Total Hip Replacement or Resistance Training for Severe Hip Osteoarthritis.

Background: Total hip replacement is routinely recommended for severe hip osteoarthritis, but data from randomized trials are lacking regarding comparison of the effectiveness of this procedure with that of nonsurgical treatment such as resistance training.

Methods: We conducted a multicenter, randomized, controlled trial to compare total hip replacement with resistance training in patients 50 years of age or older who had severe hip osteoarthritis and an indication for surgery. The primary outcome was the change in patient-reported hip pain and function from baseline to 6 months after the initiation of treatment, assessed with the use of the Oxford Hip Score (range, 0 to 48, with higher scores indicating less pain and better function).

Clinical investigations to evaluate high-risk orthopaedic devices: a systematic review of the peer-reviewed medical literature.

Purpose: The objective of this systematic review was to give an overview of clinical investigations regarding hip and knee arthroplasty implants published in peer-reviewed scientific medical journals before entry into force of the EU Medical Device Regulation in May 2021.

Methods: We systematically reviewed the medical literature for a random selection of hip and knee implants to identify all peer-reviewed clinical investigations published within 10 years before and up to 20 years after regulatory approval. We report study characteristics, methodologies, outcomes, measures to prevent bias, and timing of clinical investigations of 30 current implants.

Ceramic-on-Ceramic Total Hip Arthroplasty and Noises: A Prospective Blinded Randomized Controlled Trial of Influence of Component Design.

Background: Noises have been associated with ceramic-on-ceramic bearings in total hip arthroplasties. The etiology is multifactorial, but a high prevalence of noises was reported in studies using a specific acetabular component system. We examined if specific ceramic component designs are associated with the prevalence of noises in 2 commonly used component systems.

High dose dexamethasone in high pain responders undergoing total hip arthroplasty: A randomized controlled trial.

Background: Postoperative pain after total hip arthroplasty (THA) may delay postoperative mobilization and discharge. Postoperative pain has been shown to be higher in pain catastrophisers and patients receiving opioids. A single dose of glucocorticoid reduces pain after THA, and an increased dose of glucocorticoids has been found to be effective in patients at high risk of postoperative pain after total knee arthroplasty (TKA), however, the ideal dose in THA remains unknown.

Repeat dose steroid in high pain responders after total knee arthroplasty: A study protocol.

Pain after total knee arthroplasty (TKA) is a well-known clinical problem potentially delaying ambulation and recovery. Perioperative glucocorticoids reduce pain and facilitate early recovery, but the optimal timing and dose are still unknown. High pain catastrophizers have an increased risk of poorly controlled postoperative pain, and moderate to severe pain at 24 h is associated with a risk of pain relapse at 48 h.
