Knee arthroplasty surgery detaches damaged cartilages and tissues from the knee joint and replaces it with an artificial knee implant. A partial knee arthroplasty is a substitute to total knee replacement for few people with knee osteoarthritis. In this replacement therapy, only the damaged part of the knee cartilage is resurfaced with a prosthesis, when the damage is restricted to a specific knee compartment. Partial implant components are named for the area of the knee they resurface i.e. lateral unicondylar component, medial unicondylar component, and patellofemoral component.
‘Lateral’ is the outside compartment of the knee joint, which is farthest from the opposite part of the knee popliteal fossa, while ‘Medial’ is the inside compartment of the joint. A patellofemoral surgery resurfaces the back of the patella and replaces the thigh bone using metal piece.
A knee osteotomy can be also included in a partial knee replacement, in which a surgeon adds or removes a wedge of bone to the femur or tibia to take some of the weight off of the damaged part of the knee.
Global Partial Knee Arthroplasty Market– Dynamics
The rising prevalence of knee replacement surgeries is expected to propel the global partial knee arthroplasty market growth. For instance, as stated in the article published on September 24, 2021 on the drug watch a consumer advocacy organization, in the U.S. over 600,000 people undergo total or partial knee replacement surgery every year and the number is continuously growing and is estimated to grow to 3.48 million by 2030.
The increasing launches and approvals of knee systems is expected to boost the global partial knee arthroplasty market growth. For instance, on April 21, 2021, Zimmer Biomet Holdings, Inc. received the U.S. FDA approval for ROSA partial knee system for robotically aided partial knee arthroplasty. On May 20, 2020, Smith Nephew, a global medical technology company launched JOURNEY II Unicompartmental Knee System to provide a customized method to partial knee arthroplasty.
In addition, emergence of robotically assisted partial knee surgeries is also expected to fuel the global partial knee arthroplasty market growth over the forecast period. For instance, on March 14, 2017, Stryker Corporation launched Mako robot in the U.S. to perform partial and total knee replacements surgery.
Furthermore, increasing mergers, agreements, and acquisitions by market players are expected to boost the global partial knee arthroplasty market growth over the forecast period. For instance, on November 24, 2020, Exactech, Inc. signed a distribution agreement with orthopedic manufacturer Bodycad for its Reflex Uni knee in the U.S. This collaboration broadens Exactech’s active intelligence technology platform of personalized, data-driven smart solutions.
These factors are expected to drive the global partial knee arthroplasty market growth over the forecast period.
Global Partial Knee Arthroplasty Market– Regional Insights
North America is expected to dominate the global partial knee arthroplasty market, owing to the growing geriatric population and new launches of partial knee systems. For instance, on September 11, 2017, Zimmer Biomet Holdings, Inc. launched Persona a partial knee system. This launch expanded company’s portfolio of anatomically designed and personalized knee implant systems.
Moreover, Europe is expected to witness a lucrative growth in the global partial knee arthroplasty market due to growing prevalence of osteoarthritis. For instance, according to statistical data provided by Statista a leading provider of market and consumer data in 2019, the occurrence of knee osteoarthritis in Europe was around 419 per 100,000 males and 576 per 100,000 females, making it the most common location of osteoarthritis.
These factors are expected to support the global partial knee arthroplasty market growth over the forecast period.
