Meniscus Surgery

Meniscus surgery is performed to treat selected meniscus tears that cause persistent pain, mechanical locking, recurrent swelling, or instability and do not respond adequately to non-surgical treatment. Depending on the tear pattern, tissue quality, age, blood supply, and location of the injury, surgery may involve meniscus repair, partial meniscectomy, or treatment of associated ligament and cartilage problems.

The meniscus plays an important role in load distribution, shock absorption, joint stability, and protection of the articular cartilage. For this reason, preserving as much healthy meniscal tissue as possible is generally preferred when technically appropriate.

What Is the Meniscus?

The menisci are two crescent-shaped fibrocartilage structures located between the femur and tibia inside the knee.

Each knee has a medial meniscus on the inner side and a lateral meniscus on the outer side.

They help distribute body weight across the knee, absorb shock, contribute to stability, and protect the articular cartilage.

What Is Meniscus Surgery?

Meniscus surgery is usually performed arthroscopically through small incisions around the knee.

A camera and specialized instruments are inserted into the joint to evaluate the tear directly and determine whether the damaged meniscus should be repaired, partially removed, or treated with another technique.

Does Every Meniscus Tear Need Surgery?

No.

Many meniscus tears, especially degenerative tears without true mechanical locking, can be treated initially with activity modification, rehabilitation, strengthening, and symptom management.

MRI evidence of a meniscus tear alone is not an automatic indication for surgery.

When Is Meniscus Surgery Considered?

Surgery may be considered when there is:

• Persistent pain despite appropriate rehabilitation
• True mechanical locking of the knee
• An unstable displaced meniscus tear
• A repairable traumatic tear in an active patient
• A bucket-handle tear
• A meniscus root tear in an appropriate patient
• A meniscus tear associated with ACL reconstruction
• Recurrent swelling or catching clearly related to the tear

What Is a Traumatic Meniscus Tear?

A traumatic meniscus tear usually occurs after twisting, pivoting, squatting, or sports injury.

These tears are more common in younger and active patients and may be associated with ACL or other ligament injuries.

Certain traumatic tear patterns have better potential for repair than degenerative tears.

What Is a Degenerative Meniscus Tear?

Degenerative tears develop gradually as meniscal tissue changes with age and repeated loading.

They are common in middle-aged and older adults and may occur together with knee osteoarthritis.

Because many degenerative tears can be asymptomatic, treatment should focus on the patient's symptoms and overall knee condition rather than MRI appearance alone.

What Symptoms Can a Meniscus Tear Cause?

Possible symptoms include:

• Pain along the joint line
• Swelling
• Clicking or catching
• Difficulty squatting
• Pain with twisting
• Loss of full knee movement
• Mechanical locking
• Recurrent swelling after activity

What Is True Knee Locking?

True mechanical locking means the knee physically cannot fully straighten or bend because a displaced structure blocks movement.

A displaced bucket-handle meniscus tear is one possible cause.

Pain-related stiffness should be distinguished from a true mechanical block.

What Is a Bucket-Handle Meniscus Tear?

A bucket-handle tear is a longitudinal tear in which a large portion of the meniscus can displace toward the center of the knee.

It may cause sudden locking, loss of extension, pain, and swelling.

In suitable cases, preservation and repair of the displaced meniscus may be preferred.

What Is a Meniscus Root Tear?

The meniscus roots anchor the meniscus to the tibia.

A root tear can significantly reduce the meniscus's ability to distribute load and may function mechanically similar to loss of a large portion of the meniscus.

Root repair may be considered in selected patients depending on cartilage condition, alignment, age, activity level, and chronicity.

What Is a Radial Meniscus Tear?

A radial tear extends from the inner free edge toward the outer portion of the meniscus.

Larger radial tears can disrupt the circumferential fibers that allow the meniscus to transmit load effectively.

Some radial tears can be repaired using modern arthroscopic techniques.

What Is a Horizontal Meniscus Tear?

