Cementless Unicompartmental Knee Replacement: Good or Better Than Cemented

Orthopedic surgeons from the United Kingdom have proven for themselves that cementless unicompartmental knee replacements are as good (if not better) than cemented implants of the same type. They conducted this preliminary study using the Oxford unicompartmental knee replacement. The study was partially funded by the company (Biomet) that makes […]

Can Posterior Cruciate Ligament Reconstruction Prevent Osteoarthritis?

The posterior cruciate ligament (PCL) is one of two ligaments that criss-cross inside the knee joint to hold the two leg bones (femur and tibia) together. The second (more commonly injured) ligament is the anterior cruciate ligament (ACL). These two ligaments provide stability to the knee joint while still allowing […]

Total Knee Replacement: One at a Time? Or Both Together?

Patients with painful arthritic knees may wrestle with the decision to have them replaced one at a time (two separate surgeries and rehab) or both at the same time. The proposed advantages of the simultaneous bilateral knee replacements are decreased costs and shorter recovery time. The results (or outcomes) are […]

Five “Plusses” for New Superficial Quadriceps Graft

Around the world, surgeons are working to find better ways to reconstruct the medial patellofemoral ligament (MPFL). We reported on a previous study from China on this topic. Now here is another from India. The MPFL is the stabilizing ligament that helps keep the patella (knee cap) tracking up and […]

What to Expect After Repeated Knee Surgeries for Anterior Cruciate Ligament

So many people in this country are having anterior cruciate ligament (ACL) surgery, it’s beginning to seem like a common place problem/solution. ACL ruptures haven’t reached epidemic proportions but with 200,000 cases reported each year, it is a significant problem. Surgery to reconstruct the torn ligament is quite successful. But […]

How Meniscus Tears Affects the Knee Over Time

As more and more aging Baby Boomers start to develop knee osteoarthritis, researchers are focusing on the whys and wherefores of this condition. Studies have already shown that removing a torn meniscus (knee cartilage) puts patients at a significantly greater risk of developing knee osteoarthritis later on. But what happens […]

The Future of ACL Grafts: Is It Here Yet?

Right now the “gold standard” for reconstructive surgery of the anterior cruciate ligament (ACL) is graft replacement of the ruptured tendon. The surgeon uses either a piece of the patient’s patellar tendon or hamstrings tendon. Tiny tunnels are drilled through the bone to secure and attach the graft tissue. But […]

Joint Infection After Knee Replacement: Why and What to Do About It.

With more and more older adults getting knee joint replacements, the risk of deep joint infection becomes a concern. It is one complication that can put the entire knee (and new joint) at risk and is the number one reason for additional surgery. How often does it happen? Why does […]

New Y-Graft Technique for Dislocating Kneecap

The patella or kneecap is a marvelous and complex structure. Held over the knee joint by soft tissue structures, it moves or “tracks” up and down with knee motion. Anatomists are still exploring and learning how the patellar tracking mechanism really works. Understanding normal patellar anatomy and kinematics (movement) will […]

Platelet-Rich Plasma Outperforms Shock Wave Therapy for Jumper’s Knee

Running and jumping over and over often leads to a condition in athletes known as patellar tendinosis or jumper’s knee. Pain along the front of the knee during the activity that goes away with rest is a cardinal symptom of this condition. Dancers, gymnasts, and basketball, soccer, and volleyball players […]

Fear-Based Problems After Total Knee Replacement

Before reaching the point of needing, wanting, and accepting a total knee replacement for joint arthritis, many people become fearful of movement (kinesiophobic). Their level of pain causes them to start avoiding certain movements and activities at home and work. This pattern of behavior is called fear-avoidance. Long periods of […]

Knee Pain and Joint Motion Improved for Arthritis Using Aquatic Therapy

Many studies show the benefit of exercise for people with knee osteoarthritis. But pounding the pavement (walking) can increase pain. Aquatic therapy in a pool of warm, supportive water is one way to get the needed exercise without the added stress. In this study from the University of Florida, the […]

One PRP Injection May Be All That is Needed for Painful Knee Arthritis

Platelet-rich plasma (PRP), also known as blood injection therapy, continues to be investigated by researchers. They are looking for a way to control painful symptoms from knee osteoarthritis. Efforts to regenerate lost joint cartilage using this type of treatment may also help slow down the disease process. Scientists still aren’t […]

Using MRIs to Predict Recovery From Hamstring Injury

Many athletes involved in running sports (e.g., rugby, soccer, football, basketball) with fast starts and sudden stops injure their hamstring muscle. Of course, the first thing they want to know is how long will it take to recover and get back in the game? The answer is not always so […]

High Failure Rate with MACT for Young Knees

Orthopedic surgeons from Italy report a high failure rate using matrix-assisted autologous chondrocyte transplantation (MACT) for young patients. Forty-four patients between the ages of 20 and 58 years of age with osteoarthritis from damage to the knee joint cartilage were included in the study. Each one had a hole or […]

One-Fourth of All Meniscal Repairs Fail

There is a 24 per cent failure rate for meniscal repairs five years after the operation. This is true whether you have a medial or lateral repair. The rates are the same if you have an intact or damaged anterior cruciate ligament (ACL). And the five-year outcomes are the same […]

Patellar Resurfacing as Part of a Knee Replacement: Yes or No?

Most people don’t realize that a total knee replacement can involve three component parts. There is the femoral side of the joint (the bottom portion of the femur or upper thigh bone). Then there is the tibial side of the joint (the upper part of the tibia or lower leg […]

Reducing ACL Injuries in Women

It is a well-known fact that women athletes are at greater risk for knee injuries compared with men. In particular, anterior cruciate ligament (ACL) injuries seem to plague female athletes much more often than men. In this article, orthopedic surgeons from the Department of Orthopaedics and Rehabilitation at Yale University […]

Devastating Problem After Joint Replacement: Infection

As a natural consequence of rising numbers of total hip and total knee joint replacements has been the increase in number of postoperative infections. This complication can have devastating results. It is a complex and challenging problem to solve for a number of reasons. First of all, general health and […]
