After undergoing MACI (Matrix-Induced Autologous Chondrocyte Implantation) for cartilage repair, exercises play a crucial role in the rehabilitation process. Here are some exercises commonly recommended during the recovery phase:
- Range of Motion (ROM) Exercises:
- Ankle pumps: Move your foot up and down to maintain ankle mobility and prevent stiffness.
- Knee extensions and flexions: Gently straighten and bend your knee to maintain or improve your range of motion.
- Heel slides: Lie on your back and slide your heel towards your buttocks, bending your knee.
- Strengthening Exercises:
- Quadriceps sets: Tighten the muscles on the front of your thigh by pressing the back of your knee down into the bed or floor.
- Straight leg raises: Lie on your back and lift your leg off the ground while keeping it straight, engaging your quadriceps muscles.
- Hamstring curls: Use a resistance band or a machine to flex your knee against resistance, targeting the hamstring muscles.
- Weight-Bearing and Balance Exercises:
- Partial weight-bearing exercises: Perform activities like standing with support or using a walker to gradually increase weight on the operated leg.
- Balance board exercises: Stand on a balance board or cushion to improve proprioception and stability.
- Single-leg stance: Stand on one leg for short periods to improve balance and weight distribution.
- Functional Exercises:
- Stationary bike or cycling: Start with gentle cycling to improve knee mobility and strength.
- Step-ups: Step onto a low platform with the operated leg to improve strength and function.
- Mini-squats: Perform shallow squats to work on knee stability and strength.
- Flexibility and Stretching:
- Calf stretches: Stretch the calf muscles to prevent tightness and improve ankle mobility.
- Quadriceps and hamstring stretches: Stretch these muscles to maintain flexibility and prevent muscle imbalances.
- IT band stretch: Stretch the iliotibial band to reduce tension on the knee joint.
- Proprioceptive and Neuromuscular Training:
- Balance exercises on unstable surfaces: Use a balance pad or foam pad to challenge stability and proprioception.
- Coordination drills: Perform activities that require coordination and control, such as tossing a ball while balancing on one leg.
