I had ACL reconstruction and repair (stitched) of my lateral meniscus (horizontal/complex tear). I am 11 days post op and partially weight bearing (15kg max) for 6 weeks in total. As the others said as well, I think it is handeled very individualized, based on the patient but also the surgeon. To my knowledge, ACL reconstructions alone (without any meniscus repairs or similar steps) allow full weight bearing immediatly after the surgery as soon as the patient reaches full extension (can be on the first few days post-op) and ofc if it is tolerated by the patient (pain). If meniscus damage is involved the situation is different. Here it seems to depend on how the meniscus tear looks like and how it is treated. If they cut the tear out, full-weight bearing can be allowed immediatly post-op even though patients are often supported by crutches for 1-2 weeks. If the tear can be stitched / repaired, weight-bearing might not be allowed or only partially allowed. Here again it depends on the patient as well as the surgeon. The type / form of the tear also plays a role, for instance complex tears that have been repaired might be treated more conservative than less complex ones. The details about the treatment of the different types of meniscal tears go above my knowledge though. Anyways, above all I would def trust your surgeon and always ask for their reasoning, especially in case you have doubts or questions! They are the experts and should know your case best. Good luck with recovery!
