Symptoms of Knee Arthritis
Signs and symptoms vary for each patient but often include:
- A cracking sound when moving the knee.
- A decrease in mobility.
- A feeling of warmth in the joint.
- Pain and swelling that increases when you’re active.
- Stiffness in the knee, especially in the morning or after a long period of sitting.
Knee Arthritis Diagnosis
When a patient comes to us with knee pain, our first step is to conduct a thorough evaluation. We believe in evaluating the whole body, not just the knee. This helps to identify any other medical conditions that could impact treatment. It also helps us understand the patient’s goals and activity level, important considerations when developing a treatment plan.
The physical exam allows us to identify any abnormalities, swelling or fluid in the joints, range of motion, and muscle strength.
Diagnostic tests are also often part of the evaluation and can include x-ray, MRI, CT scan, or ultrasound.
Treatment of Knee Arthritis
Osteoarthritis of the knee is often first treated with a nonoperative treatment plan. This could include:
- Home exercises.
- Structured physical therapy.
- Walking aids.
- Injection therapy with cortisone.
- Over-the-counter or prescription medication.
- Weight loss.
The patient must understand that there is no cure for arthritis. Rather, we will find ways to help the patient manage symptoms through activity modification or recommendations on proper footwear.
If the patient does not respond to nonoperative treatment, or if other conservative methods fail to address the symptoms and alleviate pain, surgical treatment is likely the next step.
This may include minimally invasive arthroscopic techniques, which are somewhat limited in efficacy for arthritis. Other surgical options include an osteotomy, which is a procedure to realign the limb. Some patients may be a candidate for partial or total knee replacement. However, this is usually reserved for patients with severe knee arthritis when other treatments have failed.
There are three compartments in the knee, including the medial, lateral, and patellofemoral. If several are affected, a total knee replacement is the surgical treatment of choice. However, if only one compartment is affected, you may be a candidate for a partial knee replacement.
“Compared to a total knee replacement, a partial knee replacement can better restore your natural knee movement,” says Eric Chen, MD, an orthopaedic surgeon specializing in joint reconstruction with Tri Rivers Musculoskeletal Centers and director of Anterior Hip Surgery, UPMC Passavant. “Patients who undergo a partial knee replacement often say their knee feels more natural after surgery compared to a total knee replacement, which may make your knee feel more mechanical.”
Knee Arthritis Recovery and Prognosis
Postoperative physical and occupational therapy will help the patient regain range of motion and restore their independence.
The team works to ensure a seamless transition from hospital to home, including arrangements for home health care if necessary. This could include a nurse, a physical therapist, and home health equipment. Other patients may require inpatient rehabilitation or a stay in a skilled nursing facility following joint replacement.
