Knee replacement

A knee replacement is opted for those who have progressive pain or impaired knee function. Knee replacement involves removing the injured or damaged knee bone, cartilages and ligaments from the knee and replacing it with an artificial knee joint. Artificial knee joints are crafted using biocompatible and non reactive metal alloys, high-grade plastics or polymers that fit in properly with flexibility and restore the knee function. Knee damage causes severe pain, stiffness, inflammation and movement restriction in daily routine.

A knee injury can be caused from several factors including an accident or trauma, bone degeneration from arthritis or from wear and tear from daily activities and aging. Knee replacement can be performed as a minimally invasive partial or total knee replacement to ease pain, rectify any knee deformity, and to restore the normal activities.  

Among the major reasons for knee damage, osteoarthritis is the main cause for knee damage affecting the knee socket cushion between the knee and the bone joint making it difficult to perform day to day activities. Other conditions associated with knee damage include pain and stiffness, inflammation of joints with limited movement restriction.

Knee replacement procedure

At Kovilpatti Venkateswara Hospital, we provide minimally invasive knee replacement procedure with advantage of faster recovery and healing period. The surgery is performed by preparing the knee bone and removing the damaged cartilages and ligaments next to the underlying bone. Later, an artificial knee implants is placed that recreates the surface of the joint and the undersurface of the kneecap is covered with a plastic knob if needed.  A medically approved high quality plastic spacer is inserted between the artificial knee parts to create a smoothly gliding surface for flexibility.

A knee replacement surgery is classified into four main types as discussed:

  • Total knee replacement: A total knee replacement surgery is recommended for those who have completely damaged knee joint with movement disability and involves replacing the total damaged knee surfaces with an artificial knee implant.
  • Partial knee replacement: Partial knee replacement is performed when only one side of the knee is damaged.
  • Kneecap replacement: Knee cap replacement is performed to replace the under-surface of the kneecap.
  • Complex (or revision) knee replacement: Revision knee replacement is performed in those who have undergone previous knee replacement surgeries.

Patients with early arthritis often benefit from a surgery over upper part of leg, the tibial bone to align the angle so as to off load the joint to reduce the pain.

At Kovilpatti Venkateswara Hospital, we provide the most advanced and sophisticated diagnostics and treatments techniques for patients with knee damage or arthritis to restore the movement and function of knee joints. We brings together a multidisciplinary team of highly qualified and well experienced medical and surgical specialists who offer patients safe and effective treatments and rehabilitative programs to offer the intact continuum of care for the knee arthritis patient. Along with the treatment plan, physiotherapy plans are also provided to ease the pain and for a faster recovery from the surgical procedure. Physiotherapy under a qualified instructor enables faster recovery and management of the artificial implant in the knee joint.  To know more about knee replacement treatment options and treatment cost, book an appointment now.
