1. Arthroscopic Lavage
Arthroscopic lavage is a procedure done to wash out any debris, blood, fluid or loose body from joints. It is commonly used to treat osteo-arthritis. Osteoarthritis of the knee can cause pain, stiffness, swelling and difficulty in walking. An arthroscopic washout is often combined with debridement, synovectomy, abrasion chondroplasty, micro-fracture decompression of worn out bony surfaces. In isolation, arthroscopic lavage contributes to about 20% of pain relief.
2. Proximal Fibular Osteotomy
Compared with knee replacement, PFO is a simpler surgical procedure, effectively relieves knee pain and also corrects the deformity for patients with medial compartment knee osteoarthritis (OA). PFO is performed by removing a 2 to 3 cm length of fibula bone at a site 6 to 10 cm below the knee. Full weight bearing and free mobilization are allowed after surgery. PFO relieves pain & corrects medial joint space by off-loading the weight bearing axis on the knee, thereby decompressing the medial compartment & loading the normal lateral compartment.
PFO is a simple, safe, fast and affordable surgery to relieve pain and improve joint function and the medial joint space in human knee osteoarthritis. PFO is a promising alternative in most developing countries because of their financial and healthcare delivery limitations. It may also constitute a promising alternative surgery for osteoarthritis of the medial compartment of the knee, especially for patients who cannot undergo TKA because of certain medical comorbidities. Furthermore, these patients can still undergo TKA in the future if it becomes necessary.
