Return to Play After Open Calcaneoplasty for Insertional Achilles Tendinopathy With Haglund Deformity in Competitive Professional Athletes

BACKGROUND: Surgical treatment of insertional Achilles tendinopathy with Haglund deformity in highly competitive professional athletes has not been previously investigated. PURPOSE: To assess clinical outcomes, including return to play (RTP), after surgical treatment of insertional Achilles tendinopathy in professional athletes. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: This retrospective study included 20 professional athletes who were surgically treated for insertional Achilles tendinopathy and had at least 2 years of follow-up. An open longitudinal lateral approach was used for the operation, without violation of the Achilles tendon. Outcome evaluation included American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, subjective patient satisfaction, mean time of return to competition (RTC), and rate of RTP. We defined RTC as return to an official match for at least 1 minute and RTP rate as the percentage of patients who were able to participate in at least 2 full seasons. A subgroup analysis was performed to compare the RTP and no-RTP groups. RESULTS: The AOFAS score improved significantly from preoperatively to the final follow-up (from 65.1 to 88.4; P < .001), and 75% of the patients reported good to excellent satisfaction. The mean time of RTC was 7.45 months (range, 4-18 months), and the rate of RTP was 60%. The RTP group had a significantly lower mean body mass index than did the no-RTP group (22.03 vs 23.86, respectively; P = .005) and faster mean RTC (5.0 vs 11.1 months, respectively; P < .001). CONCLUSION: Open calcaneoplasty for surgical treatment of insertional Achilles tendinopathy with Haglund deformity in highly competitive professional athletes should be approached cautiously. Our patients had a 7.5-month recovery period before return to their first official match, and only 60% of the patients returned to their sports activity and participated in at least 2 full seasons. Lower body mass index and a faster RTC after surgery were related to longer functional maintenance.
