Understanding Cartilage Restoration Procedures & Biological Resurfacing
Focal chondral defects—craters in the smooth articular cartilage of the knee, ankle, or hip—typically result from sports injuries, impacts, or osteochondritis dissecans (OCD). Because articular cartilage does not heal spontaneously, these defects create localized stress concentrations that rapidly degenerate into bone-on-bone arthritis if neglected. Cartilage restoration techniques implant cellular scaffolds or living osteochondral cylinders to resurface the defect.
The Biological Joint-Sparing Philosophy
By correcting mechanical weight-bearing malalignment through precision osteotomy and cartilage preservation, the load is shifted off damaged cartilage onto healthy bone—preserving your natural joint for years to come.
When Should You Consider Consultation for Cartilage Restoration?
Specialist intervention is considered when joint pain or functional limitation significantly disrupts your daily life and conservative measures have been exhausted. Check if you experience any of the following:
Localized joint pain and persistent swelling after athletic pivoting.
Mechanical catching, clicking, or sudden locking sensation during knee flexion.
MRI scan revealing a discrete focal cartilage lesion (Grade III / IV defect).
Young or middle-aged active individual seeking biological alternatives to joint replacement.
Activity-related swelling limiting sports or exercise routines.

Treatment Modalities Offered
Dr. Vijay Kumar practices conservative joint-sparing protocols first, proceeding to advanced surgical intervention only when indicated:
Non-Surgical & Joint Sparing
- Unloader knee bracing to eliminate contact pressure
- Platelet-Rich Plasma (PRP) intra-articular injections
- Low-impact cycling and aquatic therapy
- Neuromuscular kinetic chain conditioning
Specialised Surgical Procedures
- Autologous Matrix-Induced Chondrogenesis (AMIC)
- Osteochondral Autograft Transfer (OATS / Mosaicplasty)
- Subchondral Bone Marrow Stimulation with Collagen Membrane
- Removal of Loose Bodies with Chondral Bed Debridement
Recovery Timeline & Mobility Milestones
Weeks 1–4: CPM motion, touch-down weight bearing.
Weeks 6–8: Transition to full weight bearing and stationary cycling.
Months 3–5: Progressive muscular conditioning and swimming.
Months 6–9: High-level agility drills and clearance for running.
