Cutting guide and method for performing lateral retinacular release
Apparatus and methods are used for severing at least a portion of a lateral retinaculum as part of a lateral release procedure. An elongated guide body has a first, smooth side and second, opposing side having a lengthwise track with a groove. A pushrod having a cutting device is insertable into the track such that the cutting device protrudes from the lengthwise groove, thereby enabling a user to move the pushrod and sever a lateral retinaculum using the cutting device. The cutting device may be a sharp blade or an electrocautery. A method of performing a lateral retinacular release may comprise the steps of inserting the elongated guide body under the skin and subcutaneous fat with the second, opposing side facing a lateral retinaculum; inserting the pushrod into the track of the body; and pushing or pulling the pushrod such that the cutting device severs a lateral retinaculum.
1. Surgical instrumentation for severing the lateral retinaculum with respect to a lateral release procedure, comprising:
an elongated guide body having a lengthwise inner track with proximal and distal ends, a first, smooth lengthwise surface and a second, opposing surface with a lengthwise groove into the lengthwise track;
a pushrod with proximal and distal ends, with the distal end of the pushrod having a single cutting device operative to sever biological tissue, the pushrod being insertable into the track such that the single cutting device protrudes from the lengthwise groove and the second, opposing surface, thereby enabling a user to move the pushrod and sever a lateral retinaculum using the single, protruding cutting device; and
wherein pushrod includes depth markings.
2. A method of performing a lateral retinacular release, comprising the steps of:
providing an elongated guide body having a lengthwise inner track with proximal and distal ends, a first, smooth lengthwise surface and a second, opposing surface with a lengthwise groove into the lengthwise track, and a pushrod with proximal and distal ends, with the distal end of the pushrod having a single cutting device operative to sever biological tissue, the pushrod being insertable into the track such that the single cutting device protrudes from the lengthwise groove and the second, opposing surface, thereby enabling a user to move the pushrod and sever a lateral retinaculum using the single, protruding cutting device;
inserting the elongated guide body under the skin and subcutaneous fat with the second, opposing side facing a lateral retinaculum;
inserting the pushrod into the track of the body; and
pushing or pulling the pushrod such that the cutting device severs a lateral retinaculum.
