“…The younger THA cohort in our study included a large number of patients with osteonecrosis, similar to the proportion reported by Crowther and Lachiewicz [5]. The younger patients were also more often men, and higher activity levels were noted specifically among male patients with OA.…”

“…THA has demonstrated effectiveness for lessening pain and improving function for younger patients [3,5,10,16,17,20,22,28]. In our study, activity level and functional scores increased the most substantially for younger male and female patients with a diagnosis of OA.…”

“…Schmalzried et al [27] previously associated a higher incidence of polyethylene wear with male patients and increased activity levels among a small cohort of 24 patients. Crowther and Lachiewicz [5] associated increased conventional polyethylene wear rates and periprosthetic osteolysis with higher postoperative HHS in younger patients. Because average HHS was higher in older male and female patients than younger patients in our study-the opposite of other functional activity measures that were higher in younger patients-our results suggest that other measures of functional activity may be more appropriate to measure and report than the HHS when attempting to correlate bearing surface wear with patient activity.…”

“…More recently, Babovic and Trousdale [3] reported low wear rates of crosslinked polyethylene among patients aged 50 years or younger but longer followup is still needed to define longevity. Although a variety of diagnoses can result in an indication for THA, patients B 50 years old have generally been characterized as ''active'' [3,5,15,16,23,33].…”

Background Surgeons perform THA to address a variety of conditions in younger patients, including osteoarthritis (OA), osteonecrosis, inflammatory arthritis, and congenital deformities. Younger patients aged 50 years or younger have been characterized as active in the literature, but a direct relationship between age and activity level has not been well substantiated. Younger patients with OA may engage in higher activity levels; however, associated medical conditions in patients with other surgical indications may not support a generalization that age is a surrogate for activity level. We recently evaluated these issues in younger patients undergoing total knee arthroplasty (TKA) and noted that the majority would not be considered active. Given this observation, we considered whether younger patients undergoing THA are characterized by high activity levels, which is relevant to understanding the long-term risk of wear-related failures.Questions/purposes (1) Do demographic features of younger patients undergoing THA support high activity expectations? (2) Do preoperative or postoperative functional activity measures support projections that younger patients are active after THA? Methods We retrospectively compared demographic characteristics and functional activity profiles (as determined by preoperative and postoperative UCLA activity scores, Harris hip scores [HHS], and SF-12 and WOMAC physical function subscores) of 704 patients who had undergone THA and were aged younger than 50 years (822 hips) with those of 484 patients (516 hips) aged between 65 and 75 years, who had undergone THA, with a minimum followup at 1 year after surgery (range, 12-160 months). Results Compared with patients aged 65 to 75 years, younger patients undergoing THA were more often men (51%, 95% confidence interval [CI], 48.8%-53.2% versus 40%, 95% CI, 37.1%-42.9% women; p \ 0.01) or had undergone surgery for osteonecrosis (29% versus 4%; 95% CI, 2.8%-5.

“…THR can relieve pain and improve function, activity of daily life (ADL), and quality of life. Therefore, THR is used for treatment of femoral neck fracture across age groups from very young [21] to older patients [22]. However, inflammation due to infection in the artificial joints is a significant potential complication.…”

Contemporary alumina‐on‐alumina total hip arthroplasty performed in patients younger than forty years: A 5‐year minimum follow‐up study

et al. 2006

Ceramic-on-ceramic bearing surfaces in total hip arthroplasties (THAs) are an attractive alternative coupling and may offer a promising option for young active patients. We evaluated the clinical results of 72 contemporary primary cementless alumina-on-alumina THAs performed in 61 patients younger than 40 years (mean age, 30 years), after a 5-year minimum follow-up. Most patients (97%) were able to return to their prearthritic activity levels, and none changed occupation because of a postoperative hip joint problem. No implant loosened radiographically and no stem or cup was revised. Ceramic wear was undetectable in 24 hips, where differentiation of the femoral head from the cup was possible on radiographs and no osteolysis was observed. One ceramic fracture following a major motor vehicle accident and a recurrent subluxation-associated ceramic liner edge fracture attributed to inadequate hip muscle tone occurred. We believe that this alternative articulation offers a promising option for young active patients. However, our findings also suggest that contemporary ceramic implant fracture is not a potential, but a real danger. Careful preoperative patient evaluation, proper indications for ceramic bearings, and meticulous surgical techniques are recommended to minimize the possibility of modern ceramic failure.
