Recent publications from The Hospital for Special Surgery (HSS) in New York (1) and the University of Sassari in Italy (2) compared NanoFx® to microfracture and k-wires for marrow stimulation and its effect on the subchondral bone architecture. The HSS study demonstrated that larger instruments caused more disruption to the bone and the Italian results showed that the deeper NanoFx® (Nanofracture) perforations led to a better restoration of the subchondral bone architecture at 6 months. An additional concern highlighted in the Zedde et al. publication was that 75% of the microfracture subjects had subchondral cysts, whereas no cysts were found in the Nanofracture group.
Within the past 10 years, the Sports Medicine community has shifted its focus away from the tissue that eventually fills the defect area and towards the osteochondral unit. As the HSS article commented, “any technique that can change the structure of the subchondral bone has the potential to affect the biomechanics of the osteochondral unit, the repair process, and the overall cartilage resurfacing outcome.” Similar to the construction of a house, the foundation has become just as important, if not more, than the roof.
Marrow stimulation remains one of the most common first-line treatment options for cartilage defects. However, the decline in clinical outcomes seen with microfracture at 18-36 months after the procedure22-28 continues to drive surgeons to search for a new alternative to the standard of care. The research highlights three key elements that affect outcomes when performing marrow stimulation techniques:
- Channel depth
- Channel diameter and
- Subchondral bone disruption
Chen et al demonstrated that to access the marrow-rich subarticular spongiosa, a depth greater than 6mm was best. Hoemann and colleagues assessed the bone disruption of awls and found that the larger and deeper the awls went, the more compaction damage there was to the lesion surface. In 2014, Eldracher et al. compared marrow stimulation using 1.0 or 1.8mm drills at a standardized depth of 10 mm in an ovine model.20 The smaller 1.0mm subchondral drill holes that reflected the physiological trabecular distance significantly improved osteochondral repair in a translational model more effectively than larger drill holes.
The goal of marrow stimulation is to perforate the bone to allow access to the marrow compartment which contains the stem cells, growth factors and healing proteins necessary to form a superclot that includes the essential biological elements needed to initiate a repair of the defect site. Increasing type II collagen and reducing type I is also seen as vital to the development of a more robust cartilage-like tissue. When the data from these various sources is combined with the Nanofracture® comparative data from HSS and the University of Sassari, a clear picture for a more successful marrow stimulation repair emerges. The ideal instrument must be able to perforate deeply into the bone, have a diameter of 1mm to match the trabecular distance, do so without disrupting the subchondral bone unit, self-seal to avoid cyst formation all while stimulating type II collagen synthesis in the defect area to improve biological healing.
Smaller, Deeper, Better is not simply a marketing slogan but rather the criteria for a new standard of care in marrow stimulation.

Have you ever wondered how much time it took other Toe HemiCAP Patients to return to their favorite activities after surgery? The chart below was compiled to help answer your questions.
Typical Patient Function & Activity Milestones after Hemiarthroplasty or Total Toe Replacement
Based on their experience, surgeons rated the time it took for patients to achieve certain milestones after surgery such as driving a car, walking in shoes and returning to work, activity or sport. Typically, patients are able to perform the activities of daily life, including returning to work, 2-6 weeks after surgery.
Following Toe HemiCAP® hemiarthroplasty, or ToeMotion® Total Toe replacement, no restrictions on job, sports or activity were recommended. Following these procedures, most patients are expected to return to work within 2 weeks after surgery (66.7%) or within a 15-30 day range (33.3%). The time to return to work was classified as equal or faster than cheilectomy, faster than other implants and faster than fusion. Sports participation was started at a mean of 49.3 days and the satisfaction regarding the return to sport and an active lifestyle was rated as Excellent (66.7%), Very good (33.3%) or Good (16.7%).

