Lecture 5-Arthritis and Joint replacement knee

Knee Replacement DetailsKnee replacement surgery is performed to relieve pain and restore function in patients suffering from severe knee arthritis. Each type of knee replacement has distinct features and rehabilitation implications.

Replacement Types

• Unicompartmental (Partial) Knee Replacement:

  • Replaces only the damaged part of the knee joint.

  • Suitable for patients with arthritis confined to one compartment.

  • Generally shorter recovery time than total knee replacement.

• Total Knee Replacement (TKR):

  • Replaces the entire knee joint including femur, tibia, and patella.

  • Recommended for extensive damage and arthritis.

  • Longer recovery and more intensive rehabilitation compared to unicompartmental replacement.

Implications for Rehabilitation

The type of surgery impacts rehabilitation protocol:

• Unicompartmental:

  • Focus on restoring range of motion and strength quickly due to less tissue disruption.

• Total Knee Replacement:

  • Takes a more gradual approach emphasizing mobility and strength over several weeks to months.

  • Regular follow-ups are necessary to monitor progress.

General Rehabilitation Approach for Knee Replacement

• Week 1:

  • Focus on functional activities like sitting and standing, along with initial range of motion exercises.

• Weeks 2-6:

  • Progress to strengthening exercises for quadriceps and hamstrings; also include balance and stability activities.

Considerations in Rehabilitation

Patients must understand pain management and the importance of sticking to rehab programs. Avoid high-impact activities and ensure proper exercise techniques to optimize recovery. Initially, tools like braces or walkers may be advised to assist with mobility. Effective communication among the patient, surgeon, and rehab team is crucial for successful post-surgery outcomes.
