An orthopaedic surgeon discusses how this approach helps alleviate pain caused by joint injuries and chronic conditions.  

Knee pain is a common condition that can affect mobility and overall well-being, often stemming from sports injuries or chronic conditions like osteoarthritis that develop over time. Depending on the patient’s profile and the severity of the knee condition, treatment approaches range from lifestyle changes and low-level interventions – including weight management, physiotherapy and mild painkillers – to more advanced procedures.

“For moderate cases, treatments such as platelet-rich plasma or hyaluronic acid injections can help reduce pain and promote healing,” said Dr Hamid Razak, a consultant orthopaedic surgeon at Total Orthopaedic Care & Surgery.

In other instances, patients may require surgical procedures such as cartilage repair, meniscus repair or realignment of the knee joint, known as an osteotomy. Total knee replacement, said Dr Hamid, is reserved for cases when other treatments are no longer effective.

CARTILAGE REPAIR, EXPLAINED

Among surgical options, cartilage repair is recognised for its role in restoring the knee’s natural function. Specialists like Dr Hamid tailor this treatment based on factors such as size, location and condition of the cartilage defect.

“Cartilage repair focuses on addressing the damaged surface of the knee joint, improving its natural cushioning and smoothness,” he said. “It’s similar to patching a worn-out tyre to ensure a smooth ride. Early intervention not only prevents further deterioration but also relieves pain caused by exposed bone rubbing against bone.”

There are various techniques for cartilage repair. These range from hyaluronic acid-based scaffolds that support cartilage regeneration to allograft osteochondral plugs, where healthy donor cartilage and bone are used to repair damaged areas. In some cases, these approaches are enhanced with ortho-biologic products (substances that promote tissue healing), such as bone marrow aspirate concentrate and mesenchymal stem cells.

IS CARTILAGE REPAIR SUITABLE FOR YOU

Cartilage repair is generally most effective for younger, active patients with well-aligned, stable knees and healthy meniscus tissue. However, as more older adults adopt active lifestyles, age is becoming less of a limitation for the procedure.

“I recently treated a 60-year-old badminton enthusiast who chose cartilage repair over total knee replacement,” shared Dr Hamid. “With proper alignment and stable ligaments, he was able to return to his favourite sport with ease.”

This technique can also benefit athletes aiming to resume their routines. Dr Hamid recalls treating an athlete in his mid-20s who returned to his sport nine months after undergoing cartilage repair using a hyaluronic acid-based scaffold combined with mesenchymal stem cells, which play a pivotal role in cartilage regeneration.

“The stem cells act as a repair crew,” said Dr Hamid. “The scaffold serves as their ‘home base’, anchoring them at the damaged site, where they transform into cartilage-producing cells to restore hyaline-like cartilage that mimics the joint’s natural cartilage in appearance and function.”

AN OVERVIEW OF HYALURONIC ACID-BASED SCAFFOLDS

Unlike metal implants or total knee replacements, hyaluronic acid-based scaffolds support new cartilage growth while preserving the knee’s natural structure. They may also reduce the risk of biofilm-related infections – hard-to-treat bacterial infections that form a resistant layer – one of the leading causes for implant failure.

Dr Hamid uses autologous minced cartilage together with hyaluronic acid-based scaffolds to improve both the quality and durability of the procedure. “This augments cartilage repair by utilising the patient’s healthy cartilage surrounding the defect as a source of viable cartilage cells,” he said.

According to Dr Hamid, hyaluronic acid-based scaffolds have been widely used by orthopaedic surgeons globally for over a decade. Free of animal by-products, they are suitable for most patients, including Muslims, vegetarians and vegans.

He explained that cartilage repair using hyaluronic acid is typically performed through minimally invasive procedures like arthroscopy (keyhole surgery), which minimises tissue damage, supports faster recovery and enables patients to return home within a day or two.

“Most patients can resume light activities within weeks,” Dr Hamid said, adding that physiotherapy – crucial for optimal healing – can begin almost immediately. While high-impact activities like running or jumping should be avoided for at least three to six months post-surgery, a personalised rehabilitation plan developed with a physiotherapist aids recovery during this period.

Dr Hamid also highlighted that cartilage repair using hyaluronic acid could lower the chances of requiring complex revision surgeries.

“Younger patients undergoing total knee replacements face a high risk of revision, as noted in a study in The Lancet,” he said. “Biocompatible scaffolds provide an alternative by addressing cartilage damage early, which could delay or eliminate the need for total knee replacement.”

Dr Hamid advises patients to consult an orthopaedic specialist to determine if hyaluronic acid-based scaffolds are a suitable option: “This treatment can be effective in many cases, though it is important to consider each case individually. Early intervention is key to managing knee issues and optimising results.”

