What does knee replacement surgery entail?

Are you tired of feeling like an old creaky door every time you walk? Do your knees make noises that scare small children and animals alike? Fear not, for knee replacement surgery is here to save the day! In this article, we will be exploring what exactly knee replacement surgery entails.

What is Knee Replacement Surgery?

Knee replacement surgery, also known as arthroplasty, is a surgical procedure that involves removing damaged or diseased parts of the knee joint and replacing them with artificial components made from metal alloys, high-grade plastics or polymers. It’s a common treatment option for people suffering from severe osteoarthritis or other conditions that cause chronic pain and disability in their knees.

Pre-Operation Procedures

Before undergoing knee replacement surgery, there are several steps both you and your doctor must take. First off, your doctor will perform a thorough physical examination of your knee joint to determine the extent of damage caused by underlying conditions such as arthritis.

Next up on pre-op procedures comes medical history evaluation where it would be identified if any medications such as blood-thinners may need to be discontinued prior to surgery. You will also undergo various diagnostic tests including X-rays and MRI scans which provide detailed images of bone structure around the affected area highlighting bits such as muscle imbalances around the joint; all these play crucial roles in determining how much artificial apparatus needs inserting into joints.

The next step involving lab work/analysis might require drawing off some blood samples:

Types Of Knee Replacements Procedures

There are two main types: Total Knee Replacement (TKR), also called Total Knee Arthroplasty (TKA), and Partial Knee Replacement. More commonly performed, TKA involves replacing the entire knee joint with prosthetics that take over its vital functions; this makes it perfect for treating severe arthritis or extreme damage cases.

Partial Knee Replacement allows a surgeon to replace one side of the knee joint affected by arthritis with an artificial inlay avoiding tissue strain and improving mobility without fully ‘knee-gearing’ patients compared to TKR which demands rehab post-surgery physiotherapy sessions.

Surgery Process

Once you have been checked into the hospital, your anaesthesiologist will administer anaesthesia and commence sedation (relaxing like a king on propofol). The surgery itself usually takes 1-2 hours depending on how much apparatus has to be implanted during which time a range of different surgical devices is used such as bone-cutters, drills & saws before finally sapping skin suturing sustenance by means of stitching at strategic points along incision sites.

Collaborative teamwork ensures constant cerebral function monitoring throughout operation anchored around steady hands manipulating delicate high-quality instruments specially designed for successful completion in minimally invasive ways leaving behind barely noticeable scars after recovery period

Postoperative Care And Rehabilitation

Post-op care and rehabilitation are crucial parts of your recovery process. After surgery, you will spend several days recovering in the hospital where healthcare professionals monitor symptoms while ensuring effective pain management therapies are administered so pain sticks no leg.

Pain management techniques may include receiving icing therapy via ice packs placed against swollen tissues soaked up using elastic bandages to reduce muscular inflammation within treated areas assuaging localised nerve responses caused by exertion-related conditions like great tension build-up injuries or septic shock reactions triggered due some allergic experiences originating from sensitivity issues involving body interacting chemically plus other therapeutic procedures added expeditiously towards optimal recuperation times ongoingly tailored down patient’s specific needs predicated upon medical advice from professional caregivers attending to patients.

Note: Recovery time following Knee Replacement Surgery can differ from individual due to age or prior health conditions. It’s important that you listen attentively and obey guidelines of your physician or therapist to avoid complications

Risks Associated with Knee Replacement

As with any surgical procedure, knee replacement surgery comes with certain risks, which may include but are not limited to:

  • Infection
  • Nerve damage
  • Allergic reactions
  • Blood vessel injury
  • Implant failure
  • Blood clots

To reduce the likelihood of developing these types of postoperative complications related directly or indirectly towards operative procedures an all-encompassing pre-admission ‘best practices’ checklist is given out before admission outlining things that need special attention by both doctors/nurses taking care of patients in lead up times programmed for minimising unnecessary harm.


Knee replacement surgery has come a long way over the years, and it’s now one of the most common surgeries performed worldwide (thankfully no more walking like Frankenstein on streets during weekdays) . Although there are still some associated risks involved, modern technology and advancements in joint-replacement techniques have helped mitigate such issues thereby reducing recovery period after surgery ensuring efficient pain-free mobility than ever before!
