Partial Meniscectomy
A meniscus injury can significantly impair your mobility, comfort and quality of life. When a torn meniscus causes persistent pain, swelling or mechanical symptoms such as locking or catching, surgical treatment may be necessary. Partial meniscectomy is a common and effective option for meniscus tears that cannot be repaired, offering pain relief while preserving as much healthy cartilage as possible.
At Angelo Mattalino, MD in Scottsdale, AZ, Dr. Mattalino performs partial meniscectomy using advanced arthroscopic techniques designed to restore knee function and support long-term joint health. Whether your meniscus tear resulted from a sports injury or gradual wear and tear, Dr. Mattalino provides individualized care that gets you back on your feet with as little disruption to your life as possible.
What Is the Meniscus?
The meniscus is a vital structure inside your knee that helps your knee joint move smoothly while absorbing impact from daily activity and sports. Each knee has two menisci, which are positioned between the thighbone and shinbone. They act as cushions, distributing weight and reducing stress on the joint during walking, running, squatting and twisting. This balance of cushioning and stability is what allows your knee to function efficiently under load.
Because the meniscus is made of cartilage and has a limited blood supply, it is vulnerable to injury from sudden twisting motions, repetitive stress or age-related wear. When a tear occurs in an area that cannot heal on its own, the damaged tissue can disrupt the normal mechanics of your knee joint and cause pain, swelling or locking. In these cases, a partial meniscectomy is often used to remove the unstable portion of the meniscus while preserving your healthy cartilage and restoring smoother knee movement.
What Is a Partial Meniscectomy?
A partial meniscectomy is a minimally invasive arthroscopic procedure used to treat a torn meniscus when the damaged tissue cannot be repaired. During the procedure, only the torn or unstable portion of the meniscus is removed while the healthy cartilage is preserved. This approach helps relieve pain and restore smoother knee movement.
Dr. Mattalino may recommend this type of surgery based on the pattern, size and location of the meniscus tear. When repair is not possible or unlikely to heal effectively, partial meniscectomy offers a reliable way to restore comfort and mobility to the knee.
Types of Meniscus Tears Treated With Partial Meniscectomy
Certain tear patterns respond particularly well to partial meniscectomy.
Degenerative Meniscus Tears
Degenerative tears develop gradually as cartilage weakens with age or arthritis. These tears often have irregular edges that cannot be stitched together successfully. Removing the damaged portion can significantly reduce pain and improve mobility.
Complex Meniscus Tears
Complex tears involve multiple tear patterns or fragmented tissue. Repair is often not possible in these cases, and trimming the unstable segments helps restore smoother knee motion.
Radial and Flap Tears
These tears can interfere with knee mechanics and cause catching or locking sensations. Partial meniscectomy removes the unstable tissue to relieve symptoms.
Symptoms That May Indicate the Need For Knee Surgery
Meniscus tears that require surgical treatment often cause one or more of the following symptoms:
- Ongoing knee pain with activity
- Swelling or stiffness that repeatedly returns
- Locking or catching sensations
- Difficulty fully bending or straightening the knee
- A feeling that the knee may give out
- Pain with twisting, squatting or pivoting
When these symptoms interfere with your daily life or athletic activity, surgical evaluation may be appropriate.
Benefits of Partial Meniscectomy
Minimally Invasive Joint Access
Partial meniscectomy uses small incisions to access the knee joint, reducing disruption to muscles and soft tissue.
Improved Surgical Precision
The arthroscopic camera provides a clear and detailed view of the meniscus and surrounding structures, allowing accurate removal of damaged tissue.
Reduced Postoperative Discomfort
Because less tissue is disturbed, patients often experience less swelling and discomfort compared to traditional open knee surgery.
Faster Return to Daily Activities
Many patients regain functional knee movement sooner, making it easier to return to walking, work and light activity.
Preservation of Knee Function
By removing only what is necessary, partial meniscectomy helps maintain natural joint mechanics and long-term knee stability.
Supports Long-Term Joint Health
Targeted treatment reduces ongoing irritation inside the knee and helps protect remaining cartilage from further damage.
Partial Meniscectomy vs. Other Meniscus Treatments
If you are experiencing ongoing knee pain, swelling or mechanical symptoms such as catching or locking, you may be wondering how partial meniscectomy compares to other treatment options. The right approach depends on the type of meniscus tear, the location and quality of the tissue, your activity level and your long-term goals for knee function.
