Our Summary
This study aimed to figure out if using patient-specific guides (PSGs) can help improve the accuracy of bone cuts in total knee replacements for dogs, as compared to generic guides. Sixteen legs from dead medium to large breed dogs were used. The legs were randomly divided into two groups of eight, one group using the standard guides and the other using custom 3D-printed guides. The study found that using PSGs did improve the accuracy of cuts in the tibia (the larger bone in the lower leg) but not in the femur (the thigh bone). The use of PSGs also improved the cutting of the front and bottom parts of the femur. However, it did not affect the inward or outward tilt. The results suggest that PSGs could be useful in dog knee replacements. Now, clinical trials are needed to see if these benefits actually improve joint function and the lifespan of the implant.

Doctor’s Tip
A doctor may advise a patient undergoing knee replacement surgery to follow their post-operative rehabilitation plan carefully, including completing prescribed physical therapy exercises to help strengthen the surrounding muscles and improve range of motion in the knee. It is important for patients to communicate openly with their healthcare team about any concerns or difficulties they may be experiencing during the recovery process to ensure the best possible outcome.
Suitable For
Patients who are typically recommended knee replacement surgery are those who have severe knee pain and stiffness that limits their daily activities, have not seen improvement with other treatments such as medication or physical therapy, have significant damage to the knee joint due to arthritis, injury, or other conditions, and have good overall health and are willing to commit to the rehabilitation process after surgery.
Timeline
Before knee replacement:
- Patient experiences chronic knee pain, stiffness, swelling, and limited mobility
- Patient undergoes various non-surgical treatments such as physical therapy, medications, and injections to manage symptoms
- Patient and their healthcare team decide that knee replacement surgery is the best option to improve quality of life
After knee replacement:
- Patient undergoes pre-operative appointments, tests, and education to prepare for surgery
- Patient undergoes knee replacement surgery, which involves removing damaged cartilage and bone and replacing it with artificial components
- Patient stays in the hospital for a few days for recovery and physical therapy
- Patient continues physical therapy and rehabilitation at home or in a rehabilitation facility to regain strength and mobility
- Over time, patient experiences reduced pain, improved mobility, and better quality of life as the knee heals and the artificial joint functions effectively.
