Can I still squat, lunge and play sport with chondromalacia patella?

Adjusting your gym session

The kneecap is under most pressure in deep bending with heavy load, and in exercises where the knee travels far forward over the foot. You do not have to stop leg training, but you may need to change it for a while:

• Squat to a box or bench at a depth that feels comfortable, then lower the box over the weeks
• Use leg press, Spanish squats, hip thrusts and Romanian deadlifts to build strength with less kneecap stress
• Swap deep walking lunges for shorter static split squats or reverse lunges
• Leg extensions can be used in a limited, comfortable range
• Reduce box jumps, burpees and jump squats until stairs and squats feel easy

Using pain as a guide

Mild discomfort during exercise that settles within 24 hours is usually acceptable. If the knee aches more the next morning, swells, or you start limping, the session was too much and the next one should be lighter. Keep a simple training note so you can see which exercises and loads your knee tolerates.

Returning to running and court or pitch sports

Running, padel, football and basketball add impact, cutting and deep lunging. A sensible return usually follows this order: comfortable stairs and squats, then easy running on flat ground, then faster running and changes of direction, then full training and matches. Many people manage this over a few weeks to a few months, depending on the severity of the cartilage changes and how strong the leg is.

When to get advice

See a knee specialist if the knee repeatedly swells after training, catches or locks, or if you are not progressing despite a sensible plan. At Aman Hospital in Doha, Dr. Pablo Gelber can assess the cartilage, kneecap tracking and leg strength, and work with your physiotherapist or coach on a realistic return to the activities you enjoy.
