Key Takeaways
- Knee arthroscopy uses a small camera and precision instruments to diagnose and treat problems inside the knee joint, often in the same procedure.
- The most common reason for knee arthroscopy is a torn meniscus, but it also treats damaged cartilage, loose bodies, and inflamed joint lining.
- Compared to open surgery, arthroscopy typically means smaller incisions, less post-operative pain, and a faster return to activity.
- Recovery time varies by procedure, ranging from a few weeks for simpler repairs to several months for more involved reconstructions.
- Dr. John Redmond is a Mayo Clinic-trained orthopedic knee surgeon with extensive experience in arthroscopic knee procedures. Request an appointment if knee pain or a suspected meniscus tear has been limiting you.
What Knee Arthroscopy Is Used to Diagnose and Treat
Knee pain is one of the most common orthopedic complaints, and also one of the most variable. A problem that looks like early arthritis can turn out to be a meniscal tear. A catching sensation that seems structural can stem from loose cartilage, inflamed tissue, or a cyst that has been growing quietly for months. Knee arthroscopy gives Dr. Redmond the ability to look inside the joint directly, identify exactly what is causing the pain or limited function, and in most cases treat the problem in the same procedure.
Meniscus tears are among the most common knee injuries. According to the American Academy of Orthopaedic Surgeons, athletes in contact sports are at particular risk, though anyone at any age can tear a meniscus, and tears can also develop gradually as the tissue weakens with age. Other conditions treated with knee arthroscopy include:
- Damaged articular cartilage: Loose or torn cartilage fragments that cause pain, swelling, and catching can be removed or treated arthroscopically.
- Inflamed synovial tissue: When the synovium (the joint lining) becomes chronically inflamed, arthroscopy allows the affected tissue to be removed directly.
- Loose bodies: Small fragments of bone or cartilage floating in the joint space that interfere with movement and cause pain or catching.
- Baker's cyst: A fluid-filled cyst at the back of the knee, often associated with a meniscal tear or arthritis, that can be drained or addressed during arthroscopy.
How the Minimally Invasive Procedure Is Performed
Knee arthroscopy is performed as an outpatient procedure under local, spinal, or general anesthesia. Dr. Redmond makes two or three small incisions around the knee and inserts an arthroscope, a narrow instrument with a camera and light source, through one of them. This projects a real-time image onto a monitor in the operating room. A sterile saline solution expands the joint space to provide a clear view of the internal structures, and surgical instruments are passed through the remaining incisions to treat whatever is found.
Arthroscopic vs. Open Knee Surgery
| Knee Arthroscopy | Open Knee Surgery | |
|---|---|---|
| Incision size | Two to three small incisions | One larger incision |
| Tissue disruption | Minimal disruption to surrounding muscles, tendons, and ligaments | Greater disruption depending on the procedure |
| Post-operative pain | Generally less | Generally more |
| Infection risk | Lower | Comparatively higher |
| Typical setting | Same-day outpatient surgery for most patients | May require a longer hospital stay depending on the procedure |
For a torn meniscus specifically, arthroscopy is the standard surgical treatment. Depending on the location and pattern of the tear, Dr. Redmond can repair or carefully trim the damaged tissue to restore function and relieve pain, an approach supported by Mayo Clinic's guidance on torn meniscus treatment.
What Makes a Strong Candidate for Knee Arthroscopy
Knee arthroscopy is generally appropriate for patients with a confirmed or suspected structural problem inside the knee joint that has not responded adequately to conservative treatment such as rest, physical therapy, or injections. It is commonly performed across a wide age range, from young athletes with acute injuries to older adults with chronic knee conditions. Dr. Redmond evaluates each patient individually based on imaging, symptoms, and goals, and discusses realistic expectations before recommending any procedure.
Recovery Timeline and Return to Activity
Recovery depends on the specific procedure performed and the patient's overall health and activity level. Most patients can walk with limited assistance shortly after surgery and can resume light activity within a few weeks. Return to sport or more demanding physical activity typically takes four to six weeks for simpler procedures, such as a partial meniscectomy, and up to several months for more involved repairs. Dr. Redmond provides a structured rehabilitation plan tailored to each patient's procedure and goals.
Frequently Asked Questions
What conditions does knee arthroscopy treat?
Knee arthroscopy is used to diagnose and treat a range of structural problems inside the knee joint, including torn meniscus, damaged articular cartilage, inflamed synovial tissue, loose bodies, Baker's cysts, and more. In many cases, Dr. Redmond can diagnose and treat the problem in the same procedure.
How long is recovery from knee arthroscopy?
Most patients walk with limited assistance shortly after surgery and resume light activity within a few weeks. Return to sport or more demanding activity typically takes four to six weeks for simpler procedures and up to several months for more involved repairs.
Is knee arthroscopy the same as knee replacement?
No. Knee arthroscopy is a minimally invasive procedure used to diagnose and treat specific structural problems inside the joint, such as a torn meniscus, while preserving the natural knee. Knee replacement removes and replaces damaged joint surfaces and is typically reserved for more advanced arthritis that has not responded to other treatment.
