Knee pain has a way of narrowing your world. Stairs become a calculation, a weekend hike gets postponed and the activities that used to feel effortless start to feel like a risk. When rest, ice or physical therapy haven’t resolved your symptoms, knee arthroscopy offers a minimally invasive way to look inside the joint and treat what is found in the same visit.
At Angelo Mattalino, M.D., Dr. Angelo Mattalino performs knee arthroscopy for patients throughout Phoenix and Scottsdale, AZ. If knee pain has been holding you back, contact us to schedule a consultation and find out whether arthroscopy is the right next step for you.
Understanding the Knee Joint
Your knee connects the thighbone (femur), shinbone (tibia) and kneecap (patella), supported by cartilage, ligaments and tendons that work together every time you walk, run or bend your leg. The meniscus, a pair of C-shaped cartilage cushions, absorbs shock and stabilizes the joint, while ligaments like the ACL keep the femur and tibia properly aligned during movement. Articular cartilage lines the ends of the bones, allowing smooth, low-friction motion within the joint.
Because the knee bears your body weight and absorbs repeated impact, it is one of the most commonly injured joints in the body. According to UCSF Health, meniscus tears alone affect approximately one million people in the United States each year. Cartilage and ligament tissue also have limited ability to heal on their own, since much of it lacks a direct blood supply, and imaging alone does not always reveal the full extent of the damage. Arthroscopy gives Dr. Mattalino a direct, magnified view of the joint to confirm what imaging alone cannot.
What Is Knee Arthroscopy?
Knee arthroscopy is a minimally invasive procedure that allows Dr. Mattalino to examine and treat the inside of your knee joint through incisions typically smaller than a quarter inch. A thin instrument called an arthroscope, fitted with a camera at its tip, projects a real-time, magnified view of the joint onto a monitor in the operating room.
Knee arthroscopy can serve two purposes, often in the same visit. It helps confirm what is causing pain, swelling or instability when X-rays and MRI results are inconclusive, and it lets Dr. Mattalino repair, remove or reconstruct damaged tissue through those same small incisions. One peer-reviewed survey published by the Arthroscopy Association of North America estimated that 1.77 million arthroscopic procedures are performed annually in the United States, making it one of the most common tools in orthopedic surgery today.
When Is Knee Arthroscopy Recommended?
Dr. Mattalino may recommend knee arthroscopy to diagnose or treat:
- A torn meniscus, whether the goal is repair or partial removal of damaged cartilage
- A torn or damaged ACL requiring reconstruction
- Loose bodies, such as fragments of bone or cartilage, floating within the joint
- Inflamed synovial tissue lining the knee joint
- Patellar tracking problems affecting how the kneecap moves
- Wear or early degeneration of the articular cartilage
- Suspected infection within the knee joint
You may be a candidate for knee arthroscopy if you have knee pain, swelling or instability that has not improved with rest or physical therapy, if your knee catches, locks or gives way, or if imaging results suggest damage that hasn’t been confirmed through examination alone. Athletes, weekend warriors and anyone whose knee pain limits daily function are all worth a consultation with Dr. Mattalino.
Benefits of an Arthroscopic Approach
Smaller Incisions, Less Disruption
Because arthroscopy is performed through incisions typically smaller than a quarter inch, surrounding muscle and soft tissue are largely preserved. Normal knee mechanics stay protected while still allowing for an effective repair.
Greater Surgical Precision
The arthroscopic camera provides Dr. Mattalino with a magnified, real-time view of the joint, enabling more accurate diagnosis and treatment than external imaging alone. This level of detail helps him identify subtle damage that might otherwise be missed.
A Faster Return to Activity
Most patients experience less post-operative pain and a quicker return to walking, work and physical activity compared with traditional open knee surgery. Many can begin light movement earlier in the recovery process under Dr. Mattalino’s guidance.
Diagnosis and Treatment in One Visit
In many cases, Dr. Mattalino can identify and correct the problem during the same procedure, without a separate diagnostic surgery. Patients are spared an additional round of anesthesia and recovery time.
Outpatient Convenience
Knee arthroscopy is performed on an outpatient basis, allowing most patients to recover at home rather than in the hospital. Going home the same day also means healing in a familiar, comfortable environment from the start.
Lower Risk of Complications
Smaller incisions generally carry a reduced risk of infection and other surgical complications compared to open procedures. The overall experience tends to be safer, particularly for patients managing other health considerations.
Minimal Visible Scarring
Because arthroscopy relies on small portal incisions rather than a single large opening, resulting scars are typically subtle and heal well over time. Many patients find this appealing for cosmetic reasons, in addition to the functional benefits.
