About this trial
The goal of this clinical trial is to see which type of strengthening exercise with a tight band (blood flow restriction) helps people recover better after ACL reconstruction. The study includes adults after ACL surgery who are doing physiotherapy to rebuild thigh muscle strength and knee function.
The main questions are:
* Does heavy strengthening with blood flow restriction improve thigh strength, knee function, and daily activities more than light strengthening with blood flow restriction after ACL surgery? * Can light strengthening with blood flow restriction give similar benefits to heavy strengthening while putting less strain on the knee?
Researchers will compare a heavy-exercise program plus blood flow restriction to a light-exercise program plus blood flow restriction to see which gives better strength and functional improvements.
Participants will:
* Come for supervised physiotherapy sessions and do knee exercises on a machine, using either heavy or light loads while a cuff on the thigh gently squeezes to reduce blood flow. * Have their leg strength, and knee questionnaires checked several times during the study.

Trial outcomes
Primary outcomes
Muscle Strength
Muscle strength will be measured using Biodex System 4 Pro for concentric quadriceps and hamstring strength at 60°/s and eccentric quadriceps at 60°/s. Recorded parameters: peak torque(Nm/kg), total work(J), and average power(W).
Muscle Girth
Muscle girth will be measured by measuring the mid-thigh circumference using an inch tape at 15cm above the superior border of the patella. The mean of two readings will be recorded
Secondary outcomes
Pain Reduction
Pain will be evaluated using the Numeric Pain Rating Scale(0-10). This refers to the pain the patient experiences in their operated knee and will observe how it changes with administration of the intervention(s). Scale: 0-10 Minimum value: 0 Maximum value: 10 Higher is worse(more pain). Lower is better(less pain)
Blood Flow
The blood flow to the affected knee will be assessed by using infrared thermography(IRT) using standardized imaging protocols(room temperature 20-24°C, 40-60% humidity).
Tolerability and Perception of the Intervention(s)
This will be recorded using a Likert-type questionnaire focusing on comfort, tightness, and willingness to repeat the intervention. Minimum value: 0 Maximum value: 10 Higher scores mean a better outcome. Lower scores mean a worse outcome.
