Arthroscopy Knee

Patients with certain types of meniscal tears and cartilage damage are prime candidates for the minimally invasive surgical intervention called Arthroscopy Knee diseased by osteoarthritis, rheumatoid or psoriatic arthritis can also be treated using arthroscopy.

The following covers the different types of treatments for meniscal tears and cartilage damage with a partial focus on arthroscopy assisted procedures.

Meniscal Tears

The most common non-surgical treatments of meniscal tears are:

• Rest, Ice, Compression, Elevation, (RICE)
• Non-Steroidal anti-inflammatory medicines

The outer third of the meniscus has a healthy supply of blood so can heal successfully without the trimming of smaller tears using arthroscopy. Though the inner two thirds of meniscus plates have a much reduced blood supply meaning tears in the region are more likely to require arthroscopic intervention.

For surgical treatment of meniscal tears there is:

• Arthroscopy: a miniature camera is inserted through a small incision to provide a view of the inside of the knee. Miniature surgical instruments are then inserted in separate incisions to trim or repair the tear.

Cartilage damage

As cartilage does not heal easily of its own accord, surgical techniques have been developed to assist cartilage regrowth. Cartilage restoration can relieve pain and delay the onset of arthritis. Arthroscopy has many different applications in treating cartilage damage, such as:

• Microfracture: A small pointed tool called an awl is used to create small holes in the subchondral bone. This stimulates new blood supply and cell growth in the cartilage.

• Drilling: stimulates the production of healthy cartilage. Multiple holes are made in the subchondral bone using drills or wires to initiate a healing response. Though the tools used are less precise than microfracture. Arthroscopy.

• Abrasion Arthroplasty: instead of using drills or wires, high-speed burrs remove the damaged cartilage and reach the subchondral bone. Arthroscopy.

• Autologous Chondrocyte Implantation: using arthroscopy of the knee this procedure extracts healthy cartilage tissue, then grows the cells in a laboratory over 4-5 weeks. Using open knee surgery, the cells are the re-implanted in the site of the damaged cartilage. Arthroscopy and arthrotomy, (open surgery).

• Osteochondral Autograft Transplantation: healthy cartilage is lifted using a cylindrical plug from a non-weight-bearing area of the knee joint, then transferred to the defective area and pressed into place. A single plug or multiple plugs can be used. Arthroscopy and open surgery.

• Osteochondral Allograft Transplantation: when the defect is larger, instead of autografts, allografts use tissue grafts taken from cadaver donors. Allografts usually use open knee surgery.

Orthopaedic Surgeon brief on sub-specialties depending on the region of the body

Orthopaedics is a branch of medical surgery and therapy that treats injuries and diseases of the body’s skeletal system. This includes the bones, joints, muscles, ligaments and tendons. This vast system that enables the uprightness and movement of the human frame is called the musculoskeletal system.

When first practiced orthopaedics treated children with spinal, leg or arm deformities. Though orthopaedic surgeons now help patients of all ages and for a range of different conditions.

Within orthopaedics there are many different sub-specialties depending on the region of the body they treat. Orthopaedic surgeons can specialise in:

Hand surgery

Hand surgery treats a range of conditions from cuts, burns, crushing injuries or diseases of the hand. Some common conditions are congenital deformities; repetitive stress injuries, like carpal tunnel syndrome; arthritis; and tendon repair. The priority for orthopaedic surgeons is to adequately reconstruct the skin, bone, nerves, tendons and joints. This is to protect the anatomy of the hand for recovery of functionality and aid the healing process by limiting the chance of infection. Early intervention is very beneficial.

Shoulder and elbow

The shoulder is a complex and unstable joint which can get injured easily. The elbow is vulnerable to deterioration from age or injury related conditions as well. The orthopaedic surgeon has many means of treating the muscles, connective tissue, or damaged joints that come from the overuse or injury of the shoulder or elbow. Some common procedures are arthroscopy or arthroplasty.

Arthroscopy is a form of keyhole surgery that magnifies and creates a visualisation of the interior of the body around the joint being operated on. While arthroplasty is the surgical removal and replacement of a joint or a section of the joint.

