There is a critical window in the life of a damaged knee — a period between “the cartilage is injured” and “the cartilage is gone.” In this window, surgical intervention can repair, restore, and protect the joint surface — potentially delaying or eliminating the need for knee replacement altogether.
Cartilage surgery in Ahmedabad at Dr. Tirth Vyas’s clinic in Gota is about exactly this: giving patients the best possible chance of preserving their natural knee long-term, by treating cartilage damage and associated ligament injuries — particularly PCL tears — at the right time, with the right technique.
As an arthroscopic specialist with fellowship training in Germany and Japan and over 10,000 surgeries, Dr. Vyas has the technical depth to manage the full spectrum of cartilage and ligament conditions — from minor chondral defects to complex combined injury reconstruction.
Why Knee Cartilage Matters More Than Most Patients Realise
Articular cartilage is the smooth, white tissue covering the ends of bones where they meet at the knee joint. Unlike most tissues in the body, it has virtually no blood supply — which means it has extremely limited natural healing capacity. A cartilage injury, once present, does not spontaneously repair the way a muscle strain or skin wound does.
Why this matters clinically:
- An untreated cartilage defect (a “pothole” in the joint surface) causes surrounding cartilage to experience abnormal load — initiating a cascade of progressive damage
- Full-thickness cartilage loss (bone-on-bone) is the end-stage — the point at which knee replacement becomes the primary remaining option
- Cartilage surgery is most effective when performed early — before the defect expands and secondary changes occur in the surrounding bone
How cartilage damage happens:
- Acute trauma — a fall, sports collision, or twisting injury that shears cartilage from the underlying bone (osteochondral fracture)
- Ligament instability — chronic ACL or PCL insufficiency allows abnormal joint movement that gradually erodes cartilage
- Meniscal loss — the meniscus is the knee’s load distributor; when it is removed or torn, cartilage experiences concentrated stress
- Osteochondritis dissecans (OCD) — a condition where a segment of bone and cartilage loses blood supply and becomes separated; predominantly affects young athletes
- Degenerative changes — early-to-moderate osteoarthritis where focal defects appear before generalised cartilage loss
Diagnosing Cartilage Damage in Ahmedabad
MRI is the primary imaging investigation — specifically, high-resolution sequences (T2-fat saturation, DESS) that visualise cartilage thickness, signal intensity, and focal defects. Standard MRI adequately shows moderate-to-severe defects; subtle early damage may require MRI arthrogram (with intra-articular contrast).
Key findings on MRI that indicate cartilage surgery:
- Full-thickness cartilage loss in a focal area (defined defect with clear edges)
- Subchondral bone oedema (bone marrow signal change indicating stress beneath the defect)
- Osteochondral fragment — separated bone and cartilage piece within the joint
- Loss of meniscal tissue amplifying cartilage stress
Arthroscopic assessment — during surgery, Dr. Vyas performs a systematic examination of the entire joint surface, grading cartilage damage using the International Cartilage Repair Society (ICRS) scale. This intraoperative assessment confirms the MRI findings and allows immediate treatment.
Cartilage Surgery Options in Ahmedabad: Choosing the Right Technique
Not every cartilage defect is treated the same way. The optimal procedure depends on the defect size, location, depth, the patient’s age and activity level, and bone involvement.
Chondroplasty (Debridement)
The simplest cartilage procedure — smooth and debride unstable or fibrillated cartilage edges arthroscopically. Does not regenerate cartilage; reduces mechanical irritation from loose flaps.
- Appropriate for: Small, Grade 2–3 defects with stable edges; not appropriate as the sole treatment for full-thickness defects
Microfracture
Small awls create multiple perforations in the subchondral bone beneath the cartilage defect — allowing bone marrow elements (including mesenchymal stem cells) to fill the defect with fibrocartilage.
- Best outcomes for: Defects under 2–2.5 cm², younger patients, subchondral bone intact
- Limitation: Fibrocartilage (type I collagen) is mechanically inferior to native hyaline cartilage (type II collagen) — results may deteriorate in high-demand patients over time
OATS / Mosaicplasty (Osteochondral Autograft Transfer)
Cylindrical osteochondral plugs (bone + cartilage) are harvested from a non-load-bearing area of the patient’s knee and press-fitted into the defect. Results in true hyaline cartilage restoration.
- Best for: Medium defects (1–4 cm²), younger active patients, good donor site available
- Advantage: True hyaline cartilage with subchondral bone support; immediate structural restoration
ACI — Autologous Chondrocyte Implantation
A two-stage procedure:
- Stage 1: Arthroscopic biopsy of healthy cartilage cells; cells cultured in laboratory for 4–6 weeks
- Stage 2: Implantation of expanded cells into the defect covered by a periosteal or collagen membrane
- Best for: Large defects (>4 cm²), younger patients, failed prior microfracture
- Limitation: Two-stage procedure; higher cost; requires longer rehabilitation