A horizontal tear divides the meniscus into upper and lower layers.

These tears are often degenerative but can sometimes be associated with a parameniscal cyst.

Treatment depends on symptoms, tissue quality, tear location, and the overall condition of the knee.

What Is a Flap Tear?

A flap tear creates an unstable piece of meniscal tissue that may move during knee motion.

If the flap causes persistent mechanical symptoms and cannot be repaired, selective removal of the unstable portion may be considered.

How Is a Meniscus Tear Diagnosed?

Diagnosis begins with the history of injury and physical examination.

The examination may assess:

• Joint-line tenderness
• Knee swelling
• Range of motion
• Pain with twisting or deep flexion
• Ligament stability
• Mechanical locking
• Associated patellar or cartilage problems

What Is the McMurray Test?

The McMurray test is a clinical maneuver used to evaluate possible meniscus injury.

Pain or a palpable click during rotational movement of the knee can support the diagnosis, but no single physical test is completely diagnostic.

Are X-Rays Needed?

X-rays do not directly show most meniscus tears.

They are useful for evaluating arthritis, fractures, joint-space narrowing, alignment, and other causes of knee pain.

Why Are Standing Knee X-Rays Important?

Weight-bearing X-rays can reveal joint-space loss or malalignment that may significantly influence treatment.

A meniscus tear in an otherwise healthy knee is different from a degenerative tear in a knee with advanced osteoarthritis.

When Is MRI Used?

MRI is commonly used when a meniscus tear is suspected.

It can evaluate:

• Meniscus tear pattern
• Meniscus root injuries
• ACL and PCL injuries
• Cartilage damage
• Bone bruising
• Osteochondral injuries
• Other soft-tissue abnormalities

Does an MRI Meniscus Tear Always Cause Pain?

No.

Meniscus tears can be seen on MRI in people who have no knee symptoms.

The tear must therefore be correlated with the patient's pain location, mechanical symptoms, examination, age, and overall joint condition.

What Are the Main Types of Meniscus Surgery?

What Is Meniscus Repair?

Meniscus repair is an arthroscopic procedure in which the torn edges are stabilized with sutures or specialized fixation devices.

The goal is to preserve meniscal tissue and allow healing while maintaining the meniscus's protective function.

Why Is Meniscus Preservation Important?

The meniscus helps distribute forces across the knee.

Removing large amounts of meniscal tissue increases contact stress on the articular cartilage and may contribute to degenerative changes over time.

For this reason, modern meniscus surgery generally attempts to preserve repairable tissue.

Which Meniscus Tears Can Be Repaired?

Repairability depends on several factors, including:

• Tear location
• Tear pattern
• Tissue quality
• Age of the injury
• Patient age and biological healing potential
• Associated ACL injury
• Knee alignment
• Cartilage condition

Why Does Blood Supply Matter?

The outer portion of the meniscus has a better blood supply than the inner portion.

Tears closer to the vascular outer region generally have greater healing potential than tears located entirely within the poorly vascularized inner zone.

What Are the Red-Red, Red-White, and White-White Zones?

Can a Meniscus Tear Heal Without Surgery?

Some small peripheral tears can heal or become asymptomatic without surgery.

Healing potential depends on tear location, stability, blood supply, and the condition of the knee.

Degenerative tears may also improve symptomatically with rehabilitation even when the MRI appearance remains unchanged.

What Is Partial Meniscectomy?

Partial meniscectomy is arthroscopic removal of the unstable or irreparable part of a meniscus tear.

The surgeon attempts to leave a stable rim and preserve as much functional meniscus as possible.

Total removal of the meniscus is generally avoided whenever possible.

What Is the Difference Between Meniscus Repair and Meniscectomy?

Is Meniscus Repair Always Better?

Meniscus preservation is preferred when the tear has a reasonable chance of healing and can be stabilized effectively.

However, not every tear is repairable. Severely degenerative, fragmented, or poorly vascularized tissue may not hold sutures or heal reliably.