Meniscus Repair
Meniscus repair preserves the meniscus by stitching the torn cartilage back together so it can heal naturally. This option can be suitable for tears located in areas with good blood supply and for patients with healthy tissue quality.
While repair offers better long-term joint protection, recovery is usually longer, and weight-bearing restrictions are more strict during healing. Not all tears are suitable for repair, especially degenerative or complex tears.
Total Meniscectomy
Total meniscectomy involves removing the entire meniscus. This technique is rarely performed today. While it may relieve symptoms in severe cases where the meniscus is extensively damaged, removing all cushioning from the knee increases stress on the joint significantly. This can accelerate wear-and-tear and increase the risk of arthritis. Total meniscectomy is typically reserved for rare situations when no other option is viable.
What to Expect During Partial Meniscectomy
Before
Preparation begins with a detailed consultation. During this visit, Dr. Mattalino will review your medical history, imaging studies and current symptoms. Your knee will be examined for strength, stability and range of motion. Dr. Mattalino will explain the steps of the procedure, along with recovery expectations, so you can make an informed decision.
During
Partial meniscectomy is performed arthroscopically using minimally invasive techniques. Anesthesia is administered prior to the procedure to ensure comfort.
Dr. Mattalino makes small incisions called portals around the knee, then inserts an arthroscope to visualize the joint. Once he identifies the torn portion of the meniscus, Dr. Mattalino uses specialized instruments to carefully remove only the damaged or unstable tissue. The remaining cartilage is smoothed to promote normal joint movement.
The procedure typically takes less than one hour. Patients return home the same day.
After
Most patients go home the same day. Mild swelling, stiffness and discomfort are common and are usually managed with rest, ice, elevation and medication as recommended.
Most patients can walk on the operated leg immediately. Crutches may be used for comfort for a few days. Knee braces are typically not required.
Physical Therapy and Return to Activity
Physical therapy plays an important role in restoring knee strength, flexibility and stability after partial meniscectomy. Early therapy focuses on restoring motion and reducing stiffness. As healing progresses, strengthening and balance exercises are introduced to support safe functional movement.
Activity is gradually reintroduced based on progress and clinical guidance. The goal is to restore confidence in movement while protecting the knee during recovery.
Preparing For Partial Meniscectomy
Preparing in advance can help reduce stress and give you a smoother recovery. You may be asked to temporarily stop certain medications, arrange transportation home, and avoid eating or drinking after a specified time before your surgery is scheduled.
We also recommend setting up a comfortable recovery space at home and maintaining good hydration and nutrition leading up to the procedure.
Long-Term Effects and Considerations
Removing a portion of the meniscus reduces cushioning in the knee, which increases stress on the joint surfaces. Over time, this may increase the risk of osteoarthritis, particularly in patients with existing cartilage damage. Preserving as much healthy meniscus as possible is essential to long-term joint health.
In older patients with degenerative tears, evidence is mixed, and physical therapy alone may provide similar outcomes. Careful patient selection is critical.
Frequently Asked Questions About Partial Meniscectomy
Am I a good candidate for partial meniscectomy?
Candidacy depends on the type, location and condition of the meniscus tear as well as your symptoms and activity level. Partial meniscectomy is typically recommended when the torn tissue cannot heal or be repaired and is causing ongoing mechanical problems inside the knee.
Will removing part of my meniscus affect knee stability?
When performed appropriately, partial meniscectomy is designed to improve knee stability by removing tissue that interferes with normal joint movement. Preserving as much healthy meniscus as possible helps maintain proper load distribution and joint control.
Can partial meniscectomy be performed on both knees?
Yes. If both knees have symptomatic meniscus tears, each knee is evaluated independently. Surgery is usually performed on one knee at a time to allow safe recovery and proper rehabilitation.
Will I need additional knee treatment in the future?
Some patients may require future care depending on activity level, cartilage health and underlying joint conditions. Partial meniscectomy addresses the current tear, but ongoing joint care may include strengthening, activity modification or monitoring for arthritis.
How do I know if surgery is better than physical therapy?
This decision is based on whether symptoms are caused by mechanical disruption inside the knee. Tears that cause catching, locking or persistent pain despite therapy are more likely to benefit from surgical treatment. A thorough evaluation helps determine the most appropriate approach.
