Optimizing total hip arthroplasty: the gripper table mounted system for enhanced soft tissue preservation and postoperative outcomes.
In total hip arthroplasty (THA), soft tissue retraction is crucial, but traditional methods may cause damage. This study addresses the issue by introducing the Gripper Table Mounted System, a pulley-based retraction system. The research compares THA outcomes with and without the Gripper system, whether reducing soft tissue damage and postoperative pain. The Gripper, with its unique design, aims to minimize tissue damage during surgery. ⋯ Therapeutic Level III.

Frequent complications of deficient patellae after component removal in 1.5-stage exchange arthroplasty for periprosthetic joint infection.
To compare the complication rates between deficient patellae (remnant patellae after component removal) and non-resurfaced patellae after 1.5-stage exchange arthroplasty for periprosthetic joint infection and identify risk factors for complications of deficient patellae. ⋯ III.

The role of the medial head of the gastrocnemius myocutaneous flap transfer in the management of prosthesis exposure and deep joint infection following total knee arthroplasty.
There is a lack of effective and innovative treatment for patients with prosthesis exposure and deep joint infection following total knee arthroplasty. This study explores the application of the medial head of the gastrocnemius myocutaneous flap transfer in these conditions, offering new therapeutic strategies for clinical practice. ⋯ Medial head of the gastrocnemius myocutaneous flap transfer effectively improves knee joint function and activity, reduces pain, alleviates inflammatory reactions, and has fewer adverse reactions and a lower recurrence rate.

Anterior femoral offset is a flawed measurement of patellofemoral overstuffing.
Patellofemoral joint (PFJ) issues after total knee arthroplasty (TKA) are becoming a topic of interest once again. Due to the complex three-dimensional shape of the trochlea, various two-dimensional proxy measurements on plain X-rays have been described. One of these measurements is the anterior femoral offset (AFO). It is the distance between the anterior femoral cortex and the trochlea's most anterior point (MAP) on a true lateral X-ray after TKA. Because the relationship between the trochlea's MAP and its groove, which is the primary joint surface articulating with the patella, is unknown, the purpose of this study was to measure the distance between the MAP and the trochlear groove. ⋯ On a true lateral X-ray, the trochlea's MAP omits the trochlear groove. Because the patella primarily articulates with the trochlear groove and because the relationship between the MAP and the trochlear groove is variable depending on the knee flexion angle, any conclusions regarding overstuffing based on a postoperative lateral knee X-ray are flawed.
