The patellar claw can only be removed after the fracture has healed, and most recommend that the patellar claw be removed surgically 6-12 months after the fracture has healed completely. The surgery is usually performed under continuous epidural anesthesia or lumbar anesthesia, and the stitches are usually removed about 2 weeks after surgery, and the knee can be fully weight-bearing in 2-3 days after surgery, or partially weight-bearing with a single crutch if necessary. Muscle strengthening exercises are also needed to restore thigh muscle strength, usually with straight leg raises in bed. Bed rest is recommended with pillows to elevate the lower extremities to aid venous and lymphatic return to promote swelling. At the same time, it is recommended to use blood-activating drugs to help recovery, such as oral Panlong VII tablets.
