PURPOSE Open plantaris tendon excision and ventral paratendinous stripping is a recognised treatment option in selected patients with non-insertional Achilles tendinopathy. The aim of this study was to develop a minimally invasive outpatient technique of ultrasound guided plantaris tendon release (UPTR). METHODS A 19 gauge needle, 15 gauge scalpel blade, hook knife (Smith and Nephew, Boston, MA, USA) and a beaver blade (Arthrex, Naples, FL, USA), were used under ultrasound guidance to identify and divide the plantaris tendon in 12 cadaveric legs. Specimens were dissected to identify whether division of the plantaris tendon had been successful. UPTR was subsequently performed on patients. RESULTS The 15 gauge scalpel blade, hook knife (Smith and Nephew, Boston, MA, USA) and beaver blade (Arthrex, Naples, FL, USA) were all able to cut the plantaris tendon. However, on dissection the hook knife (Smith and Nephew, Boston MA) caused less damage to surrounding structures. Subsequently, the plantaris tendon was successfully divided in three patients using UPTR technique without complication. CONCLUSION UPTR is a viable technique for treating plantaris related non-insertional Achilles tendinopathy.

可以在超声引导下释放足底肌腱：超声引导足底肌腱释放（UPTR）在非插入式跟腱病治疗中的技术描述。

目的开放性plant肌腱切除术和腹侧腹旁剥离术是某些非插入式跟腱病患者的公认治疗选择。这项研究的目的是开发一种超声引导的plant肌腱释放（UPTR）的微创门诊技术。方法在超声引导下使用19针，15手术刀刀片，钩刀（Smith and Nephew，美国马萨诸塞州波士顿）和海狸刀片（Arthrex，那不勒斯，佛罗里达州，美国）在超声引导下识别并分离plant肌腱。在12条尸体腿上。解剖标本以确定identify肌腱的分裂是否成功。随后对患者进行了UPTR。结果15规格的手术刀刀片，钩刀（史密斯和侄子，美国马萨诸塞州波士顿）和海狸刀片（Arthrex，那不勒斯，佛罗里达州）美国）都能够切断plant肌腱。但是，在解剖时，钩刀（Smith和Nephew，马萨诸塞州波士顿）对周围结构的损坏较小。随后，使用UPTR技术将successfully肌腱成功地分为三例，无并发症。结论UPTR是一种可行的技术，用于治疗足底相关的非插入式跟腱病。
