Articular Cartilage And Menisci Of The Knee
Movement of the bones causes friction between the articulating surfaces. To reduce this friction, all articulating surfaces involved in movement are covered with a white, shiny, slippery layer called articular cartilage. The articulating surface of the femoral condyles, tibial plateaus and the back of the patella are covered with this cartilage. The cartilage provides a smooth surface that facilitates easy movement.
To further reduce friction between the articulating surfaces of the bones, the knee joint is lined by a synovial membrane which produces a thick clear fluid called synovial fluid. This fluid lubricates and nourishes the cartilage and bones inside the joint capsule.
Within the knee joint, between the femur and tibia, there are two C shaped cartilaginous structures called menisci. Menisci function to provide stability to the knee by spreading the weight of the upper body across the whole surface of the tibial plateau. The menisci help in load- bearing by preventing the weight from concentrating onto a small area, which could damage the articular cartilage. The menisci also act as a cushion between the femur and tibia by absorbing the shock produced by activities such as walking, running and jumping.
What To Do If You Fall After Knee Replacement
If you fall on your knee in the immediate aftermath of surgery, the prosthetic implant may be damaged. If this occurs, revision surgery may be required. Do not walk alone unless you have improved your balance, flexibility, and strength instead, use a cane, crutches, or walker when possible.
An artificial knee joint is used in knee replacement surgery to restore function and alleviate pain. The number of people who have mastitis is expected to reach 3.5 million by 2030. The following exercises and movements should be avoided during your recovery period. When running, the amount of force applied to the knee joint is three times greater than when walking. Consult your doctor before engaging in any contact sports or activities that may cause the knee to twist or jerk suddenly. After surgery, it is critical to remain active in sports such as cycling, golf, and swimming. Most people are back to their original routines within three months of surgery. Fall-prone activities and activities that cause knee twisting are among the most dangerous. When you are unsure if an activity is safe, consult with your doctor.
What Is The Recovery Like After Total Shoulder Replacement Surgery
Most patients are given a morphine pump after surgery so they can control their own pain medicine. After a day or so most patients switch over to pain medicine by mouth. The arm will be in a brace but it can be taken off to do therapy. Antibiotics are given by vein for a day to prevent infection. Physical therapy begins the day after surgery and begins with moving the fingers, wrist and elbow. Some motion of the shoulder is begun within a day or so after surgery. The physical therapist will show the patient a program of exercises to do at home. Most patients stay in the hospital from three to five days.

Types Of Quad Exercises To Do After Knee Replacement
Your leg muscles may feel weak after surgery because you did not use them much with your knee problems. Surgery corrected the knee problem. Your home exercise program will include activities to help reduce swelling and increase your knee motion and strength. This will help you move easier and get back to doing the activities you enjoy. The quadriceps tendon, which is located above the kneecap, is typically cut and sutured back together during surgery. Physical therapy exercises that engage the quad muscles are essential to your healing, recovery, and pain reduction.
Learning To Live With Your New Knee
Having a total knee replacement provides significant pain relief for more than 90 percent of people who have the surgery.
It can take some time to get used to the new knee, so its important to understand what is normal during recovery and how having an artificial knee can affect your day-to-day life after surgery.
Your new knee doesnt come with an owners manual, but recognizing potential issues and preparing for them can help maximize your quality of life after surgery.
Its not unusual for your artificial knee to make some popping, clicking, or clunking sounds, particularly when you bend and extend it. This is most often normal, so you shouldnt be alarmed.
Several factors can affect the likelihood of these noises or sensations after surgery, including the

When Therapy Ends The Recovery Continues
Physical therapy visits will eventually end, but recovery from TKR will continue for several months. Developing an ongoing exercise plan with the physical therapist before that time comes is essential. Also, finding a physical activity that is enjoyable and beneficial is important. A new joint can re-open many activity doors, so pick one and get moving. For more information about recovery from joint replacement surgery, speak with an orthopedic specialist or physical therapist.

Problem: Fixing Pain After Total Knee Replacement May Include Amputation
Three in 1000 patients will need to have their leg amputated.
The causes of the amputation were:
- infection around the implant ,
- soft-tissue deficiency surrounding the implant ,
- severe bone loss ,
- fracture around the implant ,
- circulatory damage .
In 80% of the cases, there were more than 2 of these factors for amputation.
In research from April 2017, doctors writing in the European Journal of Orthopaedic Surgery and Traumatology wrote:
Treatment for prosthetic knee replacement is becoming more common. Infection is an arthroplasty-related complication leading to prolonged hospitalization, multiple surgical procedures, permanent loss of the implant, impaired function, impaired quality of life, and even amputation of the limb.
The purpose of this study was to identify risk factors for amputation in the periprosthetic infected knee through a case-control study, analyzing patients treated from January 2012 to November 2016 in a hospital with a high incidence of this diagnosis. We included 183 patients with periprosthetic knee infection 23 required amputation as definitive management .
They found that patients with:
- Increased surgical time > 120 min,
- diabetes mellitus had an increased risk of amputation.

