PATELLAR
TENDINOPATHY
DEFINITION
 Jumper’s knee or patellar tendinopathy ,A/K/A
patellar tendonitis is a condition characterized by
inflammation of patellar tendon. This connects
patella to shin bone.
 It is a chronic overuse injury of the patellar tendon
resulting from excessive stress on the knee extensor
mechanism.
 Seen in sports requiring repetitive jumping, running
and kicking. Example: Volleyball, basketball, tennis
,track
Patellar Tendinopathy
DEFINITION
 Acceleration, deceleration, take off and landing
generate eccentric forces that can be 3 times greater
than conventional concentric and static forces.
 These eccentric forces may exceed the inherent
strength of the patellar tendon, resulting in micro tears
anywhere along the bone tendon interface.
CAUSES
 Extrinsic causes:- Error in training
 Intrinsic causes:- Biomechanical flaws (such as tight
hamstring and excess femoral anteversion and jumping
mechanics)
CLINICALFEATURES
1) Dull, aching anterior knee pain after a strenous
exercise session.
2) Onset:- Insidious
3) Localized
4) Stiffness or pain after prolonged sitting or climbing
stairs
5) Swelling
FOURPHASES
Phase 1 :- Pain is after activity only and is not associated
with functional impairment.
Phase 2 :- Pain is present during and after activity but
does not limit performance and resolves with rest.
Phase 3 :- Pain is present continually and is associated
with progressively impaired performance.
Phase 4 :- Compete tendon rupture
EXAMINATION& LIMITATION
PHYSICAL
EXAMINATION
FUNCTIONAL
LIMITATION
1) Tenderness :- Positive
at inferior pole of
patella
2) Crepitus and pain with
compression of the
patellofrmoral joint
3) In advance disease,
quadriceps atrophy
1) Inhibition of knee
extension impairs
atheletic performance
2) Walking difficulty
3) Difficulties with
ascending or
descending stairs
INVESTIGATION&TREATMENT
INVESTIGATION TREATMENT
 X-RAY
 Ultrasound
 MRI
 Conservative :-
Ultrasound,
iontophoresis, NSAID,
Corticosteriod
 Surgical :- Resection of
tendon with resuturing
of tendon
TREATMENT
 Stretching exercises
 Strengthening exercises; Focus on eccentric
strengthening
 Knee brace , cap, counterforce straps
 Sports – specific drills and training
 Eccentric squats
 Leg presses
 Slant board exercise
Decline squat and Step squat
Split Squat
