If you live in Pittsburgh or the surrounding region and suffer from persistent knee pain, a meniscus tear could be to blame. While many people assume that any tear “seen on an MRI” requires surgery, that’s not always the case. In fact, meniscus tears are a common knee injury that can frequently be treated through non-surgical or regenerative approaches—often with better outcomes and fewer risks than surgery.
In this comprehensive guide, we’ll explore everything you need to know about meniscus tears: what they are, how they happen, the different types, and the top non-surgical treatment options available at Regenexx Pittsburgh.
Meniscus tears are a common cause of knee pain that can often be treated without surgery.
What is a meniscus?
The meniscus is a fibrocartilage structure that sits on top of the tibia, or lower leg bone. It serves as a kind of “shock absorber” between your thighbone (femur) and shinbone (tibia). Each knee has two menisci: a medial meniscus on the inside of the knee, and a lateral meniscus on the outside of the knee. Each one is shaped like a C, and acts like a shock absorber, lending the knee cushion and support.
Together, they provide cushion and support for the knee joint, helping with shock absorption and overall joint stability.

Meniscus Tear Causes and Risk Factors
Meniscus tears can result from:
- Sports or high-impact activities (twisting, pivoting, or sudden stops)
- Aging and wear-and-tear, leading to degenerative changes
- Occupational stresses, such as repetitive bending, squatting, or standing for long hours
- Obesity or poor biomechanics, placing extra stress on knee cartilage
How common are meniscus tears and what do they feel like?
Meniscus tears are quite common. In fact according to the British Journal of Sports Medicine, if you were to get MRI’s of people over the age of 35, most of them are likely to have a meniscus tear, many without any symptoms [1]. Your meniscus can tear due to a specific injury from things like sports, twisting, deep knee bending, rotating, or other high-intensity activities. It can also be degraded over time, with the natural wear-and-tear as you age.
Signs & Symptoms of a Meniscus Tear
Common symptoms include:
- Pain (inside, outside, or back of the knee)
- Swelling and/or stiffness
- Catching or locking of the knee joint
- Difficulty bending or fully extending the knee
- Limping or feeling of instability
A well known orthopedic surgery resource, Johns Hopkins Medical describes what meniscus tears feel like in this way: Symptoms of a meniscus tear are pain in the knee joint (usually on the inside, outside, or back), swelling, catching or locking of the knee joint, inability to fully extend or bend the knee, and limping [2].
Should you get surgery?
It is a common belief that if you can see a meniscus tear on an MRI, then it will require surgery, but surgery may not be the best option. About 96% of meniscus surgeries that occur are meniscectomies. These surgeries do not repair the meniscus, but rather remove the torn section. Despite most being called “meniscus repairs”, surgeries that actually repair the torn fibrocartilage are much rarer.
The majority of research indicates that most of these surgeries do not work. Not only will surgery often not work, it will also speed up the arthritic process leading to severe arthritis much quicker that what normally would have occurred. A 2013 study found that physical therapy had the same outcomes as surgery, while another study found the same results from patients who underwent meniscus surgery as those who underwent a fake procedure [3, 4]. And in the long term, surgery can actually be harmful to the knee. Evidence suggests that removing sections of the meniscus puts more stress and wear on the cartilage and leads to arthritis progressing much faster [5, 6]. Patients who underwent meniscal surgery were also 2.5 times more likely to require a knee replacement, than those who went without surgery [7, 8]. Surgery is often the go-to treatment for meniscus tears, but there are often better options.
Why Consider Non-Surgical Options?
Meniscus surgery, particularly meniscectomy (removal of the torn section), has long been the default solution. However, current research increasingly supports conservative and regenerative approaches first, especially since most meniscus surgeries don’t actually repair the tissue—they simply remove it. Here’s why non-surgical options are worth exploring:
- Potential for Better Long-Term Outcomes: Studies show that many people who undergo meniscus surgery fare no better than those opting for physical therapy alone [3, 4].
- Faster Progression of Arthritis: Removing sections of the meniscus can speed up joint degeneration. Studies indicate that surgery can put increased stress on the knee cartilage, leading to faster onset of arthritis [5, 6].
- Higher Risk of Future Knee Replacement: Research has shown that people who undergo meniscal surgery are 2.5 times more likely to need a total knee replacement down the road [7, 8].
Should You Get Surgery? Weighing the Pros and Cons
It’s natural to assume that if an MRI detects a meniscus tear, surgery is a must. However, according to the British Journal of Sports Medicine, meniscal tears are extremely common in people over 35—often with no symptoms at all [1]. The vast majority (about 96%) of “meniscus surgeries” involve cutting out the torn portion rather than truly repairing it. Actual meniscus repairs are much rarer and typically only recommended for certain tear types.