Wellchem Pharmaceuticals, a distinguished name in Singapore’s pharmaceutical landscape, has carved a niche for itself over the past 50 years. Established in 1975 by Mr. Winthrop Wong’s parents, the company began with the import and export of pharmaceutical products. Today, it has grown to supply pharmaceutical products and medical devices through various channels such as hospitals, tenders, GPs, specialists, retail pharmacies, online platforms and e-commerce sites.

Today, dynamic duo Ms Geraldine Lim and Mr Winthrop Wong lead Wellchem at its helm, consistently pushing the boundaries of healthcare to provide accessible, high-quality medication to its clients. Wellchem stands as a testament to visionary leadership, innovation, and an unwavering commitment to healthcare. Founded on the principles of integrity, quality, and innovation, Wellchem Pharmaceuticals began as a small wholesaler supplying essential medications across Singapore. The directors, Ms Geraldine and Mr Winthrop, were driven by a passion for improving public health and a deep understanding of the pharmaceutical industry. Their journey has been marked by a steadfast commitment to making healthcare accessible and affordable for all.

Over the years, Wellchem Pharmaceuticals has evolved, expanding its reach and diversifying its portfolio. The company now operates two main arms: Wellchem, the wholesale and distribution arm, and Glovida, its retail counterpart. While Wellchem focuses on the wholesale distribution of a wide range of pharmaceutical products to hospitals, clinics, and pharmacies across the region, Glovida offers an extensive array of over-the-counter (OTC) medications and health supplements to the public.

In 2023, the company launched Glovida-RX, an innovative online pharmacy licensed by the Health Sciences Authority (HSA) of Singapore. Having worked as a pharmacist in Australia for a few years, Winthrop experienced the integral roles of pharmacists in the healthcare sector firsthand. However, he believes that their skills are underutilised in Singapore, where pharmacists are an ideal first line of response for healthcare needs. Glovida-Rx was thus conceptualised to raise the profiles of these healthcare professionals. As the healthcare industry increasingly shifts towards digital platforms, Wellchem has positioned itself at the forefront of this transformation.

Glovida-RX, the online extension of Wellchem’s retail operations, provides a seamless experience for customers seeking prescriptions and health advice from the comfort of their homes. This move was a strategic response to the growing demand for digital healthcare solutions and has enabled Wellchem to reach a broader audience. Through Glovida-Rx, Winthrop and Geraldine seek to provide convenient access to essential medications and empower customers to make informed healthcare choices by improving their accessibility of knowledge through a professional. Glovida-RX represents a significant milestone in Wellchem’s journey.

The platform offers a wide range of products, including prescription medications, pharmacy medications, health supplements, and personal care items. What sets Glovida-RX apart is its dedication to customer education and safety. The online pharmacy ensures that all transactions comply with regulatory standards set by the HSA. Moreover, the platform includes a comprehensive system for verifying prescriptions and maintaining the highest standards of patient safety.

Ms Geraldine and Mr Winthrop, in their interview, emphasised the importance of Glovida-RX in the digital age: “We recognized the need for a more accessible and convenient platform to reach our customers. Glovida-RX is not just an online store; it’s a bridge to better health, providing reliable information and easy access to necessary medications.”

Looking ahead, Wellchem Pharmaceuticals is committed to expanding its reach and enhancing its service offerings. The company plans to invest further in its digital platforms, with Glovida-RX at the centre of its growth strategy. This includes plans to incorporate advanced AI-driven tools to personalise customer experiences.

Moreover, Wellchem aims to continue its legacy of community involvement. The founders believe that business success is deeply intertwined with social responsibility. As part of this commitment, Wellchem actively participates in various community health initiatives, supporting local charities and health education programs.

“At Wellchem, we are not just about selling products; we are about building trust, providing reliable information, and fostering a healthier community,” says Ms Geraldine. This ethos is reflected in the company’s approach to customer service, which prioritises transparency, integrity, and the highest quality standards. For five decades, Wellchem Pharmaceuticals has been a cornerstone of Singapore’s healthcare industry, providing essential medications and healthcare products to millions. Under the visionary leadership of Ms Geraldine and Mr Winthrop, the company has not only adapted to the changing landscape but also set new standards for excellence in the pharmaceutical sector.

As it looks to the future, Wellchem remains committed to innovation, growth, and community engagement. With its digital platform, Glovida-RX, the company is well-positioned to lead the next wave of digital healthcare, making high-quality medication more accessible to all. Wellchem Pharmaceuticals continues to exemplify what can be achieved with dedication, innovation, and a passion for public health. Its journey from a small wholesaler to a leader in digital healthcare is a testament to its enduring commitment to improving the quality of life for people across Singapore and beyond.
