Surgical methods for patellar fractures

The patella is a bone and flesh in the knee joint. It is needed to complete various activities of the human foot. Everyone has to stand for so long and walk so much every day, which leads to the interruption of the service life of the patella, followed by a series of diseases. Patellar fractures can also cause arthritis. Let’s take a look at the treatment methods of patellar fractures.

Patellar fracture has a high incidence and is one of the common orthopedic injuries. With the rapid development of orthopedic trauma emergency technology, the treatment effect of patellar fractures has been significantly improved. In recent years, the research on surgical treatment of patellar fractures has gradually increased, and many new surgical procedures and internal fixators have been used in clinical practice, all of which have achieved certain therapeutic effects. There are many surgical methods at present, each with its own advantages and disadvantages, and there is no universally recognized surgical procedure for patellar fractures.

Patellar fracture is a common intra-articular fracture in clinical practice, and its incidence has a clear increasing trend. The cause of the disease is direct or indirect violence. The patella is responsible for maintaining the stability of the knee joint, transmitting and enhancing the strength of the quadriceps, etc., so the clinical treatment requirements for patellar fractures are relatively high. Currently, the internal fixation of patellar fractures in clinical practice mainly adopts wire cerclage, tension band, patellar convergence device internal fixation, external fixator external fixation, etc.

The treatment of patellar fracture should restore the smoothness of the articular surface to the greatest extent possible, provide firmer internal fixation, mobilize the knee joint early, and prevent the occurrence of traumatic arthritis.

1. Non-surgical treatment

Plaster splint or tube fixation is suitable for non-displaced patellar fractures. No manual reduction is required. The blood in the joint is drained and bandaged. The affected limb is fixed in an extended position for 3 to 4 weeks with a long-leg plaster splint or tube. Practice quadriceps contraction during the cast period, and practice knee flexion and extension after the cast is removed.

2. Surgery

Patellar fractures with more than 2 to 3 mm displacement, articular surface unevenness of more than 2 mm, and combined extensor retinaculum tear fractures are best treated with surgery.

In more serious cases of patellar fracture, surgical treatment is required, but there are many surgical methods, so the specific one to be chosen needs to be based on the patient's condition. Therefore, it is recommended that you take a proper rest at ordinary times, do not let the patella work for too long, and eat more calcium-rich foods.
