Joint Replacement

an orthopedic operative procedure in which the dysfunctional joint surface is replaced with an orthopedic prosthesis; or by remodeling or realigning the joint surfaces

joint replacement or arthroplasty

previous surgical procedures included __________ _________ where the joint surfaces were removed and scar tissue was allowed to fill the gap between the ends of the bones

excisional arthroplasty

what are some indications for arthroplasty?

osteoarthritis - cartilage damage

rheumatoid arthritis

avascular necrosis or osteonecrosis

congenital hip dysplasia

acetabular dysplasia

Arthroplasty has become very common, with what being the most likely to be replaced?

hips and knees

is a condition where the bones of the hip are abnormally shaped; results in damage to the joint

Femoroacetabular Impingement [FAI]

FAI can cause early _______ in athlets

Osteoarthritis

what are the types of treatment for femoroacetabular impingement

non-surgical or surgical

non-surgical treatment for femoroacetabular impingement

NSAIDS, activity modification, therapy

surgical treatment for femoroacetabular impingement

arthroscopic surgery

what are the three types of Femoroacetabular Impingement

Pincer, Cam, and combined

this is the FAI with extra bone extends out over the normal rim of the acetabulum

Pincer

this is the type of FAI with the femoral head that is not round (can have an abnormally large radius) and cannot rotate smoothly inside the acetabulum

cam

this is the type of FAI where both pincer and cam types are present

Combined

this is a surgical procedure in which the hip joint is replaced by a prosthetic implant

hip Replacement or arthroplasty

both the femoral head and acetabulum are replaced; highly successful

total hip arthroplasty

generally replace just the femoral head with a cap; is alternative to total hip replacement

hemiarthroplasty

what are the goals of a total hip arthroplasty

to relieve pain

restore functional motion

restore alignment

restore stability

results of THA are dependent on

patient factors

surgical technique

implant design

pre-op and post-op therapy

what is the average length of stay in hospital is

2-3 days if going to rehab

different techniques or approaches are defined by

the relationship to gluteus medius

approaches to the hip include

posterior, lateral, anterolateral, anterior, and greater trochanter osteotomy

most THA are done using the

posterior approach

what is the advantage of posterior approach?

allow access to the acetabulum and femoral head

preserves the abductors

components of the implants (THA)

acetabular cup (maybe 1 piece, or 2 pieces- a shell and a liner)

femoral component
