Letter to the editor: I have found the jewel in the crown of the NHS – the orthopaedic unit at Orpington Hospital.

I have just had a successful knee replacement there. The nursing staff were efficient and highly professional in carrying out their duties and always did them with big smiles on their faces, which I am sure assisted me in my healing.

All the staff at the unit, be it nursing, catering, cleaning, were all of various ethnic origins, but all worked harmoniously together. It gives one hope when there is so much despair in the world.
