Knee Pain and Injury

Knee injuries can be sudden or develop over time. In fact, one of the most common causes of pain in the knee are osteoarthritis, tendinitis or ligament tears.

Knee Pain

Knee injuries have accounted for more than six million visits to the ER each year. Common knee pain is caused by new or old injuries, including:


Symptoms will vary, depending on the severity of the injury, and can include:

  • Swelling, stiffness and warmth in the injured area
  • Weakness or instability
  • Popping or crunching noises
  • Inability to fully straighten your limb

More severe symptoms include:

  • Hearing a popping noise and feeling the joint give out when the injury occurs
  • Can’t walk more than four steps without significant pain
  • Can’t move the affected joint or limb
  • Have pain directly over the bones of an injured joint
  • Have numbness in any part of the injured area


Treatment for knee injuries can include:

  • Wearing a brace: Knee injuries may require a brace to stabilize the joint, and crutches to avoid putting weight on your injured leg while it heals.
  • Medication: May be needed to treat pain and inflammation. The physician may recommend injecting corticosteroids, hyaluronic acid or platelet-rich plasma directly into your joint.
  • Physical therapy: Is an effective treatment options for many knee injuries, including ACL and MCL injuries and torn meniscus. A physical therapist will teach you how to perform specific exercises and movements. Learn more about alternatives to surgery, including chiropractor, acupuncture and physical therapy.
  • Strength training: To make the muscles around your joint more stable. You may need to change your exercise routine from high-impact or pivoting exercises like running or basketball to low-impact exercise like swimming. Losing weight can also help reduce strain on your knees.
  • Surgery: Mild knee injuries will heal with treatment, while more severe injuries may require surgery. If your injury requires surgery, we can schedule your procedure with one of our surgeons or an affiliated surgeon at any one of a number of area hospitals convenient for you.

Knee Surgery

  • Arthroscopic surgery: repairing the joint damage using a fiber-optic camera and long, narrow tool inserted into small incisions.
  • Meniscectomy: trimming meniscus through tiny incisions using an arthroscope. In a total meniscectomy, the entire meniscus is removed. In a partial meniscectomy, the surgeon removes as little of the meniscus as possible. The remaining meniscus edges are smoothed so that there are no frayed ends.
  • ACL reconstruction: removing damaged ligaments and grafting segments of tendon taken from other parts of your knee or a deceased donor.
  • Partial knee replacement: the damaged portions of the knee are replaced with metal and plastic through small incisions. This is a less invasive option. Learn more about whether a partial knee replacement may be right for you.
  • Total knee replacement: Damaged bone and cartilage is cut away from the thighbone, shinbone and kneecaps and is replaced with an artificial joint made from high-grade metal, plastic and polymers.

“I saw Dr. Mirza yesterday for longstanding degenerative problems in both knees. He was excellent in figuring out the cause of my pain and limitation. After an injection in both knees, and a drain of my right knee and a Baker’s cyst in my left knee I am mobile and pain free. He is a terrific orthopedic doctor and I HIGHLY recommend him. His judgement, demeanor and skill are above excellent! I will be glad to return if I have any further problems in the future.”
