What Is a Knee Specialist Called? Your Complete Guide to Finding the Right Doctor

If you’re experiencing knee pain, you might be wondering: what is a doctor who specializes in knees called? The answer isn’t always straightforward. Several types of medical specialists treat knee conditions, each with different training, expertise, and treatment approaches. Understanding these differences can help you find the right knee specialist for your specific needs.

What Is a Knee Specialist?

A knee specialist is a physician who has advanced training in diagnosing and treating conditions affecting the knee joint. The most common types of knee specialists include orthopedic surgeons, sports medicine doctors, rheumatologists, and physiatrists. Each type of specialist approaches knee pain differently, from surgical interventions to non-surgical treatments like physical therapy and injections [1].

Types of Knee Specialists

Orthopedic Surgeons

Orthopedic surgeons are medical doctors who specialize in the diagnosis, treatment, prevention, and repair of the skeletal system and its related joints, ligaments, and muscles [2]. These specialists are qualified to perform surgeries like joint replacements and arthroscopy, which most other knee specialists cannot perform [3].

When to see an orthopedic surgeon:

• You have severe knee damage requiring surgery
• Conservative treatments have failed
• You need a knee replacement or major reconstruction
• You have fractures or significant structural damage

Sports Medicine Doctors

Sports medicine physicians focus primarily on injuries related to sporting activity, such as sprains, ligament tears, and tendonitis [3]. Many sports medicine doctors are not surgeons and have backgrounds in family medicine, internal medicine, or emergency medicine. They tend to focus more on non-surgical treatments involving physical rehabilitation or drug therapy.

When to see a sports medicine doctor:

• Your injury occurred during sports or physical activity
• You want to prevent future injuries
• You prefer non-surgical treatment approaches
• You’re an active individual looking to return to sports

Rheumatologists

Rheumatologists are medical specialists who treat arthritis, musculoskeletal conditions, and autoimmune diseases [4]. They are experts in treating inflammatory autoimmune disorders such as lupus or rheumatoid arthritis. Unlike orthopedic surgeons, rheumatologists do not perform surgery and typically offer a combination of anti-inflammatory medicines and lifestyle suggestions [4].

When to see a rheumatologist:

• Your joint pain occurred without prior injury
• You experience joint pain with fatigue, fever, rash, or stiffness
• You suspect an autoimmune condition
• You need ongoing management of chronic inflammatory arthritis

Physiatrists and Pain Management Specialists

Physiatrists are physicians who specialize in nonsurgical musculoskeletal care, also known as physical medicine and rehabilitation (PM&R) specialists [5]. Many physiatrists pursue additional training in interventional spine and sports medicine. Interventional pain management specialists are trained to identify and diagnose the root cause of pain and treat it permanently using minimally invasive and non-surgical procedures [5].

When to see a physiatrist or pain management specialist:

• You want to avoid surgery
• You need comprehensive rehabilitation
• You have chronic knee pain
• You’re seeking minimally invasive treatments

Non-Surgical Knee Treatment: Viscosupplementation

For patients seeking alternatives to surgery, viscosupplementation has emerged as an effective non-surgical treatment option. This procedure involves injecting a gel-like fluid called hyaluronic acid directly into the knee joint [6].

How Viscosupplementation Works

Hyaluronic acid is a naturally occurring substance found in the synovial fluid surrounding joints. When used as a viscosupplement in treating knee osteoarthritis, it improves symptoms by acting as a lubricant and shock absorber [6]. People with osteoarthritis have lower-than-normal concentrations of hyaluronic acid in their joints, and adding it back can facilitate movement and reduce pain.

Effectiveness of Viscosupplementation

High-quality medical studies show that viscosupplementation reduces pain in osteoarthritic knees by 40% to 62% [6]. Research suggests that viscosupplementation is most effective in the early stages of arthritis (mild to moderate), providing symptomatic relief and delaying the need for surgery.

The Importance of Precision: Fluoroscopy-Guided Injections

Not all knee injections are created equal. The accuracy of needle placement is critical to treatment success. Studies show that doctors who don’t use imaging guidance can miss the knee joint up to 30% of the time [7].

Fluoroscopy uses a continuous X-ray beam to create real-time images, helping medical teams see exactly where to place the gel inside the joint and ensuring the best results possible [7]. Healthcare professionals can guide the needle accurately and monitor the injection’s progress in real-time, enhancing effectiveness [8].

The use of fluoroscopic imaging with contrast material confirms 100% intra-articular placement of the needle, addressing the drawback of extra-articular injection placement [9].

When Should You See a Knee Specialist?

You should consider seeing a knee specialist if:

• Knee pain lasts more than two weeks [10]
• Pain interferes with daily activities or sleep
• You experience swelling, instability, or locking
• You have difficulty bearing weight on your knee
• Conservative treatments like rest and over-the-counter pain medication haven’t helped
• You hear popping or grinding sounds with pain

How to Choose the Right Knee Specialist

Choosing the right knee specialist depends on several factors:

1. The cause of your pain: Injury-related pain may benefit from sports medicine or orthopedics, while inflammatory conditions require rheumatology.

2. Your treatment preferences: If you want to avoid surgery, consider physiatrists, pain management specialists, or non-surgical orthopedic practices like Joint Relief Institute.

3. The severity of your condition: Advanced arthritis with severe joint damage may require surgical consultation, while mild to moderate arthritis often responds well to non-surgical treatments.

4. Your activity level: Athletes and active individuals may prefer sports medicine specialists who understand the demands of returning to sports.

Frequently Asked Questions

What is the difference between an orthopedic surgeon and a sports medicine doctor?

Orthopedic surgeons are qualified to perform surgeries like joint replacements and arthroscopy, while most sports medicine doctors focus on non-surgical treatments and injury prevention. Orthopedic surgeons see a wide variety of patients, while sports medicine doctors primarily treat active individuals and athletes [3].

Do I need a referral to see a knee specialist?

This depends on your insurance plan. Some plans require a referral from your primary care physician, while others allow you to self-refer to specialists. Contact your insurance provider to understand your specific requirements.

How long does viscosupplementation treatment take?

Depending on the product used, you will receive 1 to 5 shots over several weeks [6]. The injections themselves take only a few minutes, and most patients can return to normal activities the same day.

Is viscosupplementation covered by insurance?

Most insurance plans cover viscosupplementation, though some may only cover certain brands or require patients to try other treatments first [6]. At Joint Relief Institute, we accept Medicare and most insurance plans.

Can I avoid knee surgery with non-surgical treatments?

Many patients with mild to moderate knee arthritis can successfully manage their condition with non-surgical treatments like viscosupplementation, physical therapy, and lifestyle modifications. Non-surgical options are particularly effective when started early, before significant joint damage occurs.
