the areas with Chlorohexidine

SITE OF OPERATION:
1. Pre-scrotal site: 3 cm long incision on the midline in front of the
scrotum.
CONTROL:
• Dorsal recumbency

SURGICAL PROCEDURE
Open Method Closed Method

between middle and medial patellar ligaments.
UPWARD FIXATION OF PATELLA
Articular surface of
patella

Causes of UFP
1. Hereditary: Straight hind limb
2. Debility and poor condition
3. Trauma
4. Abrupt training
5. Laxity of patellar ligaments
6. Overextension of hind limb

• Subcutaneous and deep infiltration with 8 mL of 2%
lidocaine hydrochloride over the medial and middle
patellar ligaments

Surgical Treatment:
Open method Closed Method
Closed method is widely used now a days.
• In this method stab incision is made with B.P Blade
immediately in front of medial tuberosity of Tibia.
• Abscess knife is passed through V shaped groove between
middle & medial ligament facing sharp end towards the
ligament. Then transected facing knife toward operator.
