Infrapatellar tendon problems
Patellar tendinopathy is inflammation of the Infrapatellar tendon and it is usually associated with activities with repetitive forceful quadriceps contraction.
It presents with localized pain and tenderness near the patellar tendon insertion at the inferior pole of the patellar.
Infrapatellar tendinosis management
Management is usually conservative
- Modify aggravating activities while undergoing treatment and rehabilitation
- Analgesia
- Platelet injection is a consideration
- Dry Needling treatment modality is a consideration
- Rehabilitation focusing on extensor muscle strengthening
- Maintain fitness with upper limb ergometry while rehabilitating
Upper limb ergometry
Leg extension strengthening
Single leg quadriceps strengthening
Infrapatellar strapping

Infrapatellar tendon strapping technique and rehab guidelines under your professional supervision
Ruptured Infrapatellar tendon management
Surgery
- Complete, acute rupture requires surgical repair
- Additional lengthening/graft augmentation/reconstruction procedures may be required for chronic tears
Acute repair using modified Krackow technique
V-Y lengthening procedure of the quadriceps
V-Y lengthening procedure:
- Make a V incision
- Lengthen the quadriceps tendon
- Closure of the distal aspect of the V side to side
