What are the benefits of physical activity after joint replacement?
- Maintain general health
- Enhance the quality of the interface between the bone and prosthesis (i.e. the healthier the bone - the better the fixation of the prosthesis)

Risk factors after joint replacement - most common reasons for revision surgery
- Periprosthetic osteolysis:
a. A biological response to particles released into the joint space from the prosthetic materials
b. Results in a loss of bone tissue. Has a direct relationship with joint-bearing surface wear (i.e. a combination of joint-load and frequency of joint use)
ex. Increased wear = increased osteolysis, Osteolysis can lead to implant loosening and the need for additional surgeries. - Traumatic injury
