Frequently Asked Questions about Knee Arthritis
What are the most common causes of knee pain?
Knee pain can have a wide range of causes. Some of the most common include:
- Arthritis
- Traumatic injuries (sprains, tears, fractures)
- Overuse/repetitive stress injuries
- Tendinitis
- Bursitis
Risk factors for the development of knee pain include aging, obesity, and participation in activities that put strain on the knee joint.
Can knee pain be treated without surgery?
Yes, many types of knee pain can be treated effectively without surgery. At Modern Orthopaedics of New Jersey, our physical medicine doctors have advanced training in non-surgical treatment techniques and always use the least invasive treatment approach possible. Non-surgical treatment options for knee pain can include rest and activity modifications, physical and occupational therapy, bracing, lifestyle changes, steroid injections, and more.
When should I consider a knee replacement?
If knee pain is severe, persistent, hasn’t responded to non-surgical treatment, and is affecting your mobility and quality of life, it may be time to consider knee replacement surgery. At Modern Orthopaedics of New Jersey, one of our leading joint replacement specialists will work closely with you to determine whether a partial knee replacement or total knee replacement is the best option moving forward.
How effective are injections for knee arthritis?
The effectiveness of injections for knee arthritis can vary depending on the type of arthritis, the type of injection, the severity of the condition, and the way the patient’s body responds to the injected medication. Corticosteroid injections typically provide short-term pain relief that lasts anywhere from a few weeks to a few months and must be repeated at regular intervals. Schedule an appointment today to explore steroid injections as a possible treatment option for your knee pain.
How long does it take to return to sports after a knee injury?
The length of time it takes to return to sports after a knee injury depends on the type and severity of the injury, the overall health of the patient, and the patient’s commitment to proper rehabilitation. A minor strain or sprain may heal within a week or two, while a fracture or torn ACL may require months of treatment and active rehabilitation.
Are minimally invasive knee surgeries available?
Yes. At Modern Orthopaedics of New Jersey, many of our orthopedic surgeries are performed using minimally invasive techniques – including arthroscopy and robot-assisted surgery. The benefits of these techniques include smaller incisions, reduced pain, faster recovery, and lower risk of infection and other complications.
How do I know if my knee injury needs medical attention?
You should seek medical attention for a knee injury if:
- Pain/swelling/bruising is severe
- Weight-bearing is difficult or impossible
- Range of motion is limited
- Symptoms are persistent (don’t resolve with rest)
- Discomfort is affecting your daily routine
If you’re unsure whether or not to seek medical treatment, it’s always best to err on the side of caution and have your knee joint evaluated as soon as possible.
What is the recovery time for common knee surgeries?
Recovery time following knee surgery can vary greatly depending on the procedure being performed, the age and overall health of the patient, and the specifics of the case. Full recovery after a knee arthroscopy usually takes about 4 to 6 weeks, while full recovery after an ACL knee reconstruction or knee replacement surgery is usually closer to 12 months. It’s best to speak directly with your surgeon for a more accurate estimate based on the surgery you are undergoing.
What are the risks and benefits of knee replacement surgery?
The major benefits of knee replacement surgery include:
- Pain relief
- Improved mobility
- Better quality of life
The potential risks associated with knee replacement surgery include:
- Infection
- Implant problems
- Injury to nerves or blood vessels
- Stiffness or limited range of motion
The benefits of knee replacement surgery typically outweigh its risks – especially in cases where knee pain is severe and disabling. Schedule an appointment today with one of our board-certified specialists to learn more!

Imaging tests commonly used to diagnose knee problems include X-ray, ultrasound, MRI, and CT scan. Your specialist will determine which, if any, imaging tests to order after an initial consultation and in-depth physical examination.
How can I prevent knee injuries in the future?
Key recommendations for preventing knee injuries now and in the future include warming up consistently, wearing proper footwear, strengthening the thighs, hamstrings, and hips, improving flexibility and balance, maintaining a healthy weight, and avoiding overuse of the knee joint.
