Knotless Suture in Revision Total Joint Arthroplasty

April 16, 2024 updated by: NYU Langone Health

Knotless Suture in Revision Total Joint Arthroplasty: A Prospective Randomized Controlled Trial

Barbed suture has been demonstrated to be safe in primary hip and knee surgery and retrospective data suggests barbed suture represents no increased complications in the revision setting. Barbed suture may represent a faster, more effective way to perform revision arthroplasty closures. There are no Level I studies comparing traditional and barbed suture closure. The purpose of this study is to assess the surgical complexities of closures using closure time without sacrificing cosmesis or wound complications between the traditional closure and barbed closure.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Device: Barbed suture closure: Knee
The barbed suture closure will consist of number 2 Stratafix symmetric PDS PLUS for the arthrotomy, intermediate layer will be performed at surgeon's discretion in thin patients, if performed will entail stratafix spiral, subdermal 2-0 stratafix spiral monocryl plus. Followed by subcuticular 3-0 stratafix spiral monocryl plus suture and Dermabond advance.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time of Closure in Minutes
Time Frame: Up to a maximum of 66 minutes (perioperative)
Measurement of the time needed to properly close the wound with each technique.
Up to a maximum of 66 minutes (perioperative)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Incidence of Complications Related to Wound Closure
Time Frame: Day 90
Number of all complications (including needle sticks and glove perforations) and infections related to the wound closure.
Day 90
Patient and Observer Scar Assessment Scale (POSAS) Score
Time Frame: Week 6 Post-Surgery
The POSAS consists of two parts: a Patient Scale and an Observer Scale. Both scales contain six items that are scored numerically on a ten-step scale, where 0 = normal skin and 10 = worst scar imaginable. Together they make up the 'Total Score' of the Patient and Observer Scale, which ranges from 0 to 120; higher scores indicate worse scars.
Week 6 Post-Surgery
Mean Number of Sutures Used
Time Frame: 45 minutes (perioperative)
45 minutes (perioperative)
Mean Length of Incision
Time Frame: 30 minutes (perioperative)
30 minutes (perioperative)
