Software-Guided Surgery at Lake District Hospital
At Lake District Hospital,our goal is to offer advanced and value-added treatment options to our patient population. With Orthopedic Software-Guided Surgery we can deliver on that promise. Our surgeons can place knee and hip implants with products that are designed to achieve more precision and confidence. This may result in better clinical outcomes and accurate positioning of the implants. [1, 2, 3]
Osteoarthritis is the most common reason for people to undergo a hip or knee replacement surgery. Nearly 2.9 million joint replacement procedures are performed globally each year, including more than 1.4 million hip and 1.1 million knee replacements. By the year 2030, the number of total knee replacements is expected to reach about 3.5 million and hip replacements are also expected to increase dramatically to approximately 570,000.
Orthopedic Software-Guided Surgery is powerful surgical navigation technology from Brainlab that provides our orthopedic surgeons with critical information needed to perform knee and hip surgeries with greater precision and enhanced alignment. Surgeons are able to more effectively plan orthopedic procedures and offer substantial benefits for patients.
Surgical navigation for hip and knee joint replacement offers many benefits to surgeons and their patients:
Can lead to decreased blood loss due to minimally invasive approaches 
Provides alignment information and helps to improve positioning of the implant components 
Can be a valuable tool for the implant positioning for knees with large deformities [7,8]
Enables balancing of the knee with software guidance
Helping accurate restoration of leg length and offset [9,10]
Intra-operative assessment of range of motion  · More control in minimally invasive surgery  · Supporting accurate positioning of the implants [2,3]
Lake District Hospital will use Orthopedic Software-Guided Surgery as the new standard of care, potentially reducing the risk of repeat, or revision, surgery and helping to improve the overall functionality of the new joint. Software-Guided Surgery for joint replacement is an established and proven tool used to minimize the challenges of accuracy and reproducibility, and enhance the overall functional outcomes.1
The computer software allows surgeons to plan and simulate the joint replacement before any incision has been made on the patient. The software recommends the size and position of the implant based on actual patient anatomy, aiming at proper alignment with the new prosthetic to promote natural joint movement. Physicians are able to react intra-operatively to the surgical situation by verifying what has been done after each step, potentially correcting any imperfections during the procedure.