The appropriate treatment is determined after considering both long-term preservation and biological feasibility.

How Is Meniscus Repair Performed?

Repair techniques can be performed arthroscopically using sutures or specialized fixation devices.

Common approaches include:

• All-inside meniscus repair
• Inside-out meniscus repair
• Outside-in meniscus repair
• Transtibial repair techniques for selected root tears

Technique selection depends on tear location and pattern.

What Is All-Inside Meniscus Repair?

All-inside repair uses arthroscopic devices that allow fixation to be placed from inside the joint without a larger accessory incision.

It is commonly used for selected posterior and middle meniscus tears.

What Is Inside-Out Meniscus Repair?

Inside-out repair passes sutures from inside the knee through the meniscus and out through a small incision.

It provides versatile fixation for many tear patterns but requires careful protection of nearby nerves and vessels.

What Is Outside-In Meniscus Repair?

Outside-in repair passes sutures from outside the knee into the joint and is particularly useful for selected anterior meniscus tears.

How Is a Meniscus Root Tear Repaired?

A root tear may be repaired by reattaching the meniscus close to its normal anatomical attachment.

In transtibial pullout techniques, sutures are passed through a small tunnel in the tibia and secured to restore meniscal function.

Root repair is not suitable for every patient, especially when advanced arthritis or substantial malalignment is present.

Can Meniscus Surgery Be Performed With ACL Reconstruction?

Yes.

Meniscus injuries commonly occur together with ACL tears.

When a tear is repairable, meniscus repair may be performed at the same time as ACL reconstruction.

Does ACL Reconstruction Affect Meniscus Healing?

Meniscus repair performed together with ACL reconstruction can have a favorable biological environment because bleeding and healing factors from the reconstruction may support tissue healing.

Stability provided by ACL reconstruction may also protect the repaired meniscus from repeated abnormal shear forces.

Can Cartilage Injuries Be Treated During Meniscus Surgery?

Yes.

Arthroscopy allows evaluation of the cartilage surfaces, and selected focal cartilage injuries may be treated during the same procedure.

The appropriate cartilage treatment depends on lesion size, depth, location, and joint condition.

Is Arthroscopic Meniscus Surgery Used for Knee Osteoarthritis?

Arthroscopic partial meniscectomy is generally not a routine treatment for primary knee osteoarthritis or an incidental degenerative meniscus tear.

Patients with advanced degenerative changes often have pain from the entire joint rather than from one isolated meniscal fragment.

True mechanical locking or a clearly unstable focal lesion may represent a different clinical situation.

What Happens Before Meniscus Surgery?

Before surgery, the orthopedic evaluation considers symptoms, MRI findings, standing X-rays when appropriate, ligament stability, cartilage condition, and limb alignment.

The patient should understand that the final decision between repair and partial removal may sometimes depend on the appearance and quality of the meniscus during arthroscopy.

How Is Arthroscopic Meniscus Surgery Performed?

Small incisions are created around the knee.

An arthroscope is inserted to examine the joint, and specialized instruments are used to repair or selectively remove damaged tissue.

Other structures such as the ACL, cartilage, and articular surfaces can also be assessed during the procedure.

What Type of Anesthesia Is Used?

Meniscus arthroscopy may be performed under general anesthesia, spinal anesthesia, or another anesthetic technique depending on the patient, procedure, and anesthesiology assessment.

Can Meniscus Surgery Be a Same-Day Procedure?

Many uncomplicated arthroscopic meniscus procedures can be performed without an overnight hospital stay.

Admission requirements vary according to the procedure performed, associated surgery, medical condition, and postoperative needs.

What Are the Risks of Meniscus Surgery?

Possible risks include:

• Infection
• Bleeding
• Deep vein thrombosis
• Joint stiffness
• Persistent pain or swelling
• Failure of a meniscus repair to heal
• Recurrent meniscus tear
• Nerve or vessel injury
• Need for additional surgery

Can a Repaired Meniscus Fail to Heal?

