Arthritis is one of the most common causes of joint pain in adults, especially in the knees and shoulders. These joints carry tremendous daily load, and over time, cartilage can wear down, leading to stiffness, swelling, and decreased mobility. Whether you’re beginning to notice mild discomfort or you’re living with chronic pain that limits your everyday activities, understanding arthritis early can make a significant difference in long-term outcomes.

At Plano Orthopedic & Sports Medicine Center (POSMC), our specialists diagnose and treat all forms of knee and shoulder arthritis using a personalized, evidence-based approach. Here’s what you need to know about how arthritis develops, the symptoms to watch for, and the most effective treatment options available in North Texas.

What Is Arthritis?

Arthritis refers to inflammation of the joint, but the most common form affecting knees and shoulders is osteoarthritis — a degenerative condition in which the protective cartilage that cushions the bones gradually breaks down.

Other forms include:

• Rheumatoid arthritis – an autoimmune condition

• Post-traumatic arthritis – develops after a prior injury

• Inflammatory arthritis – related to gout or other systemic conditions

No matter the cause, early evaluation is key to slowing progression and relieving pain.

Signs & Symptoms of Knee Arthritis

The knee is one of the most frequently affected joints because it supports your body weight with every step. Common symptoms include:

1. Pain with activity

Climbing stairs, walking long distances, or standing for long periods may cause increased discomfort.

2. Morning stiffness

Stiffness or difficulty bending the knee after waking or sitting for long periods is one of the earliest signs.

3. Swelling and inflammation

Fluid buildup inside the joint (effusion) can cause swelling and pressure.

4. Clicking or catching sensations

As cartilage wears down, the knee may feel unstable, catch during movement, or make popping sounds.

5. Loss of mobility

You may notice difficulty fully bending or straightening the knee.

If knee pain or stiffness is becoming a daily occurrence, it’s time to get evaluated — early treatment can slow the progression of arthritis and preserve your mobility.

Signs & Symptoms of Shoulder Arthritis

The shoulder is a complex joint that relies on smooth cartilage and fluid motion. When arthritis develops, it can significantly limit arm movement and cause persistent pain.

Common shoulder arthritis symptoms include:

• Pain when lifting the arm or reaching overhead

• Grinding or popping in the shoulder

• “Deep ache” inside the joint

• Stiffness when getting dressed or performing routine tasks

• Pain that disrupts sleep, especially when lying on the affected side

Shoulder arthritis may develop gradually, so patients often mistake early warning signs for muscle strain or fatigue.

Common Causes of Knee & Shoulder Arthritis

Arthritis can occur for several reasons, including:

• Age-related wear and tear

• Repetitive use from work or sports

• Previous injuries (dislocations, fractures, ACL tears, labral tears)

• Genetics

• Excess body weight (increases knee joint stress)

• Inflammatory diseases such as rheumatoid arthritis

A thorough examination and diagnostic imaging help determine the exact cause and severity of your arthritis.

How Arthritis Is Diagnosed

At POSMC, diagnosis typically includes:

• Physical examination to assess pain, motion, and joint stability

• X-rays to evaluate joint space and bone changes

• MRI, if necessary, to assess cartilage, tendons, and ligaments

• Review of medical history and symptoms

Early diagnosis gives patients the widest range of treatment options.

Nonsurgical Treatment Options

Most patients with knee or shoulder arthritis improve significantly with conservative care. POSMC prioritizes nonsurgical options first whenever possible.

1. Activity Modification

Avoiding high-impact activities and adjusting daily habits can reduce symptoms.

2. Physical Therapy

Strengthening the muscles around the joint reduces stress, improves mobility, and helps restore function.

3. Anti-inflammatory Medications

NSAIDs, topical creams, and joint supplements may help reduce pain and swelling.

4. Corticosteroid or Gel Injections

These can offer temporary relief and reduce inflammation in the joint.

5. Weight Management (for knee arthritis)

Even modest weight loss can significantly decrease stress on the knees.

6. Heat and Ice Therapy

Alternating heat and cold can improve stiffness and ease pain after activity.

When Surgery Becomes an Option

If conservative treatments no longer provide relief, surgical options may be considered.

For Knee Arthritis:

• Arthroscopy (select cases)

• Partial knee replacement

• Total knee replacement

For Shoulder Arthritis:

• Arthroscopic clean-out procedures

• Shoulder resurfacing

• Total shoulder replacement or reverse shoulder replacement

POSMC surgeons specialize in advanced techniques designed to restore movement, reduce pain, and help patients return to normal activities safely and efficiently.

When to See a Specialist

You should schedule an evaluation if you experience:

• Pain lasting more than 2–3 weeks

• Swelling that does not improve

• Difficulty bearing weight

• Shoulder pain that interferes with sleep

• Loss of motion or increased weakness

• Popping, catching, or grinding sensations

Early intervention can help prevent the condition from worsening and preserve joint health for years to come.