Muscles Affected By Knee Replacement
There are many muscles that are affected by knee replacement surgery. The quadriceps, hamstrings, and gastrocnemius muscles are all affected. The quadriceps muscle is the primary muscle used for knee extension. The hamstrings are the primary muscles used for knee flexion. The gastrocnemius muscle is responsible for plantar flexion of the foot.
Muscle deficits persist after anterior knee replacement and have implications for rehabilitation, Physical Therapy, Volume 89, Issue 10, 1 October 2009, Pages 1072-1079, https://doi.org/10.2522/ptj.0295. You can close the Navbar Search Filters by clicking the Close Navbar Search button. Because of knee joint arthritis, there is pain, a decrease in motion, and limitations in mobility. Slow stair descent times were expected as a result of a larger deficit in knee extension power. Some participants wore non-operational knee braces and developed osteoarthritis. The mobility of a patient who has recently had knee replacement is expected to be reduced in the first month after the operation. A disability or mobility limitation in the lower limbs should be considered in order to minimize disability and mobility limitations.
What Are The Possible Complications Of Total Shoulder Replacement Surgery
Fortunately the complications rate after surgery is small . Infection is a concern but happens rarely since antibiotics are given to prevent it. Nerve or artery damage is very rare. Since the shoulder is a ball and socket, the ball can shift out of the socket . Again, this is very uncommon. Lastly the components of the replacement can get loose from the bone over time, especially if the arm is used excessively. After ten years approximately 3 percent of the shoulders are loose, but revision surgery is rarely needed.

The Knee Cap Was Floating Because The Mcl Was Released Patellar Maltracking After Total Knee Replacement The Concern Of Catastrophic Laxity
Lets look at two studies surrounding the medial collateral ligament.
The first is from 2015, the second is from 2021
In June 2015 in the journal Knee Surgery, Sports Traumatology, Arthroscopy researchers wrote: Medial collateral ligament release is one of the essential steps toward the achievement of ligament balancing during the total knee arthroplasty in patients with varus deformity . When the varus deformity is severe, complete release of the MCL until balanced is often required. However, it is believed that a complete MCL release may lead to catastrophic laxity.
In March 2021, a study published in the journal Knee Surgery and Related Research continued that Medial collateral ligament release during knee replacement could lead to the surviving knee cap floating around the knee. Here are the studys observations: Patellar maltracking after total knee arthroplasty can lead to significant patellofemoral complications such as anterior knee pain, increased component wear, and a higher risk of component loosening, patellar fracture, and instability. . . A complete release of the MCL during surgery was associated with patellar maltracking. Surgeons should attend to patellar tracking during surgery in medially tight knees.
What Are Possible Side Effects Of The Surgery
Urquhart: All surgeries have a risk of complications. Less than 1% of healthy patients undergoing any type of surgery can experience a cardiovascular event, such as a heart attack or stroke. About 0.5% of knee replacement surgery patients develop an infection.
But an important side effect or outcome to talk about is this buyers remorse idea I brought up earlier. About 15 to 20% of patients that undergo total knee replacement surgery have buyers remorse because they still experience discomfort, clicking or a sensation of instability in their knee, making them regret having the procedure. That is exactly why we consider non-surgical options first and remind patients that they should not make the decision to have surgery without careful consideration.

Is It The Opioids
A 2019 paper from Brigham and Womens Hospital, Harvard Medical School, Boston describes the problems of opioid use before knee replacement.
Prescription opioid use is common among patients with moderate to severe knee osteoarthritis before undergoing total knee replacement. Preoperative opioid use may be associated with worse clinical and safety outcomes after total knee replacement.
In this study, the researchers targeted preoperative opioid use among patients 65 years and older with mortality and other complications at 30 days post-total knee replacement.
Study learning points:
- 316,593 patients who underwent total knee replacement:
- 22,895 were continuous opioid users before surgery.
- 161,511 were intermittent opioid users before surgery.
- 132,187 did not use opioids before surgery.
What Kind Of Knee Injuries Can Cause Severity
If the weather is cold, and your knees are not in perfect health , it can cause the following type of issues:
Knee Trauma: Cold season can affect the muscles that hold your knee joint. The surrounding muscles play an important role in supporting the joint from all sides. When these tissues are warm, they work and move with less effort.
In colder months, they have to work much harder to do the same tasks. The extra energy makes them tired and causes tissue mutilation. Hence, the patient experiences more agony compared to the summers.
Patellar Tendonitis: This condition is also called the jumpers knee in laymans language. It causes pain while climbing stairs or jumping.
Winters induce stiffness in the tendons and a decrease in circulation, thereby aggravating the injury. The ache spreads below the knee caps.
Runners Knee: This is directly related to an overuse of the joints. It is often experienced by sports persons or active joggers.
The rubbing of the kneecap against the thighs causes the running knee condition. The result is cartilage wear and tears. As the weather becomes cold, it makes the surrounding muscles of these joints stiffer, hence triggering the pain.