Hip and Knee

The hips and knees are the largest joints in the body. They are designed to work in close coordination to provide the mobility most people take for granted. The hip is a large ball and socket joint susceptible to both injury and disease. Some of the most common forms of hip disease are:

• Osteoarthritis
• Rheumatoid arthritis
• Post-traumatic arthritis
• Avascular necrosis

As with the shoulder and elbow, both the knee and the hip can be successfully treated by either arthroscopy or arthroplasty. Hip and knee replacement are two of the most common and successful procedures available to patients.

Pediatric orthopaedics

The pediatric orthopaedic surgeon specialises in children’s musculoskeletal problems. As children are still growing, the body's response to injuries, infections, and deformities can be quite different from the recovery of adults. Some of the conditions particular to this specialty are:

• Limb and spine deformities, (clubfoot, scoliosis, limb length differences)
• Gait abnormalities (limping)
• Broken bones
• Bone or joint infections and tumors

Foot and Ankle surgery

The treatment of the the foot and ankle is a sub-specialty of both orthopaedics and podiatry. The surgeon treats conditions that range from:

• Trauma: such as fractures to the malleolar, tibial pilon, calcaneus, navicular, metatarsal, phalangeal

• Arthritis: joints of the tarsals, metatarsals and phalanges, etc.

• Congenital and acquired deformities: flatfoot, non-neuromuscular foot deformity, diabetic foot disorders, hallux valgus and several common pediatric foot and ankle conditions.

Spine Surgery

The are many potential causes for the need for spinal surgery. There is aging, improper body mechanics, trauma and structural abnormalities. These conditions can lead to back pain and symptoms such as leg pain and/or numbness or leg weakness. The most common procedures conducted are:

• Discectomy or Micro-discectomy: removal of a herniated intervertebral disc.
• Laminectomy: removal of the thin bony plate on the back of the vertebra called the laminae.
• Laminotomy: removal of a portion of the vertebral arch, (lamina), that covers the spinal cord.
• Foraminotomy: removal of bone or tissue at/in the passageway where nerve roots branch off the spinal cord.
• Disc replacement: the injured disc is replaced with an artificial one.
• Spinal fusion: technique used to join two vertebrae.

The three sub-specialties of orthopaedics not based on the body region where they occur are:

• Musculoskeletal oncology, (cancer treatment)
• Surgical sports medicine, (activity based injury)
• Orthopaedic trauma, (accident based injury)

Hip Replacement Recovery

In large part, the pace and quality of your recovery post a total hip replacement is down to how well you follow the advice given by your surgeon. The first weeks after an operation are crucial to the success of your recovery and the advice you are given should be followed.

Sometimes feeling well can put you in a state of mind where you are less likely to be cautious. This can lead to unnecessary accidents and setbacks, but equally, being too cautious can limit the return of your flexibility and your capacity for activity overall. Provided you are not taking risks the exercises should be done routinely even if you are feeling a little unwell.

There are many aspects to your homecare regimen. The first concern of hip replacement recovery is taking care of the healing process of the incision site. Usually, at around two weeks the stitches or staples will be removed. During this first fortnight, it is very important to keep the area dry at all times. Special waterproof patches can be bought, partners or relatives can help, or you can organise general homecare assistance.

Some people overlook that during their hip replacement recovery they might experience a loss of appetite. This reaction can last several weeks into the recovery process and if not countered can contribute to poorer recovery rates. The main reason is that a good diet promotes the healing process and will restore muscle strength. Often the loss of muscle strength is a contributing factor to any unwillingness to perform the necessary exercises crucial to regaining mobility. Iron supplements are also recommended.

The exercises you are assigned to do during your hip replacement recovery are particularly important. For the first few weeks post surgery, the care and regularity of your exercises will contribute to its overall success.

Normally, patients will have a customised exercise routine recommended by their doctor, but some of the more common exercises are:

• A graduated walking program to slowly increase mobility

• Slowly taking on normal household activities; like sitting, standing, and climbing stairs

• Tailored exercises several times a day.

These exercises restore movement and strengthen your hip. A lot of people opt for the services of a physical therapist. They can assist you at home for the first few weeks after surgery, or there is also the option of choosing the services of a therapy center instead. In fact, the role of rehabilitation centers in a patients hip replacement recovery can be instrumental, in the rate of recovery and the patients proper understanding of the ‘do’s and don’ts’ of the recovery process.

The standard resumption of light daily duties usually takes anywhere in between 3-6 weeks, with the possibility of discomfort during activity and at night.

