Arthroscopic partial meniscectomy trims the torn portion of a meniscus that cannot be repaired, preserving as much native tissue as possible. The procedure provides reliable symptom relief for tears that are not amenable to repair and allows quick return to activity. Dr. Chudik’s approach is conservative: removing only what is necessary to resolve mechanical symptoms while preserving meniscus tissue for long-term cartilage protection.
What Is Arthroscopic Partial Meniscectomy?
Some meniscus tears cannot be repaired because of tear location, pattern, or tissue quality. Tears in the avascular inner two-thirds of the meniscus (the white zone) lack the blood supply needed for healing. Severely degenerated tears, complex multi-direction tears, and chronic tears with tissue breakdown also typically cannot be repaired.
For these tears, arthroscopic partial meniscectomy removes the unstable torn fragment while preserving the surrounding stable meniscus. The goal is to eliminate the mechanical symptoms (catching, locking, pain with motion) while leaving as much functional meniscus as possible to continue load distribution.
Modern partial meniscectomy is conservative compared to the total meniscectomies of decades past, which have been associated with accelerated arthritis. Removing only the unstable portion preserves long-term knee mechanics.
Who Is a Candidate?
Candidates for partial meniscectomy typically have:
- A meniscus tear that cannot be repaired (avascular zone, complex pattern, degenerative tissue)
- Mechanical symptoms (catching, locking, painful clicking) interfering with activity
- Failure of non-surgical management for symptomatic tears
- Older patients with degenerative tears that have not responded to conservative care
Patients with repairable tears are offered repair instead. Patients with primarily arthritic symptoms (rather than mechanical symptoms from the tear) may not benefit significantly from arthroscopic surgery and are evaluated for arthritis-directed treatment.
How the Procedure Is Performed
The procedure is performed arthroscopically through standard portals. The torn meniscus is identified and probed to confirm the tear pattern and tissue quality. Repairability is assessed; if the tear is suitable for repair, that is performed instead.
For partial meniscectomy, the unstable torn fragment is precisely trimmed using arthroscopic scissors and shavers. The surgical principle is to leave as much stable meniscus as possible while removing the portions that produce mechanical symptoms. The remaining meniscus rim is contoured to a smooth, balanced edge.
Associated cartilage damage and other intra-articular pathology are addressed at the same procedure when present.
Recovery and Rehabilitation
Recovery is among the fastest in arthroscopic surgery:
- Weight-bearing as tolerated immediately
- Range of motion exercises beginning the day of surgery
- Crutches optional, used for one to two weeks for comfort
- Return to most daily activities within one to two weeks
- Return to sport at four to six weeks
Risks and Outcomes
Risks include persistent symptoms (in cases where the tear was not the primary pain source), stiffness, infection, and accelerated cartilage wear over the long term proportional to the amount of meniscus removed. Outcomes are reliable for symptomatic mechanical tears that cannot be repaired, with most patients returning to activity quickly.
Long-term, the knee with partial meniscectomy is at higher risk of arthritis than the same knee with intact meniscus, which is why preservation is prioritized when feasible.
Why Dr. Chudik for Arthroscopic Partial Meniscectomy
Dr. Chudik’s surgical philosophy prioritizes meniscus preservation. Partial meniscectomy is performed only when repair is not feasible, and the trim is conservative: removing only what is necessary to resolve mechanical symptoms while preserving the maximum meniscus rim. For younger patients who lose significant meniscus, Dr. Chudik can offer meniscus transplantation as a future option to restore the missing tissue.