A small group of expert surgeons who together have performed more than 1000 surgical procedures since 2005 using the Toe HemiCAP® System were recently asked to share their experience in form of a survey.
The group included male and female orthopaedic (MD) and podiatric surgeons (DPM) who were in practice performing foot and ankle surgery for more than 17 years on average. Together, their expertise is based on over 100 years diagnosing and treating patients with foot and ankle problem
Surgeons were asked about their experience with the Toe HemiCAP and ToeMotion implants, as well as different toe fusion systems. Their response provided insight into the
- Return to work and activity
- Pain relief and functional improvements
- Length of the procedure and hospital stay
- Typical recovery with physiotherapy and rehabilitation
If you are considering surgery as an option for the treatment of painful toe arthritis, this survey may provide additional information to help you make an informed decision. It may also be helpful in guiding you towards a series of questions you may want to ask your doctor before deciding on the course of your treatment.
There are many things that can accelerate or make arthritis worse. One of the most problematic accelerators is Obesity. By definition, obesity means that a person’s body weight is 20% higher than it should be and they have a body mass index (BMI) over 30. If a person’s BMI is between 25 & 29.9, they are considered overweight. Obesity is a major risk factor for the development of osteoarthritis, which affects nearly 1 out of every 5 adults in the US. Reports show that by 2030, it’s estimated that over 67 million adults will suffer from osteoarthritis, a whopping 20% of the US population. Obesity can not only accelerate the progression of the disease but osteoarthritis can be much more severe for the obese and overweight and is just one more reason why weight loss is so important.
It’s a well-known fact that each pound you lose reduces the pressure on your knee joints by 4 pounds. Once cartilage is lost the damage cannot be undone. However, weight loss can and controlling your weight be very beneficial by slowing the progression of the disease. The larger the weight loss, the more intense an effect it has on your joints, reducing knee degeneration and slowing osteoarthritis. For example, every 11lbs a woman loses (2 BMI Points), the risk of developing OA dropped greater than 50%.
The Arthritis Foundation says that, “obesity is the number one preventable risk
factor for osteoarthritis.” Exercising on its own may not be the solution to weight loss though, especially if working out or being active is too painful. Diet plays a very large role in shedding the pounds and is particularly important in reducing the stress on your joints so that activity becomes less problematic. By combining healthy eating habits (i.e. vegetables and fruit) and drinking lots of water with exercise will aid in weight loss.

In the US, approximately 80,000 microfracture procedures are performed each year with the estimated number being much larger. However, in 2015, the Journal of Arthroscopy (JARS) published editorials calling into question whether there was evidence to support the continued use of microfracture as a joint preservation method because new evidence on subchondral bone disruption and marrow channel access have highlighted the mechanical and design shortfalls in traditional microfracture procedures. This recent Expert Opinion Review summarizes the contemporary literature.
New Microfracture Study:
Considering that microfracture surgery is one of the most frequently used procedures for cartilage repair, the Hospital for Special Surgery in conjunction with Cornell University recently performed a comparative study where researchers found that smaller diameter instruments (Nanofracture®) showed the best prospects of accessing repair cells and were substantially less damaging when compared to traditional microfracture/k-wire instruments.
Based on their findings showing considerable differences, the authors concluded that the choice of cartilage repair technique should be carefully considered.
Everyone knows that alcohol can damage the liver, but did you know that excessive amounts of alcohol can have lasting effects for those suffering with painful joints & arthritis? While you may have recovered from all of the adult beverages you consumed over the holidays, your joints could still be suffering.
Alcohol is a diuretic (a drug or substance that increases the passing of urine) that forces your body to lose water, which in turn, dehydrates your ligaments & tissues. Your joints rely heavily on having sufficient fluids to move smoothly & function properly so your ligaments, which contain a lot of water, are usually the first structures in the body to be affected when dehydration begins. Because of this, your joints will have insufficient fluids to provide the smooth, soft cushion needed for movement and in turn can result in agonizing joint pain, especially for those with underlying arthritis symptoms.
Not only can mixing different types of alcohol get you in trouble (Beer before liquor), but mixing alcohol with certain arthritis medications can cause real problems for your body too. Certain long-term rheumatoid arthritis medicines, such as DMARDs, can cause liver damage on their own but when mixed with alcohol, your odds for liver damage increase exponentially.
Though it has not yet been conclusively proven, many doctors believe there is a real connection between drinking alcohol & joint pain and suggest drinking in moderation. It may not be necessary to forego alcohol all together but drinking in moderation can minimize joint dehydration, allowing your joints to function normally.
According to WebMD wine drinkers may be the exception. According to the article, wine didn’t result in an increased risk of gout or arthritis, which is good news for the wine crowd! Keep in mind that excess alcohol may leave you with a joint hangover long after your head has cleared and don’t forget to Hydrate!

The weather is cooling down, trees are changing color and the wind and rain are knocking the leaves down at a rapid pace. Yards are covered with this autumn mess making yard work inevitable. According to the Consumer Product Safety Commission, in 2014, there were almost 50,000 raking related injuries reported in the US with close to 500,000 ladder injuries. Common yard work activities can lead to pulled muscles, joint pain, torn ligaments and a sore back.
Use these tips to help avoid injuries:
- Stretch – Remember to warm up your muscles and stretch before beginning yard work
- Use the Right Equipment – Use a rake that is the right size and length for your height.
- Take Breaks – Every so often your body will need a rest. Rehydrate & Stretch to alleviate muscle strain
- Use Proper Form – When raking, make sure to stand up straight and avoid slouching over. Use your legs instead of your back. (don’t bend at the waist, but bend at the knees). Also switch arms every so often.
- Practice Ladder Safety – Climb ladders slow & steady to help avoid falling. Check your ladder for loose screws and hinges and make sure to select the proper ladder for the job and to position it correctly before climbing to clean out gutters. (One to four rule)

