Description
The invention belongs to the field of orthopedic surgical tools, and particularly relates to a structure of a quantitative excision tool for a fat pad below a patella.
Background
The statistics of the 2013 year end by the national statistical office of China shows that the population of China is 136072, the population of China is 20243 ten thousand, 14.9% of the population, and the population of China is 13161 ten thousand, 9.7% of the population. Beginning in 2013, the number of the aging population in China is increased in 1000 ten thousand scale, and the future 20 years are doubled by 4 hundred million. According to the statistical data, 51% of the elderly people over 60 years old in China have knee osteoarthritis. In the united states, over 900 tens of thousands of people are diagnosed with gonarthritis via clinical symptoms and imaging data. In addition to traumatic arthritis, rheumatoid arthritis, etc., a large number of elderly patients experience knee joint disease. Early-stage conservative treatment methods for knee joint diseases mainly include lifestyle changes, physical therapy, weight loss, nonsteroidal anti-inflammatory drugs, orthopedic shoes, walking sticks, closed treatment, etc. [2]. Knee arthroplasty is an important treatment for elderly knee joint disease patients in the middle and late stages. With the continuous deep development of reform, the comprehensive strength of the country is continuously improved, and most three-level hospitals in China can perform artificial total knee joint replacement operation. At present, whether the patellar fat pad is reserved in the artificial total knee replacement operation at home and abroad is still in great debate, and long-term clinical follow-up data is lacking.
The patellar inferior fat pad is positioned behind the patellar ligament, between the intercondylar anterior region and the lower portion of the patellar surface of the femur, and has the functions of pad and lubrication. The external side of the blood vessel network of the patellar fat pad is composed of an external artery below the knee and an external artery below the knee, and the internal side is composed of an internal artery ascending branch below the knee, a descending branch of an upper patellar branch of an artery below the knee and a lower patellar branch of a joint branch of the artery below the knee. Lin Yujin it is shown that the fat pad under the patella is different from fat tissue at other parts of the whole body, and contains rich blood vessel network, which not only nourishes itself, but also provides blood for adjacent tissue structures such as patella ligament, patella inferior pole, etc. Studies by nemschk et al indicate that the rich vascular network in the infrapatellar fat pad is an important vascular source for the patella. Research by Ushiyama and the like shows that the infrapatellite pad is rich in nerves and immune cells and has the function of producing inflammatory factors and growth factors. Excessive excision of the infrapatellite pad in total knee replacement can cause biomechanical changes of the knee joint, resulting in reduced patella height, shortened patellar ligament, anterior knee pain, even ischemic necrosis of the patellar ligament, fracture of the patella, and the like, the reason of which is closely related to injury of blood supply of the infrapatellite pad. Therefore, preserving the fat pad below the patella during the artificial total knee replacement operation is currently the main academic claim at home and abroad. However, there is no tool currently available to quantitatively resect the infrapatellar fat pad, thereby completely preserving the dense vascular region.

Method of operation
1) Film shooting preset cutting height
Firstly, observing the height of a dense blood tube region of the patellar fat pad according to a radiograph, wherein the dense blood tube region of the patellar fat pad is positioned at the inner side and the outer side of a patella of the patellar fat pad and is opened by 5mm, the distance from the tip of the patella is 14mm, the distance from the ligament of the patella is 10mm, comparing the two distances to the approximate range of cutting, and observing whether the front side of the patella is deformed or not, or else, the device cannot be used;
2) First resecting part of the patellar fat pad
In the operation, the epidermis is cut and turned to one side, so that the patellar fat pad is exposed to the visual field, and the patellar fat pad at the upper part is firstly resected by a knife, so that the knife is easy to lower.
3) Mounting and adjusting the position of the cutting tool
Clamping the outer side of a patella by using a caliper 5, placing a patella ligament measuring rod 3 on a patella ligament, inserting and fixing by using a fixed tooth 18, installing a excision knife 4 on a positioning rod 2, inserting a connecting clamp 21 at one end of the positioning rod 2 into a connecting hole 14, inserting a balance hole 17 at the other end into an installation convex block 18, observing to ensure that the positioning rod 2 is horizontally placed, vertically placing the positioning rod and the balance rod, if the positioning rod is inclined, holding the caliper 5 for adjustment until the positioning rod 2, a connecting rod and the balance rod are vertical, and if the positioning rod is not enough, connecting a clamping block to move left and right for fine adjustment;
4) Adjusting the cutting height
Fine adjustment is carried out according to the actual position, the lifting knob 12 is rotated, the height of the lifting rod 7 is adjusted, and the proper lifting height is ensured;
5) Resecting the fat pad under the patella
The positioning rod 2 is taken down, the patellar ligament measuring rod 3 is taken away, the positioning rod 2 is put back, the resectoscope 4 is fixed at the lower end of the positioning rod 2, so that the resectoscope needs to be slowly put in during the returning, the moving block is held by a hand to move back and forth for cutting until the cutting is completed, and the patellar fat pad at the upper end after the cutting is taken away by pliers and the like.
