Case description: The patient was an adult of 58 years who suffered a complete isolated tear of the right anterior cruciate ligament
(ACL). He underwent an arthroscopically aided reconstruction of ACL 12 days after the injury with a Semitendinosus-Gracilis
autograph. After 3 weeks, the patient visited the physiotherapy clinic and at that time had trouble bending the knee, trouble
walking, and was unable to sit with the knee flexed. Rehabilitation started at a rate of one session a day, six days a week.
Rehabilitation activities included exercises to improve ROM coordination, and strength exercises, and home workout routine with
regular monitoring of training intensity. This case focuses primarily on rehabilitation of older adults. Outcome: The surgery combined
with the comprehensive rehabilitation plan allowed the patient to begin work 9 weeks after surgery. The recovery can take longer in
older adults, but in this case the recovery is seen more rapidly. Discussion: This case study indicated that in some of the cases of ACL
reconstruction, the early return to functional activities after ACL reconstruction is possible. Conclusion: This case study suggests that
surgery combined with the comprehensive rehabilitation plan used after reconstruction of ACL, including home exercise plan with
continuous monitoring of the strength of the training, allowed the patient to return to work early after surgery.
