Lateral Collateral Ligament (LCL) Injury
What Is the LCL?
The lateral collateral ligament (LCL) of the elbow — also called the radial collateral ligament — is a key stabilizing structure on the outer (lateral) side of the elbow joint. It connects the lateral humerus (upper arm bone) to the radius (forearm bone) and helps resist varus stress, which pushes the forearm toward the body. The LCL also works with surrounding structures to maintain elbow stability during motion and protect against dislocation.

What Is an LCL Injury?
An LCL injury occurs when the ligament is stretched, partially torn, or completely ruptured, often as a result of trauma, overuse, or repetitive strain. When the LCL becomes insufficient, it can lead to posterolateral rotatory instability (PLRI) — a condition where the elbow feels unstable or like it might “give out,” especially during pushing or weight-bearing activities.
Causes and Risk Factors
- Elbow dislocation (especially posterior)
- Falling on an outstretched hand
- Overuse from repetitive weight-bearing with an extended arm
- Prior elbow surgery (e.g., over-aggressive lateral approach)
- Chronic ligament laxity or instability
Symptoms of an LCL Injury
- Pain on the outside (lateral) of the elbow
- A clicking, catching, or popping sensation during movement
- Feeling of instability or “giving way,” especially when pushing up from a chair or doing a push-up
- Weakness with gripping or lifting
- Difficulty with daily tasks like pushing doors or stabilizing objects
Diagnosis
Diagnosis often includes:
- Physical exam including specialized tests like:
- Posterolateral rotatory drawer test
- Chair push-up test
- Imaging:
- MRI to confirm ligament damage
- X-rays to evaluate for bone or joint abnormalities
- CT scan if subtle instability or bony changes are suspected
Treatment Options
Non-Surgical Management
Effective in mild or partial tears:
- Rest and activity modification
- Elbow bracing or taping for stability
- Anti-inflammatory medication
- Physical therapy to strengthen surrounding muscles and improve dynamic stability
Surgical Treatment
Required for chronic instability or complete tears:
- LCL reconstruction or repair using a tendon graft or sutures
- Posterolateral corner stabilization if other supporting structures are involved
- Often performed arthroscopically or through a small lateral incision
Recovery Timeline
Non-surgical rehab:
6–12 weeks, with gradual return to activity
Post-surgical recovery:
Initial immobilization: 1–2 weeks
Progressive strengthening: 2–4 months
Return to sport/activity: 4–6 months, depending on stability and function

Patient Testimonials
highly skilled surgeon
“Dr. Kvitne operated on my shoulder 3 years ago and I had a perfect recovery and no problems since and I do not see a scar. He is kind with a great bedside manor and a highly skilled surgeon.”
Dr. Kharrazi truly got me back on my feet—literally.
One year ago, I tore several ligaments in my knee, and now I’m able to do the things I enjoy again.
His expertise, knowledge, and confidence are what made me choose him as my surgeon, and I will always be grateful to him and his entire team. Rudy, his assistant; Norma, who was always so prompt with all of my emails; and Blanca, who helped with forms—each of them made a difference. I can’t thank them enough for being there with me every step of the way.
