When can I run and play sport again after cartilage repair?

Why cartilage takes longer

Repair tissue and grafts keep maturing for many months after the knee feels comfortable. Running and cutting place high, repeated loads across the repaired surface, so returning too early risks damaging tissue that is not yet ready. This is why cartilage surgery has a longer return than, for example, a meniscus trim.

Milestones that usually come first

• No swelling after daily activity and exercise
• Full or near-full range of motion
• Thigh strength close to the other leg on testing
• Good balance and single-leg control
• Comfortable on the bike, cross-trainer and in the pool
• Pain-controlled hopping and jogging drills in the clinic

Your physiotherapist will usually progress from straight-line jogging to change of direction, then sport-specific drills, then training, before matches.

What changes the timeline

The technique matters: marrow stimulation, osteochondral grafts and cell-based repairs mature at different rates. Defect size and location, combined procedures such as ACL reconstruction or osteotomy, and your age and conditioning all play a part. Some patients return to running but choose lower-impact sport long term.

Training safely in Qatar

Plan the return so the hardest phase falls in the cooler months, or train indoors and early in the morning in summer. Hydrate well, as fatigue in the heat makes landing mechanics worse. Dr. Gelber reviews your progress at Aman Hospital and agrees each step of the return with you and your physiotherapist.