Yes.

Meniscus healing is influenced by tear location, tissue quality, blood supply, patient age, smoking, rehabilitation, instability, and other biological factors.

Some repaired tears can remain symptomatic or tear again and may require further treatment.

Can a Meniscus Tear Again After Surgery?

Yes.

A new injury can damage either the repaired area or another portion of the meniscus.

Returning to pivoting sports before adequate rehabilitation can increase reinjury risk.

What Is Recovery Like After Partial Meniscectomy?

Recovery after partial meniscectomy is generally faster than after meniscus repair because no repaired tissue needs prolonged biological protection.

Walking and exercises are usually advanced according to pain, swelling, quadriceps control, and the surgeon's instructions.

Return to demanding activity should still depend on functional recovery rather than time alone.

What Is Recovery Like After Meniscus Repair?

Meniscus repair requires a more protective rehabilitation program because the sutured tissue must heal.

Weight bearing, knee flexion, squatting, running, and pivoting may be restricted or progressed gradually depending on the location and type of repair.

Are Crutches Needed?

Crutches may be used after both meniscectomy and repair.

They are more commonly required for a longer period after selected meniscus repairs or root repairs where weight bearing must be protected.

Is a Knee Brace Needed After Meniscus Surgery?

A brace is not required after every meniscus procedure.

It may be used after selected repairs to limit motion or protect the repair during the early healing phase.

Why Is Physical Therapy Important?

Rehabilitation helps restore knee motion, reduce swelling, recover quadriceps strength, normalize walking, and gradually prepare the knee for higher loads.

After repair, rehabilitation must also protect the healing meniscus.

When Can the Knee Be Fully Bent?

Flexion progression depends on the procedure performed.

After some repairs, deep flexion is limited temporarily because it can place greater stress on certain regions of the meniscus.

There is no single flexion schedule suitable for every tear.

When Can Squatting Begin?

Deep squatting creates substantial load on the posterior meniscus.

After repair, it is generally introduced only after adequate biological healing, motion, and strength have developed.

The timing depends on tear pattern and repair technique.

When Can Running Begin?

Running should begin only after swelling is controlled, knee motion is restored, strength is sufficient, and the repair has progressed enough to tolerate repetitive loading.

The timeline differs significantly between partial meniscectomy, standard meniscus repair, and root repair.

When Can Sports Be Resumed?

Return to sport should be based on:

• Healing of the meniscus
• Full or appropriate knee motion
• Absence of significant swelling
• Quadriceps and hamstring strength
• Balance and neuromuscular control
• Running and jumping tolerance
• Sport-specific movement ability

Why Should Return to Sport Not Be Based Only on Time?

Different tears heal at different rates, and muscle recovery varies between patients.

A knee that feels better may still lack adequate strength, control, or biological healing for high-demand pivoting activity.

Can Meniscus Removal Cause Arthritis?

Loss of meniscal tissue increases contact pressure within the knee and is associated with a greater risk of degenerative changes over time.

The risk generally increases as more functional meniscal tissue is lost.

This is one of the reasons meniscus preservation is emphasized whenever possible.

What Is Meniscus Deficiency?

Meniscus deficiency occurs when a substantial portion of the meniscus has been removed or no longer functions effectively.

This can lead to increased compartment loading, pain, and cartilage degeneration, especially in younger active patients.

What Is Meniscus Transplantation?

Meniscus transplantation uses donor meniscal tissue to replace a severely deficient meniscus in carefully selected patients.

It is generally considered for younger or middle-aged patients with persistent compartment pain after substantial meniscus loss and without advanced osteoarthritis.

It is not a routine treatment for every patient who has previously undergone meniscectomy.

Can Meniscus Transplantation Prevent Arthritis?

Meniscus transplantation may improve symptoms and restore some load-distribution function in selected patients, but it cannot guarantee prevention of future osteoarthritis.

