My name is Dr Laurence Bellaiche, MSK Diagnostic and Interventionnal Radiologist, expert in Sport Medecine Imaging.

I’ve been the radiologist for the French national elite sports teams for more than 15 years.
I started in the late 90’s with the French Football team during the World Championship in France in 1998.
Since then, I’ve been the radiologist of our National teams in Football, Rugby (covering also the World Championship in France in 2007), Tennis (following our teams and covering Roland Garros and Bercy annually for international players too), etc…
Ex-Attachée at the French institute (INSEP) for our Olympic teams.
I’ve also been working for Ballet Dancers at the Opera de Paris and other Pro Contemporary Dance companies
I was the radiologist for the French teams in London for the Olympics in 2012.
I’ve been working for Arsenal FC for more than ten years, by teleradiology, helping their medical team in difficult cases.

I am a member of the International Skeletal Society.
I have been lecturing in Radiology for years in France and abroad.
I am the cofounder and vice-President of the French-Israeli Association of the Radiology, part of the French Society of Radiology.
I am Member of Honor of the Israeli Society of Radiology.
I started in 2008 an annual French-Israeli course in Radiology in Israel, where tens of top-level radiologists from France, Israel and the US have already lectured.

To evaluate the clinical and magnetic resonance imaging (MRI) outcome of arthroscopic rotator cuff repair with the use of leukocyte-platelet-rich plasma (L-PRP) in patients with large or massive rotator cuff tears.

A comparative cohort of patients with large or massive rotator cuff tears undergoing arthroscopic repair was studied. Two consecutive groups of patients were included: rotator cuff repairs with L-PRP injection (group 1, n = 35) and rotator cuff repairs without L-PRP injection (group 2, n = 35). A double-row cross-suture cuff repair was performed by a single surgeon with the same rehabilitation protocol. Patients were clinically evaluated with the Constant score; Simple Shoulder Test score; University of California, Los Angeles (UCLA) score; and strength measurements by use of a handheld dynamometer. Rotator cuff healing was evaluated by postoperative MRI using the Sugaya classification (type 1 to type 5).

We prospectively evaluated the 2 groups at a minimum 2-year follow-up. The results did not show differences in cuff healing between the 2 groups (P = .16). The size of recurrent tears (type 4 v type 5), however, was significantly smaller in group 1 (P = .008). There was no statistically significant difference in the recurrent tear rate (types 4 and 5) between the 2 groups (P = .65). There was no significant difference between group 1 and group 2 in terms of University of California, Los Angeles score (29.1 and 30.3, respectively; P = .90); Simple Shoulder Test score (9.9 and 10.2, respectively; P = .94); Constant score (77.3 and 78.1, respectively; P = .82); and strength (7.5 and 7.0, respectively; P = .51).

In our study the use of autologous L-PRP did not improve the quality of tendon healing in patients undergoing arthroscopic repair of large or massive rotator cuff tears based on postoperative MRI evaluation. The only significant advantage was that the L-PRP patients had smaller iterative tears. However, the functional outcome was similar in the 2 groups of patients.

Level III, case-control study.

Anterior femoroacetabular impingement: an update.

Anterior femoroacetabular impingement can cause early hip osteoarthritis. The typical patient is an adult younger than 50 years of age, often with a history of sporting activities. The main symptom is intermittent pain triggered by static flexion (low seats) or dynamic flexion (during sporting or occupational activities that require repeated hip flexion). The characteristic physical finding is pain triggered by placing the hip in internal rotation and 70 to 110° of flexion. In additional to anteroposterior and false-profile radiographs, lateral Dunn or Ducroquet views should be obtained on both sides to visualize the anterior part of the head-neck junction. Instead of being concave, the head-neck junction is either flat or convex, causing a cam effect that damages the labrum and anterosuperior cartilage. Non-sphericity of the femoral head with an anterior ovoid bulge induces a similar cam effect. In pincer impingement, which is less common, over-coverage by the anterosuperior acetabular rim pinches the labrum between the rim and the femoral head-neck junction when the hip is flexed. Pincer impingement is related to acetabular retroversion or protrusion. Arthrography coupled with computed tomography or magnetic resonance imaging visualizes the morphological abnormalities (e.g., ovoid shape of the femoral head or retroversion of the acetabulum) and detects secondary lesions such as labral tears or separation or damage to the anterosuperior cartilage. Arthroscopy allows removal of the damaged labrum and correction of the morphological abnormalities via femoroplasty to restore the normal concave shape of the neck and/or acetabuloplasty to eliminate over-coverage. Short- or mid-term results are satisfactory in 75 to 80% of patients. However, the presence of degenerative lesions in about two-thirds of patients at the time of arthroplastic surgery limits the probability of achieving good long-term results.
