As people get older, many biological changes take place in the structure of their bones and joints. One change that can cause significant pain and loss of functional ability is degenerative joint disease, also known as osteoarthritis. Osteoarthritis (OA) is defined as the degenerative changes of the hyaline articular cartilage on the ends of bones that make up a joint.
OA can cause the formation of divots and/or osteophytes (bone spurs) on the end of the bone within the knee joint (i.e., distal end of the femur and tibial plateau). Walking and standing can cause compression of the joint and can put pressure on the osteophytes formation. As a result, the individual may experience pain and may potentially decrease his or her mobility in an effort to avoid the pain from the hyaline articular cartilage breakdown.
Many older adults who experience this pain during standing and walking will elect to undergo a total knee replacement surgical intervention known as total knee arthroplasty (TKA). Personal trainers should be aware of the effects that are commonly experienced by people who have undergone this surgery as well as the interventions and exercises that can help these clients regain functionality.