A recent study, published in the KSSTA journal, compared two different implant types used in Patellofemoral Arthroplasty (PFA):
- Group I consisted of an inlay (HemiCAP® Wave, Arthrosurface, Franklin, MA)
- Group II was based on an onlay design (2nd generation, Journey™ PFJ, Smith & Nephew, Andover, MA)
All patients were matched for age, gender, body mass index, and follow-up period with an independent observer evaluating the patients prospectively. Follow-up was 26 months for the inlay group and 25 months for the onlay cohort. No significant progression of tibiofemoral osteoarthritis (OA) was observed within the inlay group, whereas over half of the onlay group showed progression of knee OA (53%). While the mechanism of the disease progression was unclear, the authors hypothesized that the “onlay” device overstuffed the patellofemoral joint leading to chronic synovitis. The secretion of pro-inflammatory cytokines resulting from the synovitis is a known risk factor for OA. In addition, raising the height of the trochlea, which comes from using an onlay device, may have adverse effects on the extensor mechanism. This may increase the pressure in the femoral-tibial joint as the knee moves from extension to flexion. Based on this study, the inlay PF HemiCAP® design may improve long-term results and survival rates after isolated PFA.

The past few weeks has brought heat & humidity so unbearable Continue reading →
For those of us living above the equator, summer is finally here and the heat & humidity seems to be getting worse. Weather experts predict that 2015 could be the hottest year on record with heat waves are already creating havoc in places like Europe & Asia. For those suffering from arthritis or chronic joint pain, the summer weather can be unbearable. Our joints contain sensory nerves that continuously respond to the changing weather. Temperature and humidity can alter the level of fluid that fills your joints resulting in inflammation and pain and it can also affect the stiffness or laxity in your tendons, muscles and ligaments.
Here are some tips on how to deal with the heat:
- Stay Indoors: Preferably in an air conditioned environment as that will regulate both temperature and humidity. Too much time outside can cause the amount inflammation in your joints to sky-rocket making anti-inflammatory medication less effective.
- Stay Hydrated: Drink lots of water and fluids, such as Gatorade, to maintain your fluid and electrolyte levels. Caffeine drinks, alcohol and high sugar drinks can make you dehydrated, so steer clear of those. To keep your movement fluid drink lots of fluid! Hydration is KEY!
- Wear loose, natural fiber clothing: Wearing loose, cotton clothes and linen fabrics that allow your body to breathe helps to evaporate sweat which keeps your body cool.
- Take a Swim: Taking a dip in a pool is not only great for cooling off but the buoyancy of the water also relieves the pressure on your joints. Water activities are refreshing and help you stay active when the extreme heat is too much for outdoor exercise. Remember, swimming is a low impact cardio exercise that is great for people suffering from Arthritis or joint pain.
Heat & Humidity can be a nuisance, but don’t let it stop you from enjoying the summer season!
We would love to hear from you! How do you keep your arthritis symptoms at bay and stay cool in the summer? Any advice for others?
A few weeks ago in Lyon, France, Arthrosurface, along with the other leading orthopaedic device companies, exhibited at the ISAKOS Congress. ISAKOS is a global society of surgeons who are focused on advancing worldwide education, research and patient care in arthroscopy, knee surgery and orthopaedic sports medicine. The Congress meets every other year with locations rotating through the Americas, Europe, Asia and Africa. The next congress will be held in Shanghai in 2017. Surgeon attendees travel from all over the world to see the latest advancements in Orthopaedic Surgery. The majority of these attendees are focused on specific joints (i.e. Knee or Shoulder) and sports medicine in their practices.
ISAKOS has recognized that there is a significant gap between conservative treatments such as Physio-Therapy and anti-inflammatory treatments, and total Joint Replacements. To help address this gap, they are focusing their education efforts on identifying which technologies best match the patients’ disease severity and their activity demands. They found that biology treatments, such as injections, PRP, and stem cells, with different grafting and scaffolding technologies for cartilage regeneration as well as minimally invasive, bone & tissue preserving implant systems. Arthrosurface offers both biology treatments (NanoFx) and Joint Preserving Implants (HemiCAP).
During the Congress, we held a Shoulder HemiCAP Luncheon workshop lead by Dr. Anthony Miniaci from the Cleveland Clinic, that was at full capacity with not one empty seat in the house! We had an excellent booth location, and the products of interested there were NanoFx (micro fracture), the Patello Femoral Wave HemiCAP and the Stemless Total Shoulder.
