Design outcomes

Primary

Measure	Time frame	Description
rate of reoperations	one year follow-up period after Optimys femoral stem surgery	rate of reoperations after primary implantation of the Optimys short stem prosthesis

Secondary

Measure	Time frame	Description
rate of fractures	one year follow-up period after Optimys femoral stem surgery	rate of fractures after the implantation of short stem femoral implants
rate of infections	one year follow-up period after Optimys femoral stem surgery	rate of infections after the implantation of short stem femoral implants
anatomic alignment on anterior-posterior (ap) view in Degree°	at one year follow-up after Optimys femoral stem surgery	radiologic outcome defined by preciseness of the anatomic alignment compared to the contralateral side
subsidence	at one year follow-up after Optimys femoral stem surgery	radiologic outcome defined by rate of subsidence after the implantation of short stem femoral implants (mm)
rate of cortical hypertrophy	at one year follow-up after Optimys femoral stem surgery	rate of cortical hypertrophy
pain under stress (yes/no)	at one year follow-up after Optimys femoral stem surgery	clinical outcome defined by pain under stress (yes/no)
use of analgetics (yes/no)	at one year follow-up after Optimys femoral stem surgery	clinical outcome defined by use of analgetics (yes/no)
use of walking aids	at one year follow-up after Optimys femoral stem surgery	clinical outcome defined by use of walking aids
extent of periarticular ossification (PAO) according to Brooker classification system	at one year follow-up after Optimys femoral stem surgery	Brooker classification system divides severity of PAO into 4 types: A: islands of bone within the soft tissues about the hip B: bone spurs originating from the pelvis or proximal end of the femur, leaving at least 1 cm between opposing bone surfaces C: bone spurs originating from the pelvis or proximal end of the femur, reducing the space between opposing bone surfaces to less than 1 cm D: bone ankylosis of the hip
pain at rest (yes/no)	at one year follow-up after Optimys femoral stem surgery	clinical outcome defined by pain at rest (yes/no)
