Many (most?) commercial medical sites focus on “meniscus tear” as the leading cause of knee lock. But in my conversations with other knee lock sufferers, meniscus tears account for perhaps a minority percentage of hard locks. The resources below focus mainly on non-commercial knee lock information. Some pages are intended for medical practitioners, while others are for a general audience. The kneelock.com site is just getting started — I will be adding new resources on a regular basis. Check back often. If you have tips for unlocking a locked knee, or preventing knee lock, or link to a medical paper, or can refer a doctor or clinic experienced in knee lock, please leave a comment below. – John

One of the best knee-related resources on the ‘net. Great forum discussions, tutorials and papers.
“Interventional Orthopedics” providing non-surgical biologic therapies. Also Google “Prolotherapy for Knee” for a range of “tissue regeneration” resources that may (or may not) strengthen the Tib-Fib joint.
Short for “proliferation” therapy, Prolotherapy is a somewhat controversial nonsurgical ligament and tendon reconstruction, or regenerative injection therapy. “Prolotherapy works by stimulating the body’s own natural healing mechanisms to repair injured musculoskeletal tissue.” According to my correspondence with them, this medical group has “had some success” treating knee-lock symptoms.

Arthroscopic surgery of the meniscus is THE MOST COMMON ORTHOPEDIC PROCEDURE in the USA. Meniscus surgery, alone, is a $4 billion industry, performed 700,000 times per year. If my years of on-line conversational evidence reflects anything close to normative, then a significant number of meniscus surgeries are unnecessary shams. Indeed, there are numerous peer-reviewed academic studies all concluding that surgeries for torn and arthritic meniscus are generally worthless. Here are just a few.

MENISCUS and POPLITEOMENISCAL
A locking / popping knee could be the result of meniscus and/or popliteomeniscal issues. After years of conversations with kneelock sufferers, I’ve noted a range of severity in how people characterize their locking symptoms. I’ve noted that reports of less severe locking and persistent popping symptoms are sometimes correlated with successful meniscus repair surgery, while severe locking conditions (the “large bone movement and thunk” sensation) more often have no improvement after meniscus repair. This is just a personal observation and does not in any way reflect a medical opinion.
Here are some medical resources covering a range of these meniscal issues.
“MRI of intermittent meniscal dislocation in the knee” https://www.birpublications.org/doi/abs/10.1259/bjr/25044103
“Arthroscopic meniscus repair for recurrent subluxation of the lateral meniscus.” https://www.ncbi.nlm.nih.gov/pubmed/28258328
“Reconstruction of the Popliteomeniscal Fascicles for Treatment of Recurrent Subluxation of the Lateral Meniscus” https://www.sciencedirect.com/science/article/pii/S221262871630175X
