Globally, knee replacement accounts for 17% of all orthopaedic procedure revenue. In Uganda, this segment is growing as osteoarthritis prevalence increases with an ageing population and rising obesity rates. The demand for total knee replacement (TKR) and unicompartmental knee replacement is creating new requirements for hospital procurement.
Why knee replacement demand is growing
Osteoarthritis of the knee is the most common indication. Additional drivers include rheumatoid arthritis, post-traumatic arthritis (often following untreated fractures), and avascular necrosis. As awareness of knee replacement as a treatment option grows among patients and surgeons, procedure volumes are increasing.
Implant selection
Modern knee prostheses are available in cruciate-retaining (CR) and posterior-stabilised (PS) designs. Fixed-bearing polyethylene inserts remain the standard, while high-flex designs are important for patients who kneel for prayer or daily activities. Cobalt-chromium femoral components with UHMWPE tibial inserts are the most common material combination.
Surgical considerations
Accurate component alignment and soft tissue balancing are critical to implant longevity. Instruments for intramedullary and extramedullary alignment, along with appropriate sizing guides, are essential complements to the implant system itself.
Expanding access
As more hospitals in Uganda develop joint replacement capabilities, the need for locally stocked, NDA-registered knee prostheses and associated instrumentation will only grow.
