Knee arthritis often starts with stiffness after sitting, aching after a longer walk, or knee pain when climbing stairs. As the condition progresses, pain and swelling sometimes affect work, exercise, sleep, or routine movement. The right knee arthritis treatment depends on the type of arthritis, joint damage, mobility, medical history, and personal goals. At Valley Orthopaedic Specialists, we evaluate knee pain and joint pain and consider non-surgical and surgical options based on what your knee needs.
What Does Knee Arthritis Feel Like?
Knee arthritis usually causes pain and stiffness, but symptoms vary. Some people notice a gradual ache around the knee joint. Others feel arthritis pain mainly after activity or after sitting for long periods.
Common knee arthritis symptoms include:
- Pain while walking, climbing stairs, standing, or bending the knee
- Knee stiffness after rest or first thing in the morning
- Joint swelling or tenderness
- Reduced range of motion
- Grinding, catching, or rough movement
- Pain at rest when arthritis becomes more advanced
Walking and stairs often make an arthritic knee hurt more because they place greater load through the knee joint. These knee arthritis symptoms sometimes reduce activity and weaken supporting muscles.
What Causes Arthritis in the Knee?
Osteoarthritis is the most common type of knee arthritis. Knee osteoarthritis develops as the articular cartilage covering the ends of the bones gradually wears down. As cartilage wears, the joint space narrows, damaged joint surfaces absorb more stress, and bone spurs often develop.
The cartilage and menisci inside your knee cushion the joint as you walk, bend, stand up, and climb stairs. They work like shock absorbers between the thigh bone, shin bone, and kneecap. As that cushioning wears down, everyday movement places more stress on the knee joint, which can make pain and stiffness more noticeable.
Knee osteoarthritis becomes more common after age 50, although younger patients sometimes develop it after an injury or because of other risk factors. Age, excess body weight, previous knee injuries or surgery, and genetics are among the recognized risk factors for knee osteoarthritis. Previous ligament or meniscus injuries, fractures, extra weight, and certain health conditions also contribute to joint damage over time.
Other forms include rheumatoid arthritis, an autoimmune disease that often affects multiple joints, posttraumatic arthritis after injury, and inflammatory arthritis such as gout or lupus. Rheumatoid arthritis and other inflammatory arthritis conditions require a different treatment approach from osteoarthritis.
How Do We Diagnose Knee Arthritis?
An orthopaedic evaluation starts with your medical history and a physical examination. We check where pain occurs, when it worsens, whether you have pain and swelling, and whether the knee has lost strength or flexibility. The knee exam also checks tenderness, alignment, stability, and range of motion.
Imaging tests show what is happening inside the knee joint. X-rays often reveal reduced joint space, bone spurs, alignment changes, or other signs of an arthritic knee and magnetic resonance imaging sometimes gives us more detail about cartilage, menisci, ligaments, and other soft tissues.
Blood tests or joint-fluid tests sometimes support an accurate diagnosis when symptoms suggest rheumatoid arthritis, gout, infection, or another inflammatory condition. Once we have knee arthritis diagnosed, we match treatment to the condition.
Which Knee Arthritis Treatment Options Relieve Pain?
Most patients start with non-surgical care. Exercise, weight management, medication, physical therapy, knee injections, and assistive devices often reduce pain and improve function depending on the diagnosis and symptom severity.
A treatment plan often includes:
- Strengthening and low impact exercise
- Physical therapy to improve strength, flexibility, balance, and knee range of motion
- Weight management to reduce stress on the knee joint when extra weight adds load
- A brace, cane, or shoe inserts when appropriate
- Topical or oral nonsteroidal anti-inflammatory drugs (NSAIDs)
- Knee injections for selected patients
A physical therapist selects specific exercises based on strength, mobility, pain pattern, and physical examination. Working with a physical therapist gives you a way to increase activity and reduce pain. Low impact exercise such as walking, cycling, swimming, or tai chi are often included in that plan.
