Knee Pain Without Surgery and Persistent Pain After Knee Replacement: What Interventional Pain Management Can Offer

Do you struggle with pain or limited mobility while walking or bending, even after your knee surgery? You're not alone! A common and often overlooked clinical problem is constant knee pain, even after surgery. In fact, some patients continue to experience pain after knee replacement due to nerve-related pain, inflammation, soft tissue irritation, or persistent sensitization of pain pathways.

At Groth Pain and Spine, our focus is on identifying the true source of pain and providing targeted treatments that go beyond medications and surgery when appropriate.

Common Causes of Knee Pain Before and After Surgery

Knee pain is not always caused by a single structure. Pain can originate from the joint, surrounding soft tissues, or the nerves that transmit pain signals.

Knee Osteoarthritis

Osteoarthritis is the most common cause of knee pain before surgery. It occurs when cartilage within the joint gradually wears down.

What Are the Symptoms?

• Pain with walking or standing

• Morning stiffness

• Swelling

• Reduced range of motion

• Pain that worsens with activity

Constant Pain After Knee Replacement

Although knee replacement is highly effective, many patients continue to experience pain after surgery. Possible causes may include:

• Residual nerve pain around the joint

• Scar tissue formation

• Persistent inflammation

• Altered biomechanics

• Central sensitization (heightened pain processing)

• Component-related irritation (less common)

This condition is often referred to as persistent post-surgical knee pain.

Meniscus, Ligament, and Tendon Disorders (Pre-Surgery)

Before surgery, knee pain may also come from meniscus degeneration or tears, ligament sprains or instability, and tendon irritation such as patellar tendinopathy.

Referred Pain

Knee pain may also originate from the hip, spine, or nerve pathways rather than the knee itself. This is important both before and after surgery.

How Does Interventional Pain Management Evaluate Knee Pain?

At Groth Pain and Spine, evaluation focuses on identifying whether pain originates from the joint, surrounding structures, or nerve pathways. The evaluation process includes a step-by-step approach.

1. Detailed History

We assess main factors, including:

• When pain began or changed after surgery

• Type of surgery performed (if applicable)

• Response to prior injections or therapy

• Activity-related triggers

• Functional limitations

2. Physical Examination

This includes:

• Range of motion testing

• Joint tenderness assessment

• Stability evaluation

• Scar and soft tissue assessment in post-surgical patients

• Gait and alignment analysis

3. Imaging Review

This includes X-rays for arthritis or prosthesis evaluation, MRI (when applicable, pre-surgery or for soft tissue evaluation), and post-operative imaging when indicated.

Non-Surgical and Post-Surgical Treatment Options for Knee Pain

Interventional pain management offers a range of minimally invasive treatments for both patients who have not had surgery and those with persistent pain after knee replacement.

Corticosteroid Knee Injections

Steroid injections reduce inflammation within the knee joint and may help both degenerative and inflammatory pain states. They may be used before surgery for arthritis flare-ups and after surgery in select cases of inflammation (carefully selected patients).

Viscosupplementation (Hyaluronic Acid Injections)

These injections improve joint lubrication and may reduce stiffness and discomfort in patients with osteoarthritis who are not yet ready for surgery.

Genicular Nerve Blocks

The knee joint is innervated by small sensory nerves known as genicular nerves. These nerves continue to transmit pain signals even after knee replacement in some patients.

Genicular nerve blocks can:

• Identify nerve-mediated pain

• Help predict response to longer-term treatments

• Provide temporary pain relief

Radiofrequency Ablation of Genicular Nerves

For patients who respond to diagnostic blocks, radiofrequency ablation (RFA) can be used to interrupt pain signals from the genicular nerves.

This treatment may be beneficial for:

• Chronic knee osteoarthritis pain before surgery

• Persistent pain after knee replacement

• Patients who are not surgical candidates or who have exhausted surgical options

How Does It Help?

• It provides longer-lasting pain relief compared to injections

• Patients experience improved walking and standing tolerance

• It results in reduced medication dependence

• It's an outpatient, minimally invasive procedure

Peripheral Nerve Stimulation (PNS) of the Genicular Nerves

PNS is an advanced neuromodulation option for chronic knee pain. This treatment may be beneficial for constant pain after knee replacement, or patients who received only partial relief from radiofrequency ablation, and as a reversible, non-destructive treatment option. The therapy involves placing small leads near the genicular nerves that deliver gentle electrical stimulation to modify pain signaling.

How Does It Work?

• Significant reduction in chronic knee pain

• Improved mobility and function

• Reversible and adjustable therapy

• No permanent nerve destruction

• Option for complex post-surgical pain syndromes

Platelet-Rich Plasma (PRP) Therapy

PRP may be considered in select patients with degenerative changes or soft tissue irritation. PRP uses the body's own cells to promote tissue healing.

Physical Therapy and Rehabilitation

Rehabilitation remains a major part of treatment before and after surgery. It mainly focuses on improving joint stability & range of motion, strengthening surrounding musculature, and restoring functional movement patterns.

When Knee Pain Does NOT Require Surgery?

Many patients are referred for surgical evaluation before all non-surgical options are explored. Interventional pain management may be appropriate in the following situations:

• Pain persists even after conservative care

• Arthritis is mild to moderate

• Surgery is being delayed or avoided

• Pain continues after knee replacement without a clear surgical cause

• The patient is not a candidate for additional surgery

When Surgery May Still Be Necessary?

Surgery may still be required in cases of:

• Severe end-stage osteoarthritis

• Major joint deformity

• Mechanical instability

• Prosthesis-related mechanical failure or loosening

Even in these cases, interventional treatments can play an important role in pain control before or after surgical intervention.

What Patients Ask About Knee Pain?

Why does my artificial knee still hurt?

Dealing with knee pain after knee replacement surgery can be very frustrating, but it is actually a common issue. While surgery replaces the worn-out bone, it does not always fix the hyperactive nerves around the joint. Your body can develop scar tissue, ongoing inflammation, or a condition where the surrounding nerves stay irritated and keep firing pain signals to your brain. When this happens, the issue is usually nerve-related rather than a problem with the new implant itself.

Can chronic knee pain be treated without surgery?

Yes, you have many excellent options for knee pain without surgery. Many people assume that severe arthritis means they automatically need a joint replacement, but advanced chronic knee pain treatment can delay or completely avoid the operating room. A specialized knee pain doctor in Long Island can use targeted therapies to reduce inflammation and block pain pathways, helping you walk and climb stairs comfortably again.

What is a genicular nerve block, and how does it help?

A genicular nerve block is a quick, diagnostic injection that targets the small sensory nerves surrounding your knee joint. These nerves are responsible for sending pain messages to your brain. By temporarily numbing them, your knee pain specialist can decide if these specific nerves are the main source of your daily misery. If the injection provides relief, it proves that a longer-lasting treatment, like heating the nerves to quiet them down, will work well for you.

Takeaway

If you are struggling with knee pain that has not improved with conservative care or even after surgery, interventional pain management can really help. It includes a detailed evaluation to identify the source and guide effective treatment options aimed at restoring function and improving quality of life.
