Deciding between partial and total knee replacement is an important step on your journey to better mobility and reduced pain. At Manchester Hip Knee Surgeon, we tailor every treatment plan to your unique needs, ensuring you receive the most appropriate procedure. This article explores the differences, benefits, and candidacy criteria for both partial knee replacement (PKR) and total knee replacement (TKR).
Understanding the Procedures
Partial Knee Replacement (PKR)
- Scope: PKR replaces only the damaged compartment of the knee—most commonly the medial (inner) or lateral (outer) side—leaving the healthy portions intact.
- Technique: Performed through a small incision, a specialised implant replaces the worn cartilage surface.
- Recovery: Generally faster recovery, less postoperative pain, and smaller scar compared with TKR.
Total Knee Replacement (TKR)
- Scope: TKR involves resurfacing the entire knee joint, replacing the femoral, tibial, and sometimes patellar surfaces with prosthetic components.
- Technique: Requires slightly larger incision to accommodate full joint replacement.
- Recovery: Standardised rehabilitation protocols; excellent long-term durability for extensive arthritis.
Who is a Good Candidate?
Ideal PKR Candidates
- Isolated Compartment Arthritis: Damage confined to one compartment, with healthy cartilage elsewhere.
- Stable Ligaments: Intact cruciate and collateral ligaments to provide joint stability.
- Moderate Deformity: Mild angular deformities (often less than 10–15 degrees).
- Active Lifestyle: Patients seeking rapid recovery and a more ‘natural’ knee feel.
Ideal TKR Candidates
- Widespread Arthritis: Arthritis affecting multiple compartments of the knee.
- Severe Pain & Stiffness: Significant loss of function and chronic pain unresponsive to conservative measures.
- Ligament Laxity or Deformity: More advanced deformities or ligament imbalance.
- Long-Term Reliability: Patients prioritising durability and comprehensive correction.

Recovery & Rehabilitation
PKR Rehab Highlights
- Day 1 Mobilisation: Many patients begin walking with aids on the day of surgery.
- Physiotherapy Focus: Range of motion, quadriceps activation, and balance.
- Return to Activity: Light activities within weeks; most resume normal walking and non-impact sports by 6–8 weeks.
TKR Rehab Highlights
- Postoperative Day 1: Physiotherapy begins immediately to prevent stiffness.
- Structured Programme: Progressive exercises to restore full extension and flexion.
- Timeline: Most patients achieve functional independence by 8–12 weeks, with continued strength gains up to 6 months.