Total Hip Replacement

Total Hip Replacement is an operation to remove the acetabulum and femoral head of the hip joint to implant a ball and socket prosthesis to function as a moveable joint as a replacement. Total Hip Replacement is called Arthroplasty.

In a well-functioning hip joint both the acetabulum and the femoral head are lined with surface cartilage, or what is called articular cartilage. This surface layer of cartilage is encapsulated by synovial fluid which acts as a lubricant to assist joint movement. The cartilage acts as a shock absorber and smoothens the roll of the joint and under normal circumstances lasts a lifetime.

When the depletion of cartilage exposes bone to friction, chemical reactions and inflammation occur to degenerate the condition of the cartilage further. The mechanical wear caused by bone on bone friction is the primary condition of osteoarthritis and the source of the associated swelling and pain. 

The prosthesis used in Total Hip Replacement comes in two sections. The upper thighbone, (femoral head), implant is generally made of a metal or ceramic ball attached to a splint inserted into the top of the bone. The socket half of the implant is made of ceramic or a special plastic called polyethylene. Due to the acetabulum being concaved the implant is surrounded by bone surface to adhere to.

As to how the implants are affixed, two standard types of total replacement methods exist. There is the cemented method and the cement-less. The cement used to affix implants to bone is called methyl methacrylate. The cement-less method however uses microscopically porous materials to allow the bone to grow into and adhere to the implant.   

Understanding Total Hip Replacement Surgery

A procedure in which the damaged or broken hip parts or areas are replaced with synthetic and artificial materials with durable and smooth substance to help make joints work properly is called hip replacement. To know what type of surgery is needed, the person that will undergo replacement should be examined by orthopedic surgeon. Nowadays, one of the most effective solutions to recuperate damaged hip due to arthritis or injury is hip replacement surgery.

Understanding Partial and Total Hip Replacement

Understanding hip replacement is important to be able to prepare for the surgery. First, we need to understand the difference between partial and total hip replacement. Now, both partial and total replacement will need a replacement in certain or all areas of the hip. In partial hip replacement, only half of the hip joint needs replacement. This occurs once the ball of the femur gets worn-out hence limiting movement and motion of the leg and creating ache and discomfort while walking. Total hip replacement, however, uses a synthetic joint in order to replace whole damaged hip framework. The process is similar to the partial replacement surgery, just this point the socket is replaced as well with synthetic. 

Some Preparations You Can Do Before Undergoing Hip Replacement Surgery

Oftentimes, when you have made a decision to go for hip replacement surgery, you’ll be given a full physical examination by the GP to make sure you are generally in good health and sufficient to undergo the surgery and find out regardless of whether you have conditions or problems which may affect the procedure or even your healing. Other tests you need to go through like a chest x-ray, cardiogram, and urine and blood samples. If you are taking any medicine, it is important that you let your GP know about this so that they can give you advice prior to the surgery.

It's good to donate blood prior to surgery.  You may need blood while in or following the surgery. Moreover, overweight may increase risks of surgery and will put more force on your artificial joint which could affect to your recovery. Have a dental check-up prior to the surgery. Even regular teeth’s cleaning isn’t recommended for a few months following the surgery. Finally, your skin must not have problems or bacterial infections when you go through surgery. Consult your GP to get a treatment if you are experiencing any of these.

In conclusion, it is important to understand what the hip replacement surgery can affect you. Hip replacement surgery won't allow you to perform greater than was doable before. After the surgery, it is strongly recommended that you refrain from certain actions and high-impact sports such as jogging, basketball or cycling. You should also need to avoid particular posture of hip joint that could result in dislocation.

Hip replacement surgery has become an excellent and efficient treatment to repair hip injury. It is important to consider your alternatives by consulting with your GP so that you could be sure if this procedure suits your current condition.

