Jan Jaśkowski points out that after one and two years, patients after arthroscopy felt similar to those treated conservatively.
- In the study he cites, real surgery did not improve pain or mobility more than sham surgery.
- Jaśkowski recommends good rehabilitation and an assessment of mobility in the feet, hips, and spine, because dysfunctions in these areas can cause knee symptoms.
- Andrzej Frydrychowski recommends regular movement and, in the case of excess weight, weight reduction and low-impact exercises such as swimming or riding a stationary bicycle.
- Henryk Różański describes intra-articular administration of hyaluronic acid as a method that may improve joint mobility and reduce pain.
What the authors write
After one and two years, patients after arthroscopy and conservative treatment felt similar; the initially small difference in pain after surgery disappeared.
In the study, real surgery did not improve pain or mobility more than sham surgery.
Jan Jaśkowski recommends seeking good rehabilitation and assessing mobility of the feet, hips, and spine when determining treatment for knee pain.
Jan Jaśkowski writes that dysfunctions of the foot or hip may cause knee symptoms.
Andrzej Frydrychowski points to regular movement as a way of supplying cartilage with nutrients from synovial fluid.
For excess weight, Andrzej Frydrychowski recommends reducing it and, at first, doing low-impact exercises such as swimming or riding a stationary bicycle.
Andrzej Frydrychowski identifies injuries and overloading as factors that harm cartilage and recommends avoiding them.
Paul Clayton links the risk of worsening cartilage condition with excess weight, chronic inflammation, and lack of movement.
Henryk Różański describes intra-articular administration of hyaluronic acid as a method that may improve joint mobility, cartilage nourishment, and reduce pain.
Henryk Różański states that oral and skin-applied hyaluronic preparations have only a theoretical justification.
Henryk Różański notes that the body does not direct orally absorbed ingredients precisely to the affected joint, and administration into the joint cavity may produce better therapeutic results.

A meta-analysis found that AD-MSC injections were associated with less pain and better function than control treatment, without a significant increase in adverse events.
Aim of the study: To systematically review randomized controlled trials and quantitatively evaluate the efficacy and safety of injections of autologous adipose-derived mesenchymal stromal cells (AD-MSCs) in patients with knee osteoarthritis (OA).
Results: Of the 1178 identified records, six randomized controlled trials, including 551 patients, were included. Compared with control, AD-MSC treatment was associated with lower WOMAC total scores at 3 months (mean difference [MD], -8.14; 95% confidence interval [CI], -13.33 to -2.95) and 6 months (MD, -8.07; 95% CI, -13.60 to -2.54), and lower pain VAS scores at 3 months (MD, -1.49; 95% CI, -2.45 to -0.54), 6 months (MD, -1.40; 95% CI, -2.08 to -0.73) and 12 months (MD, -1.80; 95% CI, -3.20 to -0.41). The pooled risk of any AEs was not significantly increased (risk ratio [RR], 1.12; 95% CI, 0.99-1.27), and SAEs were rare (RR, 0.48; 95% CI, 0.10-2.18). Intra-articular autologous AD-MSC injections for knee OA were associated with improvements in pain and WOMAC outcomes without a significant increase in AEs.

A meta-analysis of randomized studies found that mesenchymal cell injections improved pain and function after 6 and 12 months.
Aim of the study: The aim of this meta-analysis was to investigate the efficacy and safety of intra-articular injection of mesenchymal stem cells (MSCs) alone for the treatment of unoperated knee osteoarthritis (OA).
Results: 8 RCTs and 502 patients with OA were included in the study. Compared with the control group, MSCs significantly improved 6-month WOMAC [MD = 7.44, 95% CI = (1.45, 13.42), P = 0.01] and 12-month WOMAC [MD = 10.31, 95% CI = (0.96, 19.67), P = 0.03]. MSCs also improved VAS and KOOS at 6 and 12 months in patients with OA. Subgroup analysis showed more significant efficacy of adipose source and high doses of MSCs. There was no significant difference between the adverse events in the MSCs group and the control group (P > 0.05). Intra-articular injection of MSCs alone could significantly improve knee pain and dysfunction in patients with unoperated OA. MSCs are expected to be an effective treatment for OA with enhanced delivery efficiency.

The review indicates that exercise, weight reduction when needed, and education are the foundation of treatment, so methods other than injections and surgery are also available.
Results: Hip and knee OA are highly prevalent and disabling. Education, exercise and weight loss are cornerstones of management, complemented by NSAIDs (for patients who are candidates), corticosteroid injections, and several adjunctive medications. For persons with advanced symptoms and structural damage, total joint replacement effectively relieves pain.

The review compares arthroscopy with non-surgical treatment, including exercise and medications, showing that alternatives to surgery were studied.
Aim of the study: Arthroscopic knee surgery remains a common treatment for symptomatic knee osteoarthritis, including for degenerative meniscal tears, despite guidelines strongly recommending against its use. This Cochrane Review is an update of a non-Cochrane systematic review published in 2017.
Results: Sixteen trials (2105 participants) met our inclusion criteria. The average age of participants ranged from 46 to 65 years, and 56% of participants were women. Four trials (380 participants) compared arthroscopic surgery to placebo surgery. For the remaining trials, arthroscopic surgery was compared to exercise (eight trials, 1371 participants), a single intra-articular glucocorticoid injection (one trial, 120 participants), non-arthroscopic lavage (one trial, 34 participants), non-steroidal anti-inflammatory drugs (one trial, 80 participants) and weekly hyaluronic acid injections for five weeks (one trial, 120 participants). The majority of trials without a placebo control were susceptible to bias: in particular, selection (56%), performance (75%), detection (75%), attrition (44%) and selective reporting (75%) biases. The placebo-controlled trials were less susceptible to bias and none were at risk of performance or detection bias.
