A PROSPECTIVE STUDY DONE TO EVALUATE THE FUNCTIONAL OUTCOME OF KNEE AFTER ARTHROSCOPIC POSTERIOR CRUCIATE LIGAMENT RECONSTRUCTION USING IPSILATERAL PERONEUS LONGUS AUTOGRAFT.

Abstract

Background: PCL is one of the major ligaments of the knee joint which stabilizes the tibia on the femur. It prevents posterior translation of the tibia.

Aims and Objectives: To evaluate the functional outcome of knee joint after arthroscopic posterior cruciate ligament reconstruction using ipsilateral peroneus longus autograft and also to assess the donor site morbidity.

Methods: A prospective study was conducted on 24 patients in the department of orthopaedics, Indira Gandhi Institute of Medical Science, Sheikhpura, Patna. All patients (male or female; age range 18-40 years) with PCL tear coming in OPD and emergency department of the Indira Gandhi Institute of Medical Sciences, Patna; were included in the study.

Results: The mean age of the patients was 29.5 years with a range from 19 years to 39 years. Most of the patients (37.5%) were in the age group of 25-32 years followed by 33.3% in the age group of 33-40 years, and 29.2% aged 18-25 years. All the patients were males. There was a significant improvement in IKDC and Tegner Lysholm score at 6-weeks, 3-months, 6-months, 1-year, 1.5 years, and 2-years compared with pre-operative IKDC and Tegner Lysholm score. The donor site morbidity was assessed with Foot and Ankle Disability Index (FADI) and found to be unaffected.

Conclusion: Arthroscopic single bundle PCL reconstruction using ipsilateral peroneus  longus  tendon  autograft had significant improvement in functional outcome of the knee based on IKDC and Tegner Lysholm score. Ankle function was also found to be preserved based on FADI score at 2-years follow-up.
