The Twenty-fifth Annual Summer Meeting of the American Orthopaedic Foot and Ankle Society (AOFAS) was held 16-18 July 2009 at the Westin Bayshore Hotel in Vancouver, British Columbia, Canada. There were 521 registered attendees, including 339 (65%) individuals from 42 of the United States and 182 (35%) attendees from 32 countries outside the United States.

ABSTRACT: Osteochondral injury of the talus can be challenging to treat because the damaged articular cartilage has a poor intrinsic reparative capability. Autologous Chondrocyte Implantation has become an effective means for treating persistent cartilage lesions that fail to respond to routine ankle arthroscopy. The purpose of this study was to assess the results of Matrix-induced autologous chondrocyte implantation (MACI) for the treatment of osteochondral defects of the talar dome using a technique which does not require an osteotomy of the tibia or fibula. A prospective investigation of MACI was performed on ten patients with full-thickness lesions of the talus. The patients had a documented talus lesion on MRI, failure of conservative treatment and arthroscopic debridement/curettage, persistent ankle pain and swelling, the absence of tibiotalar arthritis and a stable ankle. Five males and five females, with an average of 1.7 previous procedures prior to Matrix-induced autologous implantation, were included in this study. All patients were available for followup at 1 and 2 years. Lesions were graded during the harvesting procedure using the Cheng-Ferkel grading system, the Outerbridge classification, and the International Cartilage Repair Society system. Clinical and functional evaluation was done preoperatively, and at 1 and 2 years postoperatively using the AOFAS hindfoot evaluation and the SF-36 Health Survey. Preoperative AOFAS hindfoot scores were 61.2 (range, 42 to 76) which improved 1 year postoperatively to 74.7 (range, 46 to 87) (p < 0.05) and 2 years postoperatively to 73.3 (range, 42 to 90) (p = 0.151). At both 1 and 2 years postoperatively, the results of the SF36 evaluation demonstrated a significant improvement in the Physical Functioning (p = 0.002) and Bodily Pain (p < 0.001) components. Subjectively, all ten patients believed this procedure helped them. The results of this study suggest that MACI may be an effective way to treat full-thickness lesions of the talus using harvested chondrocytes from the talus without malleolar osteotomy. We recommend it for patients who do not respond to initial curettage and microfracture.Foot & Ankle International 09/2010; 31(9):747-53. DOI:10.3113/FAI.2010.0747 · 1.51 Impact Factor

ABSTRACT: Posterior ankle impingement syndrome (PAIS) was first described in ballet dancers but is increasingly being diagnosed in other sports. Operative treatment may be indicated when nonoperative measures have failed. Traditionally, operative treatment has involved an open approach; more recently, posterior ankle arthroscopy has been employed. This study was conducted to describe the factors that influence return to play in professional athletes after posterior ankle arthroscopy for posterior ankle impingement syndrome. Case series; Level of evidence 4. A consecutive series of 28 elite professional soccer players who had clinically and radiologically diagnosed posterior ankle impingement syndrome that failed to respond to nonoperative treatment underwent posterior ankle arthroscopy for bony or soft tissue posterior ankle impingement syndrome over 5 years. Of the 28 players, 27 were available for follow-up. Five had a diagnosis of soft tissue impingement and underwent debridement with flexor hallucis longus release, 13 had a symptomatic os trigonum that was excised arthroscopically, and 9 had removal of a bony avulsion fragment from the posterior ankle ligament complex. The mean length of time to return to training postoperatively was 34 days and return to playing was 41 days (range, 29-72 days). The duration of symptoms before surgery and excision of bony impingement were significantly correlated with the time to return to training and playing. There were no major complications and no reoperations at an average of 23 months of follow-up (range, 15-49 months). Posterior ankle arthroscopy is safe and effective in the treatment of posterior ankle impingement syndrome in the elite soccer player, with return to training expected at an average of 5 weeks.The American Journal of Sports Medicine 12/2009; 38(1):120-4.

ABSTRACT: The purpose of this study was to evaluate the clinical outcomes and objective isokinetic dynamometry on a cohort of patients with chronic insertional Achilles tendinosis, who underwent surgical reconstruction using an FHL tendon autograft transfer through a single incision. Forty patients (16 male and 24 female; mean age, 57 years; age range, 39 to 76 years) with persistent chronic Achilles tendinosis were evaluated after surgical reconstruction at an average of 27 months after surgery. At the time of final followup, ankle strength and active range of motion (AROM) were evaluated using Biodex isokinetic dynamometry. Additionally, patients were assessed with AOFAS Ankle Hindfoot scores, pain on a Visual Analog Scale (VAS) and their self-reported level of satisfaction (Very Good, Good, Fair, Poor). We found no loss of plantarflexion strength or plantarflexion power in the operated ankles; an average of 4-degree loss of AROM was found. The study population scored an average of 96/100 for the total AOFAS-AH score post-repair. The average VAS decreased from 7.5 pre-op to 0.3 post-op. Thirty-eight of 40 patients (95%) were satisfied with their outcome (rated Very Good or Good), two patients rated their outcome as Fair and none as Poor. For individuals with chronic insertional Achilles tendinosis, operative repair using an FHL tendon with the single-incision technique achieved a high percentage of satisfactory results as well as excellent functional and clinical outcomes including significant pain reduction.Foot & Ankle International 04/2009; 30(3):197-204.
