A horizontal meniscus tear is a type of injury to the meniscus where the tear runs parallel to the surface of the meniscus rather than perpendicular to it.
It may originate from a blister that forms within the internal portions of the meniscus and eventually splits through one of the meniscal surfaces dividing your meniscus into a bottom and top half (like an open fish mouth lower and upper jaw).
As a result, horizontal meniscus tears typically cause pain with activity or with deep squats, and may not be all that symptomatic when being inactive. In some cases, they can also cause swelling, catching and/or stiffness in your knee.
You may still be able to walk with a horizontal meniscal tear, and in fact, many athletes continue to play with a horizontal meniscal tear.
Your meniscus is a wedge-shaped piece of cartilage that is critical to the long term health of your knee because it evenly distributes the forces in your knee joint with every step.
If you choose to live with a horizontal meniscus tear or have it partially removed, “cleaned up” or “trimmed,” you are at a significant risk of developing knee arthritis – a chronic knee problem that is often so painful that it requires total knee replacement surgery. Knee replacements can have serious complications and only last about 20 years. Each revision results in loss of bone and increased risk of major complications. Total knee replacement is not a trivial surgery.
Why not just live with it? Because a meniscus that has a horizontal tear results in increased pressures at focal regions of the femoral and tibial knee articular surfaces. This causes progressive degeneration of the articular cartilage, as shown in the study below:
Fig 4A: D. A digital scan shows pressure-sensitive film markings for an (A) intact meniscus, (B) horizontal tear in the posterior third, (C) superior leaf removed, and (D) both leaves removed. The film was super-low range. The anterior of knee is toward the bottom of the image. The decreases in contact area after single- and double-leaf resection are evident.

It takes 6 weeks for musculoskeletal tissues to heal. During this time, the meniscus tear edges must be firmly held together as there are too many knee forces acting on the tear and constantly pulling it apart.
Circumferential Technique is biomechanically stronger than traditional techniques
Dr. Saliman’s NovoStitch medical device allows surgeons to place circumferential sutures around meniscus tears – providing uniform, anatomic compression of the tear edges.
Old techniques, performed mostly by hand and needles, only effectively sew together the top part of the tear. This leads to partial healing and increased risk of meniscus re-tears.

Lack of economic incentives and poor training account for why
most surgeons unfortunately decide to trim, remove or partially mitigate symptoms.
1
Circumferential repair is difficult
Circumferential stitch repair is quite hard to do and requires specialized training. Using the NovoStitch is like rubbing your belly and patting your head, and each stitch requires arthroscopic knot tying, a skill most knee surgeons infrequently perform. Stitches should be placed every 5mm or so, which means to do a good job the surgeon will need to place several stitches and tie several knots. And managing the sutures to get optimal placement in all zones can be very confusing for surgeons who don’t have years of experience with this technique.
2
Meniscus repair does not pay well
Meniscus repair is one of the poorest paying procedures an orthopaedic surgeon can do. As a result surgeons don’t put in the long hours (or years) of practice necessary to become facile at placing circumferential compression stitches for complex meniscus tears. Furthermore, some of the surgery centers will not allow the surgeon to put in enough stitches because the cost of each stitch can in some cases mean the surgery center will lose money on the case.
3
Once bitten twice shy
Older repair techniques are much easier to perform but are less effective at anatomically reducing and uniformly compressing the torn edges during healing. This is especially true of tears that involve the tibial (bottom) side of the meniscus or that are not classic vertical peripheral third tear patterns. Surgeons who use old techniques struggle to place adequate stitches in the middle third (‘red-white’) zone and on the bottom side of the tears, hence they have seen failure of their repairs, leading them to believe the meniscus can’t heal when in reality the failures are typically from inadequate sewing.
4
It’s easier to sell meniscus removal
Patients don’t need rehab and can more quickly return to sports when you remove their meniscus. There’s also no need for bracing. Surgeons explain meniscus removal surgery as ‘quick and easy’, and patients love that, but at what cost?
5
Injections & replacement pay well
When arthritis sets in from not having a functional meniscus (from either leaving it torn or having it removed), the patient usually returns to the same doctor. That doctor profits from giving regular injections to mitigate pain (the only effect of all injection types) and from performing the eventual knee replacement surgery.
6
Risk of injuring nerves & arteries
Traditional repair techniques involve needle penetration beyond the capsule into the back of the knee which has been shown to risk catastrophic injury. Other times it causes significant pain in the back of the knee after surgery. Either way, it’s best to avoid risk of neurovascualr injury. The NovoStitch does not require needle penetration toward the neurovascular structures.
While all doctors should be doing this, the vast majority do not objectively measure and keep track of this data, so they don’t really know what about their treatments does and does not work.
Below are some examples of our team’s great results. Each tile displays a patient’s initial and latest follow-up scores, which are independently measured and authenticated by a software called OutcomeMD.
Flying
Most patients can fly out the same or the next day.
Driving
You will be able to drive if and when you are off all pain medications (except anti-inflammatories), you feel it is safe to do to so, and you feel comfortable hitting the brakes hard if needed.
The surgical team does a plastic surgery closure for the small incisions and there are no stitches to take out. One day after surgery you can remove the brace and ACE bandage and take a shower. There will be a waterproof dressing underneath the ACE bandage that should remain in place until 7 days after surgery, at which time you can remove it and continue to shower normally.
Blood clots are very uncommon after meniscus repair sugery, however to further reduce your risk,, you will have a small sticker on the outside lower part of your knee. This is a neuromuscular electrostimulation technology named Geko. It will stimulate your calf muscle for around 30 hours after surgery. If the stimulation is bothering you there is a minus button which lets you turn it down.
Horizontal, Bucket Handle, Vertical,
Intrasubstance, and Complex Tears
Immediately after surgery you will be able to walk with a hinged knee braced locked in extension (the brace is typically covered by insurance). NO need for crutches.
For the next 6 weeks after surgery, you will be required to wear this knee braced locked in extension during weight-bearing.
During this period of time, you will be able to unlock the knee brace and allow your knee to bend to 90 degrees when not bearing weight.
Note: It is highly important that you do not place weight across a bent knee until your surgeon allows you to do so, as the repair needs enough time to heal before tolerating it.
Redial and Root Tears
In order for the repaired meniscus to properly heal, you will be typically required to NOT bear weight for 6 weeks after surgery. A knee brace is not required for radial or root tear repairs.
Isometric Quad Exercises
To avoid losing muscle strength, perform isometric quad exercises as directed in your post-op instructions provided by your care team
You will have a follow up consultation a week after surgery. At this visit you will be given a physical therapy prescription, rehab protocol and a copy of the operative report. You will also have a follow up visit after you have completed about 6 weeks of physical therapy to make sure you are on course. Our care team will be reachable throughout your healing journey. If you live far away or out-of-state, your visits can be via telephone or HIPAA compliant Zoom.
Due to the brace and/or non-weight bearing status, your quadriceps and hamstrings will become very weak. So no matter the type of tear, 6 weeks after surgery you will need to start physical therapy to regain your motion and strengthen your leg.
Your surgeon will give you a particular protocol for you and your physical therapist to follow after surgery.
This is usually allowed 4-9 months after surgery.
Our team measures and follows all of their patients’ outcomes for several years after surgery using a unique software to objectively report your progress called OutcomeMD.

