Ask anyone who has torn their anterior cruciate ligament and they describe the same three seconds: the plant, the twist, the pop. The swelling arrives within hours. The fear arrives later — on the first stair descended without thinking, when the knee lurches and the ground briefly stops being trustworthy. That sensation of giving way is the signature of ACL injury, and it is the reason the injury cannot simply be waited out.
Dr. Pradyumna Chakraverty diagnoses and treats ACL injuries at his Behala and South Kolkata clinics, performing arthroscopic reconstruction where it is warranted. His MS in Orthopaedics is from KPC Medical College, Jadavpur, and his arthroscopy practice sits alongside trauma and joint surgery — so the whole injured knee is assessed, not the ligament alone.
An experienced examiner can detect ACL insufficiency in the clinic — the ligament's laxity has specific, testable signatures. MRI then confirms the tear and, just as importantly, surveys the structures that tear alongside it: the menisci, the cartilage, other ligaments. Nearly half the decisions in ACL care hinge on those companions. This is why Dr. Chakraverty examines before he images, and reads the MRI himself with your examination findings in mind rather than treating the radiology report as a verdict.
The ACL does not heal itself, but not every torn ACL needs replacing. The honest question is what you ask of your knee:
What is not negotiable is treating instability. A knee that keeps giving way chews through its menisci and cartilage one episode at a time, and buys arthritis early.
Reconstruction is done arthroscopically: a graft of your own tendon is fixed in tunnels drilled at the ligament's original anchor points. The surgery takes an hour or two; the result is decided over the months that follow, as the graft matures and the leg is rebuilt stage by stage — range of movement first, then strength, then control, then sport-specific work. Return to competitive pivoting sport is measured in strength and stability milestones, commonly reached around nine months. Dr. Chakraverty is direct about this timeline before surgery, because the patients who re-tear grafts are overwhelmingly the ones who rushed it.
A twisting injury with a pop, swelling within hours, and a knee that later feels untrustworthy on turns. Confirmed by stability examination and MRI.
No. Low-demand knees can do well with structured rehabilitation. Reconstruction is for pivoting sport, physical work, repeated giving-way, or associated meniscus injury.
The torn ligament is replaced arthroscopically with a graft of your own tendon, fixed in bone tunnels, then matured through staged physiotherapy.
Competitive pivoting sport commonly waits around nine months, earned by strength and stability milestones. Returning early is the most avoidable cause of re-tear.
Repeated giving-way damages the menisci and cartilage, raising the risk of early arthritis. Ignoring instability is the costly option.
