The HAPI 'Hip Arthroscopy Pre-habilitation Intervention' study

INTERVENTION: Intervention group: exercises will be taught to you eight weeks prior to surgery, that will be done at home. You will be individually taught the specific techniques of the exercises, given an accompanying colour guide and a diary.
