Global Partial Knee Arthroplasty Market by Product Type (Unicompartmental Knee Replacement, Patellofemoral Joint Replacement, Bi-Cruciate Stabilized Partial Knee Replacement), by Material (Metal and Alloys, Ceramic, Polyethylene), by End-Use (Hospitals, Ambulatory Surgical Centers, Orthopedic Clinics): Insights & Forecast (2024 – 2030)

As per Intent Market Research, the Partial Knee Arthroplasty Market was valued at USD 2.9 Billion in 2024-e and will surpass USD 5.3 Billion by 2030; growing at a CAGR of 10.6% during 2025 - 2030.

The partial knee arthroplasty (PKA) market is growing rapidly as an increasing number of patients seek less invasive alternatives to total knee replacements. This procedure is primarily used for individuals with osteoarthritis or knee joint degeneration affecting only part of the knee, allowing for preservation of healthy bone and tissue. The popularity of partial knee arthroplasty is attributed to its potential for faster recovery times, reduced risk of complications, and a more natural feeling in the knee post-surgery. With technological advancements and the increasing prevalence of knee-related ailments, the market for partial knee arthroplasty is expected to continue expanding globally.

Unicompartmental Knee Replacement is Largest Product Type Owing to Simplicity and Proven Effectiveness

Unicompartmental knee replacement (UKR) is the largest product type in the partial knee arthroplasty market, driven by its simplicity and proven effectiveness for patients with isolated knee joint degeneration. UKR involves replacing only the damaged part of the knee, usually the medial or lateral compartment, while preserving the healthy tissue and ligaments. This makes it a less invasive option compared to total knee replacement, leading to quicker recovery times and less postoperative pain.

The growing preference for less invasive surgeries, along with UKR’s ability to provide effective pain relief and improved mobility, has contributed to its dominance in the market. Additionally, the procedure is often recommended for younger, more active patients who require a knee replacement but wish to maintain a more natural knee function. As the number of knee surgeries increases and the demand for joint preservation grows, the UKR segment will continue to play a central role in the partial knee arthroplasty market.

Hospitals Are Largest End-Use Segment Owing to High Patient Volume and Specialized Care

Hospitals are the largest end-use segment in the partial knee arthroplasty market, driven by the high patient volume and availability of specialized orthopedic care. Hospitals provide the necessary infrastructure and specialized medical teams required for partial knee arthroplasty procedures, making them the primary healthcare setting for knee replacement surgeries. Hospitals also offer a range of services, including preoperative assessments, surgical procedures, and postoperative rehabilitation, ensuring comprehensive care for patients undergoing PKA.

As knee joint problems become more prevalent, particularly in the aging population, hospitals are seeing a higher number of partial knee arthroplasty procedures. The presence of specialized surgeons and advanced medical equipment in hospitals further contributes to their dominance in the end-use segment. Additionally, hospitals are equipped with the resources to manage potential complications, making them a preferred option for patients undergoing knee surgeries.

North America Is Largest Region Owing to Advanced Healthcare Infrastructure and High Adoption Rates

North America is the largest region in the partial knee arthroplasty market, primarily due to its advanced healthcare infrastructure, high adoption rates of orthopedic procedures, and increasing awareness of partial knee replacement options. The United States, in particular, is a key market, with a significant number of partial knee arthroplasty procedures being performed annually. This can be attributed to the region's well-established healthcare system, high levels of insurance coverage, and a large patient population seeking knee replacement surgeries.

The demand for partial knee arthroplasty is also growing in North America due to an aging population, increased prevalence of knee osteoarthritis, and advancements in surgical techniques and prosthetic materials. The preference for minimally invasive surgeries and the ability to offer quicker recovery times further drive the demand for partial knee arthroplasty in the region. North America is expected to maintain its dominance in the market due to continued innovation and growing patient awareness.