Removing or trimming meniscus has not been shown to improve symptoms better than non-operative care
The area of the meniscus that ‘doesn’t have a good blood supply, typically the central and middle third of the meniscus, can, in fact, heal. These zones are just harder to repair with traditional techniques. And the central third can be removed as it has not been shown to be critical to the knee’s long-term health. So what’s really important is to have any tears that occur in the middle or peripheral third repaired (assuming the knee is not already arthritic, in which case the options are conservative treatment or knee replacement surgery). Below are papers demonstrating that the avascular zone can, in fact, heal, and these papers were published even before the Circumferential Stitch for meniscus repair enabled improved mechanical repairs.

Knee replacements work well when there are no other options but have potentially devastating complications (infection, DVT, pneumonia, and blood loss leading to heart attack). Also, they don’t last forever. Every 20 years or so, patients must undergo revision surgery and lose bone mass each time. Second and third revision surgeries have dramatically increased risks of complications. Prevention via meniscus repair should be the gold standard of treatment if your knee is not already arthritic.
Patients fly in for surgery frequently. If you are out of state please book a Zoom consult.
Your menisci are two wedge-shaped pieces of cartilage that function to evenly distribute forces in your knee joints and effectively act as shock absorbers every time you take a step. Your menisci are critical to the long-term health of your knee, and any simple wrong position or twist can lead to a meniscus tear. When the function of your meniscus is compromised, your knee is at a high risk of becoming progressively painful and arthritic. The only definitive treatment for an arthritic knee is total knee replacement – so, SAVE YOUR MENISCUS!
Cold therapy is not typically covered by insurance, and is optional. While meniscus repair surgery is not all that painful, cold therapy can help ease postoperative discomfort.
A meniscus tear is a common knee injury frequently caused by everyday activities that put pressure on the knee joint, such as squatting to pick something up or getting in and out of a car. Meniscus tears may cause pain, clicking and/or the sensation of your knee getting stuck or giving out. In some cases they can also cause swelling and/or limited motion. You may still be able to walk after you tear your meniscus, and in fact, many athletes continue to play with a meniscal tear, albeit with pain and decreased function.
Yes, we track all your outcomes using objective, literature-validated assessments of patient-reported outcomes, using software called OutcomeMD. It measures and monitors all outcomes and decides when and on whom to operate based on the long-term results of all other patients who have undergone similar surgeries.
If you’ve been told you need meniscus surgery — or that your tear can’t be repaired — get a second opinion from our team. Many tears previously considered irreparable can be successfully treated with circumferential stitching.
