Living with chronic knee pain can feel like an uphill battle, especially in a city like Pittsburgh where navigating hills, steps, and uneven terrain is part of daily life. Whether you are struggling to walk through Point State Park or finding it difficult to climb the stairs in your own home, knee pain can shrink your world and limit your independence.
Many patients wonder if their discomfort is just a natural part of aging or if it signals a more serious issue that requires intervention. Understanding the threshold between manageable discomfort and a condition requiring surgery is crucial for your long-term health.
Recognizing the Signs You Need Knee Replacement
Arthritis is the most common cause of chronic knee pain and disability. While osteoarthritis is the usual suspect, rheumatoid arthritis and traumatic arthritis can also degrade the joint over time. But pain alone isn't the only marker. There are specific functional limitations and physical symptoms that orthopaedic surgeons look for.
Here are the common signs you need knee replacement surgery:
Severe Pain that Limits Daily Activities
If pain dictates your schedule, it might be time to consider surgery. This includes pain that limits your ability to walk more than a few blocks without significant discomfort or the need for a cane or walker. If you find yourself avoiding social events, grocery shopping, or hobbies you once loved because you are afraid of the pain, your condition is affecting your quality of life.
Pain While Resting
Most mechanical joint pain occurs during movement. However, if you experience moderate to severe knee pain while resting, or if pain wakes you up at night, it indicates severe joint degeneration. This 'resting pain' suggests that the cushioning cartilage has worn away significantly, causing bone-on-bone friction even without the pressure of weight-bearing.
Chronic Inflammation and Swelling
Occasional swelling after a long hike or vigorous exercise is normal. However, chronic swelling that does not improve with rest, ice, or medication is a warning sign. You might notice your knee looks larger than the other or feels warm to the touch regularly.
Knee Deformity
As arthritis progresses, the knee can become unstable. You might notice a bowing in or out of your leg. This physical deformity changes your gait and can lead to hip or back pain as your body tries to compensate for the instability.
Stiffness and Loss of Motion
If you are unable to bend or straighten your knee completely, simple tasks become difficult. This might manifest as difficulty getting in and out of a car, putting on socks, or sitting in a low chair.
Exploring Knee Pain Treatment: Non-Surgical Alternatives
Surgery is rarely the first step. At Greater Pittsburgh Orthopaedic Associates, we believe in exhausting conservative knee pain treatment options before recommending a total joint replacement. We want to ensure that surgery is the absolute right choice for your specific anatomy and lifestyle.
Below is a comparison of common conservative treatments we may recommend before discussing surgery:
| Treatment Option | Purpose | Best For |
|---|---|---|
| Physical Therapy | Strengthens muscles around the knee to reduce joint load. | Patients with mild to moderate arthritis and stiffness. |
| Weight Loss | Reduces the mechanical force placed on the knee joint. | Patients where BMI contributes significantly to joint stress. |
| Anti-inflammatory Meds | Reduces swelling and manages pain levels. | Managing flare-ups and day-to-day discomfort. |
| Corticosteroid Injections | Powerful anti-inflammatory shots directly into the joint. | Providing short-to-medium term relief from acute pain. |
| Viscosupplementation | Injects hyaluronic acid to lubricate the joint. | Patients with mild to moderate osteoarthritis seeking better mobility. |
| Bracing | Provides external stability and unloads pressure. | Patients with instability or specific alignment issues. |
If you have tried these methods for six months or more without significant relief, the conversation may shift toward surgical solutions.
When Is Knee Replacement Necessary?
Determining when is knee replacement necessary is a personal decision made between you and your orthopaedic surgeon. There is no specific age requirement; there is only a requirement of need. Whether you are 55 or 85, if your knee is preventing you from living a healthy, active life, you may be a candidate.
The 'right time' usually occurs when the pain becomes unmanageable despite non-surgical efforts. You should ask yourself:
- Is the pain continuous?
- Do medications no longer provide relief?
- Is my mobility significantly restricted?
- Is my mental health suffering due to chronic pain?
If you answer 'yes' to these questions, delaying surgery might actually be detrimental. Prolonged inactivity due to knee pain can lead to weight gain, loss of muscle mass, and cardiovascular issues. Furthermore, waiting too long can sometimes make the surgery more complex if the deformity becomes severe or the muscles atrophy excessively.
What Does a Total Knee Replacement Look Like?
Many patients are anxious because they don't understand the procedure. Asking 'what does a total knee replacement look like?' is a great way to demystify the process.
In a knee replacement, the surgeon does not actually remove the entire knee. Instead, they resurface the damaged parts of the bone.
- Preparation: The damaged cartilage and a small amount of underlying bone are removed from the ends of the femur (thigh bone) and tibia (shin bone).
- Implantation: Metal components are positioned to recreate the surface of the joint. These may be cemented or press-fit into the bone.
- Resurfacing the Patella: The undersurface of the kneecap (patella) is cut and resurfaced with a plastic button, depending on the case.
- Spacer Insertion: A medical-grade plastic spacer is inserted between the metal components to create a smooth gliding surface, replicating the function of healthy cartilage.
Modern advancements have made this procedure highly successful, with many patients returning to low-impact activities like walking, swimming, and golfing pain-free.
How We Evaluate Patients
If you are searching for a 'knee specialist near me' in the Pittsburgh area, it is vital to choose a practice that conducts a comprehensive evaluation. At Greater Pittsburgh Orthopaedic Associates, our evaluation process is thorough and patient-centric.
Medical History Review
We start by listening. We review your general health, the history of your knee pain, previous injuries, and the treatments you have already tried. We want to know how your knee pain affects your specific lifestyle goals.
Physical Examination
Your surgeon will assess the range of motion in your knee, checking for stability and alignment. We will observe you walking, sitting, and standing to see how your knee functions under weight-bearing conditions.
Advanced Imaging
X-rays are the standard tool to visualize bone-on-bone contact, bone spurs, and deformity. In some complex cases, an MRI or CT scan may be utilized to get a detailed look at the soft tissues and bone structure.
We combine all this data to determine if you are a candidate. We prioritize education, ensuring you understand exactly why surgery is (or isn't) recommended and what the recovery road looks like.

Frequently Asked Questions
How long is the recovery time for knee replacement?
Most patients are up and walking with assistance the day of surgery. Physical therapy begins almost immediately. While you can typically return to most normal daily activities within 3 to 6 weeks, full recovery and maximum benefit from the surgery can take 6 months to a year.
Is there an age limit for knee replacement surgery?
There is no absolute age limit. Recommendations are based on a patient's pain and disability, not their age. Most patients are between 50 and 80, but surgeons evaluate patients individually based on overall health and bone quality.
How long do artificial knees last?
Modern knee replacements are very durable. Studies suggest that more than 90% of modern total knee replacements are still functioning well 15 years after the surgery. With proper care and by avoiding high-impact activities (like running), your implant can last for decades.
Will I need physical therapy after surgery?
Yes, physical therapy is a critical component of your recovery. It helps restore range of motion and strengthens the muscles around the new joint. Commitment to your PT regimen is one of the biggest predictors of a successful surgical outcome.
Can I have both knees replaced at the same time?
Bilateral knee replacement is possible but carries higher risks and a more challenging recovery. Your surgeon will evaluate your overall health and cardiovascular condition to determine if you are a candidate for simultaneous surgery or if staged surgeries would be safer.
