knee arthroscopy

The Knee's Shock Absorber, and Why It Is Worth Saving

Between the thigh bone and the shin bone sit two crescents of cartilage — the menisci — that spread every step's load across the joint. Tear one, and the knee tells you in a particular dialect: pain exactly along the joint line, a click on twisting, a catch on standing from a squat. Tear one badly enough and a flipped fragment can jam the hinge outright, leaving the knee locked short of straight.

Dr. Pradyumna Chakraverty treats meniscus injuries at his Behala and South Kolkata clinics — arthroscopically when surgery is needed, and with disciplined restraint when it is not. His MS in Orthopaedics is from KPC Medical College, Jadavpur; he serves as an Assistant Professor of Orthopaedics.

Two Very Different Tears Share One Name

The traumatic tear belongs to younger knees: a twist under load at football, a slip on a wet Kolkata pavement, sometimes accompanying an ACL rupture. The tissue is healthy and simply torn, which makes it a candidate for repair.

The degenerative tear belongs to knees past forty-five, where the meniscus frays as part of the same process that wears the cartilage — early osteoarthritis. MRI reports these tears in alarming language, but here is the uncomfortable truth Dr. Chakraverty will tell you plainly: trimming a degenerative tear in an arthritic knee frequently fails to help, because the tear was never the whole problem. These knees mostly belong in a strengthening programme, not an operating theatre.

Repair, Trim, or Leave Alone

  • Repair — stitching the tear so it heals. Preferred wherever the tear sits in the blood-supplied outer rim and the tissue holds stitches, because a preserved meniscus is decades of protected cartilage
  • Partial meniscectomy — trimming only the torn, unrepairable fragment. The word "partial" is doing important work: the goal is to remove as little as possible
  • Leave alone — stable, quiet tears and most degenerative tears, managed with quadriceps strengthening and load sense
  • Urgent surgery — the locked knee, where a displaced fragment blocks movement and waiting damages cartilage

The repair-versus-trim decision is made finally inside the joint, where the tissue can be seen and tested — which is why you will hear both possibilities discussed honestly before surgery rather than a single promised procedure.

After the Operation

The two operations have opposite recoveries, and knowing which you had matters. After a trim, the knee is walked on within days and rehabilitation is brief. After a repair, the stitched tissue is protected while it heals — bracing and limited weight-bearing for some weeks, with squatting and pivoting held back for longer. The slower road exists for a reason: it is the price of keeping your shock absorber, and it is nearly always worth paying.

Frequently Asked Questions

What does a meniscus tear feel like?

Joint-line pain worse on squatting or twisting, clicking or catching — and sometimes a knee locked short of straight, which needs prompt attention.

Can a meniscus tear heal on its own?

Outer-rim tears with blood supply can, especially in the young. Inner tears do not — though degenerative tears often become quiet with physiotherapy.

Why prefer repair over removal?

Removing meniscus concentrates load on the cartilage and is strongly linked with earlier arthritis. Repair preserves the cushion.

Do degenerative tears need surgery?

Usually not — strengthening and load management serve these knees better, with surgery reserved for true locking.

What is recovery like?

Days of recovery after a trim; several protected weeks after a repair — because the repaired tissue is being given its chance to survive long-term.
