That explains the lack of connection with the details of the knee injury! Much appreciated.

Thank you for deciphering this soldier's details for me! That explains the mystery.  Very grateful for your time.
