Under the leadership of Dr. Raghu Nagaraj, Arthomed Clinic offers a comprehensive knee preservation program—including advanced cartilage restoration, outpatient stem‑cell therapies, meniscal repair and transplantation, realignment osteotomies and partial knee replacement—designed to relieve pain, recover function and restore active lifestyles for young and athletic patients.
Advanced Cartilage Restoration Procedures
Microfracture & Scaffold Augmentation: Arthomed employs marrow‑stimulation techniques such as microfracture, often augmented with
collagen or hyaluronic scaffolds to enhance fibrocartilage formation and durability in focal
chondral defects.
Mosaicplasty (Osteochondral Autograft Transfer): For lesions 2–5 cm², mosaicplasty transfers autologous cartilage–bone plugs into the defect, yielding superior long‑term outcomes and higher survival rates than microfracture at 15‑year follow‑up.
Autologous Chondrocyte Implantation (ACI/MACI): Our two‑stage ACI/MACI protocols—harvesting, expanding and reimplanting patient‑derived
chondrocytes under a bio‑membrane—produce durable improvements in pain and function, with systematic reviews confirming good long‑term results in knee osteoarthritis.
Particulated Juvenile Allograft Cartilage (PJAC): For larger defects or failed prior repairs, PJAC offers a single‑stage option, demonstrating
promising early clinical outcomes though with a reoperation rate around 15 % at two years.
Outpatient Stem‑Cell & Biologic Injections
Arthomed’s clinic‑based injections of bone‑marrow aspirate concentrate (BMAC), platelet‑rich plasma (PRP) and adipose‑derived MSCs target early osteoarthritic changes and tendon degeneration, showing comparable functional gains and pain relief through 12 months.
Meniscal Preservation & Transplantation
Meniscus Repair with Fibrin Clot & Scaffolds: We utilize inside‑out and all‑inside repair systems augmented with fibrin clots—achieving healing rates up to 90 % in high‑risk tears—and collagen scaffolds for complex patterns, both of which significantly reduce re‑tear and reoperation rates.
Meniscal Allograft Transplantation: For irreparable or previously resected menisci, arthroscopic allograft transplantation yields good functional outcomes at a minimum 15 years, while acknowledging some progression of compartmental arthritis over time.
Realignment Osteotomies
High Tibial Osteotomy (HTO): Patient‑specific, CT‑guided HTO offloads the medial compartment in varus knees, with 20‑year survivorship between 40 %–85 % and strong predictors of success identified in long‑term series.
Distal Femoral Osteotomy (DFO): In lateral or valgus overload, closing‑ or opening‑wedge DFO restores alignment and yields good‑to‑excellent Knee Society Scores in over 75 % of cases at five‑ to ten‑year follow‑up, with no significant differences between techniques.
Partial (Unicompartmental) Knee Replacement
Arthomed offers both conventional and robotic‑assisted unicompartmental knee resurfacing for isolated compartment disease, preserving ligaments and healthy cartilage. Ten‑year implant survival exceeds 89 %, with faster recovery and functional outcomes comparable to total knee
arthroplasty in appropriately selected patients.