If body weight contributes to symptoms, reducing extra weight lowers the load the knee carries. If you need to lose weight, discuss an approach with a healthcare professional that fits your overall health.
Topical NSAIDs often relieve pain with fewer gastrointestinal side effects than oral medicines because they create less systemic exposure. Oral NSAIDs also reduce pain and reduce inflammation, but gastrointestinal, kidney, cardiovascular, and other health conditions affect whether they suit a particular patient. Over the counter medicines still carry risks, so it’s recommened to discuss regular use with a healthcare professional.
Regular exercise, weight management, and appropriate pain-control strategies form an important part of knee osteoarthritis treatment.
When Do Knee Injections Become A Treatment Option?
Knee injections sometimes are a treatment option when pain continues despite exercise, medication, or physical therapy.
Corticosteroid injections reduce inflammation inside the knee joint and reduce pain for some patients for a limited period. Hyaluronic acid injections place a gel-like substance into the knee joint. Hyaluronic acid contributes to joint lubrication, and some patients report less pain after treatment.
Routine hyaluronic acid injections for knee osteoarthritis are not generally recommended because evidence has not shown consistent benefit. An individual evaluation remains important when deciding whether an injection fits your symptoms and previous treatment.
When Does Knee Arthritis Treatment Include Surgery?
Surgery is a treatment option when significant symptoms continue despite appropriate non-surgical treatment and knee arthritis starts limiting walking, stairs, work, sleep, or other daily activity.
An X-ray alone doesn’t determine whether someone needs knee replacement surgery. An orthopedic surgeon considers knee pain, joint damage, mobility, health history, previous treatment, and personal goals.
Depending on the knee, surgical management includes several options:
- Knee osteotomy: The surgeon changes bone alignment to shift weight away from the damaged area. Surgeons often reserve knee osteotomy for selected younger patients.
- Arthroscopic surgery: Arthroscopic surgery uses small incisions and a camera for specific meniscus or cartilage problems. Those small incisions do not make arthroscopic surgery a routine treatment for knee osteoarthritis.
- Partial knee replacement: Partial knee replacement replaces one damaged compartment when arthritis remains limited to that area.
- Total knee replacement: Total knee replacement replaces damaged joint surfaces when advanced arthritis affects larger areas of the knee.
Knee replacement surgery is a form of joint replacement surgery. During replacement surgery, the orthopedic surgeon removes damaged joint surfaces and positions artificial joint components. A knee replacement surgery consultation compares partial and total replacement based on the pattern of arthritis.
Knee replacement surgery is not suitable for every patient. Some people continue non-surgical treatment, while others consider knee replacement surgery when knee pain and limited function persist. An evaluation determines whether replacement surgery belongs in the plan.
When Should You See a Doctor for Knee Arthritis?
Consider an orthopaedic evaluation when knee pain or stiffness keeps returning, joint swelling persists, walking distance changes, climbing stairs becomes difficult, or joint pain interferes with work, exercise, sleep, or daily movement.
An evaluation is also recommended when over the counter medicines or self-directed exercise no longer relieves pain enough, or when other symptoms make it unclear whether the problem comes from knee arthritis, a men0iscus injury, a ligament problem, or another condition.
For patients in Shelton, Oxford, Fairfield, and surrounding Connecticut communities, Valley Orthopaedic Specialists provides orthopaedic evaluation along with on-site X-ray imaging, injections, physical therapy, and surgical treatment when appropriate.
How Do You Choose the Right Treatment?
Knee arthritis does not affect every patient in the same way. The next step is identifying the type and extent of arthritis, understanding how pain affects movement, and matching care to your symptoms, health history, and goals.
If knee pain is changing how you walk, use stairs, sleep, work, or stay active, schedule an orthopaedic evaluation with Valley Orthopaedic Specialists. Our team reviews your symptoms and imaging and discusses knee arthritis treatment options at our Shelton, Oxford, or Fairfield offices.
