Orthopaedic Surgery Cures Arthritis: How Surgeons Tailor Joint Replacements

Orthopaedic Surgery stands out in medicine because it can truly cure a condition rather than only manage it. When arthritis destroys the cartilage in a joint, that tissue is gone. What orthopaedic surgeons do is replace the damaged surfaces, removing the arthritis and restoring joint function. Southwest Michigan Center for Orthopaedics & Sports Medicine’s Daniel Sohn, MD explains why in this video.

Why orthopaedic surgery is unique

Many medical specialties focus on long-term management of symptoms and disease progression. Orthopaedic Surgery is different in that joint replacement often eliminates the source of pain and disability. Replacing a worn-out joint removes the arthritic surfaces and, for most patients, restores reliable, pain-free movement.

What “cure” really means for arthritis

Arthritis is the loss of cartilage. You cannot “take out” something that has already been lost. Instead, our surgeons remove the damaged joint surfaces and replace them with artificial components. Once the replacement is in place, the arthritic joint is gone.

That said, curing the joint does not automatically fix every symptom a person has. Pain and gait abnormalities can have multiple causes. If gait does not normalize after a successful joint replacement, it is often due to other problems such as spine disease or issues in the opposite limb.

The connections between hip, knee, and back

The body is a linked mechanical system. The hip, knee, and spine influence one another. A painful or stiff hip can change how someone stands and walks, which in turn affects the knee and low back. Similarly, spinal alignment or nerve problems in the back can produce gait changes that persist even after a joint is replaced.

Recognizing these interconnections is essential. Successful outcomes require looking beyond the arthritic joint and considering the whole kinetic chain.

How surgeons tailor orthopaedic surgery to each patient

Personalization is a core principle of modern Orthopaedic Surgery. Surgeons adapt the plan and implants based on the patient’s anatomy, activity level, and problems elsewhere in the body—especially the spine.

• Preoperative evaluation: Assess spine alignment, hip and knee mechanics, and gait. Imaging and a thorough history reveal whether back disease or knee problems contribute to symptoms.
• Implant choice and orientation: For patients with prior back problems, hip implants may be positioned differently to reduce the risk of dislocation and to provide a stable, functional range of motion.
• Surgical technique: Soft tissue balancing and component positioning are adjusted to match the patient’s unique anatomy and compensatory patterns developed over years.
• Rehabilitation plan: Rehab is targeted not just at the replaced joint but at restoring overall gait patterns. Physical therapy may include spine mobility work or contralateral limb conditioning.

What to expect after surgery

After joint replacement, many patients experience dramatic pain relief and improved function because the arthritic joint has been replaced. However, recovery is a process. If gait or persistent discomfort remains, further evaluation of the spine and other joints is appropriate.

“We’re exchanging a sensitive joint with a metal and plastic joint, which obviously has no sensation,” says Dr. Sohn. “The key is to place the metal and plastic joint in a position that offers the best biomechanics the best range of motion and the best balance to provide long-term solution to pain and function.”

The goal of Orthopaedic Surgery is a stable, non-dislocating joint that allows safe, functional movement. When surgeons account for the whole musculoskeletal system, outcomes improve and complications decrease.

Practical takeaways

1. Arthritis is loss of cartilage. Replacing the joint removes the arthritic surfaces and can be curative for that joint.
2. Persistent gait problems after replacement are often due to other sources such as the spine or opposite limb.
3. Surgeons tailor joint replacements—implant choice, orientation, and technique—especially when back problems are present.
4. Comprehensive evaluation and rehabilitation that address the entire kinetic chain yield the best long-term results.

FAQ

Does Orthopaedic Surgery really cure arthritis?

When arthritis is limited to cartilage loss in a joint, replacing the joint removes the diseased surfaces. That replacement functionally cures the arthritic joint by restoring smooth, pain-free motion where cartilage once was lost.

Why doesn’t my gait normalize immediately after a joint replacement?

Gait is influenced by multiple structures. Long-standing compensations, spine problems, or issues in other joints can persist after the replaced joint is fixed. Assessment of the spine and surrounding joints helps determine the cause and guide further treatment or therapy.

How do surgeons change a hip replacement if I have back problems?

Surgeons may alter implant positioning and choose components that provide greater stability across the range of motion. The exact changes depend on spinal mobility and alignment so the replaced hip works safely with the spine.

Can arthritis be removed like a tumor?

Arthritis represents tissue loss, not a distinct mass to excise. The practical approach is to replace the damaged joint surfaces so the arthritic condition is eliminated and function is restored.
