Description

Technical Field

[0001] The present application relates to the technical field of methods for treating bones or joints, and in particular to an improved quadriceps tendon oblique cutting method, and also to a system. Background Art

[0002] Hemophilia is an X-linked recessive bleeding genetic disease caused by gene mutations leading to a deficiency of coagulation factor VIII (FVIII) (hemophilia A) or a deficiency of coagulation factor IX (FIX) (hemophilia B). Hemophilic arthritis itself has its own particularity. Most patients are young and have a long history of illness. They have repeated and progressive bleeding in the joints, which eventually leads to joint deformity, stiffness, ankylosis, severe limited movement and abnormal gait. Long-term limited joint movement and joint bleeding lead to fibrosis of the soft tissue around the knee joint and muscle atrophy, resulting in adhesion of the entire joint. When performing total knee replacement surgery, it is first necessary to open the joint cavity to obtain a better surgical field of view, and at the same time obtain a knee joint with better joint function through surgery.

[0003] Currently in clinical practice, the rectus femoris oblique cutting technique has been widely used in TKA surgery for hemophilic arthritis and has achieved good clinical results. However, for some TKA of stiff and ankylosing knee joints, the rectus femoris oblique cutting technique can only solve the problem of surgical exposure and cannot improve the postoperative function of the knee joint. Therefore, even with this scheme, the postoperative function is generally poor and it is difficult to obtain better postoperative function. The key is that the traditional rectus femoris oblique cutting technique cannot effectively lengthen the quadriceps femoris, and thus cannot improve the length of the knee extensor mechanism, and therefore cannot improve the flexion activity on this basis. Summary of the invention

[0004] The inventors have found through research that common soft tissue deformities in hemophilic arthritis are flexion contracture deformities of the elbow, knee and hip joints, Achilles tendon contracture and clubfoot deformity. Among them, the knee flexion contracture has the greatest impact on the patient's walking and daily life. Flexion contracture deformity will seriously affect the patient's gait and also have a great impact on the function of the joints. Severe flexion contracture deformity is a severe challenge for hemophilic arthritis patients undergoing total knee replacement surgery, especially for patients with ankylosing or stiff knee joints due to flexion contracture. The difficulty of total knee replacement surgery is significantly increased and there are more perioperative complications.

[0005] The purpose of the present application is to provide an improved quadriceps tendon oblique cutting method and system to solve the technical problem that the prior art cannot provide a method for effectively lengthening the quadriceps femoris and improving flexion activity.

[0006] According to one aspect of the present application, an improved quadriceps tendon oblique cutting method is provided, the method being executed by a processor, comprising:

[0007] Obtain a traditional bevel cutting path and obtain a traditional path data set;

[0008] Obtain an extended incision path and obtain an extended path data set;

[0009] Perform a dataset merge on both the traditional route dataset and the extended route dataset.

[0010] In some embodiments, the extended path dataset includes at least a medial quadriceps femoris interrupted extended incision path.

[0011] According to another aspect of the present application, an improved quadriceps tendon beveling system is provided, the system being controlled by a processor and comprising:

[0012] A first acquisition module, the first acquisition module is at least used to acquire a traditional beveling path and obtain a traditional path data set;

[0013] A second acquisition module, the second acquisition module is at least used to acquire an extended incision path and obtain an extended path data set;

[0014] An execution module is used to perform data set merging on the traditional path data set and the extended path data set.

[0015] In some embodiments, the first acquisition module is data-connected with the second acquisition module, and the execution module is data-connected with the first acquisition module and the second acquisition module respectively.

[0016] Compared with the prior art, this application has the following advantages and beneficial effects:

[0017] The method of the present application processes the traditional path data set and the extended path data set through a processor, thereby further extending the traditional rectus femoris oblique cutting technology to the proximal end, fully loosening the proximal lateral tendon, and obtaining better surgical exposure during surgery. At the same time, the processor performs data set merging on the traditional path data set and the extended path data set to achieve intraoperative tendon dislocation suturing, which can achieve better joint function improvement during surgery and lay a foundation for postoperative functional recovery.

[0024] The following will be combined with the attached examples of the present application Figure 1-3 The technical solutions in the embodiments of the present application are clearly and completely described together. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0025] Application Overview

[0026] Hemophilia is an X-linked recessive bleeding genetic disease caused by gene mutations leading to a deficiency of coagulation factor VIII (FVIII) (hemophilia A) or a deficiency of coagulation factor IX (FIX) (hemophilia B). Joints or muscles are the most common bleeding sites in hemophilia, and the knee joint is the most common bleeding joint. Moreover, the same joint may bleed repeatedly, eventually developing into hemophilic arthritis, which seriously affects the joint function of the patient. Total knee arthroplasty (TKA) is suitable for patients with hemophilic arthritis who have complete destruction of articular cartilage, even bone destruction and deformity, and end-stage joint lesions (grade IV lesions), and whose pain and limited mobility cannot be relieved. Clinical studies have confirmed that the benefits of TKA surgery for patients with hemophilic arthritis are that it can reconstruct a stable biomechanical anatomical structure of the knee joint, relieve the symptoms of knee arthritis pain, restore the movement function of the knee joint, and improve the social survival ability and quality of life of patients with hemophilic arthritis.

[0027] Based on the above, the present application relates to an improved quadriceps tendon bevel cutting method during total knee arthroplasty (TKA) for the treatment of stiff knee caused by hemophilic knee arthritis, including the design, implementation and intraoperative suturing of the improved quadriceps tendon bevel cutting method, which overcomes the technical deficiencies of the existing general quadriceps tendon bevel cutting method. By changing the position of the quadriceps bevel cutting and optimizing the suturing method after bevel cutting, good surgical field exposure can be achieved in TKA for stiff knee, the length of the quadriceps tendon can be appropriately extended, and a significant improvement in joint mobility during surgery can be achieved, thereby accurately completing the preoperative plan and achieving the expected surgical effect, while laying a solid foundation for postoperative rehabilitation functional training.

[0031] It can be understood that obtaining the traditional oblique cutting path and obtaining the traditional path data set is to obtain the traditional oblique cutting method; obtaining the extended incision path and obtaining the extended path data set is to further extend the traditional rectus femoris oblique cutting technology to the proximal end, obtain the medial discontinuous extended incision of the quadriceps femoris, and retain part of the tendon tissue; performing data set merging on the traditional path data set and the extended path data set is to use the processor to perform tendon suturing in the flexion position of the knee joint, specifically:

Figure 3The blue line in the figure is the improved oblique incision path, in which the angle between the oblique line and the vertical line at the two parts is between 30° and 40°, and part of the soft tissue between the incision edge and the surrounding soft tissue is loosened and separated.
