Meniscus Injuries: Surgery vs. Physical Therapy
7-minute read
Understanding the Meniscus
The meniscus is a C-shaped cartilage pad in your knee—one medial (inside), one lateral (outside)—that helps absorb shock, distribute load, and stabilize the joint. Despite handling a lot of stress, it has a limited blood supply, which can make healing slow and unpredictable.
How Do Meniscus Injuries Happen?
Meniscus tears may occur during a sudden twist or pivot (common in sports or trail running) or develop gradually due to wear and tear in your 40s–60s.
Big twist injuries often involve younger, athletic individuals.
Slow-onset tears tend to affect older adults experiencing gradual swelling or clicking during everyday activity.
Why Meniscus Tears Resist Healing
Only the outer 10–25% of the meniscus has a good blood supply ("red zone"). Inner tears ("white zone") heal poorly and often require surgical repair or trimming, but they can still become symptom-free with targeted rehab.
The Types of Tearing
The shape of the tear greatly influences how it behaves and heals:
Longitudinal/Bucket-handle tears run along the meniscus. They can flip into the knee and cause locking, but repairable in younger individuals.
Radial tears cut across the structure and often require surgical trimming due to disrupted load distribution.
Horizontal tears (common in older adults) split the meniscus top to bottom and usually represent degeneration.
Flap tears create a loose flap that may catch or lock the joint, often causing discomfort rather than pain.
Complex tears combine different patterns and tend to be harder to treat.
Understanding your tear type helps guide the right treatment—whether that’s rehab or surgical consultation.
Various Images of Meniscus Tears
Surgery or Rehab?
Not every meniscus tear needs surgery, but some do. At Atomic PT, we start with a thorough movement assessment to determine how your tear is affecting your function. If your knee is locking, giving way, or not improving after several weeks of rehab, a surgical referral might be the next step.
When Surgery Makes Sense:
Mechanical symptoms like locking or catching
Persistent swelling or sharp pain with loading
Failed conservative care after 6–8 weeks
Athletes needing a reliable and fast return to sport
Surgical Options Explained
Meniscectomy:
This involves trimming the torn portion of the meniscus—typically used for tears in the inner “white zone” where healing is unlikely. Recovery is faster (about 4–6 weeks), but removing part of the meniscus can slightly increase the risk of early joint degeneration if proper rehab isn’t done.
Meniscus Repair:
Involves suturing the tear, usually for those in the outer “red zone” with good blood flow. This procedure preserves the meniscus and reduces long-term wear, but recovery is longer—often 3–6 months. You'll need bracing, protected weight-bearing, and dedicated rehab.
Root Repair or Complex Reconstruction:
For tears near the meniscal root or involving major instability, these procedures require longer immobilization and progressive rehab to restore full function. They’re more common in older adults or athletes with advanced damage.
How Physical Therapy Helps (Before and After Surgery)
Whether you’re avoiding surgery or recovering from one, physical therapy is one of the most powerful tools available for meniscus rehab. At Atomic PT, we approach every meniscus injury with movement analysis, sport-specific rehab, and strength progressions that return you to the activities you love — not just walking pain-free.
Before Surgery (Prehab)
Goal: Reduce swelling, normalize gait, maintain joint mobility, and build muscle to protect the knee post-op.
Why it matters: Pre-surgical strength and mobility are directly correlated with improved post-op outcomes and faster return to sport.
After Surgery or For Conservative Management
Our approach focuses on restoring movement and building tissue tolerance, not just avoiding pain. Even if you don't opt for surgery, the right exercises can stimulate tissue healing, restore neuromuscular control, and protect the joint long-term.
Evidence Matters:
A 2016 study in BMJ compared physical therapy to arthroscopic surgery for degenerative meniscus tears and found no significant long-term difference in pain or function meaning PT can be just as effective, without the risks of surgery.
Rehab programs that include strength, neuromuscular control, and movement variability result in significantly better outcomes than passive modalities alone (van der Wal et al., Knee Surg Sports Traumatol Arthrosc, 2016).
