Full Vs Partial Weightbearing During the First Six Weeks of Rehab. After Fibular Collateral Ligament Reconstruction

November 20, 2024 updated by: Twin Cities Orthopedics

Full Weightbearing Versus Partial Controlled Weightbearing During the First Six Weeks of Rehabilitation After Reconstruction of the Fibular Collateral Ligament: a Randomized Controlled Trial

This is a prospective randomized controlled trial with the purpose to determine if patients undergoing fibular collateral ligament (FCL) reconstruction alone or combined FCL and anterior cruciate ligament (ACL) reconstructions can safely begin full controlled weightbearing for the first six weeks after surgery.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients will be randomly assigned to one of two rehabilitation protocols for the first six weeks post-surgery:

  1. partial weightbearing
  2. full controlled weightbearing

An immobilizer brace in extension will be used from post-operative day 0 through 13 and a CTi ligament knee brace (Össur Americas, Foothill Ranch, California) will be used from 14 to 42 days post-surgery to protect against side-to-side motion while weight bearing.

Specific Aims

  1. Primary Aim: To determine if there is a difference in millimeters of varus gapping on anteroposterior (AP) stress radiographs at six months post-surgery between patients who are partial weight bearing versus full controlled weight bearing during the first six weeks of post-surgical rehabilitation. This distance will be compared to varus gapping measured on the contralateral uninjured control knee.
  2. Secondary Aim: To determine if there is a difference in pain, edema, and range of motion, gait, quadriceps strength, and patient reported outcomes between groups.

The Investigators hypothesize that there will be no clinically significant difference (< 2 mm change) in varus gapping between the control and treatment groups. Results of this study will help to expedite return to pre-injury levels of activity and decrease adverse sequelae associated with non-weight bearing such as osteopenia, muscle atrophy, loss of ankle range of motion, and increased risk of deep vein thrombosis.

The current standard of care for FCL reconstruction is early controlled partial weight -bearing for the first six weeks after surgery.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

14 years to 59 years (Child, Adult)

Accepts Healthy Volunteers

Yes

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Partial weight -bearing for the first six weeks after surgery
Partial weightbearing will be defined as 40% of the patient's body weight.
Other: Physical Therapy
Patient is randomized to the weightbearing group the day after surgery.
Experimental: Full weight -bearing for the first six weeks after surgery
If the patient is randomized to the full weightbearing group, the patient will be instructed about acceptable exercises and activities.
Other: Physical Therapy
Patient is randomized to the weightbearing group the day after surgery.

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.
