Operative Techniques
E

Preoperative Plan

1

Execute a surgical walkthrough

  • describe steps of the procedure to the attending prior to the start of the case
  • describe potential complications and steps to avoid them
F

Room Preparation

1

Surgical instrumentation

  • right angle clamp.
  • right angle retractors (e.g. Sofield or Army-Navy)

2

Room setup and equipment

  • standard OR table (Radiolucent if bone procedures being performed also)

3

Patient positioning

  • supine
G

Skin Incision

1

Make the incision

  • make a 3-5 cm midline incision in the distal third of the posterior thigh.
  • dissection is carried out to expose the semitendinosus medially.
H

Semitendinosus Lengthening

1

Dissect sharply medially to expose the deep fascia.

  • dissect sharply with electrocautery or dissecting scissors.

2

Isolate the semitendinosus

  • the semitendinosus is noted to be the most superficial posteromedial structure and is tendinous distally
  • sharp dissection is used (with electrocautery or dissecting scissors) to expose the deep fascia.
  • incise the deep fascia with tenotomy scissors

3

Place a right angle clamp around the semitendinosus tendon

  • after isolating the semitendinosus, place a right angle clamp around the semitendinosus tendon from lateral to medial
  • lateral to medial placement minimizes the risk of neurovascular damage

4

Transect the semitendinosus

  • the semitendinosus tendon is typically transected at the musculotendinous junction with electrocautery
  • however, if a distal rectus femoris transfer is also being done, the transection is proximal to the musculotendinous junction (to allow enough tendon for the transfer)
I

Semimembranosus lengthening

1

Isolate the semimembranosus

  • incise the fascia over the semimembranosus with tenotomy scissors and isolate the semimembranosus as far anteromedially as possible.

2

Incise the aponeurosis

  • cut the aponeurosis transversely with a 15 blade at 1 or 2 levels
  • leave the underlying muscle undisturbed
  • when 2 cuts are made, the proximal cut is done first so that tissue is still on tension when the distal cut is made

3

Test the release

  • bring the knee into full extension with the ipsilateral hip extended
  • if the knee comes easily to full extension, lateral hamstring lengthening is not needed
  • do NOT check a popliteal angle as this appears to increase the risk of post-operative peroneal neuropraxia
J

Biceps Femoris Lengthening

1

Isolate the biceps femoris

  • sharply dissect laterally (with electocautery or dissecting scissors) through the same midline incision and expose the deep fascia over the biceps femoris
  • incise the deep fascia with dissecting scissors to fully expose the biceps femoris

2

Incise the aponeurotic band

  • incise the fascia over the biceps with a 15 blade
  • identify and isolate the discreet apneurotic band that is located laterally on the biceps
  • transect this band at 1 or 2 levels while leaving the underlying muscle intact
K

Wound Closure

1

Sucbcutaneous closure is with simple sutures of 2-0 absorbable suture

2

Subcuticular closure is with an undyed, running 3-0 absorbable monofilament.