How Long Will I Be On Pain Medication After My Knee Replacement Surgery
Every patient experiences recovery from a knee replacement surgery differentially and as such, everyone will require pain medication at different intervals and for different amounts of time. There is no standard approach to this, although generally we do expect patients to be weaned off their narcotic analgesics within 2 to 3 weeks of the surgery and by 6 weeks after the surgery should only be requiring occasional Tylenol or a less potent analgesic to control their pain.
With that being said, there are a number of different factors that can affect a persons ability to tolerate pain medication or indeed their ability to have the pain medication kill their pain. As such, each medication regimen will be tailored to the individual. It is important to regularly communicate with your surgeon or healthcare provider regarding your experience of the pain and your current pain medication regimen, so that it can be altered to suit you and your needs.
Indications For Muscle Sparing Total Knee Replacement
Muscle sparing total knee replacement surgery is commonly indicated for severe osteoarthritis of the knee. Osteoarthritis is the most common form of knee arthritis in which the joint cartilage gradually wears away. It often affects older people.
In a normal joint, articular cartilage allows for smooth movement within the joint, whereas in an arthritic knee the cartilage itself becomes thinner or completely absent. In addition, the bones become thicker around the edges of the joint and may form bony spurs. All of these factors can cause pain and restricted range of motion in the joint.
Your doctor may advise muscle sparing total knee replacement if you have:
- Severe knee pain that limits your daily activities .
- Chronic knee inflammation and swelling
- Knee deformity with loss of cartilage and pain
- Injury or fracture of the knee
- Instability of the knee
- Moderate to severe pain that occurs during rest or awakens you at night
- Failure of the non-surgical treatment options such as medications, injections and physical therapy to relieve symptoms

Muscles Are Around The Knee
The main knee muscle groups are the:
- Quadriceps: four muscles found on the front of the thigh
- Hamstrings: three muscles found on the back of the thigh
- Calves: two muscles found on the back of the lower leg
- Glutes: three muscles that make up the buttocks
- Popliteus: small muscle found at the back of the knee
Let’s have a look at each of the muscles around the knee, how they work, what activities they are important for, how they are injured and how to target them.
Catastrophizing Thoughts And Central Sensitization = Catastrophic Results And Opioid Dependence After Knee Replacement
Researchers in Canada writing in the Journal of Pain Research found pain catastrophizing reflects a patients anxious preoccupation with pain, inability to inhibit pain-related fears, amplification of the significance of pain, and a sense of helplessness regarding pain.
Catastrophizing thoughts are unrealistic beliefs that only the worst can happen. A person who goes into any medical treatment believing it will not work is at a significant disadvantage. A patient should relay these thoughts to his/her doctor so that appropriate action can be taken. For some patients, counseling will be effective, for some therapy, for some prayer. The patients must be made aware of options that will help them move from hopelessness to cautious optimism.
A significant problem with catastrophizing thoughts that needs to be addressed is a greater risk for opioid dependence.
Doctors in Belgium write in the Bone and Joint Journal that pre-operative pain in the knee predisposes to central sensitization . Pain due to osteoarthritis of the knee may also trigger neuropathic pain and may be associated with chronic medication like opioids, leading to a state of nociceptive sensitization called opioid-induced hyperalgesiapainkillers increase chronic pain.

Patients May Need Subsequent Surgeries To Maximize The Benefits Of Joint Replacement
Many patients with hip and knee arthritis have the condition in more than one of their hip or knee joints, said the studys lead author Dr. Gillian Hawker. So its not surprising that replacing a single joint doesnt alleviate all their pain and disability patients may need subsequent surgeries to maximize the benefits of joint replacement.
The study, published in the journal Arthritis & Rheumatism , followed a group of patients with osteoarthritis and inflammatory arthritis. Only half reported a meaningful improvement in their overall hip and knee pain and disability one to two years after surgery. Whats more, researchers found the patients who had the worse knee or hip pain to begin with but fewer general health problems and no arthritis outside of the replaced joint were more likely to report benefits.
According to the study authors, nearly 83 percent of study participants had at least two troublesome hips and or knees.
- In general, an estimated 25 percent of patients who undergo a single joint replacement will have another joint replacement usually the other hip or knee within two years.
Why Physical Therapy Failed Post
A February 2022 paper in the Journal of evaluation in clinical practice comes to us from the Physical Therapy Program, Department of Physical Medicine and Rehabilitation, University of Colorado.
In this survey of patients and physical therapists describing the patient experience and expectation of physical therapy following total knee replacement, the therapists found that in many cases patients were not given a true indication of the amount of therapy that would be required post-knee surgery and that further, many patients were given little of no information of how to proceed in the post-recovery period from their surgical team, specifically as their treatment related to physical therapy. Many patients in fact were not part of the shared decision making processes.
The information that emerged in this survey was:
- A lack of standardized approach for involving patients in their rehabilitation decisions. This could impact patient motivation as the study notes patient decision making could be a key component of rehabilitation success and a key ingredient in promoting patient engagement. In other words, talk with your physical therapists or nay health care provider about your goals of treatment.
