Motor Imagery and Action Observation Training in Total Knee Arthroplasty: A Randomized Controlled Trial

This single-center randomized controlled trial aims to evaluate the effects of motor imagery and action observation training on pain, functionality, balance, and fear of movement in patients after total knee arthroplasty (TKA). The study will be conducted at Simav Doç. Dr. İsmail Karakuyu State Hospital Orthopedics Department with a minimum of 40 participants meeting the inclusion criteria. Participants will be randomly assigned to one of three groups: (1) standard physiotherapy, (2) standard physiotherapy plus motor imagery training, or (3) standard physiotherapy plus action observation training. All interventions will last six weeks. Standard physiotherapy will include ankle pumping, active-assisted hip and knee flexion, isometric and stretching exercises, cryotherapy, gait, and stair training. The motor imagery group will perform guided imagery sessions using audio recordings describing the physiotherapy exercises and daily activities. The action observation group will observe exercise videos corresponding to the physiotherapy program. The primary outcomes will include pain, functional level, balance, and kinesiophobia. The study aims to determine whether the addition of mental simulation techniques to standard physiotherapy can enhance postoperative recovery and improve functional outcomes in patients undergoing total knee arthroplasty.

Persona Revision Knee System Outcomes

The study will evaluate the performance, clinical benefits and safety of the Persona Revision Knee System in patients who have received primary or revision total knee arthroplasty (TKA) treatment. This will be done using a multicenter, single-arm, consecutive series, retrospective cohort study with prospective follow-up.

F18-MHF: Orthopedic Implants-Associated Infection Detection

Following intravenous injection of \[F-18\]MHF as a bolus, dynamic PET imaging of the lower limbs will be acquired for approximately 90 minutes. The acquired images will be processed and viewed on a MIMVista or similar workstation. The uptake pattern of \[F-18\]MHF around infected orthopedic knee implant will be determined and compared with its uptake pattern around non-infected knee implants. This study will look at how \[18F\]MHF goes into normal knee replacements and those with suspected infection.

Prospective Functional, Gait, and Outcome Comparison Study of Medial Pivot Versus Single Radius Design for Total Knee Arthroplasty

Patients with degenerative joint disease can effectively be treated with a primary total knee replacement to reduce pain and improve function in their daily lives. Theoretically, achievement of normal knee motion using a medial pivot design in total knee replacements can be recreated in comparison to single radius designs, which could lead to an improvement in post-surgical outcomes and satisfaction with the procedure. The aim of this study is to compare two types of implant designs (medial pivot and single radius) in a total knee replacement using clinical outcomes, patient reported outcomes, and overall function assessed by a specialized gait laboratory.

Comparison of Two Robotic-Assisted Total Knee Arthroplasty Systems

The goal of this prospective study is to compare two different knee replacement robots. This study will look at patient reported outcome measures and data collected during the operation. The main questions this study aims to answer include: * Will the patient reported outcomes differ between the two groups? * Will the intraoperative data differ between the two groups? Participants will undergo total knee replacement with one of the two robots, complete standardized surveys, and have x-rays taken.

Study Conducted on Patients Operated With a FHK ASYMETRIQUE to Confirm Security and Performance of the Device

This study is a post-market clinical follow-up conducted in order to collect long-term data on security and performance of the FHK asymetrique prosthesis, which is intended to be implanted in case of total knee replacement, when used in real life conditions according to the instructions for use.
