Is It Worth Delaying Total Knee Replacement as Late as Possible? A Cost-Effectiveness Analysis

TKR cost

In today’s era of advanced medical science, total knee replacement (TKR) surgery has emerged as a successful surgical option for patients with severe knee osteoarthritis. Despite the relatively high TKR cost, most prostheses have a life-span of around 20 years. 

The TKR cost is frequently postponed in young individuals to increase prosthesis duration and decrease the chance of needing another surgery. However, postponing TKR could harm the overall standard of living for young individuals who are usually physically fit and healthy. It’s important to consider the long-term implications and discuss the decision with a healthcare professional to ensure the best outcome.

In this article, you’ll learn what methods researchers have used to determine whether delaying TKR as late as possible is a cost-effective decision.  

Methods | Insight From Researchers on Delayed TKR Surgery

Researchers created a Markov decision model to examine the hypothetical clinical progression of a 50-year-old individual with acute unilateral knee osteoarthritis who might one day receive either conservative treatments or a TKR. 

Longevity costs (in Indian rupees), quality-adjusted life years (QALYs), and the ICER or incremental cost-effectiveness ratio were computed using a model from the perspective of an Indian. 

Overview of The Research On Delayed TKR Surgery

In a new study, the economic feasibility of postponing TKR in someone with acute unilateral knee osteoarthritis was evaluated using a Markov decision model. 

The research also indicated that delaying TKR as much as possible reduces the overall percentage of QALYs patients would have encountered over their lifespan. 

With every additional year of postponement, the incremental cost-effectiveness (ICER) ratio for postponing TKR rose. According to the research’s outcomes, postponing TKR in individuals with advanced osteoarthritis might not be a wise financial decision. 

Postponing the TKR can potentially reduce the likelihood of revision, but it also lowers the overall standard of living and increases ICER.

Research Findings | Is Delaying TKR Worthwhile?

The researchers concluded that TKR cost is a financially advantageous surgery when a medical payer is prepared to shell out a minimum of $132 (INR 9789) for each QALY. 

Given the higher rate of revisions, the data also revealed that a premature TKR is favoured over a delayed one. However, you must not generalise the research outcomes to all those suffering from chronic osteoarthritis because they depend upon a particular patient group. 

Determining whether to postpone TKR must be done on an individual basis, taking the patient’s desires and unique circumstances into consideration.

Considering Postponing TKR? Here’s What To Remember

According to the research’s outcomes, TKR is a reasonably priced treatment for chronic knee pain and impairment. Nevertheless, it’s crucial to thoroughly consider the expenses and advantages of surgery and evaluate the pros and cons with your surgeon. 

Consider these additional factors while choosing whether to postpone TKR or not:

  • Activity Level: You might wish to think about TKR as soon as possible if you’ve been exercising and intend to stay active.
  • Age: The likelihood of requiring revision surgery increases with age.
  • Overall Well-Being: You may be more vulnerable to TKR consequences if you suffer from other medical conditions like diabetes or cardiovascular disease.

The choice to postpone TKR is essentially a personal one. Do what best fits your needs by discussing your explicit condition with your doctor.  

Benefits of Total Knee Replacement Surgery 

The objectives and potential advantages are the same for minimally invasive partial knee replacements (mini knee) and standard total knee replacements: pain reduction and functional rehabilitation.

After recovering from a total knee replacement, most (more than 90%) patients report feeling significantly or completely pain-free. Most people don’t need a cane, regardless of whether they did before surgery, and most walk without a limp.

The operation often also reduces arthritis-related stiffness. A person’s ability to walk farther will also frequently increase, thanks to lesser discomfort and soreness. 

Following a complete knee replacement, the pleasure of moderate pastimes like golf, exercising, adventuring, and diving almost invariably increases.

Key Takeaways

A safe surgical procedure called total knee replacement replaces the uncomfortable arthritic portions of the knee joint with prosthetics. Over 90 percent of the individuals who undergo surgery report significant reductions in pain and an improvement in mobility. 

Total knee surgery has dangers, just like any other significant procedure. Therefore, knee replacement should be viewed as a quality-of-life decision each patient makes after thoroughly knowing the hazards.
