What happens in ACL Reconstruction Surgery
If your knee is stable and you are comfortable doing daily activities then you can delay the surgery for the whole life. But if your knee is unstable you should not delay it. Unstable knee causes repetitive cartilage injury whose recovery is irreversible. Cartilage injury leads to early arthritis.
Failure of an ACL reconstruction is often hard to describe. The patient can have complaints of knee instability, pain, stiffness, or the inability to return to desired activities.
ICD-10-CM Diagnosis Code Z42 Z42.
The signs of ACL graft failure can include swelling, pain within the knee, locking within the knee, a mechanical block (which can be due to a bucket-handle tear of the meniscus), lack of full motion, and difficulty with twisting, turning, and pivoting.
The graft failure occurring in the first 12 months following surgery is generally a result of non-traumatic causes and the failure after 12 months is mostly due to re-injury.
ICD-10 code Z98. 890 for Other specified postprocedural states is a medical classification as listed by WHO under the range - Factors influencing health status and contact with health services .
S83. 512A - Sprain of anterior cruciate ligament of left knee [initial encounter]. ICD-10-CM.
One of the known reasons for ACL allograft failure is premature return to sporting activities [2]. This may occur due to a occult or limited immune response that may delay healing of the graft. It may also occur because the allograft patient initially feels less pain and will want to progress faster through rehab.
Traumatic failure of ACL reconstructions has been estimated to occur in between 5% and 10% of cases (28).
The overall cumulative ACL failure rate was 11.9% (range, 3.2% to 27%). Conclusions: At least 1 in 9 patients undergoing ACL reconstruction will have rerupture or clinical failure at long-term follow-up.
Hamstring tendon grafts are one of the most commonly used grafts for ACL reconstruction. The semitendinosus tendon with or without gracilis tendon is harvested, from ipsilateral leg. They are used as quadruple stranded grafts and are comparable to native ACL.
The graft is at its weakest at 3 to 6 months – just when the patient is beginning to regain confidence. It is therefore essential that return to proper sport is delayed until 9 months post-op.
A revision ACL reconstruction is a second surgery needed to repair a torn anterior cruciate ligament. This is a more challenging operation for the orthopedic surgeon.
