Introduction. The degree of cartilage degeneration assessed intraoperatively may not be sufficient as a criterion for patellar resurfacing in total knee arthroplasty (TKA). However, single-photon emission tomography/computed tomography (SPECT/CT) is useful for detecting osteoarthritic involvement deeper in the subchondral bone. The purpose of the study was to determine whether SPECT/CT reflected the cartilage lesion underneath the patella in patients with

Spinopelvic mobility describes the change in lumbar lordosis and pelvic tilt from standing to sitting position. For 1° of posterior pelvic tilt, functional cup anteversion increases by 0.75° after total hip arthroplasty (THA). Thus, spinopelvic mobility is of high clinical relevance regarding the risk of implant impingement and dislocation. Our study aimed to 1) determine the proportion of OA-patients with stiff, normal or hypermobile spino-pelvic mobility and 2) to identify clinical or static standing radiographic parameters predicting spinopelvic mobility. This prospective diagnostic cohort study followed 122 consecutive patients with
While total joint replacement (TJR) is considered as an effective intervention to relieve pain and restore joint function for
The goals of a total knee arthroplasty include approximation of the function of a normal knee and achievement of balance post-surgery. Accurate bone preparation and the preservation of natural ligaments along with a functional knee design, holds the potential to provide a method of restoring close to normal function. Although conventional knee arthroplasty is considered a successful intervention for

Limited strong data exists in current literature comparing the 90-day morbidity and mortality following general or spinal anesthetic in patients who underwent total hip or knee arthroplasty, especially between matched cohorts. Because of this, there continues to be an ongoing debate regarding the risks and benefits of using general versus spinal anesthetic for patients undergoing elective total hip arthroplasty (THA) or total knee arthroplasty (TKA) for
Introduction. Total hip arthroplasty (THA) is a highly successful procedure achieving excellent clinical outcomes beyond 10 years post-surgery. With exception of periprosthetic infection, dislocation is the most common cause of failure in THA. A novel reverse total hip (RTH) replacement has been developed to address dislocation through reversal of the typical THA articulation in which a femoral cup and acetabular ball interlock at the extremes of motion to enhance mechanical stability in all planes. The purpose of this study was to assess the safety and efficacy of this novel RTH in a series of 22 patients and to monitor implant fixation using radiostereometric analysis (RSA). Methods. Twenty two patients with

Purpose. To update current surgical management of knee osteoarthritis. Methods. A literature review was done using standard keyword search. Articles were scrutinized by the investigators to ensure relevancy to the purpose of this review. Summary of the review. Arthroscopy, osteotomy and arthroplasty are three major techniques for knee osteoarthritis. Arthroscopy is more and more common as it is diagnostically and therapeutically useful, especially for patients with painful osteoarthritis with mechanical symptoms. Recently, arthroscopic techniques to treat subchondral bone marrow lesions associated with knee osteoarthritis have been developed. Osteotomy is a technique that preserves the natural biomechanics of the joint and reestablishes joint alignment. Its accuracy has been improved with the advancement of computer-assisted surgery. Arthroplasty includes Unicompartmental knee arthroplasty (UKA) and Total knee arthroplasty (TKA). In UKA, patient selection is a key factor for good outcomes, which can be enhanced with newer implant designs and robotic technology. TKA is the mainstay technique for
