Each material and design aims to maximize longevity, reduce wear, and improve function. Selection depends on patient factors, lifestyle, and surgeon preference, ensuring personalized treatment for optimal outcomes.

3.3; Intraoperative Care and Anesthesia

Intraoperative care for total knee replacement involves meticulous surgical techniques and anesthesia management. Anesthesia options include general, spinal, or regional blocks, chosen based on patient health and surgical requirements. During surgery, vital signs are closely monitored using ECG, blood pressure, and oxygen saturation. Blood loss is managed with surgical precision and, if needed, transfusions. Pain control is optimized with local anesthetics or nerve blocks. The surgical team ensures proper implant alignment and soft tissue balance for optimal outcomes. Post-operative recovery begins immediately, with anesthesia reversal and transfer to the recovery unit. Effective intraoperative care minimizes complications and sets the stage for successful rehabilitation.

Post-Operative Care and Rehabilitation

Post-operative care focuses on pain management, wound healing, and early mobilization. Physical therapy begins shortly after surgery to restore strength, range of motion, and functional abilities.

4.1. Immediate Post-Operative Recovery and Pain Management

Immediate post-operative recovery focuses on stabilizing the patient, managing pain, and preventing complications. Pain management often includes a combination of oral medications, PCA (patient-controlled analgesia) pumps, and nerve blocks to minimize discomfort. Monitoring of vital signs, wound drainage, and neurological status is critical during this phase. Patients are encouraged to start mobilizing within 24 hours to prevent stiffness and promote blood circulation. Early intervention by physical therapists helps restore knee mobility and strength. Multimodal pain strategies are emphasized to reduce reliance on opioids, ensuring a smoother transition to rehabilitation. Clear communication between healthcare providers and patients is essential to address concerns and facilitate a safe recovery process.

4.2. Early Mobilization and Weight-Bearing Exercises

Early mobilization is crucial for restoring knee function and preventing complications. Patients are typically encouraged to begin weight-bearing exercises within 24-48 hours post-surgery, depending on their surgeon’s protocol. Weight-bearing status (e.g., partial or full) is determined based on the surgical technique and patient stability. Gentle exercises, such as heel slides, straight leg raises, and ankle pumps, are initiated to improve range of motion and strength. Physical therapists assist with mobilization, ensuring proper alignment and minimizing discomfort. Early ambulation with assistive devices, like walkers or crutches, promotes independence and reduces the risk of prolonged bed rest. Progression of exercises is tailored to the patient’s recovery pace, focusing on functional activities to enhance recovery outcomes and prepare for more advanced rehabilitation phases.