Why Is Knee Alignment Important Before Meniscus Surgery?

Varus or valgus malalignment can place excessive load on one compartment of the knee.

In selected patients with a meniscus root injury, meniscus deficiency, or cartilage damage, significant malalignment may need to be addressed to protect the repaired or reconstructed tissue.

Can Osteotomy Be Combined With Meniscus Surgery?

Yes.

In selected patients, high tibial osteotomy or distal femoral osteotomy may be performed to redistribute load away from a damaged compartment.

This is considered according to alignment, cartilage condition, age, symptoms, and the type of meniscus injury.

Can Meniscus Surgery Eliminate All Knee Pain?

Not necessarily.

Knee pain may also come from osteoarthritis, cartilage injury, bone abnormalities, ligament instability, patellofemoral disorders, tendons, or other structures.

Surgical treatment is most useful when symptoms correlate well with a treatable meniscal problem.

When Should You See an Orthopedic Specialist?

Evaluation may be appropriate when there is:

• Persistent joint-line pain after a twisting injury
• Recurrent knee swelling
• True locking of the knee
• Persistent catching
• Difficulty fully straightening the knee
• A displaced meniscus tear on MRI
• A suspected meniscus root tear
• A meniscus tear associated with an ACL injury
• Symptoms that continue despite rehabilitation

When Is More Urgent Assessment Needed?

Prompt orthopedic assessment is appropriate when the knee becomes truly locked after an injury, significant swelling develops rapidly, weight bearing is severely limited, or a displaced bucket-handle tear or associated fracture is suspected.

Meniscus Surgery in Antalya

Planning meniscus surgery begins with determining whether the tear is traumatic or degenerative, whether it is stable or displaced, whether it can be repaired, and whether additional problems such as ACL injury, cartilage damage, arthritis, or limb malalignment are present.

When possible, preserving healthy meniscal tissue is preferred. Repair may be considered for suitable longitudinal, bucket-handle, radial, and root tears, while partial meniscectomy may be used when an unstable portion of the meniscus cannot be reliably repaired.

Rehabilitation is planned according to the procedure performed. Meniscus repairs generally require greater protection during healing, while recovery after partial meniscectomy can usually progress more quickly. Return to sport should be based on healing, strength, knee control, and functional testing rather than a fixed universal timetable.

Frequently Asked Questions About Meniscus Surgery

Does every meniscus tear require surgery?

No. Many tears can be managed with rehabilitation, particularly degenerative tears without true locking or significant mechanical symptoms.

What is the difference between meniscus repair and meniscectomy?

Repair preserves and sutures the torn tissue, while partial meniscectomy removes only the unstable portion that cannot be repaired.

Why is meniscus repair preferred when possible?

Preserving meniscal tissue helps maintain load distribution and reduces the amount of stress transferred to the articular cartilage.

Can a bucket-handle tear be repaired?

Many bucket-handle tears can be repaired if the tissue quality, location, tear pattern, and biological conditions are favorable.

What is a meniscus root tear?

It is an injury near the attachment of the meniscus to the tibia that can substantially reduce the meniscus's ability to distribute load.

Can meniscus surgery be performed with ACL reconstruction?

Yes. Repairable meniscus tears are commonly treated during ACL reconstruction when clinically appropriate.

Is meniscus surgery useful for knee arthritis?

Arthroscopic meniscus surgery is generally not a routine treatment for primary osteoarthritis or an incidental degenerative meniscus tear without a clear mechanical indication.

Can a repaired meniscus tear again?

Yes. Healing is not guaranteed, and either the repaired area or another part of the meniscus can be injured again.

When can I return to sports after meniscus surgery?

Return depends on the procedure, meniscus healing, strength, swelling, range of motion, movement control, and sport-specific testing.

Does removing part of the meniscus increase arthritis risk?

Loss of meniscal tissue increases joint contact pressure and is associated with a higher risk of degenerative changes, particularly when larger amounts of tissue are removed.
