Handrails for staircase

We need handrails to be installed for a staircase in my parent's house. both my parents are well into their 80's and it is not safe for them to go up and down the stairs without the support of a handrail. It is a tricky staircase (see photos) and we will need advice on what type of handrail will be best. My dad will be going in for a hip replacement soon, so it is urgent to have the job completed before then.
