1. What Is Total Joint Replacement?

Total joint replacement is a surgical procedure commonly recommended for patients who suffer from severe osteoarthritis (a degenerative joint disease) or who are unable to complete daily activities due to joint pain. Total joint replacement surgery is most commonly performed on the hip, knee, and shoulder joints.

During the procedure, Dr. Henderson will remove and replace the entire diseased or damaged joint with a prosthetic implant, also known as a prosthesis. The prosthesis is composed of both metal and plastic and designed to replicate the natural movement of the joint.

2. What Is Partial Knee Replacement, and When Is It Recommended?

Partial knee replacement, also referred to as unicompartmental knee replacement, is a surgical procedure in which Dr. Henderson will only remove and replace the damaged or diseased compartment of the knee. Using a small incision, Dr. Henderson will replace the damaged compartment of the knee joint with a metal and plastic prosthesis.

Partial knee replacement is recommended for patients who only have damage to one compartment of the knee and do not benefit from more conservative treatment options, such as physical therapy or non-steroidal anti-inflammatory drugs. Because partial knee replacement procedures only require a small incision, there is less disruption of the bones, cartilage, and ligaments during surgery.

3. What Is Computer-Assisted Surgery, and How Does It Benefit Joint Replacement?

Computer-assisted surgery is a surgical technique in which the procedure is performed through a small incision and a navigation system to aid the surgeon. The assistance of the navigation system allows Dr. Henderson to isolate and treat the damaged areas of the joint more precisely than traditional open surgery.

Due to the precision of computer-assisted surgery, there is less disruption to the surrounding tissue and ligaments during surgery. In addition, patients can expect a shorter recovery time and a more natural movement of the knee post surgery. Using this surgical technique, the joint implant can be better fitted to the patient’s anatomy and alignment, which decreases the chances of dislocation.

4. Does Dr. Henderson Perform Minimally Invasive Surgery?

Yes, Dr. Henderson will use minimally invasive joint surgical techniques whenever possible. Minimally invasive joint surgical techniques can be utilized for several procedures, including partial joint replacement, total joint replacement, and joint reconstruction. In addition to the type of injury being treated, Dr. Henderson will also consider the patient’s age and fitness level when recommending minimally invasive surgery. This technique allows Dr. Henderson to perform the surgical procedure through one or two small incisions, resulting in less tissue disruption, less scarring, and a shorter hospital stay.

5. What Are the Most Common Sports Medicine Injuries?

Sports medicine injuries are most commonly caused by the overexertion or tearing of muscles and ligaments. Overexertion of muscles is the result of constant repetitive motion, such as a baseball swing. Ligament tears are the result of a ligament being stretched beyond its normal range. Ligament tears are often caused by trauma, such as a skiing accident or sports injury, and commonly occur in the ACL, the rotator cuff, and the Achilles tendon.

Because ligaments are unable to heal themselves, a surgical treatment approach is typically recommended to recover full functionality. Based on the patient’s lifestyle and the extent of the injury, Dr. Henderson many recommend a combination of physical therapy and lifestyle changes. Sports medicine techniques can also be used in the treatment of stressed or inflamed tissue, such as shinsplints or stress fractures. Sports medicine treatments are also often used to treat injuries not caused by athletic activities.
