Minimally Invasive Surgery for Total Knee Replacement

Here are some key points about this technique:

Preservation of the Vastus Medialis: One of the distinguishing features of this approach is that it avoids dividing the vastus medialis muscle from the rest of the quadriceps muscle. Instead, the surgeon lifts the muscle from its inferior boundary and gently retracts it without cutting. This technique is intended to minimise trauma to the muscles around the knee.

Benefits:  The minimally invasive approach offers several potential advantages for patients, including faster recovery, improved strength, and reduced postoperative pain. By preserving the integrity of the quadriceps muscle, patients may experience less muscle weakness after surgery.

Cosmetic Advantage: Another benefit is the cosmetic aspect of the procedure. The incision for this minimally invasive technique is typically smaller, usually around four inches, and can be tailored to the patient’s specific needs and size. This can result in a smaller, more inconspicuous scar.

Limitations: It’s important to note that this technique is not suitable for all cases. It is typically not used in complex cases involving the correction of severe deformities or the revision of failed knee implants. In such situations, the surgeon may need to make a larger incision to ensure adequate exposure for the necessary procedures.

Patient-Centred Approach: Dr. Chhallani emphasises the importance of selecting the most appropriate surgical technique for each patient’s unique situation. While the minimally invasive approach is favoured whenever feasible to spare tissue and minimise dissection, the surgeon is also prepared to extend the incision if necessary to ensure that the surgery is performed safely and effectively. Overall, minimally invasive total knee replacement, as described by Dr. Abhay Chhallani, represents a patient-focused approach that balances the benefits of minimal tissue disruption with the need for effective surgical outcomes in complex cases. It is important for patients to discuss their individual circumstances and surgical options with their healthcare provider to determine the most suitable approach for their knee replacement surgery.