Knee Arthroscopy vs. Other Knee Treatment Options
The right treatment for your knee depends on the type of injury, the extent of the damage and your activity goals. ACL tears alone account for a significant share of knee surgeries; Yale Medicine reports that approximately 175,000 ACL reconstructions are performed each year in the United States.
Traditional Open Knee Surgery
Open surgery uses a larger incision to access the joint directly and may be necessary for complex reconstructions. It typically involves greater disruption of surrounding tissue, a longer recovery and a higher risk of postoperative stiffness compared to an arthroscopic approach.
Targeted Arthroscopic Procedures
Once inside the joint, Dr. Mattalino may perform a more specific arthroscopic procedure depending on what he finds, such as meniscus repair, arthroscopic partial meniscectomy, arthroscopic chondroplasty to smooth damaged cartilage, arthroscopic ACL reconstruction or loose body removal.
Non-Surgical Options
For arthritis-related pain without a structural tear, Dr. Mattalino may first recommend visco-supplementation injections or regenerative medicine injections before considering surgery.
Knee Replacement
When cartilage loss is severe and arthritis has progressed, total or partial knee replacement may be a better fit than arthroscopy. This is a more extensive procedure generally reserved for advanced joint damage rather than isolated tears or loose fragments.
What to Expect From Knee Arthroscopy
Before Your Procedure
Dr. Mattalino reviews your imaging, examines your knee and discusses your symptoms and activity goals during a comprehensive consultation. In the days before surgery, you will receive instructions on:
- Medications to pause and fasting requirements
- Arranging a ride home, since driving is not recommended after anesthesia
- Preparing a comfortable recovery space at home, with pillows for elevation and ice packs on hand
During Your Procedure
Knee arthroscopy is performed on an outpatient basis under general or regional anesthesia, depending on your health history. Dr. Mattalino inserts the arthroscope through a small incision and uses the camera feed to inspect the meniscus, ligaments, cartilage and joint lining. A sterile fluid expands the joint slightly, giving him a clearer view and more room to work with precision.
Depending on what is found, he may trim or repair torn cartilage, remove loose fragments, smooth rough surfaces or reconstruct a torn ligament before closing the incisions. Most procedures are completed within an hour, and patients typically go home within one to two hours afterward.
After Your Procedure
Recovery unfolds in stages. During the first 24 to 72 hours, rest, elevation and ice control swelling, and you may need crutches briefly. The first week brings mild to moderate swelling and stiffness that improve daily, often alongside gentle range-of-motion exercises and wound-care instructions.
By weeks two through four, most patients walk unassisted and return to light-duty work, while structured physical therapy rebuilds strength and range of motion. Around the one-month mark, more active rehabilitation begins for patients returning to sport or demanding physical work, focusing on strength training and the balance and coordination needed to prevent future injury.
Most patients regain basic daily function within four to six weeks, while a full return to sport can take two to three months, depending on what was repaired. Elite or competitive athletes may follow a longer, more gradual re-entry plan built around their specific sport.
Preparing For Knee Arthroscopy
You may be asked to:
- Stop taking certain medications or supplements that can increase bleeding
- Arrange for a friend or family member to drive you home after surgery
- Avoid food and drink after midnight the night before your procedure
- Prepare a comfortable recovery area at home with ice packs, pillows and easy-to-reach essentials
If you smoke, quitting or reducing use before surgery can improve your healing process. Staying hydrated and maintaining a balanced diet with adequate protein intake also helps your body recover more quickly.
Frequently Asked Questions About Joint Arthroscopy
Is knee arthroscopy painful?
Most patients experience soreness and swelling in the days after surgery, generally well controlled with prescribed medication, ice and elevation. Discomfort tends to improve steadily over the first week or two.
How long does the procedure take?
Knee arthroscopy is typically completed within an hour, though the exact length depends on what is found and treated. A straightforward diagnostic look inside the joint may take less time, while addressing a torn meniscus, loose fragments or ligament damage in the same visit can extend the procedure. Dr. Mattalino will give you a more specific estimate based on your imaging and symptoms before surgery.
Will I need physical therapy afterward?
Many patients benefit from structured physical therapy to rebuild strength, restore range of motion and support a safe return to activity. Dr. Mattalino will let you know whether therapy is recommended in your case.
How do I know if I need surgery instead of continuing physical therapy?
If your knee pain, swelling or instability hasn’t improved after a reasonable course of rest and physical therapy, or if imaging shows a meniscus tear, ligament damage or loose fragments, arthroscopy may be worth discussing. A consultation with Dr. Mattalino is the best way to know for sure.
