NCT ID: NCT05980442 Not yet recruiting - Clinical trials for Osteoarthritis, Knee

Comparative Study of Navigation-assisted OrthoPilot® Elite and Robotic-assisted MAKO® Total Knee Arthroplasty

ORMAK
Start date: June 2024
Phase:
Study type: Observational

Randomized, controlled, single center observational study to compare the safety and performance of navigation-assisted OrthoPilot Elite and robotic-assisted MAKO total knee arthroplasty (TKA). The aim of the study is the comparison of the clinical outcome between navigated and robotic-assisted TKA. The hypothesis of the study is that both treatments achieve similar results regarding functional and clinical aspects.

In-vivo Wear Behaviour of AS Coated Versus Uncoated Columbus® Total Knee Prosthesis

COLRAS
Start date: April 6, 2023
Phase:
Study type: Observational

This clinical study is a Post-Market Clinical Follow-Up (PMCF) measure and is aiming to compare the in-vivo wear behaviour of the Columbus® total knee prosthesis between the standard Cobalt Chromium (CoCr) and the multilayer coated so called "Advanced Surface" (AS) of the same implant. The clinical investigation is designed as a International, prospective, longterm non-interventional study in order to gain clinical data of many patients within the routine clinical application of the investigational device.

Exploratory Study on Safety of PEEK Knee Prosthesis

Start date: June 25, 2021
Phase: N/A
Study type: Interventional

In this study, 10 subjects will be underwent total knee arthroplasty with PEEK knee prosthesis and be followed up 3, 6, and 12 months after surgery. The safety of the knee prosthesis for total knee arthroplasty will be investigated based on X-ray, magnetic resonance imaging, thin-section CT, hematological indexes, knee function, complications and the occurrence of serious adverse events at the 12-month follow-up.

A Study on the Use of Tourniquet Use In Primary Total Knee Arthroplasty

Start date: May 5, 2015
Phase: N/A
Study type: Interventional

A tourniquet is often used in total knee arthroplasty (TKA) to achieve better visualization, reduce intra-operative bleeding and facilitate cement interdigitation. On the other hand, the associated risks include skin burns, soft tissue and muscle damage, injury of calcified vessels, increased swelling and stiffness of the joints, nerve injury, paralysis, and thromboembolic events. The automatic lower limb pneumatic tourniquet system (Zimmer) was applied to reduce blood loss during surgery. A prospective randomized controlled trial (RCT) was performed to investigate the best tourniquet strategy in TKA. The participants were randomly allocated to groups with different tourniquet strategies: Group 1) tourniquet inflation from skin to cement hardening (skin to cement); Group 2) tourniquet inflation only from cementation (cement only) and Group 3) tourniquet inflation from skin incision to skin closure (skin to skin). In addition to the blood loss and early postoperative outcomes, pain, soft tissue injury, and rehabilitation were also strictly monitored with a longer follow-up duration up to 6 months.

Post Market Clinical Follow-Up Study for EVOLUTION® BIOFOAM® Tibia and EVOLUTION® CS/CR Porous Femur

Start date: February 3, 2020
Phase:
Study type: Observational

MicroPort (MPO) is conducting this PMCF study to evaluate the safety and effectiveness of its EVOLUTION® BIOFOAM® Tibia and EVOLUTION® Cruciate Sacrificing/Cruciate Retaining (CS/CR) Porous Femur components, including EVOLUTION® CS tibial inserts. This type of study is required by regulatory authorities for all devices that have been approved in Europe to evaluate the medium and long-term clinical evidence.

Evaluation of The Safety And Performance of The Freedom Total Knee® System With The PEEK-OPTIMA Femoral Component

Start date: January 1, 2021
Phase: N/A
Study type: Interventional

Prospective, multi-centre, non-comparative, post-market surveillance clinical study

NCT ID: NCT03215407 Not yet recruiting - Clinical trials for Rheumatoid Arthritis of Knee

The Comparative Study of Intra-articular Injection of Tocilizumab and Compound Betamethasone

Start date: August 1, 2017
Phase: Phase 4
Study type: Interventional

Aim: Comparing the efficacy and safety of intra-articular injection of tocilizumab and compound betamethasone. Study design: A randomized, single-blind, parallel controlled and one center trial design. Sample size: 60 cases. Study content: Patients who meet inclusive criteria will be randomly divided into tocilizumab group and compound betamethasone group. In the baseline period, the investigators will collect patients' general information, disease information, disease activity score, laboratory results and images of articular ultrasound. After 4 weeks of injection, patients will be asked to come back, and their disease information, disease activity score, laboratory results as well as images of articular ultrasound will be collected. Finally, these data will be sorted and analyzed. Hypothesis: The efficacy and safety of intra-articular injection of tocilizumab is better than that of compound betamethasone.

NCT ID: NCT02362867 Completed - Clinical trials for Osteoarthritis, Knee

Balanced Knee System Clinical Protocol for IRB Approval

Start date: January 2003
Phase: N/A
Study type: Interventional

The protocol will define the clinical study for Ortho Development's Balanced Knee® System (BKS) for subsequent review and approval by an Institutional Review Board (IRB).This clinical study will compare the clinical outcomes of BKS to currently marketed devices.