PCL Reconstruction in Ahmedabad: The Underdiagnosed Ligament Injury
The posterior cruciate ligament (PCL) prevents the tibia from sliding backward relative to the femur. It is stronger than the ACL but not immune to injury — and PCL tears are significantly underdiagnosed because their initial symptoms can be subtle.
How PCL Tears Happen
- Dashboard injury — in road accidents, the knee is forced against the dashboard with the knee bent, driving the tibia backward
- Fall on a bent knee — landing directly on the front of the tibia with the knee flexed
- Hyperflexion — extreme knee bending forces
Why PCL Injuries Are Different from ACL Injuries
- Pain and swelling may be milder initially, leading patients to dismiss the injury as a “minor sprain”
- Instability is less dramatic — patients describe a “sloppy” feel or discomfort with stairs and inclines rather than sudden giving way
- Chronic PCL insufficiency causes posterior compartment cartilage damage over time — making delayed treatment more complex
PCL Reconstruction Technique
PCL reconstruction follows similar arthroscopic principles to ACL reconstruction but with critical technical differences:
- Posterior tibial tunnel positioning is more complex — the “killer turn” at the PCL tibial insertion requires specific surgical technique to prevent graft abrasion and failure
- Graft choices are similar (hamstring, quadriceps, Achilles allograft) but graft strength requirements are higher as the PCL has greater ultimate load demands
- Double-bundle PCL reconstruction may be required for complete tears — reconstructing both the anterolateral and posteromedial bundles
PCL reconstruction surgery cost in Ahmedabad: ₹75,000 – ₹1,80,000 (see full cost guide: Knee Ligament Surgery Cost in Ahmedabad)

Connecting the Dots: The Knee Preservation Philosophy
At Dr. Tirth Vyas’s clinic, cartilage surgery and PCL reconstruction are part of a broader knee preservation philosophy — the clinical conviction that every possible effort should be made to maintain the natural knee before recommending replacement.
This means:
- Treating cartilage defects when they are focal and repairable — not waiting until they become generalised
- Reconstructing ligament instability (ACL, PCL) that is silently destroying cartilage with every step
- Combining procedures intelligently — addressing the ligament, cartilage, and meniscal issues in one operative session when technically possible

Conclusion: Cartilage Surgery in Ahmedabad — Act Before the Window Closes
Cartilage injuries are not static. They progress — silently, steadily, and often irreversibly if the right intervention isn’t made at the right time. Cartilage surgery in Ahmedabad at Dr. Tirth Vyas’s clinic is about acting within that preservation window — when the joint can still be saved, restored, and protected for decades of active life ahead.
Whether you have a focal cartilage defect from a sports injury, a PCL tear from a road accident, or early degenerative changes that you’re hoping to slow down — Dr. Vyas has the arthroscopic expertise, the international training, and the technical range to give your knee the best possible long-term outcome.
