Prevalence
TKR is one of the most commonly performed orthopedic surgeries worldwide, especially among older adults. In India, the number of TKR procedures is rapidly increasing due to rising cases of osteoarthritis.
Occurrence
It is most frequently performed on individuals above the age of 50, particularly those with severe knee arthritis or joint deformity that hasn’t responded to conservative treatments.
Affected Male-Female Ratio
Women are more commonly affected than men. Studies indicate the ratio can range from 1.5:1 to 2:1, likely due to higher prevalence of osteoporosis and arthritis in females.
Causes of Total Knee Replacement (TKR)
| S. No. | Cause | Description | Common Age Group |
|---|---|---|---|
| 1 | Osteoarthritis | Age-related wear and tear of knee cartilage leading to joint damage. | 50+ years |
| 2 | Rheumatoid Arthritis | Autoimmune disease causing joint inflammation and cartilage erosion. | Any age (common in 30–60) |
| 3 | Post-Traumatic Arthritis | Arthritis following knee injury (fracture, ligament tear, etc.). | Any age, post-injury |
| 4 | Knee Deformities | Abnormal knee alignment like bow legs or knock knees causing chronic stress. | Varies (often 40+ years) |
| 5 | Avascular Necrosis | Loss of blood supply to knee bones leading to bone death. | 30–60 years |
| 6 | Failed Previous Surgery | Previous knee surgeries that failed to relieve pain or maintain function. | Typically 50+ years |
| 7 | Congenital Conditions | Structural abnormalities present from birth leading to joint damage over time. | Early onset, varies |
Role of Physiotherapy
Physiotherapy is crucial for successful recovery post-TKR. It focuses on:
- Reducing pain and swelling
- Regaining knee movement
- Improving muscle strength
- Restoring walking ability and balance
- Ergonomic correction
- Supporting return to daily activities safely
Take Away
Early and consistent physiotherapy leads to faster recovery, better function, and long-term joint health after knee replacement. It’s as important as the surgery itself.
If Neglected, Then Complications
Without proper rehab, patients may face:
- Stiffness and restricted knee movement
- Poor walking patterns
- Muscle weakness
- Increased risk of falls and re-injury
- Failure to return to independent lifestyle
When to Seek Help
Seek physiotherapy help:
- Within 24-48 hours post-surgery (in hospital)
- If you have difficulty walking, bending, or climbing stairs after surgery
- In case of prolonged pain, swelling, or fear of movement
Remember: Rehabilitation is not just recovery—it’s your pathway to a new, pain-free life. Trust the process, follow your physiotherapist’s guidance, and step confidently into mobility!