Knee Surgery: A Solution To Avoid Knee Arthritis

Painful knees are a common problem in middle-aged people and elders, and the most common cause of knee pain in this population is Knee Arthritis. There are few treatments for knee arthritis early can help alleviate pain and return people to their daily activities. As some point, arthritis of the knee begins to interfere with the quality of life to the point that something has to change. When treatments such as Anti-inflammatory medications, cortisone injections and physical therapy, do not improve the situation total knee replacement may be an option. The most general reason of chronic knee pain and disability is arthritis. Osteoarthritis, rheumatoid arthritis and traumatic arthritis are the most common. Osteoarthritis generally occurs after age 50 and often in an individual with a family history of arthritis. The cartilage that cushions the bones of the knee softens and wears away. The bones rub together, causing pain and stiffness in the knee. Rheumatoid arthritis is a disease in which the synovial membrane becomes thickened and inflamed, producing too much synovial fluid over-fills the joint space. This chronic inflammation can damage cartilage and eventually cause cartilage loss, pain and stiffness. Traumatic arthritis can follow a serious knee injury. A knee fracture or severe tears in the ligaments of the knee can damage the articular cartilage over time, causing knee pain and limited function of the knee.

Recent Advances in Knee Joint Replacement Surgery: Minimally invasive surgery (MIS) has developed knee replacement surgery, and many fields of medicine. Its key feature is that it uses specific methods and instrumentation to let surgeons to execute major surgery without any large cut. MIS requires a much smaller incision, three inches to five years, compared to standard approach and the incision, which is usually eight to twelve inches. The smaller, less invasive approaches result in less tissue trauma, allowing the surgeon to work between the quadriceps muscle fibers rather than requiring an incision through the tendon. It may lead to less pain, shorter recovery time and better motion due to reduced formation of scar tissue. When a full knee surgery is performed, the bone and cartilage at the end of the thighbone (femur) and upper shin bone (tibia) are removed. This is done with accuracy to craft accurate surfaces to accommodate the implant. A metal and plastic implant knee replacement is put to work as a new knee joint. Depending on the condition of the cartilage on the undersurface of the kneecap, this may also be replaced.

The knee prosthesis implants can wear out over time. The implant is made of metal and plastic, and while these implants are designed to last many years, all of which take time. Studies have shown knee replacement implants are functioning well in 90-95% of patients between 10 and 15 years after the knee surgery. Most full knee replacements last 20 years and many of them last longer. However, it is important to understand that there are possible complications of knee replacement surgery may reduce the life of the implant. Because of this, total knee replacement should be reserved for elderly patients with significant symptoms of arthritis.

When to Consider Hip Replacement Surgery?

If you suffer from osteoarthritis, rheumatoid or septic arthritis, or you have Paget's disease or hip dysplasia, you may experience significant hip pain and reduced movement, which is often significant enough to affect your day-to-day life. While non-surgical treatments, such as medications, physiotherapy and lifestyle changes, are available and can offer some success, these are not always sufficiently effective to relieve pain and improve your functional ability. In these instances, a hip replacement also termed a hip arthroplasty is usually recommended to restore your mobility and quality of life. With a variety of centers in the capital offering surgery to replace a damaged hip joint with an artificial prosthesis, it is important that you do your research before choosing a clinic for your surgery. Choosing a surgeon with expertise in hip arthroplasty makes sure that you will receive the best possible result from your joint replacement surgery so that your expectations of treatment are fully met.

Most doctors have more than 20 years of experience in performing surgical hip replacements. As they keep abreast of developments within the field of orthopedics, they work with the most up-to-date techniques and prostheses, all of which are backed by evidence from clinical studies to guarantee their effectiveness. Besides their commitment to the latest advances in hip arthroplasty, He or She also makes sure he delivers patient-centered care. This means that he involves you in decision-making and tailors your treatment to your individual needs. With his level of expertise and commitment to best practice you can trust that you will receive a complete hip replacement recovery.

Surgery Options:

Before you have your surgery you will meet with an orthopaedic surgeon for an initial assessment. This not only allows him to check your suitability for a hip replacement, but also enables him to advice on the most appropriate prosthesis for your circumstances. In cases where your hip damage is not sufficiently advanced to justify surgery, he will discuss more conservative treatment options with you and may suggest hip resurfacing as an alternative. Certain health problems are sometimes a contraindication to joint replacement surgery, surgeon will also review your medical history before making a decision. When it comes to the type of procedure he recommends, a complete clinical assessment to decide whether a partial or total hip replacement is more suitable, and whether you would benefit most from a metal-on-plastic, ceramic-on-plastic or a metal-on-metal artificial hip joint. Where necessary he may also advise weight loss or recommend other lifestyle changes to aid your recovery following hip replacement surgery.
