What sets LAOSS apart
- Same- or next-day appointments at eight Los Angeles-area offices
- On-site imaging; PT coordinated with your in-network provider
- Conservative-first care, surgery only when needed
- Board-certified specialists, not generalists
Key takeaways
- An MCL, PCL, or LCL tear is one of many knee conditions our specialists evaluate every day.
- Most isolated MCL tears and many PCL tears heal with bracing and physical therapy. Complete LCL tears and injuries to more than one ligament are more likely to need surgery.
- When a procedure is the right call, we explain every option, recovery timeline, and return-to-activity milestone.
- On-site imaging at most offices and same-day appointments across eight Los Angeles-area locations.
What is an MCL, PCL, or LCL tear?
Tears of the MCL, PCL, or LCL (the collateral and posterior cruciate ligaments) typically follow a direct blow or twisting injury to the knee. Pain, swelling, or a loose feeling in the knee after an injury should be evaluated early.
Most isolated MCL tears, and many isolated PCL tears, heal with non-surgical care: a hinged brace, a short period of protected weight-bearing, and physical therapy. Complete LCL tears and injuries involving more than one ligament are less likely to heal on their own and more often need surgical repair or reconstruction. Our specialists match the plan to which ligament is torn and how unstable the knee is.
Below, we walk through the anatomy involved, the symptoms and causes we most often see, how we diagnose an MCL, PCL, or LCL tear, and the full range of treatment options, from the simplest to the most involved.
Watch: Medial Collateral Ligament (MCL) Injury
This is a stretching or tearing of a ligament on the inner side of your knee. The medial collateral ligament, commonly called the "MCL", is connected to the femur and to the tibia. The MCL helps stabilize your knee. This ligament, along with the lateral collateral ligament, helps prevent excessive side-to-side movement of your knee joint. It helps keep the upper and lower leg aligned properly.
Inside the knee.
The knee is the body's largest hinge joint: it bears your weight, absorbs impact, and lets you walk, run, and pivot. Cartilage and meniscus cushion the joint, while ligaments (ACL, PCL, MCL, LCL) keep it stable. Most knee problems come from wear of those cushioning surfaces or from twisting injuries that damage a ligament or meniscus.
Symptoms and causes of an MCL, PCL, or LCL tear
Common symptoms
- Pain on the inside, outside, or back of the knee
- Swelling within hours of injury
- A "loose" or unstable feeling, especially on uneven ground
- Difficulty bearing weight or fully straightening the knee
Common causes
- Direct blow to the side of the knee (contact sports)
- Twisting injury with foot planted
- Hyperextension of the knee
- Dashboard-style impact (PCL)
How we diagnose an MCL, PCL, or LCL tear
You want answers, fast, and we're built to give them. Most patients leave their first LAOSS visit with a clear diagnosis and a written plan, not another referral chain.
Here's what your initial visit for an MCL, PCL, or LCL tear typically looks like:
- Detailed history: when it started, what makes it better or worse, what you've already tried
- Focused exam of the knee: range of motion, stability, strength, specific provocation tests
- On-site imaging at most offices: X-ray for bone, ultrasound or MRI when soft-tissue detail is needed
- A written plan with options ranging from conservative care to surgical procedures, in plain English

How we treat an MCL, PCL, or LCL tear at LAOSS
Once we've confirmed the diagnosis, the next step is matching the right treatment to your situation. We start with the least-invasive option that fits, and escalate only when it doesn't.
Conservative care
Step 1Conservative care first
Non-surgical options designed to relieve pain, restore movement, and avoid the OR when possible.
- Rest, ice, and anti-inflammatory medication early on
- Hinged knee brace to protect the healing ligament
- Crutches for a short time if walking is painful
- Physical therapy to restore motion and rebuild strength, with a focus on the quadriceps
- Gradual, supervised return to sport
Surgical care
When neededSurgical options when needed
Minimally invasive and reconstructive procedures performed by board-certified orthopedic surgeons.
- MCL repair or reconstruction for tears that stay unstable
- LCL and posterolateral corner repair or reconstruction
- PCL reconstruction with a tendon graft for severe or combined injuries
- Multi-ligament reconstruction when more than one ligament is torn
- Staged physical therapy after surgery
Why experience matters.
Why experience matters
Knee care is highly technique-dependent. Volume, training, and judgment together determine the outcome you actually feel six months later.
- Precise diagnosis from imaging and exam
- Conservative-first care that avoids unnecessary surgery
- Surgical technique refined over thousands of cases
- On-site imaging + coordinated PT through your in-network provider
The LAOSS approach
Our knee specialists move stepwise: start with the least-invasive option that fits your situation, escalate only when it doesn't.
- Same-day imaging at most offices
- PT coordinated in your insurance network
- Board-certified surgeons performing the procedures themselves
- Direct access to your specialist between visits
Am I a candidate?
If most of these match your situation, an evaluation with a knee specialist is the next step.
You may be a candidate if
These signs typically point toward an in-person evaluation with a knee specialist.
- Pain or stiffness in the knee that lasts more than a few days
- Swelling, instability, or noticeable change in function
- Symptoms that limit walking, lifting, sleep, or work
- Previous treatment that didn't fully resolve the problem
- Imaging or exam findings that suggest an underlying issue
What evaluation includes
Your first visit is built to give you an answer the same day, not just another referral.
- Detailed history: onset, mechanism, what makes it better or worse
- Hands-on exam focused on the affected joint or region
- On-site imaging at most offices (X-ray, ultrasound)
- Clear plan with options ranging from conservative to surgical
- Same-day or next-day scheduling for any follow-up tests
ImportantSeek urgent evaluation for sudden severe pain, numbness, progressive weakness, or any sign of infection (fever, increasing redness or swelling).
Your knee recovery roadmap.
Recovery is rarely a straight line, but a clear plan with measurable milestones makes the path predictable.
- Days 0 to 14
Right after care
In the first two weeks we focus on protecting the knee, calming inflammation, and restoring basic motion.
- Activity modification with clear do/don't guidance
- Ice, elevation, and pain control as needed
- Gentle range-of-motion within safe limits
- Follow-up scheduled to track healing
- Weeks 2 to 8
Rehabilitation
Targeted physical therapy rebuilds strength, mobility, and confidence in the knee.
- Progressive strengthening and neuromuscular work
- Manual therapy and soft-tissue treatment
- Sport- or job-specific movement re-training
- Coordinated PT through your in-network provider
- Months 2+
Long-term care
Once function is restored, the focus shifts to keeping you there, and catching any recurrence early.
- Return-to-activity plan with measured benchmarks
- Home program tailored to your sport or job
- Maintenance visits or imaging if symptoms change
- Direct line back to your specialist if needed
Risks & considerations
What to weigh before you decide.
We talk through the risks and benefits with every patient. Informed consent is a conversation, not a form.
General considerations
Every orthopedic intervention carries a small set of standard risks. We screen, prepare, and monitor for these on every patient.
- Infection (rare with modern technique and prophylaxis)
- Bleeding or bruising at the treatment site
- Reaction to anesthesia or medications
- Need for additional procedures in some cases
Knee considerations
Some risks are tied to the structures we're treating in the knee. We discuss these in detail at your visit so you can weigh them against the benefits.
- Temporary stiffness or weakness during recovery
- Incomplete pain relief in a small percentage of cases
- Nerve or vessel irritation near the treatment area
- Need for follow-up therapy to fully restore function
