Replacement

This clinical study aims at evaluating clinical, radiographic and patient-reported outcomes after total anatomic or reverse shoulder replacement using PRIMA humeral stem up to 24 months after surgery, in order to assess the short-term performance of the implant. Furthermore, the objective is also to collect short-term data on the survivorship of the implant and the incidence of complications.

2:1 Randomized, Controlled, Multi-Center, Prospective, Pre-Market Study of the INHANCE Stemless Reverse Cementless Total Shoulder.

This study compares the analgesic efficacy of single-dose adductor canal block (sACB) versus continuous-dose adductor canal block (cACB) for postoperative pain management in total knee replacement patients. To ensure a high level of clinical accuracy, the investigation specifically focuses on a cACB cohort where ultrasound confirmation ensures the catheter remains correctly positioned for a full 48 hours. Participants are assigned to groups using a 1:1 randomization protocol via computer-generated tables to eliminate selection bias. Clinical consistency is maintained by using identical pharmacological agents across both groups: 0.5% Heavy Bupivacaine for spinal anesthesia and 0.5% ropivacaine with 1:200,000 epinephrine for the nerve block itself. Furthermore, both groups adhere to a standardized multimodal analgesic schedule to control for external variables. In the cACB group, intravenous patient-controlled analgesia (IV PCA) serves as a designated rescue therapy should the catheter fail. The primary technical evaluation occurs 48 hours post-surgery, utilizing ultrasound to verify catheter placement and quantify pain levels. Beyond immediate recovery, the study evaluates long-term success through Patient-Reported Outcome Measures (PROMs) at a 12-week follow-up, focusing on functional restoration and the patient's overall quality of life. By isolating the variable of catheter stability, the research aims to provide a definitive comparison of whether the continuous delivery of local anesthetic offers a statistically significant clinical advantage over a single-dose administration in the context of modern orthopedic recovery protocols.

Background: REAL INTELLIGENCE™ CORI™ (CORI Robotics) is a computer-assisted orthopaedic surgical navigation and burring system. CORI Robotics is designed to help surgeons in planning and executing certain types of knee surgery involving bone preparation. These types of surgery are called 'unicondylar knee arthroplasty' (UKA) and 'total knee arthroplasty' (TKA). Purpose: This study is being carried out to demonstrate the safety and effectiveness of the CORI Robotics in TKA procedure. The data collected will be used to demonstrate the safety and effectiveness of CORI and to register CORI in China mainland. The primary objective of this study is to evaluate the use of CORI in TKA procedure in achieving post-operative leg alignment as compared to procedures using conventional manual instruments. Research participants / locations: 140 research participants will be recruited from up to 8 sites in 3 countries globally (Australia, China Mainland, Hong Kong and New Zealand). There will be 70 patients having TKA using CORI and 70 patients having TKA using conventional procedure.

Direct Anterior Approach (DAA) is known to cause damage to the TFL during the surgical approach, the point of this study is to evaluate the impact between the severity of the per operative TFL damage and the functional short term results.

The study objective is to assess patient satisfaction after the surgery with a patient match CE marked implant (ORIGIN®) versus off-the-shelf (VANGUARD PS) device, and to document the clinical and device performance outcomes of the ORIGIN System used in routine hospital practice in a large patient cohort treatment of total knee arthroplasty.

The indicators of patient recovery in the postoperative period include sleep, physical functionality, mental health, cognitive functionality, pain, and psychosocial functionality. This thesis aims to investigate the effects of progressive relaxation exercises on postoperative pain intensity, sleep quality, and recovery in patients undergoing total knee arthroplasty.This study, designed as a randomized controlled experimental study, will be conducted between September 1, 2023, and August 1, 2024, at ÇAYCUMA State Hospital in ZONGULDAK province, Turkey, among patients undergoing total knee arthroplasty. A total of 96 patients will be recruited based on the sample size calculated using G-power analysis. Through block randomization, 48 patients will be assigned to the intervention group and 48 patients to the control group. Data will be collected using the Numeric Rating Scale for pain, the Richard-Campbell Sleep Scale, a sleep tracker smart wristband to measure sleep quality and duration, the Postoperative Recovery Index, and a Patient Information Form.

As China transitions into an aging society, the proportion of the elderly population is escalating, with a corresponding rise in the number of patients with knee joint diseases. Total knee arthroplasty stands as an effective treatment for joint disorders, effectively reducing knee pain, restoring functionality, and enhancing quality of life. The objectives of total knee arthroplasty are to relieve pain, restore function, and ensure a long-lasting implant. In recent years, technological advancements have integrated robotic assistance into total knee arthroplasty (TKA), aiding surgeons in planning and executing more accurate surgical plans, significantly enhancing precision and post-operative outcomes. However, the Mako mechanical axis alignment demonstrated during the Mako robot-assisted TKA procedure does not correspond to the actual straightening of the lower limb, and discrepancies may exist in sagittal alignment between Mako-assisted and manual TKA procedures, necessitating adjustments by surgeons based on their experience. Consequently, there is an urgent need to develop a mathematical formula that quantifies these differences to guide intraoperative alignment. Additionally, the Mako-assisted TKA femoral prosthesis exhibits a head-lowering issue, and differences exist in the posterior slope angle of the tibial plateau compared to manual TKA, necessitating further comparative analysis to draw definitive conclusions. This study will be carried out at the People's Liberation Army General Hospital, with an anticipated enrollment of approximately 100 participants.
