Background. Most patients with Achilles tendinopathy (AT) are treated successfully with physiotherapy ie eccentric calf training. In some patients gastrocnemius contracture persists. Three other publications have reported improvement in AT following gastrocnemius release, but this is the first series of patients to have proximal medial gastrocnemius release (PMGR) for AT. The purpose of this study was to review patients with refractory non-insertional and insertional AT treated by PMGR with a minimum followup of 18 months. Method. Sixteen PMGRs were performed over a two year period. Nine patients (10 PMGRs) were available for followup. The mean age of patients was 45 (Range, 25 to 63) years, with five female and four male subjects. The average followup period was 2.5 (range, 1.7 to 3.3) years. The sample was divided into non-insertional and insertional tendinopathy, with five PMGRs per group. Outcome measures were VAS scores, VISA-A scores, AOFAS ankle-hindfoot score and overall satisfaction. Complications and further procedures were also recorded. Results. At an average of 2.5 years follow-up, two-thirds of patients were highly satisfied. The non-insertional tendinopathy group enjoyed better results than the insertional group: mean improvement in VISA-A scores were 59% (non-insertional) vs 22% (insertional); mean AOFAS scores improved by 29% (non-insertional) vs 15% (insertional). The improvement in the non-insertional group was statistically significant (p < 0.05) in all three outcome measures. Our findings further support that insertional tendinopathy is more resistant to calf stretching/lengthening treatments. Conclusion. In contrast to open or percutaneous debridement of the Achilles tendon, PMGR is a day surgical procedure that is well tolerated with excellent wound healing. Patients with non-insertional tendinopathy who have failed conservative treatment can expect significant improvement with VISA-A scores normalising after the procedure. We recommend PMGR for patients suffering recalcitrant non-insertional AT in whom gastrocnemius contracture persists despite an eccentric stretching program

Introduction. Achilles tendinosis results from a chronic degenerative process within the tendon. Topaz micro-debridement aims to restore the degenerate micro-architecture within the tendon reducing painful symptoms experienced by patients. Topaz micro-debridement has been used to successfully treat upper limb tendinopathies but its application to tendinopathies of the foot and ankle is relatively new. This study aims to assess the functional outcomes following topaz radiofrequency micro-debridement for Achilles tendinosis. Materials/Methods. All cases of topaz micro-debridement for Achilles tendinosis were identified from hospital records spanning a five year period. VISA-A assessment questionnaires were sent to these patients to assess the patients functional status pre and post-surgery. Patients were asked to comment on their overall satisfaction and to report any complications they had experienced. Eight responses were received and included in analysis. Hospital records and imaging results were investigated for those that responded. Results. Average VISA-A scores improved from 18/100 to 63/100. The difference between the pre and post-surgery group was significant at the 0.02% level. All cases demonstrated objective improvement in functional outcome. Seven cases reported overall satisfaction but one was complicated by Achilles tendon rupture seven weeks following the procedure. This is the second reported case of rupture noted in current literature. Conclusion. This study confirms topaz micro-debridement is an excellent treatment for Achilles tendinosis, but that rupture is a real risk which persists for at least two months following the procedure. We would therefore recommend the procedure with a suitable period of rehabilitation to ensure full recovery
