What Can I Expect from Orthopedic Knee Surgery?

Artificial knee arthroplasty is a new technology for the treatment of knee joint diseases that has gradually developed after the successful application of modern artificial hip joints to patients. It can very effectively eradicate advanced knee joint pain and greatly improve the quality of life of patients. Countries are more popular.

Osteoarthritis knee arthroplasty knee replacement

To evaluate the effect of artificial total knee arthroplasty on severe knee osteoarthropathy. Methods The clinical data of 32 patients with severe knee osteoarthropathy treated by total knee arthroplasty with 38 knees were analyzed and summarized. Results According to the American HSS scoring standard, the excellent and good rate of operation was 93.75%. Postoperative pain, joint function, and mobility were significantly improved. Conclusion Artificial total knee arthroplasty is a practical and effective method for the treatment of severe knee osteoarthropathy, but attention should be paid to the selection of indications, correction of varus and flexion deformities of the joints, and proper placement of tibial prostheses to reduce Loose, while performing early functional exercise, strive to reduce postoperative complications. Total knee arthroplasty (TKR) provides an effective treatment for patients with severe knee osteoarthropathy. TKR was performed in 32 cases and 38 knees in our hospital from April 2000 to December 2007

General information This group of 32 patients (38 knees), including 10 males and 22 females; aged 36 to 76 years, with an average of 58.5 years. 25 cases were unilateral, 7 cases were bilateral; 25 cases were left knee, 13 cases were right knee; 23 cases were osteoarthritis, 7 cases were rheumatoid arthritis, and 2 cases were synovial chondromatosis.

1.2 Methods The operation was performed by the same group of people. General or epidural anesthesia was used. The knee joint was routinely taken with a median incision of the knee joint. The lateral paracondylar approach was used to cut and open the sac. The damage was performed with osteotomy and soft tissue balance treatment. The proximal tibia bone defect was repaired with autologous tibial transplantation, and all prostheses were fixed with antibiotic bone cement. The prostheses were Taiwan Union's post-stable prosthesis (16 cases). Scorpio post-stable prosthesis (6 cases), Depuy CR prosthesis (6 cases) and Beijing Beijing Airlines PCA retained posterior cruciate ligament prosthesis (8 cases). The postoperative knee joint was combined with functional exercise of CPM machine.

All 32 patients were followed up for 11 to 62 months, with an average of 46 months. The American HSS scoring system was used to score patients clinically, with a perfect score of 100 points. Among them, 30 points were pain, 22 points were function, 18 points were range of motion, 10 points were muscle strength, 10 points were flexion deformity, and 10 points were unstable. A score of 85 or more is excellent; a score of 70 to 84 is good; a score of 60 to 69 is fair; a score of 60 or less is poor. X-rays of the knee joint were taken routinely and laterally to observe the prosthesis. Of the 32 patients in this group, 22 were excellent (68.75%), 8 were good (25.00%), and 2 were fair (6.25%). Postoperative pain, joint function, and mobility were significantly improved.

1 Indications and contraindications for TKR Indications: Severe knee pain, instability, deformity, severe disturbance of daily living activities, elderly patients who have failed or had insignificant effects after conservative treatment [1]; various sterile knee joints Inflammation, such as rheumatoid arthritis, knee osteoarthritis, a small number of traumatic arthritis; osteoarthritis after the failure of high tibial osteotomy; primary or secondary osteochondral necrosis. Contraindications: The muscles around the knee joint are paralyzed; the knee joint has been fused to the functional position for a long time, and there are no symptoms such as pain and deformity. Relative contraindications include young age, a lot of postoperative activities, obesity, poor surgical tolerance, and more severe

Total knee arthroplasty is a major orthopedic operation. Any cause of venous injury, venous blood flow stasis and hypercoagulable state is a risk factor for venous thromboembolism (VTE). These patients usually have older, surgical Risk factors such as repair and postoperative braking, these patients are extremely dangerous for VTE. The risk of VTE is higher if the tumor is combined. VTE is the third most common cardiovascular disorder worldwide after coronary heart disease and stroke. An investigation of the incidence of deep venous thrombosis after total hip, artificial knee replacement, and hip fracture around 407 patients in 19 orthopaedic centers in 7 countries in Asia shows that the incidence of deep venous thrombosis confirmed by venography is 43.2% . The results of research by Chinese orthopedic experts show that the incidence of DVT after major orthopedic surgery is 30.8% to 58.2%, which is similar to foreign countries.

For hospitalized patients, the risk factors of VTE should be evaluated routinely and targeted preventive measures should be taken. Anticoagulant drugs for drug prevention measures are: factor Xa inhibitors (such as apixaban), unfractionated heparin (UFH), low molecular weight heparin (LMWH), vitamin K antagonists, etc.
