Rehabilitation After Knee Surgery

Postoperative Rehabilitation Protocol

Immediate knee mobilization is critical to increase joint range of motion and reduce pain, with early full weight-bearing exercises encouraged to progress as tolerated, according to the British Journal of Sports Medicine guidelines 1
A rehabilitation protocol should include isometric quadriceps strengthening from the first postoperative week, progressing to concentric and eccentric exercises in closed kinetic chain, with neuromuscular electrostimulation added to isometric strengthening in the initial 6–8 weeks 1
Closed kinetic chain exercises should be prioritized in the first postoperative month, with open kinetic chain exercises added as early as 4 weeks, and strength and motor control training combined in the rehabilitation protocol 1
Plyometric and agility training, as well as core stability exercises, may further improve subjective function, functional activities, and functional outcomes 1

A multimodal approach to pain management following TKA is recommended, including general anesthesia combined with a femoral nerve block, supplementation with paracetamol and non-steroidal anti-inflammatory drugs, and intravenous strong opioids for high-intensity pain, as per the Anaesthesia guidelines 2

A thorough evaluation for infection, including laboratory markers and joint aspiration if infection is suspected, is essential before proceeding with TKR 3
Vascular assessment, especially in patients with diabetes or known vascular disease, is crucial for optimal outcomes 4
Evaluation of bone quality is necessary, as poor bone stock may require specialized implants or techniques 4
Assessment of neurological status, particularly in patients with neuropathy, is vital for postoperative success 4
Proper alignment of the prosthesis is critical for long-term success, although the strength of evidence for this is not provided in the given text, it is a general principle in orthopedic surgery 3
Higher surgeon and hospital procedure volumes are associated with better outcomes, indicating the importance of experience in TKR surgery 4

Isokinetic quadriceps and hamstring peak torque at 60°/s should display 100% symmetry for return to high demand activities, according to the British Journal of Sports Medicine guidelines 1
Patient satisfaction is a key outcome measure, with satisfaction rates ranging from 75% to 89% according to the American College of Radiology 3
Thromboprophylaxis with appropriate anticoagulation is recommended to improve outcomes, as suggested by the Praxis Medical Insights 4
In cases of unexplained pain, reoperation is unwise and frequently associated with suboptimal results, as stated by the American College of Radiology 3