Effect of operation
The infrapatellar fat pad is rich in nerve and immune cells, and has the function of producing inflammatory factors and growth factors. Excessive excision of the infrapatellite pad in total knee replacement can cause biomechanical changes of the knee joint, resulting in reduced patella height, shortened patellar ligament, anterior knee pain, even ischemic necrosis of the patellar ligament, fracture of the patella, and the like, the reason of which is closely related to injury of blood supply of the infrapatellite pad. During the artificial total knee replacement operation, we find that the complete retention of the fat pad under the patella can affect the operation, and that part of patients can have symptomatic postoperative ringing, and that few patients have the ringing disappeared after the fat pad is removed under the arthroscope, so that the detailed information is not yet available in the international research on the excision of the fat pad under the patella, whether, how much and how to be excised.
In total knee arthroplasty, ischemic contracture of the patellar tendon caused by excision of the subpatellar fat pad is one of the important reasons for postoperation low-position patella and patellar tendon contracture. Resecting the infrapatellar fat pad during total knee replacement can result in a decrease in post-operative patella height, resulting in shortening of the patellar tendon and lower patella. The fat pad below the patella should be kept as much as possible in the total knee arthroplasty, and the damage to the fat pad below the patella and the surrounding tissues thereof can be reduced by the accurate operation and correct treatment in the operation, so that more satisfactory operation effect can be obtained.
It has been found that total removal of the infrapatellar fat pad results in a significant decrease in the angle of tibial supination and significant inward movement of the patella during extension of the knee, with reduced pressure at the patella point, to a greater extent when the knee is flexed than when the knee is extended. They therefore believe that the fat pad has biomechanical functions that can alleviate the symptoms of the pre-knee pain syndrome, the biomechanics of the patella and knee joint kinematics can be affected after resection. The infrapatellar fat pad plays an important role in maintaining blood supply of adjacent structures, and should be kept as much as possible in the preoperative plan.
Excessive excision of the subpatellar fat pad in TKA surgery can lead to complications such as patellar ligament, patellar ischemia, postoperative patellar fracture, patellar ligament shortening, and the like, which are obviously increased. It was found by angiographic studies on cadavers that complete resection of the infrapatellar fat pad resulted in blockage of blood supply to the inferior half of the patella. 1-3 years after the patellar fat pad is resected in the knee joint replacement operation, the measured patellar ligament length is obviously shortened by 2-3 mm compared with the length before operation, which accounts for about 5%, and the preservation of the patellar fat pad is considered to be one of the important factors for reducing the patellar lower pole fracture after the TKA operation. In the clinical relationship between the anatomical structure of the infrapatellar fat pad, it is most authoritative to maintain the infrapatellar fat pad as much as possible in TKA surgery to maintain blood supply to the adjacent structure. Excessive removal of the infrapatelectasis can cause biomechanical changes in the knee joint, leading to pain in the front of the knee, sometimes shortening of the patellar ligament, and even ischemic necrosis of the patellar ligament and fracture of the patella. The infrapatellar fat pad is considered to have a direct protective effect on the patellar tendon, and meanwhile, fatty liver cells in the infrapatellar fat pad have an important effect on the repair of the patellar tendon and have a great influence on the occurrence of low-level patella. The mechanical movement of the patellofemoral joint is obviously changed by the low-position patella, so that the patellofemoral joint is abnormal. The patellar inferior pole can collide with the tibia, and the pressure of the patellofemoral joint can be increased due to the downward movement of the patella. Studies have shown that preserving the fat pad below the patella is beneficial in reducing the occurrence of wound complications.
Trauma, abrasion, inflammation and the like cause the infrapatellar fat pad to edema and hyperplasia, form pinch or impact on the tibiofemoral joint and/or the patellofemoral joint, can cause Hoffa disease, and present a series of clinical symptoms, and can involve related synovial membranes and tendons. When the fat pad is stimulated by a certain factor, acute and chronic injuries can generate aseptic inflammation to cause pain, edema, hemorrhage, exudation, hyperplasia, hypertrophy and hardening, and fibrous tissue between the fat pad and the patellar ligament is denatured, adhered, mechanized and lose elasticity, so that the knee extension activity is limited, and the knee pain can be caused by the chemical stimulation of the rich nerve endings caused by the inflammation. Studies have shown that infrapatellar fat pad fibrosis has a significant correlation with pain in front of the knee after TKA surgery, and infrapatellar fat pad fibrosis affects knee joint mobility. Many specialists consider adequate exposure to be more beneficial for TKA surgery. Studies have shown that there is no significant difference in postoperative complications from the removal of the infrapatellar fat pad compared to the retention of the fat pad, except that the patient has a slightly higher probability of pain in front of the knee, suggesting that the infrapatellar fat pad can be retained without affecting the surgeon's exposure to the incision, and vice versa.
At present, the Insall-Salviti index is the most commonly used index for evaluating the patellar tendon shortening after TKA operation in clinic, but the acquisition of the Insall-Salviti index requires a patient to take a knee joint lateral slice when bending a knee by 30 degrees, however, no special tool is available for a radiologist in the market at present, so that the research and development of a special excision tool becomes a powerful guarantee for accurately acquiring the Insall-Salviti index.
The device can be used for judging the degree of excision according to preoperative analysis, comparison and quantification, and the excision amount can be regulated in the operation, so that the dense vascular area of the fat pad below the patella is kept, the accurate excision of the fat pad below the patella is ensured to be particularly important, and the occurrence of complications in the future is avoided. The individual differences are different, so that the example cannot be used as a comparison, but the recovery degree of the preserved patellar ligament is obviously better than that of the patellar ligament which is not subjected to quantitative working operation in operation, and the probability of shortening the patellar ligament is much smaller.
