Total hip arthroplasty (THA) is one of the most cost-effective and consistently successful surgeries performed in orthopedics .  THA provides reliable outcomes for patients suffering from end-stage degenerative hip osteoarthritis (OA), specifically pain relief, functional restoration, and overall improved quality of life. OA affects millions of Americans, and with an incidence of 88 symptomatic cases per 100,000 patients per year, translating to hip OA claiming the top underlying diagnosis leading to THA. Other underlying diagnoses include hip osteonecrosis (ON), congenital hip disorders, and inflammatory arthritis. The underlying diagnosis that leads to a degenerative hip is an important consideration as this has been shown to impact overall outcome. Overall, THA provides consistent short-term and long-term pain relief and positive patient-reported clinical and functional outcomes. In general, THA provides even more reliable and consistent positive results compared to its counterpart procedure, the total knee arthroplasty (TKA)., (Copyright © 2022, StatPearls Publishing LLC.)

Total knee arthroplasty (TKA) is one of the most cost-effective and consistently successful surgeries performed in orthopedics. Patient-reported outcomes are shown to improve dramatically with respect to pain relief, functional restoration, and improved quality of life. TKA provides reliable outcomes for patients suffering from end-stage, tri-compartmental, degenerative osteoarthritis (OA). While OA affects millions of Americans, the knee is the most commonly affected joint plagued by this progressive condition which is hallmarked by a gradual degeneration and loss of articular cartilage. Estimates project the annual incidence of symptomatic knee OA at 240 per 100,000 patients per year, and about 400,000 primary TKA surgeries are performed annually in the United States. The most common clinical diagnosis associated with TKA is primary OA, but other potential underlying diagnoses include inflammatory arthritis, fracture (post-traumatic OA and/or deformity), dysplasia, and malignancy., (Copyright © 2022, StatPearls Publishing LLC.)
