Most people with a patellar fracture can make a full recovery with proper treatment and will experience no significant limitations in their daily activities. However, some patients are not so fortunate; this may be due to incomplete treatment or a failure to follow a scientifically sound and reasonable postoperative exercise regimen, which can lead to complications and cause them significant suffering.

01 Complications Following a Patellar Fracture

A patellar fracture may lead to traumatic patellar arthritis. If the fracture is severe, or if the surfaces do not align properly after medical reduction, this can cause significant pain in the patella. If an X-ray reveals increased bone density in the area and a narrowing of the joint space, this indicates traumatic patellar arthritis. For patients with mild pain and relatively mild symptoms, medication may be sufficient. However, if the condition is severe, a second surgical procedure may be necessary.

A secondary fracture may occur following a patellar fracture. The probability of this happening is not very high, primarily because the original fracture has not fully healed, resulting in poor stability of the knee joint. When the patient attempts to walk, they may suddenly feel their leg give way and be unable to bend the knee. Although the brain knows what to do, it cannot control the affected leg, and the patient is unable to prevent a fall. A combination of factors can lead to a re-fracture of the patella. If the re-fracture is minor or merely a hairline crack, it can be stabilized with a cast. However, if the fracture is severe—or if there is bone displacement—a second surgery will be required to perform internal fixation.

After a patellar fracture, some patients may experience delayed or non-union. The probability of this occurring is not very high. Generally, patients can make a full recovery within 4 to 6 weeks; however, a very small percentage of patients still show no signs of healing even after 6 weeks, which is classified as delayed or non-union. If symptoms are mild, conservative treatment is used; if the condition is severe and pronounced, surgical intervention is required.

02 Lifestyle Taboos to Be Aware Of

Patients with patellar fractures must avoid excessive knee movement in their daily lives. This includes activities such as hiking or climbing stairs. If such activities cannot be avoided, patients should make sure to get plenty of rest and, ideally, wear a knee brace. Patients should also manage their weight, as excessive body weight places additional strain on the knee. In addition, patients should pay attention to their diet, opting for light, well-balanced meals, as this will aid in the recovery from the fracture.

03 How to Exercise Scientifically

Exercise 1: Lunges

Key Points: Start in a standing position with your upper body upright and hands on your hips. Stand with your legs apart, shifting your weight onto your front supporting leg. Squat down as you inhale, and stand up as you exhale. Throughout the movement, keep your knees aligned with your toes. Repeat this exercise, performing 2 sets of 10 repetitions each.

Exercise 2: 45-Degree Straight-Leg Raise

Key Points: Lie on your back with your upper body stable and arms at your sides. Raise the affected leg straight up to a 45-degree angle, then lower it slowly, taking care not to exceed 45 degrees. Repeat this exercise, performing 2 sets of 12 repetitions each.

These two exercises can help improve lower limb joint stability, restore limb function, and increase overall strength. You only need to do them 2 to 3 times a day, but be sure to wait at least 40 minutes after a meal before starting, otherwise it may interfere with digestion.

In our view, no matter what type of fracture you’ve experienced, a long rehabilitation period is inevitable. We recommend that you approach your rehabilitation exercises with patience. As long as you follow your doctor’s instructions and take postoperative care seriously, you will surely make a full recovery and regain your health!
