Sarvodaya Hospital, Faridabad, brings North India’s First Hip Navigation Technology for Hip Replacement Surgeries
New Delhi [India], June 26: In a significant advancement in orthopaedic care, Sarvodaya Hospital has introduced North India’s first advanced hip navigation technology for hip replacement surgeries, aimed at improving surgical precision and long-term patient outcomes. The technology uses computer-assisted, real-time data to guide surgeons before and during the hip replacement surgery, enabling more accurate implant placement & leg length equalisation while significantly reducing complications like hip dislocation.
Hip replacement surgery involves replacing a damaged joint with an artificial implant. A critical part of the procedure is positioning the implant correctly, particularly the acetabular cup placement (which fits into the hip socket) & leg length equalisation during the surgery. According to doctors, even minor variations in cup angle or leg length can affect mobility and long-term success of the implant. The newly introduced navigation system addresses these challenges by providing precise measurements during surgery, something that is difficult to achieve consistently with conventional techniques that rely largely on manual assessment. Sarvodaya Hospital has already successfully performed hip replacement surgeries using this technology. Unlike traditional methods, where surgeons visually assess leg length and alignment, the navigation system provides intraoperative feedback to enhance accuracy. It also assists in pre-surgical planning through specialised software, enabling doctors to determine the appropriate implant size, shape, position, and alignment based on the patient’s unique anatomy, thereby improving implant performance.
While minimally invasive surgical techniques like the Direct Anterior Approach (DAA) ensure very little pain after surgery, hip navigation technology adds the promise of a good long-term outcome. Commenting on the development, Dr. Pankaj Walecha, Director & Head – Robotic Knee & Minimally Invasive Hip Replacement at Sarvodaya Hospital, said, “Hip replacement is a highly technique-sensitive procedure where implant positioning, leg length equalisation & restoration of normal hip anatomy play a crucial role in outcomes.
He added, “Every patient’s hip anatomy is different, and reconstructing the new hip like the normal natural hip of the patient is key to restoring normal function. Navigation helps to select implants that are better suited to the individual patient’s anatomy and also helps the surgeon to align them more accurately during surgery. This improves joint stability, enhances mobility, and in many cases, helps patients regain a feeling of a near-natural joint over time.” This technology also complements minimally invasive surgical approaches such as the direct anterior approach (DAA), where the patient lies supine (on their back) during surgery. While DAA already offers quicker recovery, the addition of navigation further improves the results even further.
In addition to minimally invasive hip replacement techniques, the hospital also has an established robotic knee replacement programme supported by a fully active robot for joint replacement surgery. Sarvodaya offers comprehensive knee care for patients at all stages of knee damage, with treatment options ranging from knee preservation to partial knee replacement, unicompartmental knee replacement (UKR), and total knee replacement, depending on the patient’s condition. In advanced knee arthritis, deformity, or severe joint damage, robotic assistance helps doctors plan and perform knee replacement procedures with greater accuracy, particularly in bone preparation, implant positioning, alignment, and joint balancing.
Combining advancements in hip and knee replacement, Sarvodaya Hospital brings together surgical expertise & experience, advanced techniques, and cutting-edge technology to deliver more precise and patient-centric joint replacement care

Tamil Nadu Could Build ₹37,000-Crore Defence Electronics Hub
New Delhi [India], June 30: Defence manufacturing is slowly moving away from traditional hardware-heavy platforms, as modern warfare relies more on software, sensors and secure communication systems. The transition to electronics-based systems is underway, with functions such as electronic warfare, artificial intelligence, and network-centric operations increasingly vital to military capabilities across countries.
According to a roadmap presented by Distinguished Scientist at DRDO and Director General (Electronics and Communication Systems) BK Das, Tamil Nadu can become a major defence electronics hub by 2040 with an annual production capacity of ₹37,000 crore.
Das said the state has a realistic opportunity to capture a significant share of India’s growing defence electronics market, owing to its existing strengths in electronics, semiconductors, aerospace and automotive manufacturing, while speaking at the CII TNDefX Conclave 2026 in Chennai.
The opportunity itself is substantial. India’s defence electronics market is expected to grow to approximately ₹1.49 lakh crore by 2040, and Tamil Nadu is projected to account for 20–25% of this market, according to the roadmap. This also translates into a potential export opportunity of up to ₹10,000 crore per year.
This projection is closely connected with the broader shift in defence systems. Today, from fighter aircraft to naval systems and ground-based surveillance, AI-powered systems, electronic warfare, autonomous platforms, secure communication networks, and space-based technologies are becoming increasingly critical. Electronics, in many respects, is now the backbone of military capability rather than a supporting component.
The case of Tamil Nadu is largely based on its existing industrial ecosystem. The state has built a strong manufacturing base in automotive components, electronics manufacturing, precision engineering and aerospace-related supply sectors over the last decade. Its industrial depth, skilled engineering talent and export-oriented clusters provide an advantage in scaling complex defence manufacturing.
Meanwhile, the policy push on defence self-reliance (Atmanirbhar Bharat) has encouraged private sector participation in areas earlier dominated by the public sector. This transition is gradually opening opportunities for states with strong manufacturing ecosystems to integrate into high-value defence supply chains.
Das believes the development path for defence electronics is not only about production capacity but also about integration into global supply chains. There is a growing trend among countries to diversify sourcing of critical defence components, particularly in electronics and communication systems, where reliability and security are paramount.
The opportunity for Tamil Nadu sits at the intersection of these global and domestic changes. On one side is rising defence spending and technology adoption, while on the other is India’s push for localisation of high-value manufacturing. Together, these forces are reshaping defence ecosystems.
Industry experts at the conclave noted that achieving this scale will require sustained investment in R&D, component ecosystems, testing facilities and skilled manpower development. Defence electronics is not assembly-driven alone; it depends heavily on deep technology capabilities and long development cycles.
The roadmap also suggests stronger collaboration among government institutions, private manufacturers and research organisations such as DRDO. Building capabilities in areas like secure chipsets, radar systems and electronic warfare platforms will require coordinated, long-term development rather than isolated projects.
The projection for 2040 is long-term, but early signs are already visible. Tamil Nadu has been steadily attracting investments in electronics manufacturing, while defence corridors in the state are gradually evolving into structured ecosystems.
If the projections materialise, Tamil Nadu may not only emerge as a manufacturing hub supporting defence production but also as a key centre for defence electronics manufacturing and exports in India. The next decade will likely determine how quickly this transition moves from potential to execution.