Key Takeaway: Surgery may be necessary in some specific situations (e.g., severe mechanical locking or a “bucket-handle” tear). But in many cases, conservative treatments can yield comparable or better outcomes—minus the surgical risks.
Non-Surgical Treatment Options
Physical Therapy & Rehabilitation
A structured physical therapy (PT) program often serves as the first-line treatment for a torn meniscus. PT focuses on:
- Strengthening surrounding muscles (particularly the quadriceps and hamstrings)
- Improving range of motion and flexibility
- Correcting biomechanical issues that may exacerbate knee stress
By stabilizing the knee joint and improving gait mechanics, many patients see significant pain relief and improved function without any surgical intervention.
Steroid Injections
Some clinics in Pittsburgh may offer a corticosteroid injection if physical therapy alone does not alleviate symptoms. While steroids can temporarily reduce inflammation, they come with potential downsides:
- Possible cartilage damage over time
- Inhibition of the natural healing process
- Short-lived symptom relief
Hyaluronic Acid Injections
Hyaluronic acid is a component of the joint’s natural lubricating fluid. Injection can help with:
- Temporary relief of mild osteoarthritis
- Improved knee lubrication
However, hyaluronic acid injections do not heal the meniscus. They may provide symptom relief for a few months, but they are not curative.
Advanced Regenerative Orthopedic Treatments at Regenexx Pittsburgh
Regenexx is a world leader in regenerative medicine, offering state-of-the-art, in-office interventional orthopedics. If you’re looking for a non-surgical alternative in Pittsburgh, consider:
Platelet-Rich Plasma (PRP)
PRP involves concentrating the growth factors from your own blood platelets and injecting them directly into the injured tissues. With precise ultrasound guidance, PRP can be directed to:
- Torn sections of the meniscus
- Nearby ligaments or tendons
- The knee joint itself
More than 25 high-level studies show that PRP helps with knee pain and can support healing of soft tissue injuries [9]. It’s often recommended for meniscus tears accompanied by mild to moderate arthritis.
Bone Marrow Concentrate (BMC) Containing Stem Cells
For more severe meniscus tears or cases of moderate to severe arthritis, Bone Marrow Concentrate (BMC) containing your own live stem cells can be beneficial. In randomized control trials, BMC has been associated with significant improvement in knee pain and function [10-12].
How It Works: The process involves drawing a small amount of bone marrow (usually from the back of the pelvis), concentrating it to isolate beneficial cells and growth factors, and injecting that concentrate into the affected knee under imaging guidance.

Types of Meniscus tears
In general there are 6 types of meniscus tears. Each can have different symptoms and treatment options.
1. Horizontal Tear (Longitudinal)
This is a tear that runs up and down or left to right through the meniscus. Thes occur mostly in the “red zone” of the meniscus, where there is a good blood supply. Due to this it can potentially heal on its own, but if that does not occur surgical repair could be helpful.
2. Radial Tear (Transverse)
This type of tear is the most common and runs left to right through the meniscus. It often occurs in the “white zone” of the meniscus, the area that does not get much blood supply. This location makes it hard to heal naturally. Physically Therapy should be the first step for these types of tears, but they may benefit more from PRP or bone marrow concentrate. Surgery should rarely be done for this type of tear, as it can make the knee worse.
3. Intrasubstance Tear (Incomplete)
This is a type of degenerative tear in the midportion of the meniscus. These are very common after the age of 30, and often the knee pain will be caused by other knee issues like arthritis. Physical therapy should be the first line of treatment for mild or moderate arthritis, followed by PRP. Bone Marrow Concentrate can be used to treat more severe cases of arthritis.
4. Bucket-handle Tear
In this type of tear the meniscus is torn and flipped over like a bucket handle. It can cause some catching or altered motion of the knee and is one of the rare types of rear that requires surgery. Here a meniscectomy or removal of the meniscus is done as it may be beyond repair. If the knee does not have the symptom of catching or altered motion, then it is possible that physical therapy can help.
5. Flap Tear
A type of tear, where a small section of the meniscus has been torn and flipped over. If this type of tear occurs with catching of the knee as a symptom then surgery may be needed to remove the torn section. As long as there is no catching of the knee then Physical therapy can be attempted, with PRP and Bone Marrow Concentrate as alternatives.
6. Complex Tear
The final type of tear is a complex tear or one that is made up of a combination of several different types of tear. Here, surgeons commonly do meniscectomy as this type of tear is quite difficult to repair.
