Recent Mergers & Acquisitions

In mid‑July 2025, Zimmer Biomet agreed to acquire Monogram Technologies for approximately $177 million, gaining access to FDA‑approved semi- and fully autonomous knee replacement systems. The acquisition is expected to close later in 2025 and become earnings-accretive by 2028, reinforcing Zimmer’s position in surgical robotics 

Smith & Nephew continues to face pressure from activist investors who are urging the company to consider spinning off its orthopaedics division due to declining performance in key markets, particularly China, where procurement reforms have impacted sales and margins

Recent Market Developments

The market was valued at around USD 10.61–10.75 billion in 2023 and is forecast to expand to USD 16.4–16.5 billion by 2032, growing at a CAGR of approximately 4.9–5.0% . Forte Business Insights projects growth from USD 12 billion in 2025 to USD 16.17 billion by 2030 at 6.1% CAGR 

Technological innovations are rapidly reshaping the field. Robotic-assisted surgery is expanding—Stryker’s Mako platform now handles nearly 95% of robotic-assisted knee replacements in the U.S., prompting global adoption. In 2023, Stryker launched next-gen robotic platforms used widely across U.S. hospitals, while Zimmer Biomet introduced personalized knee implants in 2024, improving outcomes by 20%. DePuy Synthes expanded its portfolio with 3D-printed implants in 2024, capturing notable adoption in Europe . India’s Meril launched a robotic system (MISSO) in mid-2024 that uses automated bone resection and 3D planning to enhance knee implant precision.

Funding & Investment Activity

While full funding data specific to knee-implant manufacturers isn’t broadly disclosed, significant investments are directed toward surgical robotics, precision imaging, and ASCs (ambulatory surgical centers). New entrants—such as startup robotics firms and 3D-custom implant developers—are attracting venture interest and strategic backing from larger M&A-minded device companies.

Recent Market Developments Continued

Fixed-bearing implants lead prosthesis design, with around 57% market share in 2023, favored for long-term stability and cost-effectiveness. Total knee arthroplasty (TKA) dominates the procedural mix (64–71% share), followed by partial and revision procedures. Hospitals account for about 63–65% of procedures in 2023, but ambulatory surgical centers are the fastest-growing end-user segment due to reimbursement shifts and outpatient procedural models.

Regionally, North America continues to dominate (41–51% share), driven by high procedure volumes and rapid adoption of robotic systems. Meanwhile, Asia-Pacific—especially China, India, and Japan—is the fastest-growing region, with emerging infrastructure and population aging trends fueling demand. Germany, in particular, leads Europe due to advanced surgical techniques and aging demographics.

Funding & Investment Activity

Beyond organic investments, the high growth of robotics-linked makers and custom implant startups has drawn attention. Venture capital flows and strategic acquisitions (such as Zimmer’s Monogram purchase) underscore investor confidence in tech-enhanced orthopaedics.

Conclusion

The knee replacement market is entering a dynamic growth phase fueled by aging populations, rising osteoarthritis incidence, and advancements in robotics, 3D-printed implants, and minimally invasive techniques.
