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

- Registration Number
- NCT05073263
- Lead Sponsor
- Twin Cities Orthopedics
- Brief Summary
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.
- 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.

Group Intervention Description Partial weight -bearing for the first six weeks after surgery Physical Therapy Partial weightbearing will be defined as 40% of the patient's body weight. Full weight -bearing for the first six weeks after surgery Physical Therapy If the patient is randomized to the full weightbearing group, the patient will be instructed about acceptable exercises and activities.
