Thirty patients (30 knees) who underwent total knee arthroplasty at age =50 were reviewed. These patients were operated on between July 1, 1991, and May 1, 1995, with final follow-up evaluation at a mean of 86 months (range, 60-107 months). At final evaluation, 18 knees (60%) had excellent Knee Society objective scores, 11 knees (37%) had good scores, and 1 knee (3%) had a poor score. There were no statistically significant differences in Knee Society objective scores among the cemented group (mean, 88 points), hybrid group (mean, 88 points), and noncemented group (mean, 90 points). One patient (3%) had a revision because of unexplained pain. In the other knees, there was no radiographic evidence of progressive loosening, lucencies, or change in position or alignment of the prosthesis. Total knee arthroplasty of this design, at least for the time period studied (7-year mean follow-up), has a high rate of success in patients who are =50 years old.

Distal femoral replacement (DFR) with megaprostheses is a salvage revision total knee arthroplasty (rTKA) procedure indicated in cases with massive bone defects in the distal femur. As long as these implants achieve fixation only in the diaphysis, the high aseptic loosening rate reported in some series is probably related to a lack of rotational stability. Two patients with extensive distal femoral bone defects with preservation of the metaphyseal-diaphyseal junction underwent rTKA.

Background: In the knee joints of patients with recurrent patellar dislocation (RPD), an increased relative tibial external rotation (rTER) is often observed. However, the changes in this parameter pre- and postoperatively remain unclear.
Purpose: The purpose of this study was to reveal preoperative and postoperative changes in rTER in patients with RPD.

Surgical thrombectomy has been established as an effective treatment for acute limb ischemia (ALI). Nevertheless, manipulation via the common femoral artery (CFA) to retrieve thrombus in the infra-popliteal artery sometimes proves less effective. We retrospectively reviewed patients undergoing surgical thrombectomy for infra-inguinal ALI from January 2010 to December 2022.

Aim: Fatigue is a common health problem in older adults. Chronic pain is associated with fatigue. However, the longitudinal association between chronic pain and the incidence of subjective fatigue among community-dwelling older adults remains unclear.
View Article and Find Full Text PDFBackground: Quadriceps dysfunction is ubiquitous after anterior cruciate ligament (ACL) reconstruction (ACLR). Addressing quadriceps dysfunction is crucial to improve function, reduce the reinjury risk, and maintain long-term knee health. While deficits specific to the quadriceps are well documented, less is known about the effect of an ACL injury on other lower extremity muscle groups.
