Knee implants can make up 20% to 40% of the cost of a therapy, which makes a significant impact on the procedure margins, especially in today's capitated reimbursement environment. The industry growth can be hampered in emerging economies having relatively low-income levels due to high costs associated with total knee replacement procedures.

The utilization of advanced technology within the devices has increased the cost of the total knee replacement procedures that will be a restraining factor affecting the market value. However, the government in certain developing countries including India is undertaking several initiatives to reduce the prices of the procedures.

The emergence of the COVID-19 pandemic is an unprecedented public health concern and has negatively impacted the total knee replacement market. Preserving essential health care resources was prioritized in the wake of COVID-19, starting from mid-March 2020, wherein the surgeons were instructed to perform only the essential surgical operations. For instance, as per the Journal of Arthroplasty, an estimated 30,000 primary and 3,000 revision knee replacement surgeries were canceled every week in the early 2020.

These numbers showcase the profound impact of COVID-19 on knee replacement surgeries. However, intensive efforts are being undertaken by several healthcare authorities, hospitals, and surgeons to restore the flow of total knee arthroplasty procedures to pre-pandemic levels. ERAS programs (Enhanced Recovery after Surgery) have been developed to shorten hospital stay, morbidity, and surgical complications. Furthermore, with restoring the regular operating volume of surgeries, there will be significant patient inflow due to postponing and cancelation of surgeries earlier. Hence, such changes in surgical practices are poised to help in restoring the surgical volume post-COVID-19 pandemic.

Rising infection rates contributing to an increase in knee revisions will drive the total knee replacement market revenue

Increasing infection rates contributing to the rising knee revisions is one of the prime factors fuelling the market demand. Total knee replacement is classified into four main types such as type 1 (early post-operative), type 2 (late chronic), type 3 (acute hematogenous) and type 4 (positive intraoperative cultures but clinically unapparent infection). The rate of infections associated with total knee replacement has been increasing gradually over the years. For instance, according to the American Academy of Orthopedic Surgeons, serious complications such as infections occur in over 2% of patients. The infections most often occur in the wound site or around the prosthesis and happen during the hospital stay or after discharge of a patient.

The existing standard of care for late chronic infection is a two-stage revision arthroplasty. It involves the removal of the implant and placement of an antibiotic-impregnated cement spacer. Additionally, a course of intravenous antibiotics is offered, and a delayed second-stage revision is conducted. Thus, the continuously increasing rate of post-surgical infections has significantly boosted the demand for total knee replacement procedures that in turn will uplift the product adoption rate.

Numerous benefits offered by primary knee replacement system will stimulate the industry expansion

Primary knee replacement systems segment dominated 83% of the total knee replacement market share in 2020 led by the multiple advantages such as improved mobility, high satisfaction rates, and pain relief among others.

The development of non-invasive surgical procedures that causes minimum pain and offer precise clinical outcomes will drive the demand for these devices.

Growing prevalence of tricompartmental arthritis will spur the business revenue with high product acceptance

The three-compartmental knee implants segment is expected to significantly expand at a 5.7% growth rate through 2027 impelled by the rising prevalence of severe tricompartmental knee osteoarthritis resulting in the increasing number of total knee arthroplasty procedures. Three-compartmental knee devices help in relieving pain while restoring the function of the knee post total knee surgery. Surgeons are significantly giving preference to these implants attributed to around 90% of people undergoing total knee surgery experience reduced pain levels and increases mobility. This high success rate further translates to increased product acceptance and augments patient retention.

Increasing preference for a femoral component in knee arthroplasty procedures will enhance the total knee replacement market growth

Femoral segment exceeded USD 3.9 billion in 2020 on account of the long-lasting results, decreased chances of osteolysis, and reproduces the anatomy of the distal femur. This component is available in several ceramic or metal options and is made up of cobalt-chromium alloys that are considered the most durable. The femoral component curves around the end of the femur so the kneecap can move up and down easily against the bone as the knee bends and straightens. In addition, it has an asymmetrical anterior flange identical to the patellar grove, which is convenient to prevent adjacent dislocation of the patella.

Rising demand for fixed-bearing implants will positively impact the industry revenue

Fixed-bearing implant segment in the total knee replacement market accounted for more than USD 5.6 billion in 2020 owing to the less expensive alternative, allows the patient to stretch the knee, and provides low contact stress. The clinical studies have demonstrated that fixed-bearing total knee arthroplasty shows a promising clinical success over time in relatively inactive elder people. The fixed bearing design shows excellent survival rates of up to 95% in a 10-year follow-up. Moreover, lower infection rate, no revisions, and reduced dislocations have positively influenced the product acceptance.

Benefits of posterior stabilized design in knee surgery will augment the product adoption

The total knee replacement market for posterior stabilized design segment valued at USD 3.9 billion in 2020 and is projected to witness 6.2% growth rate till 2027 propelled by the advantages posterior stabilized design offers that includes an improved range of motion and a more stable component interface. In the posterior stabilized design, the cruciate ligaments are removed and parts of the implant substitute for the posterior cruciate ligament. Furthermore, this design is technically less complex, avoids anterior translation in weight bearing conditions, and offers better flexion to the knees. Thus, player in the market focuses on developing such advanced implants in total knee arthroplasty with potential advantages comprising greater posterior femoral rollback and less polyethylene sliding wear.
