What is Partial Knee Replacement Surgery?

Partial knee replacement, sometimes called unicompartmental knee replacement, is a surgical procedure that replaces only the damaged portion of the knee joint. Instead of resurfacing the entire knee, only the worn-out surfaces of one or two compartments are replaced while the healthy bone, cartilage, and ligaments are preserved.

This procedure is generally recommended for patients with arthritis limited to one or two compartments of the knee, such as osteoarthritis affecting only one side. Compared to total knee replacement, it is less invasive, preserves more of the natural joint, and involves less bone removal. Under the care of Dr. Jigar Sundesha , patients receive a highly personalized approach and advanced treatment.

*Suitability depends on individual assessment—your surgeon will advise the best option.

Benefits of Partial Knee Replacement

• Smaller incisions and less bone removal result in reduced trauma to the joint.
• Faster recovery and shorter hospital stay — most patients walk with support in just a few days.
• Quicker return to daily activities, often within 4–6 weeks.
• Preservation of natural ligaments and bone, giving the knee a more natural feel and function.
• Reduced risk of long-term complications like stiffness, loosening, or instability.

*Final cost may vary depending on implant choice and hospital stay.

Longevity of Partial Knee Replacements

Partial knee implants typically last 15–20 years, depending on factors such as the patient’s age, weight, lifestyle, and implant positioning. Advances in implant design and surgical precision have shown some replacements lasting over 25 years. Dr. Jigar Sundesha emphasizes accurate implant placement and ongoing follow-up care to maximize the life of the prosthesis.

*Longevity depends on multiple factors including activity level, body weight, and implant type. Routine check-ups and proper rehabilitation help detect issues early and extend implant life.

Recovery After Surgery

Most patients begin walking with assistance within a few days of surgery. Physiotherapy plays an essential role in strengthening the joint, and light activities can usually be resumed within week. Full recovery takes around 4-6 weeks, with stability and comfort returning by 6–8 weeks.

*Recovery speed may vary depending on age, overall health, and commitment to physiotherapy.

Implant Durability

Modern partial knee replacement implants provide excellent long-term results. While most last for decades, there is still a small risk of wear or loosening over time, which may require revision surgery. Consulting an experienced orthopedic surgeon like Dr. Jigar Sundesha helps ensure the best implant choice and long-term expectations.
