Overview
What is knee arthritis?
Knee arthritis is the gradual wearing down of the cartilage that cushions the knee joint, leading to pain, stiffness, and reduced mobility. Symptoms can develop gradually or after a specific injury, so early evaluation matters when function starts to decline.
Most patients with knee arthritis improve with conservative care — targeted physical therapy, image-guided injections, bracing or supportive footwear when relevant, and activity modification. When conservative care isn't enough or imaging shows structural injury that won't heal on its own, our specialists offer the next-step procedures discussed below.
Below, we walk through the anatomy involved, the symptoms and causes we most often see, how we diagnose knee arthritis, and the full range of treatment options — from the simplest to the most involved.
Patient education
Watch: Osteoarthritis of the Knee
Knee pain may keep you from being as active as you like. And it may come from a gradual breakdown of your knee's cartilage. That's a protective tissue on the ends of your bones. In a healthy knee, the bones glide smoothly against each other. But in a knee with osteoarthritis, cartilage begins to wear away. Bone rubs against bone. Bony bumps we call "bone spurs" may form.

Anatomy of the knee — femur, tibia, patella, meniscus, and the ACL/PCL ligaments.
Anatomy
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.

Diagnostics
How we diagnose knee arthritis
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 knee arthritis 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

Treatment options
How we treat knee arthritis 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.
- Physical therapy & focused strengthening
- Bracing & activity modification
- Image-guided steroid injections
- Hyaluronic acid (gel) injections
- PRP & regenerative injections
Surgical care
When neededSurgical options when needed
Minimally invasive and reconstructive procedures performed by board-certified orthopedic surgeons.
- Knee arthroscopy
- Meniscus repair or partial meniscectomy
- ACL / PCL ligament reconstruction
- Cartilage restoration (MACI, OATS)
- Partial or total knee replacement
Surgeon expertise
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
Candidacy
Am I a candidate?
If most of these match your situation, an evaluation with a knee specialist is the next step.
You may be
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
Evaluation
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, loss of bowel or bladder control, or any sign of infection (fever, increasing redness or swelling).

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
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
Specific
Knee-specific 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

FAQ
Common knee arthritis questions
- We start with a focused orthopedic exam and detailed history. X-rays are usually done in-office; MRI or ultrasound is ordered when soft-tissue detail is needed. Most patients leave the first visit with a clear diagnosis and a written plan.
- Most knee arthritis patients improve with conservative care — therapy, bracing, medication, and image-guided injections when appropriate. Surgery is reserved for cases where structural injury or persistent symptoms warrant it, and we explain every option before any decision.
- If knee pain lasts more than a few days, limits movement, or interferes with daily activities, it's time to see a doctor. Sudden injuries, swelling, or weakness should be evaluated right away.
- If you have a PPO plan, no referral is needed — book directly with any of our specialists. HMO plans require a referral from your PCP. If you are unsure, call us at (323) 264-7600 and our team will walk you through it.
