I tore 3 of my 4 quads tendons off the top of my left patella whilst diving in the Red Sea on 25 Nov 19. My diving buddies helped me back through the flight and drove my car home from Manchester to Loughborough, arriving in the early hours of Mon 01 Dec. A&E on Monday morning, ultrasound scan on Thu 05, and surgery on Fri 06 Dec 19. I was in a fixed splint to keep my leg straight for 4 weeks, then another 4 weeks in an adjustable hinged brace to weekly increase the bend angle: 45, 60, 75 and 90 deg. My consultant said I could drive again when I could A, fit into the driving seat, and B, safely control the vehicle. I went back to work, and driving, in the final week wearing the hinged brace. I started physio classes in early Mar 20 and managed two before Covid closed everything, but used a 6-week furlough period from work to go on long walks in lieu of physio. I regained a full range of movement by mid-April, using physio exercises at home, and was able to do 10 km walks by mid-May 2020, but still cautious descending stairs. Finally got to see the physio again in Oct 20 and discharged with full range of movement and good strength; I resumed diving in Sep 20. I didn't ride again until May 21, but in Oct 21 took a 10-day trip to Spain and Portugal without knee issues.
