1. I've got a gammy knee.

2. Gammy: My great-grandfather gave it to my great-grandmother when they got married.

3. He ran the short distance down the side-street as fast as his gammy leg would let him.

4. The idea was to put him in it from time to time to give his gammy leg a rest.

5. He was in increasing pain from slipped discs, arthritic joints, a gammy foot and a growth on his chest.
